One SEO Professional was concerned about certain fluctuations in data they had noticed as they analyzed the page experience section in Google Search Console.
One day they may have 20,000 good pages. Yet, another day that number is reduced to just 1000 pages.
During the next week, they might not see any data for the week prior.
They are seeing another picture with another date every week in Google Search Console. They are confused about what this means in terms of data and what they may need to do on their site.
John explained that this is likely an effect of how they actually track this data in Google Search Console.
He revealed that this data is heavily sampled and is based on what they see from users. They track just a specific kind of user.
When they have enough data surrounding this kind of user, then they will be able to show this in Google Search Console.
Within Search Console, after they have enough data, they will create groups of pages where they believe this set of pages is the same.
This also means, however, that if there is insufficient data, then they probably will not show it.
This is why you will see some situations where you will have a lot of data, and then it will drop again.
Over time, the overall number could go back up again.
If the good number goes down, and then the bad number goes up, then this could be a sign that there is a problem that Google is seeing in that situation.
For situations where the overall number goes down, John says he would just ignore it.
This happens at approximately the 37:27 mark in the video.
