It’s essential that web designers create fast experiences across all sectors of the industry. Customers want to pay their bills on finance websites and get quick results when browsing reviews of their vacation and browsing an article right away after clicking through. If the site is causing too much hassle they’ll leave the website and go elsewhere.
The good news is that it’s actually less. When we examined the speed of mobile pages in the past year, the average time required to fully load the mobile landing page has been reduced by 7 seconds. 1 The negative is that it takes around 15 seconds, according to our latest analysis. This is a lot too slow when you consider that faster mobile website speed allows users to visit many more webpages on the website as well as convert more and spend more money on the majority of brands’ websites.
Our research shows that even though more than half of the overall internet traffic comes from mobile devices, the 3 percentages of mobile users convert less as desktop. 4 In short, speed is revenue.
Last month, in an effort to gain an understanding of what Google’s advertising partners are performing in the market, we performed an analysis of the 11 million mobile advertisements’ landing pages that span 2213 different countries. 5 That analysis proved our hypothesis that even though the majority of traffic is happening via 4G rather than 3G, 6 the majority of mobile-based sites are slow and overloaded with too many components.
We dug into a broad range of industries including finance, travel, and tourism. Pages in the retail, automotive, and technology industries generally take the longest time to load. They also have the highest volume of packed pages on the web.
Our research has provided us with a lot of information. For 70% of mobile landing pages that we studied the time it took over five seconds to get the images over the fold to appear on the screen. Likewise, it took over seven seconds to load all the visual content that was above and below the fold.
We also developed deep neural networks–a computer system that is modeled after the human brain and nervous system – using an extensive number of bounces and conversions data. The neural network, which had an accuracy of 90% for prediction determined that as a page’s load times increase between one second and 10, the likelihood of a mobile website user getting bounced increases by 123 percent. In the same way, when the amount of text pictures, titles, etc.–on a page is increased up to 400, the chance of conversion decreases 95%.
Whatever speed is always better, and less is better.
Sometimes, smaller size is more efficient too. We discovered that 79 percent of pages had more than 1MB, while 53% were over 2MB, and 23% were over four megabytes. 9 One photograph, in particular, caught our attention because it weighed more than 16MB.
However, despite the negative information, there are plenty of low-hanging fruits. Simple compression of images and text can make a difference–25 percent of websites could reduce more than 250KB, and 10% of pages could save over 1MB this method. 10 Our study suggests that the travel, retail, and healthcare sectors have the greatest room for improvement.
When you’re dealing with mobile pages the speed and size of the page are crucial. Marketers must ensure that users are interested in their mobiles and concentrate on creating mobile-friendly experiences. Look at the graphs below for a comprehensive view on mobile across different industries which includes guidelines for speed, size of the webpage, and the number of content elements per page.
