Have you ever wondered just how fast your site actually needs to be to be in order to deliver the right level of customer experience to your clients? For example, what’s the difference between one second to load and two seconds? What about on the other end of the spectrum? Is there a point of diminishing returns on how fast your site is?
There’s a lot of great content floating around about how to make your webpage faster, and I’d like to ground that in some real-world data that will explain *why* speed is so important to web performance.
At WP Engine, one of the things we work tirelessly on is having the fastest-possible WordPress hosting for all sizes of sites, from the enterprise to the solo blog. We’re convinced that faster sites win the day when it comes to pageviews and SERPs. Here is some of the research behind that.
Why there are only 10 results per Google Search
One of the things that matters to user experience on the web is how quickly users are able to find what they are looking for. Google measures their success as a search engine by how quickly they can get users off the Google homepage and onto their search results.
When Marissa Meyer was at Google, she performed a survey around user experience to find out whether Google searchers preferred having 30 results per search result page, or 10 results per page. People overwhelmingly reported that they preferred having 30 results per page.
Google tested new pages with 30 results, using the original 10 result pages as a control. They discovered that the pages with 30 results per page delivered 20% less traffic than the pages with 10 results. Turns out, the pages with 30 results were loading just a half second slower than the other pages. That half-second was enough to reduce the traffic Google sent to those pages because people weren’t sticking around to wait.
Speed is A Competitive Advantage
Since 2010, Google has been factoring page speed into their search engine results. In their tests, they’ve also demonstrated that the longer users are exposed to slow web pages, the fewer searches they perform.
From the research listed above:
“Users exposed to a 200 ms delay since the beginning of the experiment did 0.22% fewer searches during the first three weeks, but 0.36% fewer searches during the second three weeks. Similarly, users exposed to a 400 ms delay since the beginning of the experiment did 0.44% fewer searches during the first three weeks, but 0.76% fewer searches during the second three weeks.”
Essentially, the slower a site is, below about 1.5 seconds, the less frequently users will return to the site.
Faster Sites Make More Money
Needless to say, if you’re operating a site that generates revenue based on pageviews or conversions, the above data is pretty compelling. The more you can do to boost the page speed of your sites, the more revenue you’ll generate.
Amazon.com did some research to find out how much revenue a second of load time might mean for their site. How many fewer sales would a single second of additional load time mean for Amazon? The lost revenue would total $1.6 billion, which, even for a company as massive as Amazon, isn’t a rounding error.
Are You Not Entertained?
Now then, there are a series of other articles here that explain how you can make sure your site is as fast as possible. Generally speaking, as long as the site takes less than 1.5 seconds to load, it’s fast enough. If you get pageload time below one second, you’re crushing it.
