What Is Technical SEO?

Technical SEO is the work that makes a website crawlable, indexable, and fast enough for Google to rank it. Before any content or keyword can help, Google has to be able to find your pages, understand them, and load them quickly for users. Technical SEO covers crawl errors, indexation, site speed and Core Web Vitals, mobile performance, site structure, schema markup, and duplicate content. It is the foundation the rest of SEO depends on, which is why I fix it first. Spending on content and backlinks while crawl errors and slow pages remain is like furnishing a house with no foundation. Get the technical base right, and every other bit of SEO effort afterward actually compounds.
