Technical SEO

Meaning

Technical SEO is the work on a website's infrastructure so it can be crawled, indexed and used smoothly, including speed, mobile friendliness, security and indexing controls. It is the wiring and plumbing under your content: good articles still struggle if the site blocks crawlers, loads very slowly or shows errors. Start with robots.txt, the XML sitemap, HTTPS, status codes, canonical tags and Core Web Vitals, and review them on a schedule and after any major change.
