Let me break this down for you.
- Lazy-loaded Images: Lazy loading is a technique where images (or other content) are loaded only as they become visible in the viewport. This can speed up page loading times. But if not done right, search engines might not index these images, reducing opportunities for image search visibility.

Server-Side Rendering (SSR)
The advantage? Faster page loads and content that’s instantly accessible to search engines. The drawback, however, is a higher server load, which might impact performance if not managed properly.
Client-Side Rendering (CSR)
Each rendering method has its place, and the best choice often depends on your site’s specifics and the resources at your disposal. Regardless of the path you choose, the goal remains consistent: ensure that search engines can access, render, and index your content effectively.
- Avoid “Cloaking”: Ensure that both users and search engines see the same content. Any differences can be seen as deceptive and lead to penalties.
- Test, Test, Test: Use tools like Google’s Mobile-Friendly Test or URL Inspection Tool to see how Googlebot views your page. If there’s content missing, you might have a rendering issue.

- Lazy Loading with Caution: Lazy loading can improve performance but ensure that content above the fold isn’t lazy-loaded, so it’s immediately accessible to crawlers. Lazy loading iFrames works well for SEO too.
Despite best efforts, issues do pop up. The key is knowing how to diagnose and resolve them:

- Google Search Console: The URL Inspection Tool can show how Google views and renders your page.
- Google Lighthouse: Integrated into Chrome DevTools, Lighthouse provides insights on improving your web apps’ performance.
- Technical SEO audit: The agency will perform a technical SEO audit, provide an effective strategy, and offer other technical SEO consulting services for your digital needs.
Regularly test with tools like Google’s URL Inspection or Mobile-Friendly Test. Also, consider using server-side rendering for crucial content to ensure it’s in the initial HTML.
While no framework is inherently “SEO-friendly,” some, like Next.js and Nuxt.js, come with built-in server-side rendering, which can be beneficial for SEO.
Regularly monitor your organic traffic, keyword rankings, and indexation rates. Tools like Google Analytics and Search Console can offer valuable insights.
