Google Analytics defaults to collecting 1% of page speed measurements. This may be helpful if you have a large amount of visitors but for most websites this is far too low. Let’s increase this number to get more data points.
If you have your Google Analytics set up with Google Tag Manager, you can add a new variable called “siteSampleSpeed” and set it the percent you’d like to collect (i.e. 100.)
Here’s how to do it:
Google limits the number of site speed samples to 10,000 per day per property. If you have a large number of visitors you may not be able to see every visitor’s data.
