Free SEO Scanner
An SEO scanner fetches your site the way a search crawler does and reports what would stop it being found, indexed or ranked. Paste your URL and CheckVibe checks crawling and indexing, on-page metadata, content, internal links and speed across up to eight pages.
No account, no signup — the full report shows right here
No source code and no account: the score, every check and the fix for each one render on this page. The AEO scanner is the sibling tool for AI visibility, and runs in the same pass.
Five areas, weighted the way they cost you traffic
Most SEO problems are not subtle. A stray noindex shipped to production, a sitemap listing pages that redirect, a single-page app that serves an empty shell to a crawler — each one is invisible to a human visitor and decisive to a search engine. Google's crawler documentation describes the same fundamentals this scan verifies.
robots.txt, sitemap, canonicals, noindex directives and redirect chains
Titles, descriptions, heading structure, Open Graph and structured data
Thin or duplicated pages, and whether the text exists without JavaScript
Internal linking depth, broken links and what the anchor text actually says
The field speed metrics search engines measure and rank on
The AEO scanner is the sibling tool: can ChatGPT and Perplexity cite you?
Three steps. One pasted URL.
- 01
Paste your URL
No install, no config, no repository access. CheckVibe fetches your deployed site the way a search crawler does.
- 02
Five areas, eight pages
Crawling and indexing, on-page metadata, content, links and speed — sampled across your site, not just the homepage.
- 03
Fix with AI
Every finding ships as a copy-paste prompt for Claude, Cursor and Windsurf, so a missing canonical is one paste away from fixed.
Frequently asked questions
- What is an SEO scanner?
- An SEO scanner fetches your pages the way a search engine crawler does and reports what would stop them being found, indexed or ranked. It reads robots.txt, your sitemap, canonical tags and meta robots directives, then checks the markup of the pages themselves — titles, descriptions, headings, images, internal links — and the speed signals search engines measure.
- What does the CheckVibe SEO scanner check?
- Five areas, weighted the way they affect ranking: crawling and indexing (robots.txt, sitemap, canonicals, noindex, redirect chains), on-page metadata (titles, descriptions, headings, Open Graph, structured data), content (thin or duplicated pages, heading order, readable text without JavaScript), links (internal linking, broken links, anchor text) and performance (the field metrics search engines use). It samples up to eight pages, not just the homepage.
- Is the SEO scanner free?
- Yes. Paste a URL and the scan runs with no install and no signup. A free account keeps the result and tracks what changed between runs; paid plans add copy-paste AI fix prompts and continuous monitoring.
- Does it work on a JavaScript app?
- It runs against the HTML your server actually returns, which is exactly what a crawler sees first. On a client-rendered app that is often close to empty — and the scan says so explicitly rather than scoring the shell as if it were the page. That result is usually the single most valuable thing it tells a single-page app.
- What's the difference between SEO and AEO?
- SEO optimizes for a ranked link on a results page; AEO optimizes for being cited inside a composed AI answer. They share their foundations — if a crawler cannot reach or read you, neither works — but AEO adds failure modes of its own, like a WAF that blocks GPTBot specifically. The AEO scanner is the sibling tool to this one.
- Is this the same scan the dashboard runs?
- It is the same scanner. SEO is a free tool rather than part of a paid scan: a signed-in CheckVibe scan covers security and your domain — DNS, certificates, speed, privacy and accessibility — and re-measuring meta descriptions on every scheduled audit was not what that scan is for.
