8 Best Web Platforms for SEO That Use AI to Boost Rankings Fast [2026]

That figure should make every SEO professional pause. The platforms that used to win on keyword stuffing and backlink volume no longer cut it. In 2026, the best web platform for SEO does three things simultaneously: it optimizes for Google, earns citations from AI engines like ChatGPT and Perplexity, and automates the heavy lifting so your team can focus on strategy.

This guide covers the 8 platforms that actually do all three. Each one has been reviewed for features, hands-on usability, pricing, and how well it handles the shift from traditional rankings to AI-generated answers. Whether you are an agency scaling multiple client accounts or a content team trying to close AI visibility gaps, one of these platforms fits your workflow.

What Makes a Web Platform the Best for SEO in 2026?

Before diving into the tools, it is worth understanding what separates a good SEO platform from a great one in 2026. The gap is no longer just about data volume or interface design.

The best web platform for SEO in 2026 should cover four foundations.

AI-Powered Features go beyond content scoring. They include automated technical fixes, AI-generated content briefs, and generative engine optimization (GEO) capabilities that help your brand get cited inside ChatGPT, Perplexity, and Google AI Overviews, not just ranked in the classic blue links. You can learn more about why this shift matters in our guide on what is AI SEO.

Technical SEO Foundations still matter enormously. Core Web Vitals, schema markup, mobile usability, crawlability, and site speed all feed into how both Google and LLMs interpret your content. A platform that automates these checks saves dozens of hours per month.

LLM Visibility and AI Search Indexing is the new frontier.

This means Bing Webmaster Tools indexing, structured data optimized for AI parsing, and active citation tracking are no longer optional extras. Our breakdown of how to rank high in LLMs covers this in detail.

Agency and Multi-Client Scalability rounds out the criteria. The best platforms include white-label reporting, multi-site dashboards, and automation pipelines that let one person manage twenty client accounts without burning out.

The difference between SEO, GEO, and AEO is also worth understanding before choosing a platform. You can read our full breakdown on SEO vs GEO vs AEO.

Tool Overview and Comparison Table

8 Best Web Platforms for SEO Using AI [Ranked and Reviewed]

1. Search Atlas: Best All-in-One AI SEO Platform

What Are Its Key Features?

Search Atlas is built around five tightly connected modules, and each one handles a distinct part of the SEO workflow.

OTTO SEO is the platform’s centerpiece. You drop a lightweight pixel snippet on your site and OTTO audits the domain, generates a prioritized fix queue and then deploys those fixes, including title tags, schema updates and heading restructuring, directly to your CMS after you approve them.

Content Genius handles AI content creation and optimization. It generates full briefs, outlines and drafts tied directly to your target keyword and SERP data then scores your content against the top-ranking pages. Unlike standalone content tools, it plugs into the same dashboard as your rank tracker and technical audit, so optimization and creation happen without tab-switching.

LLM Visibility Tracking is a standout feature in 2026. Search Atlas tracks how often your brand appears in AI-generated responses from ChatGPT, Claude, and Gemini and scores that visibility relative to your top competitors. This ties directly into the broader shift that most traditional SEO platforms are only beginning to address. For more context on why this matters, see our overview of the best AI SEO agents.

Topic Map Builder lets you plan content clusters by mapping topic relationships. Instead of chasing individual keywords, you build interlinking structures that establish topical authority, which both Google and LLMs reward heavily.

Backlink Analyzer and Competitor Research round out the suite. The database is smaller than Semrush’s 27 billion keywords, but the data aligns closely with Google Search Console figures in real-world testing.

Atlas Brain, the platform’s conversational AI agent, can run full competitive analyses, generate topical maps, and produce SEO reports in response to plain-language questions, similar to asking a senior SEO specialist a question and receiving a structured answer with actions.

How Was My Experience Using It?

Testing the $199 per month Growth plan on a live site showed that Search Atlas delivers strong automation. The OTTO workflow is simple. You connect the site, review the suggested fixes, approve changes in bulk, and OTTO applies them. On a site with more than 200 pages, the technical audit found issues that would have taken days to spot by hand.

The content editor is functional and well-integrated with the keyword data, though the output requires editing before publication. It is a draft accelerator, not a final article generator. The LLM tracking dashboard shows citation frequency and source attribution across AI platforms which is genuinely useful for closing gaps.

The platform’s speed was uneven during testing. Dashboards occasionally took longer to load than expected and a few reports timed out. Given the $199/month price point for the Growth plan, these friction points are worth noting. The platform is evolving fast, with regular feature releases, but current stability is a real consideration for production agency use.

Pricing

2. Semrush One: Best for Enterprise AI SEO and Competitor Analysis

What Are Its Key Features?

Semrush’s 26.8 billion keyword database and 43 trillion backlink index remain the largest in the industry, and those numbers matter for competitive research. But in 2026, the platform’s most significant move has been the launch of Semrush One, a bundle that pairs traditional SEO with a dedicated AI Visibility Toolkit.

Semrush Copilot is included free on all plans. It continuously monitors six core Semrush tools and surfaces personalized recommendations in your dashboard, ordering them by impact. Instead of manually hunting for ranking drops or keyword opportunities, Copilot flags what matters and explains why. This alone saves meaningful time each week in campaign management.

The AI Visibility Toolkit tracks how your brand appears in AI-generated answers across ChatGPT, Google AI Overviews, Google AI Mode, and Gemini.

The Semrush One Starter plan at $199/month bundles SEO and AI tracking. If purchased separately, those two toolkits would cost $239/month.

ContentShake AI generates full SEO-optimized articles using Semrush’s keyword intelligence. The content is informed by real competitive data. It knows which keywords your competitors rank for and builds content structured to close those gaps.

The Keyword Magic Tool covers 26.8 billion keywords across 142 geographic databases, and supports clustering, intent filters and long-tail expansion. For keyword research at scale, no competitor comes close to this depth.

Position Tracking monitors rankings across devices, locations, and search engine features simultaneously, including AI Overview presence and Featured Snippet capture rates.

Technical Site Audit crawls up to 100,000 pages on the Pro plan, flagging issues across 140+ SEO checks including Core Web Vitals, mobile usability and structured data completeness. The audit runs automatically on a schedule, so you catch regressions before they impact rankings.

For teams needing to understand their AI visibility gaps more deeply, our guide on AI visibility checkers walks through how to interpret and act on this data.

How Was My Experience Using It?

Semrush consistently delivers on data depth. The competitive intelligence features, including organic traffic estimates, keyword gap analysis, and backlink comparison, are the most reliable in the industry for directional research. The AI Visibility Toolkit adds a genuinely useful layer: you can see how often you are mentioned in AI answers versus competitors, and filter by prompt topic to find your weakest areas.

The interface takes time to learn. With 55+ tools across the platform, new users often feel overwhelmed during onboarding. The per-user seat pricing also adds up fast: a five-person team on the Guru plan pays $6,340/year once seats are factored in, not the $2,500/year the headline plan price implies. Factor that into your budgeting.

Pricing

3. Surfer SEO: Best for AI Content Optimization

What Are Its Key Features?

Surfer’s entire product philosophy is built around one question: what do the top-ranking pages have in common, and how do you match or exceed them? That question drives every feature.

The Content Editor is where most users spend the majority of their time. You enter your target keyword and Surfer scrapes the top-ranking results then builds a real-time scoring dashboard. As you write, the editor tracks keyword usage, heading structure, content length, NLP term density and internal link count. The Content Score climbs as you hit the recommended ranges. Surfer SEO has documented a correlation between Content Score and rankings. This makes it one of the few content tools with empirical backing rather than just theoretical SEO logic.

The Google Docs integration is a practical advantage for content teams. Writers do not need to leave Docs. The Surfer extension overlays recommendations directly in their environment. For agencies running writers across multiple articles, this removes adoption friction entirely.

Topical Maps help you plan content clusters systematically. You enter a seed topic, and Surfer generates a network of supporting content ideas organized by search intent and semantic relatedness. Building topical authority is one of the strongest signals for LLM citations, making this feature valuable beyond traditional Google rankings.

Surfer AI generates full articles on-platform. The output is structured to score well in Surfer’s own Content Editor, with headings, keyword distribution, and paragraph length calibrated for the target SERP. However, the Essential plan only includes 5 AI articles per month, and additional articles cost $29 each. The content also requires editing before publication.

The AI Tracker is a paid add-on at $95/month for 25 prompts. It monitors brand visibility in ChatGPT, Google AI Overviews, and Perplexity. It is newer and lacks historical depth compared to dedicated AI visibility platforms, but for Surfer users who want everything in one place, it works as a starting point.

One important limitation: Surfer is not an all-in-one platform. It does not offer deep backlink analysis or comprehensive technical SEO audits. Most professional SEOs use it alongside Ahrefs or Semrush for research, then use Surfer for content execution. That two-tool stack is the most common workflow.

How Was My Experience Using It?

The Content Editor is genuinely excellent. The real-time scoring feedback loop creates a productive rhythm for writing. You hit a keyword, watch the score move, adjust the heading, watch it move again. For teams producing SEO content at volume, this is the fastest way to improve on-page optimization without requiring deep SEO knowledge from every writer.

The Topical Map feature has improved significantly. Clusters now include intent labeling that distinguishes informational from commercial queries, which helps content strategists prioritize what to write first.

The AI article output needs editing. Surfer is clear about this and positions the tool as a draft accelerator. But teams expecting publication-ready copy will be disappointed. The $29/article overage charge is also a real cost consideration for high-volume content operations.

Pricing

4. SE Ranking: Best Budget AI SEO Platform for Agencies

What Are Its Key Features?

SE Ranking’s value proposition in 2026 is straightforward: get enterprise-level SEO tools and AI visibility tracking at mid-range pricing.

The AI Visibility Tracker is SE Ranking’s defining differentiator. It ships as three interlocked modules: the AI Overviews Tracker monitors Google’s AI snippets, the AI Mode Tracker handles Google’s conversational search results and the unified LLM Visibility module covers ChatGPT, Perplexity, and Gemini. Each module tracks brand mentions, unlinked references, citation sources, and competitor benchmarks. Critically, AI visibility data updates are included in existing SE Ranking subscriptions rather than sold as separate add-ons, which dramatically changes the total cost calculation compared to Semrush.

Rank Tracking covers 188 to 190 countries, significantly more than Semrush’s 120-country coverage, and monitors positions across devices, locations, and search engine features simultaneously.

Website Audit 2.0 uses an upgraded crawling engine with enhanced JavaScript rendering. It runs 115+ technical SEO checks and can crawl and flag issues across pages with dynamic content that older crawlers miss entirely.

Keyword Research taps into a 5.4 to 7 billion keyword database. That is smaller than Semrush’s 26.8 billion, but for most agency use cases, the coverage is comprehensive enough. The tool clusters keywords by intent and surfaces topic groups for content planning.

White-Label Reporting and Agency Pack are available as add-ons.

For agencies billing clients for monthly SEO reports, this is a direct improvement in revenue per hour.

Model Context Protocol (MCP) Integration enables direct connection to ChatGPT, Claude, and Gemini for code-free SEO insights, a 2025 feature that positions SE Ranking ahead of many competitors for workflow automation.

How Was My Experience Using It?

The interface is the most intuitive of any platform in this comparison.

That gap is real: onboarding a new team member takes hours, not days.

The AI Visibility Tracker covers the workflow well. The “No cited” filter, which shows queries where competitors are mentioned but you are not, is genuinely useful for building a content plan around AI citation gaps. Reddit users have called this feature “gold for content ideas.”

One limitation worth flagging:

Once you add the AI Search add-on for meaningful prompt volume and multi-engine coverage, the real cost sits closer to $150 to $240/month. Still competitive, but not as simple as the headline price suggests.

Pricing

5. Ahrefs: Best for Backlink Intelligence and AI Keyword Research

What Are Its Key Features?

Ahrefs built its reputation on backlink analysis and that foundation remains unmatched. But in 2026, the platform has evolved into a full-spectrum SEO suite with AI features woven throughout.

Backlink Analysis via Ahrefs’ Site Explorer remains the industry reference point.

For technical link audits and competitive backlink research, no competitor matches Ahrefs’ data depth.

Keywords Explorer covers 10+ search engines, including Google, Bing, YouTube, Amazon, and Baidu, with search volume, keyword difficulty, click data, and SERP history.

The keyword research workflow is designed specifically to find the pages and queries that break out of that 90%.

AI Content Grader compares your content against top-ranking pages and flags structural, keyword, and coverage gaps. The AI Content Helper then assists in rewriting sections to close those gaps without requiring a separate content tool.

Brand Radar AI tracks your brand’s presence across ChatGPT, Google AI Overviews, Perplexity, Gemini, and Copilot.

The data integrates into Site Explorer, so you can correlate backlink authority with AI citation frequency, a unique analytical view that no other platform offers in this way.

AI Search Intent groups SERP results by intent automatically, helping you understand whether a keyword cluster requires informational, commercial, or navigational content before you commit to writing.

Site Audit crawls your domain for 100+ technical issues and maps the internal link graph. The audit is thorough and well-suited to identifying crawl efficiency problems on large sites.

Content Explorer lets you search 16+ billion pages by topic, backlinks, organic traffic, or social shares. For content ideation and competitive benchmarking, this feature is faster than any alternative.

How Was My Experience Using It?

Ahrefs is the most comfortable platform to use for experienced SEOs. The interface is logical, data loads quickly, and the keyword and backlink workflows are the most refined in the industry. The transition to AI features has been handled smoothly. Brand Radar appears as a natural extension of the existing Site Explorer rather than a bolted-on module.

Brand Radar is still maturing. Ahrefs’ own CMO has acknowledged that the UI “still needs work” and that AI content sampling captures only a fraction of actual conversations. Monthly updates rather than daily refreshes also mean it is better for directional trend analysis than real-time citation monitoring. A dedicated tool like Wellows or Profound will outperform it on AI visibility depth.

The Content Kit (from $99/month) and Brand Radar add-on ($199/month) are separate purchases on top of your base Ahrefs plan, which pushes the total cost to $328/month for full AI visibility access on the Lite tier.

6. Wellows: Best for AI Search Visibility Tracking

What Are Its Key Features?

Wellows approaches AI visibility as an operational workflow, not just a reporting dashboard. The platform is built for teams that want to close citation gaps systematically rather than just observe them.

AI Brand Visibility Score is the platform’s central metric. It aggregates how often your brand is mentioned, cited and recommended across ChatGPT, Gemini, Perplexity, AI Overviews, and AI Mode, then normalizes that data into a single trackable score. You see whether your visibility is improving or declining across platforms and the score breaks down by platform so you can identify which AI engine underperforms relative to competitors.

Explicit Opportunities surface the specific content topics where competitor brands are being cited by AI platforms but your brand is not. Each opportunity includes the prompts triggering those citations, the domains being referenced, and structured content briefs for closing the gap. This turns AI visibility monitoring into an actionable content calendar.

Implicit Opportunities go deeper: they identify contextual mentions your brand could earn based on semantic relevance, even on topics where no direct competitor is currently dominating. This is particularly valuable for newer brands building AI citation presence from scratch.

Unlimited Outreach is included on all plans. Wellows identifies the verified publisher contacts for domains AI engines already trust and provides ready-to-send outreach templates. Instead of guessing which sites to pitch for coverage, you reach the exact publishers that will improve your AI citation profile.

KIVA AI Agent converts keyword research into full content strategies in under 30 minutes. The agent surfaces “hidden gem” keywords from your Google Search Console data, specifically queries where you have traction but no content, then builds a prioritized 7-day content plan with briefs optimized for AI readability.

Performance History tracks how your Citation Score, brand sentiment, and competitor share of voice change over time. Daily updates on Starter and above mean you catch shifts quickly, not on a monthly lag.

You can explore how tools like this fit into a broader AI visibility strategy in our guide on the best AI search visibility platforms.

How Was My Experience Using It?

Wellows is the cleanest platform in this roundup for teams whose primary concern is AI visibility. The dashboard loads fast, the Citation Score gives you an immediate read on where you stand and the Opportunity modules make it obvious what to do next. There is no ambiguity about whether your work is improving your AI presence. The historical performance graph shows the trend directly.

KIVA impressed the most. Running it on a site with stale keyword data, it pulled 23 underperforming keyword clusters from GSC, grouped them by intent, and output a structured content plan in roughly 35 seconds. The briefs are AI-citation-optimized from the start, which saves a separate round of optimization.

The Lite plan’s limitation to ChatGPT only is a genuine constraint for teams that need multi-platform coverage. You need the Starter plan at roughly $97/month to unlock Gemini, Perplexity, AI Overviews, and AI Mode simultaneously.

7. Writesonic: Best for AI Content Creation Combined with GEO Tracking

What Are Its Key Features?

Writesonic’s 2026 identity is built around a single insight: knowing where you are missing AI citations is only useful if you can fix the gap quickly. The platform combines the diagnostic and the remedy.

AI Article Writer is Writesonic’s most used feature. It generates full SEO-optimized blog posts from a keyword or brief, using GPT-4o alongside other models, and scores the output against SERP competitors before delivery. For teams producing 10 to 30 articles per month, the automation significantly reduces per article production time.

GEO AI Visibility Tracking is Writesonic’s defining feature in 2026. On Professional plans at $249/month and above, the platform tracks brand mentions, sentiment and citation frequency across 10+ AI platforms. The Brand Presence Explorer monitors whether AI models are citing you positively or negatively, which sources they rely on when discussing your competitors, and which prompts you are currently invisible for.

The Action Center converts visibility data into a prioritized to do list. When Writesonic detects that ChatGPT cites a competitor for “best CRM for remote teams” but never cites you, it generates a content recommendation targeting that gap, estimates the effort required and tracks whether your visibility improves after you act. This closes the loop between monitoring and execution.

SEO Checker and Optimizer scores your existing content from 0 to 100 based on keyword density, structure and readability. A one-click “Improve SEO” button applies AI fixes to underperforming content, useful for quickly refreshing older articles without rebuilding them from scratch.

Google Search Console and Ahrefs Integrations pull your existing keyword data and site performance directly into Writesonic’s dashboard, removing the need to export and re-import data across tools.

One important pricing note: GEO tracking, the Action Center, and sentiment analysis are locked behind the Professional plan at $249/month. The Lite ($49) and Standard ($99) plans focus on content generation only.

How Was My Experience Using It?

Writesonic’s content generation is fast and structurally sound for SEO. Articles come with clear headings, natural keyword placement, and appropriate internal linking suggestions. They need editing, but less than the average AI writer’s output.

The GEO features at the Professional tier are genuinely useful. The combination of citation gap detection and content recommendations in one interface is efficient. The competitor sentiment feature was the most surprising: seeing that a competitor is mentioned enthusiastically while your brand is mentioned cautiously, or not at all, triggers a specific kind of content urgency that raw traffic data never does.

The interface packs a lot in: content generation, SEO audit, GEO dashboard, AI chat, and publishing workflows all share space. New users will need a week of hands-on use before the layout feels intuitive.

Pricing

8. Profound: Best Enterprise AI Visibility Platform

What Are Its Key Features?

Profound was built for organizations where AI visibility is not a nice-to-have metric but a revenue-critical one. Fortune 500 brands use it because the platform’s data infrastructure exceeds what any other tool in this comparison can deliver at scale.

Answer Engine Insights is Profound’s core module. It tracks how your brand appears across ChatGPT, Perplexity, Gemini, Claude, Microsoft Copilot, Grok, Meta AI, DeepSeek, and Google AI Overviews. The platform processes 100 million+ AI search queries per month and sources data from real consumer sessions, not API simulations. That distinction matters: consumer-facing AI interface behavior often differs from what API queries return, and Profound’s data reflects what buyers actually see.

Prompt Volumes is a research tool that shows how often real users ask AI platforms specific questions in your industry. Instead of guessing which queries drive AI recommendations, you see actual demand data ranked by frequency. This shapes content strategy at a level of precision that search keyword tools cannot match for AI-native queries.

Agent Analytics tracks how AI crawlers such as GPTBot, ClaudeBot, and PerplexityBot visit your site, which pages they access, and how that correlates with brand mention frequency. You can see whether your content changes are actually influencing AI crawl behavior, a diagnostic capability unique to Profound.

Shopping Visibility monitors how your products appear in ChatGPT Shopping results, a newer AI shopping discovery surface that most visibility tools do not yet cover.

Competitive Intelligence lets you track multiple competitors simultaneously.

SOC 2 Type II compliance, SSO/SAML, role-based access, and an enterprise API for custom workflows make Profound suitable for organizations with security and compliance requirements that most AI visibility tools do not support.

For a deeper look at how tools like Profound fit into an agency’s visibility strategy, our guide on AI visibility tools for agencies covers the selection criteria in full.

How Was My Experience Using It?

Profound is not a self serve tool you can spin up in 20 minutes. The onboarding requires a sales conversation, a scoping call, and a structured setup process. For enterprise teams with dedicated SEO or brand marketing resources, that investment pays off quickly. The depth of visibility data and the specificity of the Conversation Explorer insights justify the cost at scale.

The Conversation Explorer is genuinely novel. Seeing real user intent, such as “What are the most reliable AI SEO platforms for agencies under $500/month?” ranked by actual prompt volume with your brand’s mention rate for each query, changes how content teams prioritize their work. You are no longer planning against estimated keyword volume. You are planning against documented AI demand.

The pricing is enterprise only in practice. The Lite plan at $499/month with 50 prompts is entry-level and teams needing full multi platform coverage move to $2,000/month and above. For small agencies or SMBs, Wellows or SE Ranking deliver similar category tracking at a fraction of the cost. Profound earns its position only when brand visibility at scale is the primary business priority.

Key Features to Look For in an AI-Powered SEO Platform

With eight solid tools now reviewed, here is a practical checklist for narrowing your choice.

AI Content Optimization and Keyword Research

Look for real-time content scoring tied to live SERP data, NLP-based term recommendations, and topical cluster mapping. The best platforms, including Surfer, Search Atlas, and SE Ranking, build their content briefs directly from competitor page analysis, not generic AI suggestions.

Schema Markup and Structured Data Support

FAQPage, HowTo, Article and ItemList schema make your content machine-readable for both Google and LLMs. Platforms that include schema validation in their technical audit such as Semrush, SE Ranking and Search Atlas, save you from deploying structured data with errors that undermine both SERP features and AI citations.

LLM and AI Overview: Visibility Monitoring

This is the non-negotiable feature in 2026. If your platform cannot tell you whether ChatGPT or Perplexity is citing your brand, you are optimizing blind for roughly 25% of the search market that has already migrated to AI-generated answers. See our breakdown of what GEO is for the full context on why this matters.

Technical Audit, Core Web Vitals, and Site Speed

Page speed affects both Google rankings and how efficiently AI crawlers index your content. Your chosen platform should run automated technical audits, flag Core Web Vitals failures, and, ideally, integrate remediation suggestions alongside the data.

How to Choose the Right SEO Platform for Your Needs

Solo Creators and Freelancers

SE Ranking’s $52/month annual plan covers keyword research, rank tracking, and AI visibility tracking in one subscription. Surfer SEO at $79/month on the annual plan is the better pick if content optimization is the primary need and you already use Ahrefs or Semrush for research.

SMBs and Growing Teams

Search Atlas at $99 to $199/month replaces multiple separate subscriptions. Writesonic at $249/month makes sense if high-volume content production and AI visibility monitoring are equally important. The key question: Do you need to execute SEO or monitor AI citations? Search Atlas executes, Writesonic monitors and generates.

Agencies Managing Multiple Clients

SE Ranking and Search Atlas are the two strongest options here. SE Ranking’s white-label reporting and transparent pricing work for agencies that value cost predictability. Search Atlas’s OTTO automation works for agencies that want to deliver more SEO output per hour of labor.

Enterprise and Large Organizations

Semrush One, priced from $199 to $499/month, handles the SEO foundation. Profound at $499 to $2,000+/month handles AI search visibility at the depth and compliance level that enterprise teams require. Using both in parallel is the most common enterprise stack.

FAQs

Conclusion

There is no single best web platform for SEO that works identically for every team. But there are clear winners by use case.

Semrush One is the most complete platform for teams that need traditional SEO depth and AI visibility in one subscription. The database size, competitive intelligence, and Copilot AI justify the premium for serious SEO operations.

Search Atlas is the best value all-in-one for agencies that want to automate execution, not just research. OTTO SEO’s ability to deploy fixes directly to client sites is the clearest differentiation from every other tool in this list.

Wellows is the best entry point for teams whose primary concern is AI search visibility. At $37/month with daily tracking, citation gap analysis, and a 7-day free trial, it is the most accessible way to start measuring and improving your brand’s presence across ChatGPT, Gemini, and Perplexity.

SE Ranking earns the best-value award for agencies and SMBs who need comprehensive SEO capabilities with AI tracking included rather than charged as an add on.

Most of the best SEO platforms offer a free trial or a limited free plan. A good way to choose is to test your site in two or three tools for a week and compare the gaps each one finds. The best tool is not the one with the most features. It is the one that finds the most useful issues for your site.
