Free SEO checker

This free on-page SEO checker fetches your page and inspects the HTML signals search engines actually read when they decide how to rank it. It runs 16 checks across five categories, gives you a 0-100 score and an A-F grade, and - most importantly - hands you a prioritized list of fixes ranked by impact and effort so you know what to do first. Unlike most free checkers, it also scores your AI search readiness: whether ChatGPT, Perplexity, and Google AI Overviews can easily extract and cite your content. Free, no signup, no limits.

You can run a complete on-page audit of a page in under 20 minutes. Use the tool above for the scan, then work through these six steps:

1. Scan the page. Enter the URL to get your score and the 16-signal breakdown.
2. Fix the title and meta description. Title 30-60 characters with the keyword near the front; description 140-155 characters with a clear reason to click.
3. Get the headings right. Use exactly one H1 for the topic, then break the body into descriptive H2s and H3s.
4. Strengthen content and internal links. Fully answer the search intent and add contextual internal links to related and conversion pages.
5. Confirm technical signals. Verify HTTPS, a correct canonical, no accidental noindex, a lang attribute, and a responsive viewport.
6. Add schema and AI-readiness. Add JSON-LD and an FAQ section with concise answers so search engines and AI assistants can cite you.

On-page SEO is the part of search optimization you fully control. You can't make competitors stop building links, and you can't dictate Google's algorithm - but you can make every page unmistakably clear about what it offers and who it's for. That clarity is what earns rankings, clicks, and now AI citations.

Organic search drives the majority of trackable website traffic for most businesses, and the first organic result captures a far larger share of clicks than anything below it (Backlinko CTR study). A page that's missing a title, buries its H1, or accidentally ships a noindex tag simply can't compete - no matter how good the content is.

Two shifts make on-page work even more valuable now. First, mobile-first indexing means Google evaluates the mobile version of your page, so a missing viewport or unreadable layout is a ranking problem, not just a UX one. Second, AI Overviews and assistants increasingly answer questions by quoting well-structured pages. Pages with clear headings, concise answers, FAQ sections, and schema are the ones that get cited - a discipline sometimes called Answer Engine Optimization (AEO) or Generative Engine Optimization (GEO).

1. Title tag - the strongest on-page relevance signal and your headline in search results. See Google's title link guidance.
2. Meta description - doesn't directly rank you, but a compelling one lifts click-through rate.
3. H1 and heading structure - one clear H1 plus logical H2/H3s help both readers and extraction by AI.
4. Content depth - enough genuinely useful content to satisfy the search intent.
5. Image alt text - wins image search traffic and improves accessibility.
6. Internal links - spread authority and help crawlers find your other pages.
7. Canonical tag - prevents duplicate URLs from splitting your ranking signals.
8. Indexability - an accidental noindex is one of the most common and costly SEO mistakes.
9. HTTPS and mobile viewport - confirmed ranking and mobile-first indexing signals.
10. Structured data and AI readiness - JSON-LD schema and answer-led structure that earn rich results and AI citations.

80-100 (A/B): Strong on-page foundation. Focus on content depth, topical authority, and earning links to climb for competitive terms.

65-79 (C): Workable but leaking opportunities. Close the gaps in schema, internal linking, or meta tags first.

50-64 (D): Multiple ranking factors need attention. Start with title, indexability, and H1, then technical signals.

Below 50 (F): Core on-page elements are missing or broken. Fix the critical items (title, noindex, HTTPS, viewport) before anything else.

If you run SEO for clients, this tool is a fast way to scope work and qualify prospects. It's free with no usage limits, so you can audit as many pages as you need during sales calls, onboarding, or monthly reporting.

• Pre-fill a check by URL. Append ?url=example.com/page to this page to load a client's audit instantly, then copy the result link into a proposal or report.
• Lead with the priority fixes. The ranked fix list turns a raw audit into a clear, sellable action plan a client understands in seconds.
• Use the AI readiness check to start the conversation about AEO/GEO - a service most competitors aren't selling yet.

Need to audit hundreds of pages, build a white-label dashboard, or wire SEO data into your own reporting? That's exactly the kind of internal tooling we build - talk to our engineers.
