# Technical SEO Guides

Improve crawlability, indexing, rendering, and technical signals that support organic visibility.

- [Crawl Budget](/en/guides/crawl-budget.md): Understand crawl budget, crawl capacity, crawl demand, robots.txt, sitemaps, redirects, duplicate URLs, and the fixes that help search engines focus on valuable pages.

- [Log File Analysis](/en/guides/seo-log-analysis.md): Use server and edge logs to see how search crawlers really access your site, uncover wasted crawl activity, and connect SEO problems to infrastructure events.

- [Core Web Vitals Guide](/en/guides/core-web-vitals.md): Understand LCP, INP, and CLS, their current good thresholds, how to measure them in field and lab data, and which fixes to apply first.

- [Redirects, Caching, and SEO](/en/guides/redirects-caching-seo.md): Redirect chains, cached responses, and inconsistent canonical signals can slow users and complicate crawling. Learn how to design and measure them safely.

- [HTTP Status Codes and SEO](/en/guides/http-status-codes-seo.md): A practical guide to 2xx, 3xx, 4xx, and 5xx responses: how status codes affect crawling, indexing, redirects, caching, and web performance.

- [Technical SEO Infrastructure](/en/guides/technical-seo-fast-websites.md): A technical SEO checklist for edge infrastructure: DNS, HTTPS, redirects, caching, response time, Core Web Vitals, crawlability, and validation.

- [GEO vs SEO](/en/guides/geo-vs-seo.md): GEO is not a replacement for SEO. Learn how crawlability, clear content, links, structured data, and measurement support visibility in AI search experiences.

- [Hreflang and CDN Routing](/en/guides/hreflang-cdn-routing.md): How to combine hreflang with predictable CDN routing so search engines discover the right locale and users receive fast, correct content.

- [JavaScript Rendering and SEO](/en/guides/javascript-rendering-seo.md): A fast browser experience is not proof that crawlers can index your content. Learn how JavaScript rendering fails and how to test the full crawl path.

- [SEO Site Migration](/en/guides/seo-site-migration.md): Plan an SEO site migration with URL mapping, permanent redirects, canonicals, hreflang, sitemaps, rendering checks, monitoring, and rollback controls.
