So we have: Today, Yesterday, Last week, Last month, Last 7 days, Last 30 days. So we just turned into 2021, yet the default date filters in GA look like from 1985: Make your reports less and complex – the favorite solution of Google support. Or you can just select “last 8 days” instead of the preset “last 7 days” and again…there is a big chance your data will be sampled. It’s enough for you a to pick a few dimensions, set up a slightly more complicated filter in custom report and you can bet the data will be sampled. Sampling is present in default reports, in custom reports, in attribution reports. I’ve seen a great deal of sampling happening in properties which cost thousands of dollars in GA fees just to run every month. Sampled data is useless 90% of the time so the only choice you have is to wait for an Unsampled Report which may never come! More on that later. Sampling is a big issue in big GA properties. However, all these issues are happening in paid GA 360 properties. I want to make one thing very clear at the beginning – if these issues were happening just in free Google Analytics then fine… It’s a free product so I expect nothing.

Also, I have never seen a nice “GA issues” list so I’ve decided to summarize all my important findings. Summarize all the known GA issues – I am frequently googling for GA issues and I am quite surprised how few people write about the below mentioned problems.If you run GA in a big company with lots of hits and events, all these issue are probably your daily bread even though you pay significant GA fees to Google.

If you run a small site with a couple hundred visits per day, you may have never experienced sampling for example. This article is based on working experience with several big GA properties (the old setup, not the new GA4s which are currently in beta). The things start to get a little complicated and frustrating when you try to get more complex data involving multiple dimensions and metrics over a longer period of time. If you look at Google Analytics sessions to check for high level metrics such as sessions day over day, then you are probably fine and you don’t really experience any issues.
