Are backlinks still king in local SEO, or is the game changing? A key debate over social signals vs. links continues, do traditional backlinks still reign supreme in rankings, or are social signals and customer reviews becoming the driving force?

While backlinks have long been SEO’s backbone, rising social engagement and user-generated content challenge their dominance. This article explores how social signals, reviews, and backlinks impact local SEO and which factors truly drive local search visibility.

What is the primary role of backlinks in local SEO?


Understanding Local SEO: Core Factors & Google’s Perspective

Local SEO focuses on optimizing a business’s online presence to rank in location-based searches, ensuring that nearby customers can easily find relevant products or services. Whether it’s “best coffee shop near me” or “plumber in [city],” local SEO helps businesses appear in local search results.

Mastering the following primary ranking signals helps businesses improve visibility in local searches and attract nearby customers.

Primary Ranking Signals

A strategic mix of GMB optimization, citations, reviews, and backlinks can significantly boost local rankings.

Google My Business (GMB) Optimization

  • Ensure complete and accurate business information, including name, address, phone number (NAP), and website.
  • Regularly update the profile with posts, photos, and detailed service descriptions.
  • Select the most relevant categories and business attributes to enhance search visibility.

Local Citations & Directories

  • Ensure business listings are on credible, authentic, and industry-relevant platforms that enhance local search visibility.
  • Consistency in Name, Address, and Phone Number (NAP) across all listings.

Reviews & Social Proof

  • Powerful, high-impact reviews on Google and trusted third-party platforms establish credibility and trust.
  • Proactive engagement with customer feedback through timely responses strengthens brand reputation.
  • Dynamic social media interactions and compelling user-generated content amplify visibility and influence.

Backlinks & Authority Signals

  • Authoritative local backlinks from reputable sources enhance domain strength and search rankings.
  • Strategic mentions in local news, blogs, and industry-specific websites establish credibility and trust.
  • Contextually relevant links hold greater value than sheer volume, reinforcing local search impact.

Google considers these signals collectively to determine local search rankings, making it crucial to balance social signals vs. links in a well-rounded strategy.


Backlinks are links from external websites pointing to your page, signaling credibility and authority to search engines. In local SEO, these links help validate a business’s relevance within its geographic area.

In SEO, backlinks are among the most substantial ranking factors because they help search engines assess a website’s trustworthiness and relevance. A strong local backlink profile helps businesses rank higher in local search results by reinforcing industry relevance.

In local SEO, backlinks go beyond general authority-building, they validate a business’s relevance within its specific geographic area. Search engines, like Google, analyze these links to determine how well a business is connected within its community.

However, the debate on social signals vs. links is growing as businesses explore alternative ranking methods. While backlinks still hold power, social engagement is now a key player.

Impact on Local Rankings

  • High quality backlinks from authoritative sites boost domain authority (DA) and improve organic rankings.
  • Local backlinks (from nearby businesses, directories, or local news sites) enhance location based visibility and credibility.
  • A diverse backlink profile strengthens a website’s overall trustworthiness in Google’s eyes.

The Shift in SEO: Are Links Losing Their Grip?

Backlinks have always been a top-ranking factor in SEO and will continue to hold significant influence. However, Google now prioritizes a more holistic approach, where user engagement and overall business reputation play a crucial role.

Instead of relying solely on backlinks, businesses must focus on building a strong online presence through customer interactions, social proof, and local credibility to stay competitive in search rankings.

Google’s Growing Focus on User Engagement

Google now emphasizes user engagement as a key ranking factor, prioritizing metrics like Click-Through Rate (CTR), which tracks how often users click on a business listing, Dwell Time, and Bounce Rate.

✅ According to Backlinko’s analysis of 11.8 million Google search results, pages with high user engagement tend to rank higher because Google views them as more relevant.
📈The study found that the top ranking page in Google gets 31.7% of all clicks, highlighting the importance of CTR in rankings.

What Are Social Signals? The Debate Over Their SEO Impact

Social signals refer to engagement metrics such as shares, likes, comments, and brand mentions across social media platforms. These interactions indicate a brand’s reach and influence online.

Direct vs Indirect Impact on Local SEO

🔹 Google’s Official Stance: Google’s John Mueller has consistently stated that social signals, such as likes and shares, are not direct ranking factors in Google’s search algorithm. In a 2015 discussion, he clarified that while social posts can appear in search results, they do not directly influence rankings.

🔹 Indirect SEO Benefits: While not a direct ranking factor, social signals impact SEO in several ways:

📈 Brand Authority: Increased social engagement builds credibility, making users more likely to visit your site.
🎯 Click Through Rates (CTR): High engagement on social media can drive organic traffic, improving user signals that Google values.
🔗 Link Building: Viral content gets shared widely, increasing the chances of earning backlinks from reputable sites.

Do Social Signals Influence SEO? The Debate Continues

Studies show conflicting results about social signals vs. links and their impact on rankings. Some research suggests no direct connection, while others highlight a strong correlation between high social engagement and better rankings.

🔹 Why Social Signals Matter for SEO:

1️⃣ Increases Organic Traffic: Engaged social media audiences drive referral traffic, indirectly boosting search rankings.
2️⃣ Builds Links: Content shared frequently on social platforms increases backlink opportunities, strengthening authority.
3️⃣ Boosts Domain Authority: Active, high engagement social media accounts can be interpreted as more trustworthy by search engines.

While social signals alone won’t rank a business, their role in driving traffic, engagement, and backlinks makes them an essential part of a well rounded SEO strategy.

Businesses should focus on quality content, audience engagement, and strong social media presence to enhance their local search visibility.


Customer Reviews: The Social Proof That Drives Local SEO Rankings

Customer reviews serve as pivotal social proof, significantly influencing local SEO rankings.​

Why Reviews Matter for Local SEO:

  • Trust and Credibility: A substantial 71% of consumers avoid businesses with average ratings below three stars, underscoring the critical role of positive reviews in establishing trust. ​
  • Increased Click Through Rates (CTR) and Conversions: A stellar 5 star rating can boost clicks from the Google Local Pack by 25%, highlighting the direct correlation between positive reviews and user engagement. ​

Google’s Algorithm: How Reviews Affect Search Visibility

Google considers customer reviews a critical ranking factor in local search results, particularly for businesses appearing in the Google Local Pack (the top three business listings that show up in location based searches).

Reviews help search engines determine a business’s trustworthiness, relevance, and authority in its industry.

1. Review Signals and Local Pack Ranking

According to Moz’s Local SEO Ranking Factors Study, review signals account for 16% of how Google ranks local businesses. This includes:

  • Review Quantity: The total number of reviews a business has.
  • Review Quality: The overall rating score (e.g., 4.5 stars vs. 3 stars).
  • Review Recency: How frequently new reviews are posted.
  • Review Diversity: The number of reviews on Google, Yelp, Trustpilot, Bark, and other local review sites.

Google favors businesses with a high volume of recent, positive reviews because they indicate an active, well regarded business that is engaging with customers.

2. Reviews Improve Click Through Rates (CTR) and Engagement

Positive reviews enhance Click-Through Rates (CTR) and engagement. Research indicates that businesses with higher ratings attract more clicks and interactions in search results.

A strong CTR signals to Google that users find the business valuable, contributing to improved rankings.

3. More Reviews = Stronger Local Relevance

A higher volume of reviews strengthens local relevance. Google prioritizes businesses with active community engagement, and reviews act as digital word-of-mouth, reinforcing a business’s popularity and significance within its location.

For example:

  • A restaurant with 500+ reviews mentioning “best brunch in NYC” is more likely to rank for “best brunch near me” than one with only 20 reviews.
  • A dentist receiving regular patient feedback appears more active and trustworthy than a competitor with outdated reviews.

4. Responding to Reviews Strengthens SEO

Google encourages businesses to actively respond to customer reviews, as it signals engagement and customer service quality. Businesses that reply to reviews at least 25% of the time generate 35% more revenue than those that don’t.


Both backlinks and social signals play a role in local SEO, but their impact differs. While backlinks have long been considered SEO powerhouses, social signals have emerged as an engagement driven factor that enhances visibility.

Understanding how they complement each other can help businesses maximize their local search performance.

Backlinks: Traditional SEO Powerhouses

Backlinks remain a cornerstone of SEO, especially for local businesses aiming to establish authority and trust. However, as search algorithms evolve, social signals are gaining traction as complementary factors that enhance brand visibility and engagement.

🔹 High DA backlinks improve ranking authority:

Backlinks from high domain authority (DA) websites act as trust signals for Google. They tell search engines that a business is reputable and deserves higher rankings in search results.

🔹 Local backlinks strengthen geo targeted SEO:

Getting links from local sources (e.g., news sites, directories, local blogs) improves local relevance and visibility in geo specific searches. Businesses with strong local link profiles are more likely to rank in the Google Local Pack.

📊According to a Backlinko’s comprehensive guide on Google’s 200 Ranking Factors emphasizes the significance of backlinks, noting that the number of referring domains is one of the most important ranking factors in Google’s algorithm.

Social Signals: The New Age Influence on Local SEO

While social signals don’t directly influence rankings, their ability to drive traffic and engagement can indirectly boost SEO performance.

🔹 Increased brand visibility through social media shares:

Content that is widely shared on social platforms reaches more users, increasing brand awareness and organic search demand.

🔹 Higher engagement rates signal relevance to search engines:

Although Google doesn’t consider social signals a direct ranking factor, high engagement (likes, shares, and comments) can drive traffic, increase click through rates (CTR), and boost brand authority.

📊 ​A comprehensive study by CognitiveSEO analyzed over 23 million social media shares and found a strong correlation between high social engagement and improved search rankings.

The Verdict: Social Signals & Backlinks Work Together

While social signals don’t replace backlinks, they amplify visibility and engagement. Backlinks remain a primary ranking factor, but businesses leveraging both strong link building and social engagement gain a competitive edge in local search.

The social signals vs. links debate highlights local SEO strategies’ evolution. To maintain strong rankings, businesses should integrate both into their SEO plans for the best results.
