What is Meant by Competitor Analysis in SEO?
Competitor analysis in SEO is the process of reviewing the websites that rank higher for your target keywords. It involves studying their content, keywords, backlinks, and technical setup to understand why they perform well and where you can do better.
This becomes even more useful when paired with digital PR for AI search visibility, since it shows how competitors are appearing in AI-generated search results as well as traditional rankings.
