Technical SEO is the backbone of search engine success. While content and links matter, without proper technical implementation, search engines may not even index your site correctly. Here's what developers need to know.
Site Architecture and Crawlability
Search engines use bots (crawlers) to discover and understand your website. Your site architecture should allow these bots to easily access all important pages. This means:
- Clear URL structures
- Proper internal linking
- XML sitemaps that guide crawlers
- Robots.txt files that control crawler access
Page Speed and Core Web Vitals
Google has explicitly stated that page speed is a ranking factor. The Core Web Vitals metrics are:
- Largest Contentful Paint (LCP): How quickly the main content loads
- First Input Delay (FID): How responsive the page is to user interactions
- Cumulative Layout Shift (CLS): Visual stability during page loading
Optimizing these requires attention to JavaScript execution, image optimization, and careful CSS management.
Structured Data Markup
Structured data helps search engines understand your content better. Using schema.org markup, you can define:
- Article structure and publishing dates
- Product information and reviews
- Organization details
- Event information
- FAQ content
This markup enables rich snippets in search results, improving click-through rates.
Mobile Optimization
With mobile-first indexing, your mobile site is your primary site. Ensure:
- Mobile pages load quickly
- Text is readable without zooming
- Buttons and links are touch-friendly
- Viewport meta tags are properly configured
Canonicalization
When content exists on multiple URLs, use canonical tags to tell search engines which version is the primary one. This prevents duplicate content issues.
Implementation and Monitoring
Use tools like Google Search Console, Google PageSpeed Insights, and Lighthouse to monitor and optimize your technical SEO. Regular audits help identify issues before they impact rankings.
