什麼是 Technical SEO Optimization

Technical SEO is the practice of optimizing a website's infrastructure so search engines can crawl, index, and rank it effectively. It covers site speed, mobile optimization, URL structure, structured data, XML sitemaps, robots.txt, and crawl efficiency. Technical SEO is distinct from content strategy and link building; it's the foundation those strategies stand on. A technically sound site can rank despite weaker content; a technically broken site won't rank regardless of content quality. Google's Core Web Vitals algorithm now weighs user experience metrics (loading, interactivity, stability) in rankings, making technical SEO directly tied to business results.

❓ 常見問題

What are Core Web Vitals and why do they matter?
Core Web Vitals are three metrics: Largest Contentful Paint (LCP, loading speed), First Input Delay (FID, interactivity), and Cumulative Layout Shift (CLS, visual stability). Google ranks pages partly on these metrics. Optimizing them improves both SEO and user experience.
How does mobile-first indexing affect SEO?
Google now primarily crawls and indexes the mobile version of sites. If your mobile site is slower or has missing content, ranking suffers. Test mobile experience in Search Console and fix issues there first.
What's structured data and how does it help SEO?
Structured data (JSON-LD, microdata) tells Google what content is on your page (reviews, recipes, products). It can enable rich snippets in search results, increasing click-through rates and authority.
Should I use a static site or dynamic rendering for SEO?
Static HTML is fastest and most crawlable. If you use JavaScript, ensure Googlebot can render and index your content. Use tools like Lighthouse to verify.
How do I fix crawl errors in Search Console?
Common errors: 404 (missing pages), redirect chains, server errors (5xx). Prioritize fixing pages that get traffic. Use Search Console to see which URLs are problematic.
