It’s 2017. The ideas of responsive design and your website being mobile friendly are no longer suggestions, but are requirements if you want your site to rank well on search engines.

With that said, not only should your site be mobile-friendly, but you should be optimizing your mobile site speed.

Why, you ask? We discuss below.

Slow Mobile Site Speed: What Happens?

Your website’s speed on mobile is vital. A research report published by QuBit showed that 8% of consumers abandoned a purchase because of slow loading pages. Think about what your site could gain from 8% more purchases.

Also, the slower your mobile site is, the higher your bounce rates become. According to Google’s Daniel An, 53% of mobile site visitors leave a page that takes longer than three seconds to load.  

Think about the potential losses your business is incurring if you’re losing over half of your traffic due to your mobile site’s loading speed.

What’s Wrong With My Mobile Site?

It’s easy to say that your mobile site speed should be fast. But actually having a mobile site that loads fast is another story. Often times marketers and developers struggle to understand why their sites aren’t loading quickly. Some factors are:

  • Page Redirects - Avoid too many page directs. Think of it as being at the airport. You are told that your plane is in one terminal. Once you arrive, you find out that it is in a terminal on the other side of the airport. It’s going to take you a lot of time to get to where your plane actually is. That’s how page redirects work - it’s like your page has to load twice. Avoid them, if possible.
  • Dense Code - If you have HTML/CSS or javascript code that is too dense, it will impact your page speed. Have your developers take a look at your backend to see if this is an issue that is slowing your site down.
  • mobilespeed_body.jpgUnoptimized Images - If you have an image-heavy site and aren’t optimizing and shrinking your image file sizes, they can take a lot of time to load, thus slowing down your visitors’ mobile site speeds.
  • Slow Server - If your website host has a slow server, it will negatively impact your page load speed. Be sure that your server is capable of handling your website and its traffic.
  • Plugins/Widgets - Sometimes websites just have too many bells and whistles and it takes forever for all of them to render. Go through your plugins and widgets and disable the ones that are not absolutely necessary.
  • Caching - Setup caching of your website so that it can be served instantly to your website visitors. This can drastically enhance loading times and is less load on your server.

Page Speed Tools

The tools listed below will help you determine your mobile site speed and offer insights into how you can make it faster.

Page Speed Insight

This is Google’s tool. You input your website and it gives you a mobile and desktop score from your site between 0 and 100. It will list out ways you can optimize your site, along with optimizations you are already doing on your website.


Pingdom allows you to test your website and gives you a performance grade on a scale of 0 to 100. It will also tell you how long it took your site to load, the page size in MB, and then will dive deeper into how certain aspects of your site perform.


Like the other two sites, GTMetrix will give you a grade on a scale of 0 to 100. It also grades your site on over 20 different factors and gives you advice on how you can optimize each of those factors.
