AIO SEO Checkerとは
Free SEO checker for any page: meta tags, headings, broken links, schema, redirects, Core Web Vitals and AI crawler access. The free SEO checker that sits beside the page you're on. Open the side panel on any website and see every SEO and AI search check at once: meta tags, headings, links, images, structured data, redirects, page speed, and whether AI assistants can read the page. The worst problem comes first, with the fix to paste.
No account. No API key. Nothing leaves your browser.
WHAT IT CHECKS
Meta tags
- Title and meta description with Google's pixel cut-off, character count and a live search result preview for desktop and mobile
- Canonical, robots directives, viewport, language and character set
- Social sharing tags, with a preview of how the page looks when shared
- Every other meta tag on the page, each one copyable
Headings
ストアの説明の続きを表示▾
- The full heading outline, with skipped levels and empty headings flagged
- Show heading levels right on the page, copy the outline or export to CSV
Links
- Internal, external and nofollow links
- Broken link checker: finds dead links and redirects in seconds
- Highlight nofollow links on the page and export to CSV
Images
- Missing alt text, missing dimensions, oversized images and a slow-loading main image
- Show alt text on the page and export to CSV
Structured data
- Every structured data item on the page, with the raw code
- Whether each one qualifies for a Google rich result, and what is missing
- Generate ready-to-paste markup for the types a page like yours needs
AI search
- Which AI crawlers your robots.txt allows or blocks, and the exact lines to unblock them for this page
- Whether your content is in the page's HTML or only appears after JavaScript runs, which most AI crawlers never see
- Settings that stop search engines quoting your page in AI answers
- Which sections of the page an AI answer could quote on their own
Technical SEO
- HTTP status and the full redirect chain of the page you loaded
- Indexability: noindex, robots.txt, canonical target and sitemap
- Language targeting, response headers and HTTPS
- Core Web Vitals measured from your own page load
- The platform and tools the site is built with
Compare with a competitor
- Paste any URL and see which checks they pass that your page fails, side by side
Every issue explains why it matters and, where there is one, gives a paste-ready fix. Export the whole audit as a report for a ticket or a client.
HOW TO USE Click the toolbar icon or press Alt+Shift+A. The panel opens beside the page and updates as you browse.
PRIVACY Everything runs in your browser. The extension reads the page you are on and fetches that site's own robots.txt, sitemap and HTML to check them. Every request it makes is listed in Settings. No account, no analytics, nothing sent to us or anyone else.
