On-Page SEO Checker

It reads one page the way a search engine first sees it and runs dozens of checks in eight groups: title and meta description, headings, content and keyword use, links, images, structured data and social tags, technical basics such as canonical, indexing and mobile settings, and speed from Google PageSpeed Insights. Each check is marked Pass, Warning or Fail, with why it matters and how to fix it.

Each check earns full marks for a pass, half for a warning and none for a fail. Checks that affect search visibility more, such as an accidental noindex or a missing title, count for more than small polish items. The group scores and the overall score are weighted averages. It is a guide to what to fix first, not a prediction of rankings.

The keyword is optional. If you add one, the checker also tests whether it appears in the title, meta description, H1, a subheading, the first 100 words, the URL and image alt text, and whether the exact phrase is repeated so often that it reads as stuffing. A keyword counts as present when the exact phrase appears or, for several words, when all of its words do. Without a keyword, those checks are left out.

We flag titles outside 30 to 60 characters and descriptions outside 70 to 160. These are guides: Google actually cuts text by pixel width, and it sometimes rewrites titles and descriptions to suit the search.

The page can have hundreds of links, so we test up to 25 of its unique links, internal ones first, and tell you how many were checked. Links on sites that block automated requests are reported as blocked rather than broken.

This tool reads the HTML a server sends, like a basic crawler. If a page has almost no text in that HTML and relies on JavaScript to show its content, we cannot judge the content, headings, links and images fairly, so those checks are marked "not assessed" instead of failing. Google can render JavaScript, so this does not mean the page cannot rank.

Running the checker and reading every finding on screen is free with no sign-up. The PDF and Excel downloads ask for your name and email. We send those, with the page you checked and its score, to the 1Solutions team, who may contact you about the report and our SEO services, as you agree when you tick the box. We do not save the pages you check or the results, and the files are created in your browser. See our privacy policy for how we handle personal data.

Both hold the score, the group scores, your top 10 priority fixes and every check with what we found and how to fix it. The Excel file adds sheets for headings, links (with their status), images and keywords, and an Issues sheet with Owner and Done columns for your team to track the work. The PDF is easier to share with a client or manager. The PDF can only show Western characters, so use Excel for pages in other scripts.
