About this on page seo checker free tool

Thin titles, missing meta descriptions, and multiple H1 tags quietly hurt rankings. Rankify's free on-page SEO checker audits a public URL or pasted HTML and reports title length, meta description quality, canonical and robots tags, Open Graph fields, H1/H2 structure, image alt coverage, and internal versus external links. You get a Google-style snippet preview, a 0–100 score, and a clear list of issues and warnings to fix before publishing. Fetch as desktop or smartphone to match crawler user agents, or paste View Source HTML when a site blocks remote fetches. No signup and no installs — built for bloggers, Indian agencies, SaaS founders, and marketers who need a fast HTML SEO check without enterprise crawl suites.

On-Page SEO Checker — Tool Options & Inputs

  • Input: Page URL or HTML

What this checker reviews

Title tag length and clarity, meta description length, canonical URL, and robots directives.

H1/H2 structure, Open Graph title/description/image, image alt coverage, and internal vs external link counts.

A 0–100 on-page score with prioritized issues and warnings you can copy as a report.

When to use URL vs HTML mode

Use URL mode for public pages your fetch proxy can reach — pick desktop or smartphone user agent.

Use HTML mode when the site blocks bots, requires login, or returns incomplete remote HTML: open View Source, paste, and audit locally.

Important Notes & Limitations

  • Audits a single HTML snapshot — not a full site crawl. Use View Source paste when remote fetch is blocked.
