Technical SEO is the backbone of your website's search performance. Even the best content won't rank if search engines can't crawl or understand your site. I've fixed technical SEO issues for hundreds of sites→here's everything you need to know.
1. Site Speed and Core Web Vitals
Google uses page experience signals as ranking factors:
- LCP (Largest Contentful Paint): Under 2.5 seconds
- INP (Interaction to Next Paint): Under 200 milliseconds
- CLS (Cumulative Layout Shift): Under 0.1
2. XML Sitemap Optimization
- Create XML sitemap with all important pages
- Submit to Google Search Console
- Remove orphan pages and redirects
- Update automatically when content changes
3. Robots.txt Configuration
Your robots.txt file tells search engines what to crawl:
- Allow crawling of important content
- Block admin pages, thank-you pages
- Link to your XML sitemap
- Test with Google Search Console
4. URL Structure and Canonicalization
| Issue | Solution |
|---|---|
| Duplicate content | Use canonical tags |
| WWW vs non-WWW | 301 redirect to preferred version |
| HTTP vs HTTPS | Force HTTPS with redirects |
5. Structured Data (Schema Markup)
- Article schema for blog posts
- LocalBusiness schema for local businesses
- Product schema for e-commerce
- FAQ schema for FAQ sections
- Test with Google's Rich Results Test
6. Mobile-First Indexing
- Ensure mobile version has same content as desktop
- Check mobile usability in Search Console
- Ensure mobile page speed is fast
- Test with Google's Mobile-Friendly Test
7. Fix Crawl Errors
