Sitemap URL Extractor & XML Sitemap Checker

somepineapple/sitemap-extractor-checker-tool

Find broken links and images on any website. Reads the site's pages, checks every link and image on them, and lists each broken one (404, server error, dead domain, timeout) with the pages it appears on. Also flags redirects and links that sites refuse to check.

Audit web pages for on-page SEO in bulk: title and meta description length, headings, canonical, noindex, mobile viewport, image alt text, links, word count, Open Graph, schema.org, HTTPS and speed. Each page gets a 0-100 score and a plain list of issues to fix.

Check titles, meta descriptions, canonical, noindex, Open Graph, H1, hreflang and JSON-LD for many URLs, with issue flags and a score.
