What Is the Impact of a Slow Website on Your Business?

A few seconds can significantly impact your business's bottom line when it comes to page loading speed. If your website takes too long to load, potential customers are likely to leave and you may end up loosing revenue.

That's why we decided to calculate the impact of page speed and related metrics on website revenue, especially for sites that earn revenue through ads.

While we're focusing on ad revenue, if your business relies on high-quality leads and large deals, a slow website can be equally devastating.

Here are some examples that illustrate the business impact of site speed:

  • Google discovered that increasing page load time by just half a second (from 0.4 to 0.9 seconds) led to a 20% drop in revenue and traffic.
  • According to GQ Magazine, after reducing page load time from 7 to 1.5 seconds, the number of unique visitors jumped from 6 million to 11 million in just one month. Furthermore, the median time spent on the website increased from 5.9 to 7.8 minutes, leading to a 108% increase in ad interaction rate.
  • A 1-second delay in page load speed resulted in a 4.9% decrease in the number of articles read, while a 3-second delay caused a 7.2% drop.

    • Formulas used in the calculator:

    ELT = PS - TLT

    RL = MT x (ELT / 1000) x RPM x (BR / 100)

    Explanation of Variables:

  • RL: Revenue Loss
  • MT: Monthly Traffic
  • ELT: Excess Load Time (in ms)
  • PS: Page Speed (in ms)
  • TLT: Threshold Load Time (in ms)
  • RPM: Revenue Per Thousand Impressions
  • BR: Bounce Rate
