Indexing
noindex tags and headers, robots.txt, sitemaps, canonical URLs, and staging addresses left in the live site’s markup.
Links and redirects
Broken links, server errors, redirect chains, and old addresses from the previous site that no longer answer.
Tags and analytics
Page titles, meta descriptions, the mobile viewport, share images, and analytics on every page: Google, Plausible, Fathom, Matomo and more.
Security basics
HTTPS, the certificate and when it expires, files loaded over plain http, and HSTS.
SEO and speed notes
Duplicate titles, missing headings and alt text, slow or uncompressed pages, and sitemap pages nothing links to.
WordPress
Only when the site runs WordPress: usernames, author pages, xmlrpc.php, leftover install content and more.
