What the on-page SEO checker tests
The checker fetches your page and evaluates the elements search engines rely on: the title tag and its length, the meta description, a single clear H1 and supporting H2s, image alt text, the canonical tag, a mobile viewport, HTTPS, Open Graph tags, whether the page is indexable, and how much real content it has. Each check is graded pass, warning or fail and explained in plain language.
Why on-page SEO is the foundation
Backlinks and authority matter, but they cannot rescue a page that confuses search engines. Clear titles, correct headings, descriptive alt text, a valid canonical and a mobile-friendly, indexable page are the foundation every ranking page shares. Fixing on-page issues is usually the fastest, cheapest win in SEO, and this tool shows you the exact list.
From a single page to your whole site
Auditing one page is a great start, but real sites have hundreds of pages with the same issues repeated at scale. When you are ready, a full-site crawl finds broken links, redirect chains, duplicate titles and orphan pages across every URL and tracks a health score over time, so you fix problems site-wide instead of one page at a time.
Frequently asked questions
Is the on-page SEO checker free?
Yes, you can audit any single page for free with no signup. A full-site crawl is also free on every plan.
What does the SEO score mean?
The score is a weighted summary of the on-page checks. A higher score means more checks pass. It is a quick health indicator, not a ranking guarantee, so focus on fixing the failed and warning items.
What does the checker actually look at?
Title and description, headings, image alt text, canonical, mobile viewport, HTTPS, Open Graph, indexability and content length, among other on-page factors. Each result explains what was found and how to improve it.
How is this different from Google PageSpeed Insights?
PageSpeed focuses on performance for one page. This checker focuses on on-page SEO across many factors, and the full platform can crawl your whole site and track issues over time.
How often should I run an SEO check?
Check important pages after you publish or edit them, and audit your whole site on a regular schedule so new issues are caught early.
