What Developers Can Learn
Intelligence derived from tracked keywords across all Seo Audit sub-keywords
Most Congested
The 0.354 concentration ratio signals an open market, yet 'Website SEO Checker' dominates with 100K users and a 4.6 rating—creating a high bar for newcomer credibility.
The gap between the leader's 100K users and the #3 extension's 50 users reveals extreme user concentration among the top.
With only 24 active extensions, competitive density is low, but earning trust requires matching the top performers' feature depth.
Possible Openings
Adjacent keywords like 'Local Seo' (81K searches) and 'Domain Authority Checker' (139.8K searches) offer lower competition while serving specialized SEO needs.
'Plagiarism Checker' (1.8M searches) represents a massive adjacent vertical with minimal overlap to current 'Seo Audit' competitors, presenting a viable diversification path for established extensions.
Positioning Patterns
The top 3 extensions share descriptive naming conventions with 'SEO' and 'Audit' prominently featured.
Rating quality is critical—the average top 5 rating sits at 4.7.
Notably, 'Visual SEO Audit' achieves a perfect 5.0 with just 50 users, suggesting niche specialization can overcome user count disadvantages.
New entrants like 'SEO Audit Pro' and 'GMB Audit' signal developer interest in this space.
