What PageSpeed score should I aim for?

In a nutshell, you should make your website as fast as possible. A page load time of 1-2 seconds is a good goal.

In terms of Google PageSpeed Insights, a score of 90 or above is considered good. 50 to 90 is a score that needs improvement, and below 50 is considered poor.

In a study of page load speed, Google found that:

As page load goes from:

• 1s to 3s the probability of bounce increases 32%

• 1s to 5s the probability of bounce increases 90%

• 1s to 6s the probability of bounce increases 106%

• 1s to 10s the probability of bounce increases 123%

A common standard for page load time comes from a study conducted by Geoff Kenyon where he compares website speed against the rest of the web:

If your site loads in:

• 5 seconds, it’s faster than 25% of the web

• 2.9 seconds, it’s faster than 50% of the web

• 1.7 seconds, it’s faster than 5% of the web

• 0.8 seconds, it’s faster than 94% of the web

In other words, time is money.
