Are Site Speed and Mobile Friendliness Related?

There is a wide range of correlation between Site Speed and Mobile Friendliness. The correlation is not necessarily linear – there are sites that have very high speed but low mobile friendliness and sites with very low speed but high mobile friendliness.
The relationship between these two factors may not be surprising, but the exact degree to which they are related has been surprising to many, as can be seen from the following graph:

In this analysis, the Y-axis represents the inverse of time taken to load a page. Likewise, the X-axis represents relevancy of a site’s content for a mobile device. The red line indicates the best fit line, showing that there is a strong correlation between Site Speed and Mobile Friendliness. Therefore, it might be wise for a company to focus resources on improving both factors at once rather than trying to focus only on one factor at a time. All of the freelance seo expert always shows concern when we talk about the mobile responsiveness of a website because there are a lot of people use mobile for searches.

The mobile-friendly label, introduced in Google’s search results to help users find websites that work well on mobile devices, has been incorporated into the algorithms of many search engines. The label is applied to sites that are both fast and responsive.

The two concepts are not identical. A site can be either one without being both. A site can be fast without being mobile friendly, for example when it uses a desktop-only site template. And a site can be mobile friendly without being fast, for example if it runs very slowly but is still usable on a small screen.

The close relationship between the two concepts is reinforced by the fact that, when Google measures how well a site performs on mobile phones, the metrics used are exactly the same as those used when measuring site speed. Both are based on page-loading time, which Google measures in Chrome via loading speed timings .
The question is whether there are any significant differences between sites that earn the mobile-friendly label and sites that do not.

Speed is a critical factor when it comes to conversion. People are more likely to abandon a site that takes more than 3 seconds to load, and also less likely to revisit it. When Google announced their mobile-friendly algorithm update, I bet they cared about page speed.

Speed can be difficult to define. While most of us know when a site is slow, even the most knowledgeable of us is not always able to tell you what is slowing down their browsing experience. And when they do know, they’re not always sure how to fix it.
This has led many people to avoid the issue altogether by adopting the mantra of mobile-first design . However, that’s not necessarily the best approach for your ecommerce site. There are two main reasons why:

1) Your desktop visitors may be just as important as your mobile visitors. They may even be more so, if they are larger purchasers.
2) Mobile-first design tends to prioritize quantity over quality in terms of content and functionality provided on your ecommerce site.

This is a simple test case of something that happens a lot in software engineering. You develop some new feature or capability, and then you realize it has some other consequence, which you didn’t think about when you were planning it.

For example, a while back I noticed that the way I had implemented a certain feature in the parser led to the program crashing when fed particular bad input files. It took me some time to figure out what was going on, but eventually I realized that it had to do with the feature I was adding.

Of course the ideal situation is not to add bugs in the first place. But that’s hard, and sometimes there’s no choice. In this case, the bug was in how I had implemented a certain feature; if we had put off adding that feature until we had more time to think about it and test it, we would never have found the bug. And even if we’d noticed in advance that it might create another problem, we probably wouldn’t have spent much time worrying about it; we’re under pressure to get features out before they’re ready because our competitors are always one step ahead of us.
