Technical SEO

Technical SEO is the work of making sure search engines can crawl, index, and render a site cleanly, by tuning the infrastructure underneath the content. If your words and images are the furniture, technical SEO is the foundation and the wiring: without a solid base, even excellent content can stay invisible to Google. The everyday pieces are XML sitemaps, robots.txt rules, HTTPS, fixing broken redirects, and clean site architecture, with bigger sites also managing crawl budget so search engines don't waste time on low-value pages, and canonical tags so duplicate URLs don't compete with each other. Unlike on-page SEO, most of this needs developer access, which is why it's usually handled by whoever maintains the site.
