What Developers Can Learn
Intelligence derived from tracked keywords across all Page Authority Checker sub-keywords
Most Congested
With only 23 active extensions and a 0.022 concentration ratio, the market is highly open.
However, established players like Free DA PA Checker Bulk (10K users, 4.4) and Domain Authority Checker (9K users, 4.4) dominate by rating strength.
Competitors hold comfortable user bases, making differentiation essential for visibility.
Possible Openings
Domain Authority Checker (139.8K searches) and Local SEO (81K searches) are adjacent keywords with substantially higher search interest and lower direct competition.
These represent opportunities for bundled SEO tool offerings rather than standalone PA checkers.
Positioning Patterns
The top 3 extensions all focus on Domain Authority rather than Page Authority specifically, creating a potential naming gap.
All top extensions maintain 4.4 ratings and use straightforward naming combining DA/PA with Checker.
Bulk functionality and SERP integration appear as differentiating features among rising competitors.
