Mobile Speed on Your Website: How One Second Can Cost You Millions

Written by Team SI on Tuesday, April 02, 2019

In a split second, you can lose or gain a customer.

More than half of website traffic comes from mobile, according to Google. But when dealing with conversions, Google says the mobile rates are lower than desktop. That’s because mobile sites aren’t delivering a great user experience.

When it comes to mobile page speed, Google states that the probability of someone leaving the website is 32 percent when the page load time goes from one to three seconds. Change that to five seconds, and the bounce rate goes to 90 percent. By 10 seconds, it has jumped to 123 percent.

In the retail business, Google’s research indicates that a one-second delay in load times can impact conversion rates by up to 20 percent.

So, to close mobile sales, you need to meet the customer’s needs where they are. You have just a few seconds to make a good first impression, so invest in making your website mobile-friendly.

Here are a few things you can do to increase your mobile speed:

  1. 1. Prioritize images. Decide which images are actually needed and which ones could be best explained in a single image over multiple images or a GIF to decrease load time.
  2. 2. Decide which images to load first, which will likely be the ones appearing above the fold.
  3. 3. Choose a recognized image format, including WebP, JPG, PNG and SVG files.
  4. 4. Resize or compress your images.
  5. 5. Make sure you don't have broken links or broken code.
