Since 2010, page load time has been added as one of the ranking factors utilized by Google rankings. While some say it’s not a particularly strong ranking signal in itself, it’s a metric that has a massive knock-on effect on other important metrics, including sales and revenue.
There are many different studies suggesting that page load speed directly impacts conversion rates and sales. A study done by Amazon concluded that if their pages load just one second too long it could cost them $1.6 billion in sales each year. Google has calculated that if their search results take just four tenths of a second more they could lose 8 million searches per day, which ultimately impacts in huge losses in ad revenue.
In an A/B test done by Shopzilla, comparing the impact of the download speed their pages had on conversion, they found that their faster pages delivered 7 to twelve percent more conversions than the slower pages.
Some small and medium-sized businesses have been working on page load time to generate revenue. UGears, which produces self-assembled, high quality mechanical models, had a successful crowdfunding campaign, raising over $400,000, but they needed to build a long term, sustainable revenue source.
Running the free website audit tool Plug in SEO, they identified specific issues including page load time, on-page SEO and blog. Now, 25% of their revenue (and growing) comes from organic sources. Co-founder Dmitry comments: “We can clearly feel the increase in sales following the page load improvements.”
If we put ourselves in the shoes of an average consumer, this shouldn’t come as a surprise. With higher competition and lower attention span, every millisecond counts. An article by The New York Times titled “For Impatient Web Users, an Eye Blink Is Just Too Long to Wait” showed that users begin getting frustrated after waiting for just 400 milliseconds for web pages to load.
At Compass, we have access to a growing data set that tracks over $6 billion in annual ecommerce transactions. Looking at this we asked, how does page load speed impact the most important business metrics for hundreds of online stores? This is what we found:
If your page takes 2 extra seconds to load, bounce rates go up to 50%
Bounce Rate is a metric that evaluates how many people leave your site without performing any action, which strongly indicates that they’re not having a good experience with it. Following the red line in the graph below, you can see that slow websites have considerably worse bounce rates than fast ones.
If your site is slow, people get impatient and bounce to shop elsewhere. And this is only the tip of the iceberg. Since a bounce only counts when a user allows a page to load fully and then leaves, slow websites are probably losing a lot more people than our numbers indicate.
Conversions fall by 12% for every extra second it takes for your page to load
Conversion rate is a metric that calculates how many of your website visitors convert into shoppers. Following the red line below, notice that page load time also has a direct impact on conversion rates. The slower your website is, the worst your conversion rate will be.
Bad conversion rates negatively impact the effectiveness of advertising campaigns, making it much more expensive to acquire customers.
Revenue increases by 3.2% if you improve average loading speed from 4 to 2 seconds
We were surprised to discover that the impact of improvements in page load speed seem to be more significant for companies who already have fast websites.
As you can see in the graph below, the Increase of Revenue curve is steeper for faster sites. A steeper curve indicates that having a fast website gives all the more reason to optimize it further.
Merchants who sell cheaper products also seem to gain the most by optimizing their websites for page loading speed. As indicated by the graph below, improving page load speed appears to have a stronger effect on ecommerce sites with an average order value lower than $50.
What You Can Do to Increase Page Load Speed
- Keep an eye on image sizes, especially in areas like a homepage slideshow or hero section of your site, ensuring that they’re sufficiently compressed. Use tools like Crush.pics to help you.
- Make sure all of the page components are hosted on fast web servers.
- Make sure that above-the-fold information loads as quickly as possible. Use lazy loading for everything else.
- Measure the range of real-world load times by sampling your visitors using tools like Google Analytics > Behavior > Site speed.
