Technical SEO

Technical SEO is the practice of optimizing a website's infrastructure so search engines can efficiently crawl, render, and index its content. It covers crawling, indexing, site architecture, page speed, mobile-friendliness, structured data, and server configuration. Technical SEO is a foundation — without it, content and links may not reach their potential.

Why it matters

Even the best content cannot rank if search engines cannot access, understand, or index it.
