What is On-Page SEO Analyzer?
Domain-level metrics tell you how strong a site is overall. On-page SEO tells you whether an individual page is set up to rank. Before you publish a landing page, audit a client site, or review a competitor's article, you want answers to simple questions: Is there a title tag? Is the meta description the right length? Is there one clear H1? Are Open Graph tags in place for social sharing?
This analyzer fetches the live HTML of any public URL and extracts the SEO elements search engines and social platforms read first. You get the title and description with character counts, heading structure, canonical URL, robots directives, and Open Graph metadata, plus a plain list of issues to fix.
It is not a full site crawl or Core Web Vitals report. It is the fast first pass every SEO does before opening a heavier tool, and it takes about five seconds.
How to Analyze a Page
- Paste the full page URL, e.g. https://yoursite.com/blog/post-title. https:// is optional.
- Click "Analyze Page" and wait while we fetch the live HTML.
- Review the issue list first, it highlights missing tags, long titles, multiple H1s, and noindex flags.
- Check the detailed tables for title length, meta description, headings, and Open Graph tags.
- Fix issues on your site, then re-run the check to confirm changes went live.

Frequently Asked Questions
Answers to what people usually ask about on-page seo analyzer.
Does this check my whole website?+
No, it analyzes one URL at a time. Run it on your homepage, key landing pages, and top blog posts individually. For a full-site audit you still need a crawler like Screaming Frog or Sitebulb.
Why can't it analyze some pages?+
Pages behind logins, blocked by firewalls, or that return non-HTML content (PDFs, APIs) cannot be analyzed. Some sites also block automated fetchers. If that happens, view the page source manually or use your browser's dev tools.
What title and description length should I aim for?+
There are no fixed limits, but Google typically shows about 50-60 characters of a title and 150-160 of a meta description before truncating. Our tool flags tags that are missing, short, or likely to get cut off.
Is word count accurate?+
It is an estimate based on visible body text after stripping scripts and styles. It is useful for spotting thin pages (under ~300 words) but not a substitute for a proper content audit.
