How it works
- Enter the page URL (for example
https://example.com/page) and your target keyword. - The tool fetches the actual page over HTTP, just like a search crawler, and parses its HTML.
- It checks each on-page location for the keyword and measures its density across the body text.
- You get a score with a pass/warn/fail breakdown showing exactly which placements are present or missing.
What it checks
- Title tag — whether the keyword appears, and ideally near the front.
- H1 heading — the main on-page heading reflects the target term.
- URL slug — the keyword is present in the address path.
- Meta description — the term is used in the snippet that shows in search.
- First paragraph — the keyword appears early in the body copy.
- Keyword density — how often the term occurs relative to total words.
- Subheadings & ALT text — supporting placements in H2–H6 and image descriptions.
Common use cases
- Optimizing a target page — confirm a page actually targets the keyword you chose.
- Fixing a page that won't rank — find the missing placements holding it back.
- Briefing writers — turn the checklist into clear editing instructions.
- Avoiding over-optimization — spot when density is high enough to look like stuffing.
Example
Run the page example.com/best-running-shoes against the keyword best running shoes and you might see green checks for the URL and H1, a warning that the keyword is missing from the meta description, and a note that density is 0.4% — a signal to weave the term in a little more naturally.
Frequently asked questions
Is the On-Page SEO Checker free?
Yes — completely free, with no signup and no limits. Check as many keyword-and-page combinations as you like with real, live data.
Does a perfect score guarantee a #1 ranking?
No. On-page targeting is one important factor, but rankings also depend on content quality, intent match, links and competition. This tool ensures the page is clearly optimized for your term — the rest is covered by off-page work and great content.
How is this different from a general page audit?
This tool grades a page against one specific keyword, while the On-Page SEO Audit reviews overall on-page health. Pair it with the Keyword Density Checker to inspect phrase frequency, and learn the fundamentals in our on-page SEO guide.
Is this a page keyword checker?
Yes. Enter a page and a target keyword and it works as an on-page keyword checker, scoring how well the term is placed in the title, H1, URL and body so you know exactly what to adjust.
