About SEODuel

SEOduel compares a website's SEO against a competitor's side by side. You enter your site and a competitor, or ask it to find SEO rivals, and it checks on-page and technical signals such as title tag, meta description, H1 and heading hierarchy, image alt tags, content depth, Open Graph tags, HTTPS, mobile viewport, sitemap, noindex directives and page speed, then names a winner with category scores.

Keyword Battle tracking and ranking shift alerts extend this to real-time monitoring, and results can be emailed as an SEO report or downloaded as a Markdown report formatted to paste into Cursor, Claude or ChatGPT for generating fixes. The page lists 25+ ranking signals, 14 on-page checks and priority levels (critical, warning, good), and says it uses real page data rather than estimates.
