How To and How Not To Use Google PageSpeed Insights

Nowadays both customers and business owners value speed and efficiency above most and it's easy to get caught up in the race. Not all is always what it seems, however! When looking at website speed tests (we'll look at Google PageSpeed Insights in this case) there are a few pitfals that you may want to avoid. We'll show you the most common "offenders" to your website speed ranking when using Google PageSpeed Insights so that you don't panic, when there is nothing to panic about! We'll also provide you practical suggestions that you can follow to keep your website fast and efficient.

Many clients worry from time to time about the performance of their websites, especially after the latest Google PageSpeed Insights tool updates in summer 2018. Many website owners saw their scores go down dramatically overnight.

I will start with the most important thing - the main score that you see after testing your website is based on lab data and not on field data! If you see a red circle with a very low score it doesn't necessarily mean that your website is slow for your customers.

To make it more clear how the tool works, you need to understand the difference between lab data and field data. Here's what Google has to say about the difference between the two.

And so, the lab data analysis is only tested through a single device and set of network conditions, but if your customers have better devices or network conditions then their experience will definitely be much better than the test suggests.

The field data analysis show the real customer experience on your website during the last 30 days! So this is the one metric that you should be interested in the most.
