SEO Chrome extensions — 40 keywords tracked, 637 extensions analyzed · Market data updated weekly
Market overview
What Developers Can Learn
Intelligence derived from tracked keywords across all SEO sub-keywords
Most Congested
Keyword research tools are oversaturated with Keywords Everywhere dominating at 1M users.
Massive user bases and strong ratings (4.2-4.5 stars) create high barriers.
Plagiarism checking also shows 1.8M search volume but limited extension differentiation.
Possible Openings
Technical SEO (27.9K monthly searches) and broken link checking (38.7K) remain underserved with high search volatility.
Robots.txt testing (11.4K) and SERP analysis (1.5K) represent niche opportunities where rising entrants like LinkAudit already show traction.
Local SEO has only 81K tracked searches.
Positioning Patterns
Top extensions maintain 4.2-4.5 star ratings with Keyword Surfer and Keywords Everywhere built on brand recognition.
AutoTDK achieves 4.4 stars with only 40K users, suggesting quality differentiation matters more than raw user count in this category.
