Technical SEO Guide for Beginners: Everything You Need to Know

Technical SEO is the foundation everything else builds on. If Google can't crawl and index your site properly, no amount of content or backlinks will help. Here's what matters.

Crawling: Can Google Find Your Pages?

Google discovers pages by following links and reading your sitemap. Make sure you have: a valid XML sitemap submitted to Search Console, a robots.txt that doesn't accidentally block important pages, and a clean internal linking structure where every page is reachable within 3 clicks from the homepage.

Indexing: Does Google Store Your Pages?

Check the "Pages" report in Search Console. Common issues: pages blocked by robots.txt, noindex tags on important pages, duplicate content causing Google to pick the wrong version, and thin content that Google deems not worth indexing.

Site Speed: Core Web Vitals

Google measures three things: LCP (how fast the main content loads, target under 2.5s), INP (how fast the page responds to interactions, target under 200ms), and CLS (how much the layout shifts during loading, target under 0.1).

HTTPS: Non-Negotiable

If your site isn't on HTTPS, fix this today. It's a confirmed ranking factor, browsers show "Not Secure" warnings, and users don't trust HTTP sites.

Mobile-First: Your Mobile Site IS Your Site

Google indexes the mobile version of your site. If your mobile experience is bad, your rankings suffer regardless of how good the desktop version looks.
