How Site Speed Impacts Mobile Ecommerce Conversion Rates

Mobile Commerce

We integrated a rewards program and developed several personalized and sophisticated marketing automation flows for an e-commerce client that dramatically increased their revenue.

As we continued to watch users flow from the emails through conversions, we identified several issues with their hosting and platform that were significantly impacting site speed – frustrating their potential customers and driving abandonment rates upwards – especially on mobile devices.

Why Page Speed Matters

Why Page Speed Matters to E-Commerce

It’s great to work on marketing acquisition, retention, upsell, and increasing average order value automation for e-commerce… but unless your site speed and the shopping experience are outstanding, you’re not maximizing your return on marketing investment. As well, your e-commerce site has to be tested a number of different ways to ensure speed is consistently good:

  • Is your e-commerce site consistently fast on all browsers?
  • Is your e-commerce site consistently fast on all mobile devices?
  • Is your e-commerce site consistently fast on all desktop devices?
  • Is your e-commerce site consistently fast in all geographic regions you serve?
  • Is your e-commerce site consistently fast when you have a lot of visitors on your site?

Segmenting your site’s speed performance and measuring conversion rates throughout these segments is critical and can point to some glaring issues that will impact conversion rates.

Mobile E-Commerce Site Speed

Consumers no longer have any apprehension at shopping on a mobile device as they once did. Mobile e-commerce is quite finicky… if your visitor is watching another screen or in a conversation and shopping on their mobile device, your speed, and conversion path have to work effortlessly, or else they’ll bounce altogether or abandon the cart they’ve started. Take a look at the dramatic behavioral differences between devices:

  • A mobile visitor is more than twice as likely to bounce from a site than a desktop visitor.
