Remar SEO Rendered Page Audit adds an “Audit this page” button to the admin bar. Click it on any front end page and a panel lists what is right and what needs fixing, with a score.

Checks include:

Title tag and meta description length
Canonical tag, robots noindex, lang, viewport, hreflang
H1 count, skipped heading levels, full heading outline
Word count, images missing alt text or dimensions
Internal, external and nofollow links, links with no accessible text
Open Graph and Twitter card tags
JSON-LD structured data types and parse errors
HTTPS, mixed content, duplicate IDs

You can also click “Audit” in the Posts or Pages list to open a published page with the audit already running.

All checks run in your browser on the rendered page. The plugin sends no data anywhere, stores nothing in the database, and loads no external code. Only logged in users who can edit posts see the button or load the assets. Every feature is free.

Full site audits

This plugin audits one page at a time, and every feature in it is free. If you need site-wide crawls, scheduled reports or historical tracking, the separate SiteAuditLint service by the same author offers those at siteauditlint.com. The plugin works fully without it and never sends data there.
