Did you know that for every second it takes to load your website, you’re losing customers? And if it takes more than three seconds, you could lose more than 50% of visitors? (1)
Today’s consumers expect most things on demand. From pizza to packages to taxis, we expect it fast. And this is even more true for our websites.
If your website’s reaction time is too long, chances are, customers will try their luck elsewhere. That means you can lose customers, lose business, and lose money—all because you didn’t take the proper steps to improve your server response time.
If you think your website is loading slower than it should and it’s costing you money, this comprehensive guide is for you. Upon its completion, you’ll know the full story on how to lower your servers’ response times and get those customers (and profits) rolling in.
What Exactly Is Server Response Time?
Q: What is response time?
A: Response time is how long it takes for a web server to respond to a request from a user.
Whenever you click on a link, type in a website in the URL bar, or otherwise access a web page, you are actually sending a call to a server to allow you to view the website in question. The server response time is the amount of time between your call and the server “responding” to that call or how long it takes for the server to begin rendering the page’s info for you.
Web response times are measured in TTFBs. What is TTFB? It means “Time To First Byte”, or how many milliseconds passed between your request and the server’s reply.
4 Ways To Lower Server Response Times
Technically, there are many ways that you can lower server response times (or TTFB). But we can pretty much boil it down to four crucial steps.
1. Choose The Right Host And Server
This first step is the most crucial because everything else will follow—what servers you can use, how much resources you’ll have to handle users, what kind of speeds you can expect off the bat, and your customization options as well.
Compare and contrast different options (WPX Hosting, Nginx, Apache, and OpenLiteSpeed are some of the names that immediately come to mind) to find one that is affordable, complete, and can be scaled up as your needs grow.
2. Optimize Your Server
After choosing your web host and server, you have the option to configure the settings. It might be a little intimidating to do so, especially if you don’t have any prior work doing so. But optimizing your server—doing things like enabling a cache, using a content delivery network & making sure you use HTTP/2—will make a huge difference in reducing your website’s reaction time. Plus, it’s absolutely free to do.
3. Eliminate Bloat
Eliminate bloat by removing the things you don’t need. This includes uninstalling plugins you don’t use, removing non-responsive images, and trimming down your code.
4. Optimize Your Resources
Dean Hume, software developer, and author praised the use of responsive images in image optimization, saying this: “By using responsive images, you can tailor the image sizes to suit the browser’s viewport and in turn, save on the total download size of your web pages…You can save your users bandwidth and ensure speedy response times at the same time!” (2)
Which Factors Affect The Load Speed Of A Website?
Q: Which factors affect the load speed of a website?
A: The factors that affect the load speed of a website are your server’s capacity, the use of third-party plugins, the number of images on a page, and the user’s own internet speed.
If you’re not getting the speeds you expected (or were promised), there are a few things you can look at when figuring out how to improve your servers’ reaction times.
- Website traffic: If there are more users clicking around your website than it can handle, it could slow down your server reaction time. This may even prevent some users from accessing your website at all.
- Server settings: As we’ve mentioned before, if your server isn’t optimized, your users will be faced with slower reaction times.
- Caching: Caching helps your server render your content faster and more efficiently. Instead of making a new call every single time, caching allows the browser to pull up the assets from a local cache instead, speeding up the process.
- Bloated resources: Websites with tons of plugins, apps, extensions, pages, and images will naturally take more time to load than sites with less.
- Web host: Sometimes, the problem is simply your web host. If it’s dirt cheap or unreputable, you might not be getting the latest equipment. You might also be sharing bandwidth with dozens, hundreds, or even thousands of other sites.
How Fast Is a “Good” Server Response Time?
Q: How fast is a “good” server response time?
A: A good server response time, according to Google, is under 200 milliseconds. (3)
When Google rolled out ‘The Speed Update’ in July 2018, having a quick reacting server was crucial. The update negatively impacted sites that were delivering slow load speeds, causing their search engine ranking to go down (more on this later).
Why Time To First Byte Is Important For SEO
While things like content, link building, and anchor text analysis are often cited as the most important SEO practices, page speed is a pretty important factor as well, that many site owners mistakenly overlook. So, does your server’s reaction time really matter or is it just another thing for you to think about?
Because of this, sites with very slow load speeds can be penalized with lower rankings on the search engine results page. That means if someone searches for keywords that are relevant to your site, you will appear lower on the results page—or maybe not even at all.
Just by having a long server reaction time, you could be missing out on the opportunity to reach thousands of potential customers.
Tools To Test Server Response Time & TTFB
If you want to be sure your site is up to standard, there are many ways to check server response time. Here are the top server response time checkers and tools.
GTmetrix is a tool that allows you to analyze your server response time, monitor your pages, and test your speed on mobile. There are free and pro versions available.
Through Pingdom, you can monitor your site to get up-to-date info on its performance, speed, and the steps you can take to improve your site.
4. Google Page Speed Insights
If you’re reducing your server response time for SEO, there’s no better speed tester than the one from Google themselves: Google Page Speed Insights.
5. Web Page Test

Summing Up Server Response Time: What To Do Now
Server response time has a significant impact on customer experience and your SERP rankings. Slow load speeds can turn away potential customers and make your website less visible, even to the people who are searching for it.
There are many ways to lower your server response time, like choosing the right host, optimizing your server, and removing unnecessary bloatware. But the first step to a faster site begins with finding out what your actual response time is.
Try out the tools above for yourself! And use that insight to make your website faster, more efficient, and ultimately more profitable.
What’s a good server response time?
The general consensus is that a server response time of less than 200ms is ideal.
What’s a good time to first byte (TTFB)?
Often considered the same as response time, recommended time to first byte is 200-500ms, or better.
How do I fix a slow website?
1) Enable caching
2) Remove slow plugins
3) Optimize your images
4) Minify your code
5) Use a content delivery network (CDN)
What is server optimization?
Server optimization refers to techniques that increase the data processing and performance of servers.
Why is my server slow?
This could happen because the server itself is overloaded or unoptimized, but also because your connection to the server might be laggy.
