SEO & Web

SEO Checker — Free Website Audit

Paste a URL to get an SEO score from 30 checks across on-page, technical, social, performance and accessibility — with a plain-English fix for every issue.

Paste any public page — your homepage, a blog post or a Fiverr/Upwork portfolio site. We check the HTML the server sends, plus its robots.txt and sitemap.

  • 30 checks, one score

    Every check has a fixed weight, so the score is consistent and you can see exactly what moved it.

  • Fixes you can apply

    Each issue explains why it matters and what to change — ready to hand to a developer or fix yourself.

  • Search & social previews

    See roughly how the page looks in Google results and when shared on WhatsApp, Facebook, LinkedIn and X.

Free online SEO checker

Enter any public URL and the checker downloads the page the way a search engine crawler first sees it, then reviews the HTML, its robots.txt and its XML sitemap. You get an overall score out of 100, a score for each category and a list of issues sorted by impact. Export the full result as JSON or print it / save it as a PDF for a client.

What it checks

  • On-page: title length and duplicates, meta description, a single clear H1, heading order, word count and most-used words.
  • Technical: HTTP status, HTTPS, redirect chain, noindex/nofollow in meta robots and the X-Robots-Tag header, canonical URL, mobile viewport, character encoding, robots.txt rules, sitemap, JSON-LD structured data and favicon.
  • Social: Open Graph tags (og:title, og:description, og:image, og:url, og:type) and the Twitter/X card.
  • Performance basics: server response time, HTML size, compression and render-blocking scripts in the page head.
  • Accessibility basics: page language, images without alt text, links without text and disabled pinch-to-zoom.

How to use it

  1. Paste the page address (with or without https://) and press Audit page.
  2. Start with the critical issues, then warnings — each one has a “How to fix” note.
  3. Re-run the audit after your changes to confirm the score went up.

Good to know

  • The checker reads the HTML your server sends and doesn't run JavaScript, so content that only appears after scripts run isn't counted.
  • For Core Web Vitals (LCP, CLS, INP), use the Google PageSpeed Insights link in your results — it tests the page in a real browser.
  • Response time is measured from our server, so it can differ from what visitors in your city see. Some sites block automated requests; if so, the audit reflects the page they returned.

How this works. This tool runs on AISeekho's server because a browser can't do it on its own. We don't store what you enter.
