On-Page SEO Checker
An On-Page SEO Checker That Catches What "Has an H1" Checkers Miss
Paste a URL and get every on-page finding — title, meta description, heading hierarchy, image alt text, internal links, canonical tags — ranked by impact vs. effort, with no signup required.
What you get
Every on-page finding, ranked and fixable
Findings are ranked by impact vs. effort, each with a ready-to-use fix. See the full scoring methodology.
What "on-page" actually covers
Title, meta, headings, alt text, internal links, canonical
On-page SEO is everything on the page itself that's fully within your control: title tag, meta description, a single well-ordered H1 through H6 hierarchy (not just "does an H1 exist"), image alt text, internal linking, and canonical tags. It's checked alongside technical SEO, crawlability, and content quality in the same free run — because a perfect title tag rarely helps if the page is also blocked from indexing.
What this doesn't do
This runs the same full audit as the main SEO check — there is no stripped-down "on-page only" mode. It checks one page at a time, not a full-site crawl, and it measures what's structurally checkable; it can't guarantee a ranking.
FAQ
On-page SEO checker — FAQ
What counts as "on-page SEO" here? +
Everything that lives on the page itself and is fully within your control: title tag, meta description, heading hierarchy (H1 down to H6), image alt text, internal links, and canonical tags. It is distinct from technical SEO (crawlability, status codes) and off-page SEO (backlinks) — this page checks the on-page half specifically.
Does the checker run only on-page checks, or the full audit? +
One free check runs the full audit — technical, on-page, content quality, schema, and GEO readiness together — because a title-tag fix rarely helps if the page is also blocked from indexing. On-page is one weighted category in that SEO Health Score, not a separate limited mode.
Does it check heading hierarchy, not just whether an H1 exists? +
Yes. It checks for a single H1, a logical H2/H3 nesting order, and flags heading levels skipped or used out of order — a common on-page issue that a simple "has an H1" checker misses.
Does it check image alt text and internal linking? +
Yes, both are part of the on-page category: missing or empty alt attributes on meaningful images, and whether the page links internally to related content in a way that helps both users and crawlers.
Is the on-page SEO checker free? +
Yes — paste a URL and get a ranked list of on-page findings, plus the rest of the SEO Health Score, with no signup.
