You can write great content and build quality links, but if your site has technical problems, those efforts won’t reach their full potential. Technical SEO is about making sure search engines can crawl, understand, and index your site without obstacles.
Core Web Vitals
Google measures three metrics called Core Web Vitals: Largest Contentful Paint (how fast the main content loads), Interaction to Next Paint (how fast the page responds to clicks), and Cumulative Layout Shift (how much the page jumps around as it loads). Tools like Google Search Console and PageSpeed Insights will show you your scores and what to fix.
Mobile usability
Use Google’s mobile-friendly test to verify your site works on phones. Check that text is readable without zooming, buttons are large enough to tap, and content isn’t wider than the screen.
Crawlability
Check your robots.txt file to make sure you’re not accidentally blocking Googlebot from important pages. Use Google Search Console to see if any pages have been marked “noindex” unintentionally.
Site structure
Your most important pages should be accessible within two or three clicks from the homepage. If Google has to crawl five layers deep to find your service pages, they won’t be crawled as frequently — and they won’t rank as well.
Schema markup
LocalBusiness schema markup tells Google explicitly what your business name, address, phone, and hours are. It’s particularly important for local businesses and can influence how your listing appears in search results.
