What Does the SEO Checker Do?
Paste any public page URL and this tool fetches it on our server, then checks it against the same on-page signals search engines look at: title and meta description length, a single clear H1, mobile viewport and HTTPS, canonical tags, image alt text, structured data (JSON-LD), and Open Graph/Twitter social tags. Each check comes back as Pass, Warning, or Fail with a plain-language explanation, plus an overall score out of 100 — no account, no crawling limits, no vague "grade" with no detail behind it.
How to Check a Page's SEO — Step by Step
- Paste a URL. Enter any public page address, e.g. example.com/blog/post.
- Run the check. Click "Check SEO" — the page is fetched and analyzed in a few seconds.
- Read the results. Work through each Warning or Fail, grouped by Meta Tags, Content, Technical, Structured Data and Social.

Frequently Asked Questions
Can I check a page that isn't live yet, like localhost?▾
No — for security reasons this tool only fetches public, internet-reachable URLs. Local, private-network and internal addresses are blocked.
Does a high score guarantee good rankings?▾
No. This checks on-page technical and content signals only — it can't measure backlinks, domain authority, content quality relative to competitors, or user engagement, all of which also affect rankings.
Why does it say a check "couldn't be verified"?▾
A small number of pages use non-standard HTML that our lightweight analyzer can't reliably parse. When that happens, the check is marked as a warning rather than guessed at.
Is my URL or the page content stored?▾
No. The page is fetched, analyzed in memory, and the result is returned to you — nothing is saved on our servers.
