Grade Your On-Page SEO in Seconds
Enter any URL to instantly check its meta tags, headings, content length, and image attributes. Find out exactly why your page isn't ranking.
GazeSEO's free website crawler checks your technical SEO, content optimization, and link structure against the latest search engine guidelines to help you boost organic traffic.
How to Check Your SEO
Three steps from a URL to a clear, actionable audit.
Paste your page URL
Enter any page. We fetch its live HTML, just like a search engine crawler, and read every on-page signal that matters for ranking.
Review your score and issues
We grade the page across meta, content, structure, links, and server config, then group the results into passes, warnings, and issues.
Fix and re-run
Each issue comes with a plain-language fix. Make the change, analyze the URL again, and watch your score climb.
What Is an SEO Checker?
An SEO checker is a tool that fetches a web page and inspects the on-page signals search engines use to understand and rank it. That includes your title tag, meta description, heading structure, image alt text, canonical URL, Open Graph tags, internal and external links, and server configuration.
Instead of digging through your page source by hand, an SEO checker reads the live HTML the way Googlebot does and reports exactly what is present, what is missing, and what falls outside best-practice ranges, like a title that is too long or a meta description that is too short.
Any site owner, marketer, or developer who wants pages that rank in Google and surface in AI answers should run an SEO check before and after publishing. It takes seconds with this free tool, requires no plugins, and needs no sign-up.
Why run an on-page SEO check
A few seconds of analysis catches issues that quietly cost you rankings and clicks.
Catch ranking blockers early
A stray noindex tag or missing title can keep a page out of search entirely. Find these before they cost you traffic.
Win more clicks from search
Well-sized titles and descriptions control how your snippet looks in results, which directly drives your click-through rate.
Look great when shared
Open Graph tags decide how your links appear on social and in chat apps. Get rich previews instead of bare URLs.
Be ready for AI search
Clean structure and clear headings help AI engines like ChatGPT and Perplexity understand and cite your content correctly.
On-page vs technical vs off-page SEO
Three layers of SEO that work together. This tool focuses on the first two.
Titles, descriptions, headings, and content quality on the page itself. The fastest wins, and what this checker grades.
HTTPS, canonical tags, indexability, and server response time. We surface these on-page technical signals here too.
Backlinks, mentions, and reputation earned across the web. Important, but separate from what lives on your page.
What This SEO Checker Analyzes
Every check maps to a signal search engines and AI crawlers actually use, grouped into five areas.
- Meta information: title and description length, canonical, robots, and language.
- Page quality: content word count, image alt coverage, favicon, and Open Graph.
- Page structure: a single H1, plus supporting H2 and H3 headings.
- Link structure: internal links for architecture and external links for authority.
- Server configuration: HTTPS security and server response time (TTFB).
- Indexability, so a stray noindex never goes unnoticed.
✓ Title tag 54 chars — optimal ✓ Meta description 148 chars — optimal ⚠ H1 heading 2 found — use one ✓ Canonical URL present ✓ HTTPS secure ⚠ Open Graph incomplete ✓ Word count 1,240 words ✓ Server response 180 ms Score: 88 / 100
Does On-Page SEO Still Matter in the AI Era?
On-page signals now feed both classic search and the new generative layer.
It is the foundation of ranking
Titles, headings, and content quality are still core inputs to how Google ranks pages. Get these right and everything else compounds on top.
AI engines read the same signals
Assistants like ChatGPT, Perplexity, and Claude parse your title, structure, and content to understand and cite your page. Clean on-page SEO is now GEO too.
Fastest wins in SEO
On-page fixes are fully in your control and ship in minutes, unlike backlinks. A quick audit often surfaces changes that move rankings the same week.
How Your SEO Score Is Calculated
Your page starts at a perfect 100, and we subtract points for each issue we find, weighted by how much it actually matters. A missing title, a noindex directive, or no HTTPS costs far more than a missing favicon. Warnings cost a few points each; bigger issues cost more. The result is a single score from 0 to 100 that reflects the real impact of what is wrong, so you know exactly where to focus first.
