In today’s digital age, where every aspect of our lives is driven by technology, website speed is paramount. Unfortunately, people have become accustomed to instant gratification, and if a website takes too long to load, they will leave and find an alternative. This is where Time to First Byte (TTFB) comes into play.
TTFB refers to the time it takes for a web server to respond to a request from a user’s browser. It is the first step in loading a web page, and it plays a crucial role in determining a website’s overall speed and performance.
In this article, we’ll explore the impact of TTFB on user experience and SEO and provide tips on improving your website’s TTFB.
What is Time to First Byte?
TTFB is the time it takes for a web server to respond to a request from a user’s browser. It is the time between the user’s request for a web page and the server’s first response. TTFB is often confused with page load time, but they are different. Page load time refers to the time it takes for a web page to load fully, including all the content, images, and scripts. TTFB, on the other hand, only measures the time it takes for the server to send data back to the browser.
In simpler terms, TTFB is the time it takes for the server to say “hello” to the browser. It is affected by various factors, including server location, server load, network latency, and caching.
Why is TTFB important for user experience?
TTFB is an essential factor in determining a website’s overall speed and performance. It is a user’s first impression of a website, and it sets the tone for the rest of their experience. If a website has a slow TTFB, it will take longer for the user to see any content, and they may become frustrated and leave before the page has fully loaded. This can lead to a poor user experience and, ultimately, a loss of traffic and revenue.
Studies have shown that a delay of just a few seconds in TTFB can significantly drop user engagement and conversions. For example, according to Google, a delay of 100ms in TTFB can result in a 7% reduction in conversions. This highlights the importance of TTFB in delivering an exceptional user experience.
How TTFB affects SEO?
TTFB also plays a crucial role in determining a website’s SEO rankings. Google has stated that website speed is a ranking factor, and TTFB is a critical component of website speed. A slow TTFB can result in a lower search engine ranking, leading to decreased organic traffic and revenue.
Google’s PageSpeed Insights tool measures TTFB as part of its performance analysis, highlighting its importance in SEO. It is important to note that TTFB is just one of many factors that affect SEO, but it is an essential one nonetheless.
How to measure TTFB?
Various tools are available to measure TTFB, including web-based tools and browser extensions. One popular tool is the Pingdom Website Speed Test, which provides a detailed breakdown of a website’s performance, including TTFB. Google’s PageSpeed Insights tool also measures TTFB and provides recommendations on how to improve it.
It is important to note that TTFB can vary depending on the user’s location and the server. Therefore, to get an accurate measurement of TTFB, it is recommended to test from multiple locations.
Factors that affect TTFB
TTFB can be affected by various factors, including server location, server load, network latency, and caching. Server location plays a crucial role in determining TTFB, as the distance between the user and the server can affect the time it takes for data to travel back and forth.
Server load is another factor that can affect TTFB. If a server is overloaded with requests, it may take longer to process each request, resulting in a slower TTFB. Network latency, or the time it takes for data to travel between the user and the server, can also affect TTFB. Various factors, including slow internet connections and network congestion, can cause this.
Caching is another factor that can affect TTFB. Caching is storing frequently accessed data in a cache, allowing faster access to that data in the future. As a result, caching can reduce TTFB by reducing the time it takes for the server to process a request.
Tips to improve TTFB
There are various steps you can take to improve your website’s TTFB, including:
- Choose a reliable hosting provider – A reliable hosting provider can help ensure that your website is always up and running and has the resources it needs to handle requests quickly.
- Optimise your website’s code – Optimising your website’s code can help reduce the time it takes for the server to process a request. This can include minifying your code, reducing the number of HTTP requests, and compressing your files. We call this the ‘Fix Left’ approach to optimisation.
- Use a Content Delivery Network (CDN) – A CDN can help reduce TTFB by caching content and delivering it from a server closer to the user.
- Implement caching – Caching can reduce TTFB by storing frequently accessed data in a cache, which allows for faster access to that data in the future.
- Reduce server load – Reducing server load by optimising your website’s code and implementing caching can help ensure your server can handle requests quickly and efficiently.

Conclusion and final thoughts
TTFB is critical in determining a website’s overall speed and performance, affecting both user experience and SEO rankings. Therefore, understanding the importance of TTFB is crucial in optimising website performance and delivering an exceptional user experience. By choosing a reliable hosting provider, optimising your website’s code, using a CDN, implementing caching, and reducing server load, you can improve your website’s TTFB and ensure your users have a fast and seamless experience.
Remember, TTFB is just one factor affecting website speed and performance. By taking a comprehensive approach to website optimisation, you can ensure that your website is fast, reliable, and responsive, delivering an exceptional user experience and driving traffic and revenue.
