SEO Checker: SEO + GEO Readiness Score

A domain or page address is entered; the tool reads the page, the HTTP headers, robots.txt, the sitemap and llms.txt, takes mobile and desktop measurements with PageSpeed Insights and crawls pages chosen from the sitemap. The result shows the overall score and letter grade, the SEO and GEO half scores, the findings of 303 rules and the action plan.

The overall score has four components: rule checks 40% (the average of the SEO and GEO half scores), Lighthouse mobile 30%, Lighthouse desktop 15%, real-user data (CrUX) 15%. The share of a component that cannot be measured is redistributed proportionally and noted in the report. Every critical issue takes 3 points off the overall score, at most 15 in total.

The letter grade summarises the overall score: A (90 and above) Excellent, B (80–89) Good, C (65–79) Fair, D (50–64) Weak, E (below 50) Critical. Because the same scoring applies to every scan, the grade makes the effect of changes easy to follow.

Yes. No sign-up or card details are asked for. Every audit uses 1 credit; the daily credit is 3, 10 for customer panel members, and renews at midnight, Istanbul time. The same address is answered from a 24-hour cache without using a credit.

The entered page is checked against every rule; for the site-wide rules, pages spread across sections of the sitemap are also read: up to 10 in guest scans and up to 25 for customer panel members. Duplicate titles and descriptions, orphan pages, link depth and thin content are calculated from these pages.

Both open with a customer panel membership. For competitor comparison a second address is entered; the competitor is scanned as a single page with the same rules and category scores are shown side by side (2 credits). Scan history lists the date, score and grade per domain; older reports open again. In guest scans only the last scan is remembered in this browser.

It turns every issue and warning in the report, with details and solutions, into one text that can be given to coding agents such as Claude Code, Codex or Cursor. The text carries the priority order, the rule IDs and safe working rules (no unapproved design changes, no secrets in code, verification after every step).

The GEO score shows how ready the site is to serve as a source for AI answer engines (ChatGPT, Gemini, Perplexity): bot access and llms.txt, structured data, content that answers directly and trust signals. A low GEO score can mean you are not cited in AI answers even when you do well on Google.

When a rule has no data in that scan it is shown as information and left out of the score: Lighthouse rules if Google PageSpeed could not measure at that moment, real-user data if the site has too little Chrome traffic, site-wide rules if there is no sitemap. No estimated values are written.

On the result screen your e-mail address is verified with a one-time code; the detailed PDF is sent to that address. The PDF holds a cover with the grade, an executive summary, the action plan, Lighthouse and real-user data, category pages and the coding agent brief.

Every report carries an unguessable number. When the number is checked at our verification endpoint, it returns the domain, date and tool and nothing else. That lets you see whether a report presented to you was really produced by this tool.

The page is re-read by our server on every scan; the same address is cached for 24 hours and the result screen shows when a new scan opens. Customer panel members can request a new scan once the cached result is older than an hour.
