Sander Vermeer — technical SEO for JavaScript-heavy sites

**Navigating Technical SEO for JavaScript-heavy Sites** JavaScript can enhance user experience, but it poses unique challenges for SEO. The primary insight? Ensure your content is crawlable. Search engines often struggle with dynamic content rendered client-side. To mitigate this: 1. **Server-Side Rendering (SSR)**: Consider implementing SSR to deliver HTML content to crawlers, improving indexing. 2. **Prerendering**: For less frequently updated pages, prerendering can serve static HTML snapshots, ensuring visibility. 3. **Use Structured Data**: Implement schema markup to provide context about your content, helping search engines understand your offerings better. Regularly test your site with tools like Google Search Console and Lighthouse to identify and fix potential issues. Prioritizing these strategies will keep your JavaScript-heavy site competitive in search rankings.
