What the SEO checker audits
Title tag length (aim for 30–60 characters) and meta description (70–160); the number of H1s and the H1–H3 heading outline; canonical URL; robots meta tag and X-Robots-Tag header (a stray noindex is the most expensive SEO mistake there is); html lang and hreflang tags; mobile viewport; Open Graph and Twitter Card tags; images missing alt text; internal and external link counts; word count; JSON-LD structured data types; page size, server response time and HTTPS.
How to read the score
The score is the share of checks the page passes, so 100 means every technical on-page basic is in place — not that the page will rank first. Rankings depend mostly on how well the content answers the search, on links and on page experience. Treat the score as a checklist: fix every failure on your money pages, then spend your time on content and links.
The fixes with the biggest payoff
Put the main keyword near the start of a unique title for every page. Write a meta description that sells the click — Google rewrites it often, but a good one still lifts CTR. Use exactly one H1 that matches search intent. Set a self-referencing canonical on every indexable page. Add descriptive alt text to meaningful images (it is also an accessibility requirement). Add structured data such as Organization, Product, Article or FAQPage — our schema markup generator writes it for you.
Frequently asked questions
Is this SEO checker really free?
Yes, with no signup or limits on the number of pages you audit. Each analysis checks one URL.
Does it check my whole site?
No. It is a single-page on-page audit. Run it on your homepage and on each important template (category, product, article).
Why does the page show “noindex” when it is indexed in Google?
Check both the robots meta tag and the X-Robots-Tag header — this tool reads both. If noindex is present, Google will drop the page on its next crawl.
Should a page have only one H1?
Google says multiple H1s are fine technically, but one clear H1 that states the topic is still best practice for both users and SEO.
