What Is Technical SEO?
Technical SEO focuses on the website infrastructure and signals that help search engines crawl, interpret and index pages effectively.
It includes areas such as site architecture, indexability, redirects, canonical URLs, XML sitemaps and performance. Technical improvements cannot compensate for content that fails to meet searchers' needs, but they can remove important obstacles.
Common Technical SEO Problems
| Problem | What to check |
|---|---|
| Pages not indexed | Review indexing reports, robots directives and page accessibility. |
| Broken links | Find internal links that lead to missing pages. |
| Redirect chains | Reduce unnecessary redirect hops. |
| Duplicate URLs | Review canonical tags, URL variants and duplicate content. |
| Slow loading | Investigate images, scripts, server responses and Core Web Vitals. |
| Missing sitemap | Check that the XML sitemap contains the intended canonical URLs. |
