Technical SEO is the work of making sure search engines can find, read and store a site's pages. It covers crawling, rendering, indexing, redirects, canonical tags, server responses and site speed. It is mostly the plumbing of a site, and it does not replace having something worth finding.
Beginners might begin with Google's guide to the Page Indexing report, from Google's own staff, or Won't somebody think of the robots?, a 2019 talk pitched at business owners. Developers may prefer Technical SEO for JS Web Apps. Readers who work with server logs can try When Server Logs Lie. Sources include Google, conference organisers and software companies, so some videos show their own tools. Plenty date from 2022 or earlier, and a few go back to 2014, so treat those as background reading.
