1-2 seconds is the perfect website load time for mobile devices

For 46% of users, waiting for a page to load is what annoys them the most when browsing websites on mobile devices[3]

Long loading time can increase cart abandonment by almost 30%[4]

Research by Radware has found that slow loading times can increase cart abandonment by as much as 29.8%. Obviously, you don’t want that in your online store!


4 out of 5 internet users will exit your site if the videos on the site stop loading[5]


There are many reasons why website owners add videos on their pages. However, it is vital to make sure that watching them is not inconvenient for the user. Otherwise, it can negatively influence the statistics.


Almost 40% of users stop interacting with the website if the images do not load[6]


While the percentage is much lower than in the previous point, you should not neglect the issue of loading images. As many as 39% of internet users declare that they resign from browsing a website where graphics do not load or load for too long.


Websites that load in five seconds on average get 70% longer sessions[7]


Compared to websites that load in 19 seconds, pages that load in shorter than 5 seconds get an average of 70% lengthier sessions. The shorter the page loading time, the more time users spend on it.


Mobile websites that load in 5 seconds earn twice as much from mobile ads as sites that load in 19 seconds[8]


This data shows that loading speed impacts your direct ad revenue. The conclusion is simple – you have to make sure the mobile version of your website loads quickly!


Pages that load in two seconds have an average bounce rate of 9%, and pages that load in five seconds have a bounce rate of 38%[9]


Another information confirms that the fast website convinces users to stay there and read the offer. However, it turns out that a page load time of 5 seconds may not be enough to achieve satisfactory results.


Over 40% of visitors who have had a bad experience with the site tell their friends or family members about it[10]


As if it was not sufficient that the abandonment rate boosts due to the delay in loading the page, the same research revealed that users are willing to share this information with their loved ones.


The average content size on mobile pages is 1.49 MB[11]


That means loading such a page with a 3G connection takes 7 seconds, more than the optimal 5 seconds.


Most mobile websites don't meet Google's speed requirements[12]


According to Google, the ideal speed of loading a website on mobile devices is 3 seconds. However, according to the survey, 70% of websites do not meet this requirement and load much longer. Google analyzed as many as 900,000 mobile websites in 126 countries. So perhaps you should take care of the speed of your mobile version of the website and stay ahead of your competition?


Just 100-millisecond retardation in loading can induce a 7% reduction in conversion rate.[13]


According to Google, just one whole second of website hesitation commands you a 70% reduction in conversion. As you can see, every second counts. The higher the speed, the higher the conversion.


73% of mobile users say that they have encountered pages that take too long to load[14]


Nobody likes slow-loading websites, especially mobile ones, e.g., when we need to quickly find important information on our way to work or in the store while shopping. But, as you can see, a significant number of internet users indicate that they have encountered websites that were too slow in their opinion.


79% of buyers who are dissatisfied with site performance indicate that they are unlikely to make any purchases on the same website[15]


Most consumers do not return to sites that leave a bad user experience.

Amazon, like BBC, shared information about how delays in loading their platform affect the company's financial results. Each additional second was reducing their revenue by 1%.


Every second of delay for Bing resulted in a 2.8% drop in revenue[19]


It's not just Amazon that has felt a decline in revenue due to the slow website. Bing also found that every extra second it took to load resulted in a drop in revenue. So two seconds is already a 4.3% decrease in revenues. Quite a lot, right?


Exceeding the page load time by just one second can increase the bounce rate by as much as 123%[20]


You read it right. This statistic shows that the bounce rate can exceed 100% if the website is too slow. Of course, you shouldn't ignore such an essential factor as the bounce rate because it doesn't directly affect your ranking. Instead, it shows that your potential customers leave your site before knowing anything about your offer.

The speed of the site affects not only the activities of service or commercial companies[25]

12% increase in bounce rate for adding 160 KB of images[26]

So, it’s essential to understand why your website is running slow and try to find a solution you can implement to eliminate this problem. Thanks to a faster website, your business has a chance to gain a lot of revenue.
