Technical SEO
Optimising a site's infrastructure (crawlability, indexation, speed, structured data, architecture) so search engines can find, understand, and rank it.
Technical SEO is the foundation layer of search: the work that lets crawlers reach your pages, understand what they are about, and serve them quickly. It sits beneath content and links. You can have both, but if the technical base is broken, neither performs.
In practice it covers crawlability and indexation (clean sitemaps, sensible robots rules, canonical tags), site speed and Core Web Vitals, structured data so pages are eligible for rich results, a logical internal-linking architecture, and the handling of redirects, duplicate content, and mobile rendering.
Unlike content, technical SEO is largely a one-time investment plus maintenance. Fix the architecture once and every page benefits. That compounding quality is why we treat it as the first thing to get right on any build or migration, not a clean-up task bolted on at the end.
