As you know slow sites can have a negative impact on revenue, and fast sites are shown to increase conversion rates. Retaining users is crucial to improving conversions. So you can see how speed performance is impacting user experience.

However, besides specific technical methods to improve factors which impact directly on your store speed, for example decreasing the size of images or video to increase your store speed, we would like to bring to you Perceived Speed as an optimal solution to improve your store performance indirectly through improving the user’s perception of time while waiting for or interacting with your website.

I. What is Perceived Speed

Simply, Perceived Speed is how fast your customers think your site is. By prefetching all the resources are highly likely that the user will visit your website based on the Smart Preloading method, which helps your customers land on your site instantly without waiting for a page to load. From that, optimizing Perceived Speed will make your site seem to be loaded quicker than reality.


Collection page on your site needs an average of 10 seconds to load, so we use Smart Preloading to preload resources with high probability on this page before your visitors land on the collection page. So then, once the visitors click on this page, they will be delivered on the page instantly without waiting too much. Here, it can be understood that it helps your visitors feel like your site seems to be loaded quicker than it actually is.

II. Why Perceived Performance matter

Perception vs. Reality

It’s commonly believed that speed is of the essence so rapid and responsive experiences are highly prized and ranked by users on the move of smartphones and mobile devices.

To get a better understanding of exactly how users feel about the role of speed on mobile web, Google has conducted some research and surveys which show that while speed definitely matters on the mobile web, user perceptions of speed can be just as important beside the reality of speed on the mobile web.

According to the study, three-quarters of respondents said that the speed with which a page loads is the most important consideration, compared with factors that affect their overall experience such as screen size and fit, or the attractiveness of a site’s design. This makes intuitive sense, as user goals generally can’t be accomplished on a site until it has finished loading.

Another intuitive insight revealed in this study, is the user perceptions of speed. Respondents ranked seven out of ten visits as loading quickly, which mapped reasonably well against the actual time of those page loads. However, the study also discovered a disconnect, with 75% of users who experienced comparatively slow page loads still perceiving them as having loaded quickly.

From the above survey, you can see speed on the mobile web can be influenced by a range of factors beyond the literal time a page takes to load. One of the first potential explanations to emerge from the study involves the difference between the time after which a site can effectively be used, and the time it takes all of the page’s elements to finish loading. On several websites, above-the-fold elements are given priority, allowing users to begin browsing before the invisible portions of the page have finished rendering. This behaviour is increasingly common and applied with ‘infinite scroll’ sites becoming popular.
As a result, users seem to reward these sites with higher perceptions of speed, because they present a usable experience quickly, even when their literal load times are comparatively slow.

In short, actually Perceived speed won't have a direct impact on your score rate, but it will effectively influence the user's perception of the time waiting your site to load and increase their experience happiness when shopping on your website. Then boost your conversion and sale as well.
