How Can I Improve Server Response Time (TTFB) and Page Speed to Increase the Likelihood of Pages Marked as "Discovered - Currently Not Indexed" Getting Indexed?

Summary

Improving server response time (TTFB) and page speed can increase the chances of your pages getting indexed by search engines. This can be achieved by optimizing server performance, implementing efficient content delivery, reducing render-blocking resources, and enabling build-time optimization. Detailed steps are provided below.

Optimizing Server Performance

Server Hardware and Software Upgrades

Upgrading the server's hardware, improving internet connection speed, and updating server-side software can enhance server's response time [Reduce Page Weight, GTMetrix].

Server Configuration

Take advantage of server configuration practices such as Gzip compression and keep-alive connections to speed up server response time [Leverage Browser Caching, Varvy].

Database Optimization

Optimize the database by indexing, using stored procedures, and limiting query results to speed up the server [Improving Indexing For Increased Page Speed And SEO, Dev.to].

Implementing Efficient Content Delivery

Content Delivery Network (CDN)

CDNs deliver web content to users based on their geographic locations, speeding up the delivery process. User web servers get the requested content from the nearest CDN server [Why Use A CDN? A Comprehensive Guide, CDNify]

.

Resource Minification

Minification reduces the size of code files and removes unnecessary characters, thus improving loading speed [Reduce Network Payloads Using Text Compression, web.dev].

Image Optimization

Compress and optimize images without compromising on their quality, this helps in improving page speed and server response time [Optimize Encoding and Transfer, Google Developers].

Reducing Render-Blocking Resources

Deferring Unused CSS/JS

Deferring non-critical CSS and JavaScript helps in improving server response time by delaying the loading of these resources until critical resources have finished loading [Defer Non-Critical CSS, web.dev].

Inline Critical CSS/JS

Inlining critical CSS and JavaScript directly into HTML can speed up rendering by reducing the number of requests to the server [Reducing LCP to Improve SEO, IoT for All].

Enable Build-Time Optimizations

Lazy Load Non-Critical Assets

Lazy-loading defers the loading of non-critical resources until they're needed, improving initial page load time [Lazy Load Images and Video, web.dev].

Server Pre-Rendering

Pre-rendering generates HTML in advance for each page of your site, this makes your site faster and can help improve your SEO [Prerender, Prerender.io].

Conclusion

Improving server response time and page speed for "Discovered - currently not indexed" pages involves server optimization, efficient content delivery, reducing render-blocking resources, and enabling build-time optimization. Implement these strategies to increase the possibility of your pages being indexed.
