What Developers Can Learn
Intelligence derived from tracked keywords across all Seo Analysis sub-keywords
Most Congested
The top 3 positions are dominated by established brands with massive user gaps—Similarweb leads with 1M users at 4.7 stars, while the #2 has 200K users and #3 only 10K users at 4.0 stars.
This 100x disparity suggests users are fragmented across the category rather than loyal to one tool.
Breaking in requires competing against brand recognition and proven track records.
Possible Openings
Adjacent keywords like Domain Authority Checker (139.8K monthly searches) and Local Seo (81K monthly searches) offer substantial search demand with potentially lower competition than the main 'Seo Analysis' space.
These niche angles may allow new extensions to gain traction without directly challenging category giants.
Positioning Patterns
All top 5 extensions include 'SEO Checker' or 'SEO Analyzer' in their names, combined with descriptive terms like 'Audit', 'Analysis', or 'Tool'.
Ratings cluster tightly between 4.0-4.7, with the market leader (Similarweb) commanding both the highest user count and highest rating—a quality signal that users prioritize trust in this category.
