Technical SEO covers the optimizations of your site's infrastructure — crawlability, indexing, loading speed, HTTPS and data structure — that let Google find and understand your pages.
Technical SEO refers to infrastructure-level optimizations that let search engines access, understand and index your site correctly. It includes: loading speed (Core Web Vitals), HTTPS, mobile-friendliness, a correctly configured robots.txt, an XML sitemap, structured data (schema.org), canonicalization, avoiding duplicate content, hreflang for multilingual sites and crawl-budget management. Without a solid technical foundation, even the best content cannot rank.
Google cannot rank what it cannot access and understand. A wrong robots.txt can block the indexing of an entire site. Poor speed increases bounce rate and penalizes ranking. Core Web Vitals (LCP, INP, CLS) have been official ranking factors since 2021.

Core Web Vitals are 3 technical Google metrics — LCP, INP and CLS — that measure page user experience and have been official ranking factors since 2021.
Crawlability is the ability of Google's robots to access, navigate and read your site's pages — an essential prerequisite for indexing and ranking.
An XML sitemap is a file that lists all the important URLs of your site, helping Google discover and index them faster and more completely.
