What is Technical SEO?
Turkish: Teknik SEO
Technical SEO improves site infrastructure so search engines can crawl, render, index, and evaluate pages quickly and reliably.
What is Technical SEO?
Technical SEO focuses on whether search engines can access a site, understand its pages, and index the right URLs before content quality is even evaluated. Crawlability, rendering, redirects, speed, and structured data all sit in this layer.
What Does It Cover?
A technical SEO review usually checks:
- Crawling: robots.txt, XML sitemaps, HTTP status codes, and broken links
- Indexing: canonical URLs, noindex rules, hreflang, and redirect chains
- Performance: server response time, image weight, JavaScript cost, and Core Web Vitals
- Security: HTTPS, mixed content warnings, and safe resource loading
- Structured data: product, article, organization, service, and breadcrumb markup
Business Use
A site with strong content can still lose visibility when technical issues block discovery. For example, faceted category filters may generate unlimited crawlable URLs, wasting crawl budget; an incorrect canonical tag may keep the preferred page out of the index.
In an SEO strategy, the technical layer is the foundation for content and authority work. E-commerce sites, multilingual corporate sites, and content-heavy portals should review it regularly.
