Open Data Actors / free tools
Paste a page's HTML source and check title, description, headings, canonical, images, social tags and structured data in your browser.
Browsers block one site from fetching another, so open the page, press Ctrl+U (View Source), copy everything and paste it here. It checks what is in the HTML you paste. It cannot measure speed, rankings, backlinks, or content rendered by JavaScript after load.
To audit hundreds of URLs with the same checks plus status codes and redirects, technical-seo-page-audit on the Apify Store (details and free sample CSV) does it in bulk and returns structured data. Estimate the cost first with the pay-per-event cost calculator.
Disclosure: we build and maintain the Apify actors linked here. This page is free, has no tracking or analytics, and does not store anything; inputs stay in your browser except where the page says it calls a named public API.
