How to use On-Page SEO Checker
This on-page SEO checker fetches any public URL and grades its on-page signals — title and meta length, heading structure, image alt text, canonical, mobile viewport, Open Graph, structured data, indexability and more — into a single score with a prioritized list of what to fix first. Deterministic, free, no sign-up.

Private by design
Runs in your browser — your files never leave your device.
Fast & simple
A clean interface, instant results, and it works on any device.
Audit a page before you publish
Run a new page through the checker before it goes live to catch the easy misses — a missing meta description, two H1s, images without alt text, no Open Graph tags. Fixing them up front means the page launches in good shape instead of needing a cleanup pass weeks later once it is already indexed.
Diagnose why a page is not ranking
When a page underperforms, on-page issues are often the cheapest fix. The audit flags thin content, a noindex you forgot, a missing canonical or a weak title, each with a short explanation, so you can rule out the basics before reaching for harder, slower levers like link building.
Spot-check a client or competitor page
Get a fast, objective read on any URL without logging into a heavyweight suite. The score and check list give you talking points for an audit or a quick sense of how a competitor has set up their highest-ranking pages.
On-Page SEO Checker — frequently asked questions
What does the SEO score mean?
It is a weighted roll-up of the on-page checks — important factors like title, indexability and viewport count for more than minor ones. Treat it as a quick health indicator and focus on the specific red and amber items rather than chasing a perfect 100.
Does it check off-page factors like backlinks?
No. This tool audits on-page signals you control on the page itself. Backlinks, domain authority and rankings are off-page and need different tools.
Is my data stored?
No. The page is fetched live each time and graded on the fly. Nothing about the URL or its content is saved.
