JavaScript SEO Best Practices for Modern Frameworks
JavaScript SEO focuses on ensuring search engines can crawl and render dynamically generated content. Use Server-Side Rendering (SSR) or Static Site Generation (SSG) whenever possible, ensure links use proper <a> tags with href attributes, and provide unique URLs for all content views.
Search engines have gotten better at rendering JavaScript, but it's still more resource-heavy and slower than crawling HTML. If your site relies on React, Vue, or Angular, you risk 'partial indexing' where Google sees an empty shell before the JS executes. To avoid this, technical SEOs should prioritize SSR. pSeoMatic bridges this gap by focusing on high-performance HTML generation. By delivering pre-rendered content, pSeoMatic ensures that search engines see your full content instantly, eliminating the 'second wave of indexing' delays associated with heavy JS sites.
Stap-voor-stap gids
Use SSR or SSG
Render your JavaScript on the server or during the build process so the initial HTML payload sent to the browser contains all the important content.
Check the Rendered HTML
Use the URL Inspection tool in Search Console to see the 'View Rendered Page' screenshot. If the content is missing, Googlebot isn't seeing it.
Avoid Hash-Based Navigation
Never use '#' in your URLs for navigation (e.g., site.com/#/page). Use the History API to create clean, crawlable URLs that Google can index.
Optimize Link Discovery
Ensure your internal links are standard HTML <a> tags. Avoid using JS 'onClick' events for navigation, as crawlers may not follow them.
Pro Tips
- Don't block your JS files in robots.txt; Google needs them to render the page.
- Set a reasonable timeout for your scripts; if they take too long, Googlebot may give up.
- Implement 'Dynamic Rendering' as a workaround if you cannot change your core architecture.
