Definition

What is Technical SEO?

Technical SEO is the work of making a website easy for search engines and AI crawlers to access, understand and index: crawlability, indexation, site speed and Core Web Vitals, mobile rendering, structured data, canonical URLs and clean site architecture. It is the foundation content ranks on.

Why it comes first

Publishing into a site that can’t be crawled, renders slowly or indexes wrongly wastes every article. That is why a serious program starts with an audit and fixes — and only then scales content.

The AI-crawler angle

AI systems add new requirements: pages must render without heavy client-side work, robots.txt must welcome AI crawlers you want, and llms.txt gives them a map. Technical SEO now serves two kinds of machine readers.
