What is a Good Time To First Byte?

Here's a benchmark to keep in mind: under 200 milliseconds (ms) for dynamic content, and tens of milliseconds (ms) for static content is considered ideal. This ensures a smooth user experience and sets the stage for other performance metrics like First Contentful Paint (FCP) to shine. 

‍

While the 200ms dynamic and 10s ms for static content mark is a great target, it's important to remember that website speed is a user-centric metric. What constitutes a "good" TTFB can vary slightly depending on factors like user location and network connection.

How to Test Your TTFB

‍

Several free and paid tools can help you measure your website's TTFB. Here are a few popular options:

‍

• Google PageSpeed Insights: This free tool by Google provides a wealth of insights into your website's performance, including TTFB.
• GTmetrix: Another free tool that offers detailed website performance reports, including TTFB measurement.
• Pingdom Website Speed Test: This free tool provides a quick and easy way to test your website's TTFB and other performance metrics.

‍

Once you have a time to first byte test tool in place, run a TTFB test on your website. The results will indicate your current TTFB in milliseconds.

The User-Centric Approach to TTFB

‍

Here's the thing: If your target audience spans the globe, a user in Sydney, Australia, will naturally experience a higher TTFB compared to someone in London due to sheer geographical distance from your server.

‍

But, Even within the same region, users can experience varying internet connection speeds due to network congestion or individual provider limitations. Someone on a slow connection might see a slightly longer TTFB than someone with high-speed fiber.

‍

So, how do we reconcile this? By aiming for a TTFB that feels snappy and responsive across a broad range of user locations and network conditions. Going for the ideal time is a great target, but even a slightly higher TTFB can be acceptable if users perceive the website as fast and responsive.

How to Improve TTFB

‍

Improving your TTFB revolves around minimizing server processing time and optimizing content delivery. Here are effective strategies to reduce TTFB:

‍

• Optimize Server Performance: Ensure your server is not overburdened. Upgrading your hosting plan or optimizing server configurations can lead to significant improvements in TTFB.
• Use a Content Delivery Network (CDN): CDNs cache your content on multiple servers around the world. This means users can download content from a server that's geographically closer, significantly improving TTFB and overall CDN performance metrics.
• Enable Caching: Implementing caching strategies can drastically reduce TTFB. By storing copies of files or data results, servers can quickly serve content without processing each request from scratch.
• Optimize Application Code: Streamline and optimize your website’s backend code. Efficient code reduces server processing time, directly improving TTFB.
• Database Optimization: Optimizing your database queries can significantly reduce response times, especially for dynamic content websites.

How to Find Your Niche's TTFB Sweet Spot

‍

There's no one-size-fits-all answer. We should simply aim for a first byte latency number that feels responsive and fast across a broad range of user locations and network conditions.

However, here are some methods to help you determine a good TTFB for your niche:

‍

• Competitor Analysis: Analyze the TTFB of your top competitors. This will give you a baseline for what users in your niche might expect. Tools like Google PageSpeed Insights or GTmetrix can help you measure their TTFB.
• User Testing: Conduct user testing sessions to gather feedback on perceived website performance. This can help you identify if your current TTFB is acceptable for a positive user experience.
