Technical SEO: Speed, Indexing, Sitemaps and Robots
Опубликовано: 2026-03-31 21:00:38
Search engines have two main goals: understand and deliver content. Technical SEO is about helping them do that. This article covers three core aspects: page loading speed, indexing, and sitemaps.
1. Page loading speed
Page loading speed is a ranking factor. A fast site is more attractive to users and search engines. Users expect instant gratification and leave slow sites. Search engines consider bounce rates, time-to-first-byte, and time-to-interactive. Google’s PageSpeed Insights diagnoses issues and offers fixes. Use a content delivery network (CDN), compress images, minify CSS, JS, and HTML, and enable browser caching. Use a performance budget.
2. Robots.txt
A robots.txt file lets search engines know which pages to crawl. Use Google Search Console to test and submit sitemaps. Put it in the root, and disallow search engine spam. Avoid blocking important pages, and test with Google’s robots.txt tester.
3. Sitemaps
A sitemap is a list of pages. Use an XML sitemap and HTML sitemap. Submit it in Search Console. Add a sitemap link in robots.txt and footer. Use a logical structure. Put it in the robots.txt, and make it search engine friendly.
4. Canonicalization
Choose the best URL. Use the rel=canonical tag or 301 redirects. Avoid duplicate content and self-cannibalization. Use the preferred domain.
5. HTTPS
HTTPS encrypts communication and authenticates users. Google prefers it. Use Let’s Encrypt or an SSL certificate. Install it via your registrar or hosting.
6. Redirects
Use 301 redirects for old URLs. Fix broken links and redirect pages to relevant ones. Use meta refreshes for temporary redirects.
7. Mobile optimization
Use a responsive design, mobile-friendly design, and a viewport tag. Use the Google Mobile-Friendly Test.
8. Structured data
Use JSON-LD schema markup for rich snippets. Google Search Console shows errors. Use structured data testing tools.
9. Robots meta tag
Use noindex for low-quality pages, duplicate content, and search results snippets. Use nofollow for unimportant pages.
10. Analytics
Use Google Analytics and Search Console. Monitor traffic, impressions, CTR, and positions. Use Google Tag Manager for tracking.
11. Robots meta tag
Use index, noindex, and nofollow. Avoid robots.txt blocking. Use Google Search Console to find blocked pages.
12. HTTP status codes
Check HTTP status codes. Use the Chrome DevTools Network tab. Fix server errors and 404s.
Conclusion
Technical SEO improves search engine rankings and user experience. Prioritize speed, indexing, sitemaps, and mobile. Use HTTPS, redirects, and structured data. Use robots, analytics, and HTTP status codes.
