Free tool — SEO Checker

Enter any page and we'll check the on-page basics Google relies on — titles, headings, canonicals, structured data, social tags, robots.txt and sitemap — with a fix for each.

How to use the results

A plain-English guide

Website audit →

Fix the red items first

Items marked Fix can stop a page ranking at all — a missing title, a noindex tag, an error status or no HTTPS. Items marked Improve are missed opportunities: descriptions that will be cut off, a thin page, or no structured data.

What this checker can't see

It reads the page's HTML the way a search engine first sees it. Content that only appears after JavaScript runs, your backlinks, and how you actually rank are outside its view — for those you need Google Search Console and a full site crawl.

Good SEO is mostly clarity

A clear title, a single H1 that matches it, sections with descriptive headings, and a description that tells people what they'll get. Write for the person searching first — search engines reward pages that answer the question well.

Questions

How is the score calculated?
Each check counts equally: a pass scores fully, 'Improve' scores half, 'Fix' scores zero. It's a quick health indicator for one page, not a ranking prediction.
Why did it say it couldn't reach my site?
Some sites block automated requests, take longer than 10 seconds to respond, or are behind a login. Private and internal addresses can't be checked.
Does it check my whole website?
No — one page at a time. Our website audit crawls every page and adds speed, UX and conversion checks.
