In today's world wide web, we're using multiple devices to surf the internet.

Mobile enjoys approximately 50% of the total device usage.

What you tend to find is that the initial search is performed on mobile, with final decisions and purchases finalized on desktop devices.

Business owners would be wise to make sure the page speed for all devices is optimal for their website(s).

We now have Progressive Web Apps (PWA) and Accelerated Mobile Pages (AMP) to rapidly speed up mobile websites, but most businesses are still using responsive or adaptive designs for their websites.

At Browserweb, we took a long hard look at AMP when it first came out and yes, it's fast, but in effect it's stripped out HTML, like your reader view on your phone.

It takes a lot of customization to make it more visual and with forms on-page.

We prefer visuals and interactive designs and, like many, have held off making the switch to AMP.

The more recent PWA seems a better solution, however, we've not delved into PWA. As most of our "challenge" websites below are using responsive designs for mobile, we've excluded PWA and AMP from the results.

Hence, any website 12 seconds on under for mobile is currently a good barometer.

You'll see much higher page load times than desktop on mobile devices and as you can see from the results, only Browserweb with 5.6s, Google with 5.9s, and Shopify with 6.2s that came in under our benchmark 12 seconds.

To put that into perspective, only 3 out of 8 websites in our challenge loaded faster than 12s.  Mobile page speed is still evolving but over 12 seconds and your conversions will be negatively affected.

This month, we elected to look at eCommerce vendors, and also compare not only desktop page speed load times, but mobile as well.*

As a benchmark, rather than just using our own website, we decided to run with Google's "Think with Google" website, which we've reported on in the past.

As Google is the one "beating the drum" as it were for fast loading mobile experiences, it seems appropriate.
