I have originally posted in this topic: https://support.cookiebot.com/hc/en-us/community/posts/360012258433-Missing-data-missing-traffic-30-to-70- But I assume that since it is marked as "answered", it is not pushed to the top of the list. Since this issue has grave consequences for our and many other companies, I believe we need a more detailed / correct answer than the one given so far.
The post again:
It's hard to imagine that such an extreme drop is due to users not making a decision (therefore not being tracked). Here are the numbers:
In the 14 days from Feb 18 to March 2 we had 307 users on average per day on site 1 (as measured by Google Analytics). From March 3 we started using Cookiebot and *immediately* the number of users dropped sharply to 151 per day in the following 14 days from March 3 to March 16. The Corona measures only hit Germany hard from March 16, so this can’t be the reason. From the numbers we would have expected that in the “User consents” menu we would see around 307-151 = 156 opt-outs on avg. per day from March 3 to March 16. However, it only shows 81 on avg. per day in that timeframe. I would like to know why Google Analytics shows twice as many users lost compared to Cookiebot opt-outs.
While the former could, with some imagination, be attributed to users who did not make any decision, this cannot: On site 2 pre-Cookiebot we had around 300 users per day as per Google Analytics. After Cookiebot implementation we have about 90. That is a drop of about 210 users or 70%. Cookiebot, however, only reports about 25 opt-outs per day (ca. 10%)!
You also have to note that we use the banner which (annoyingly) stays at the bottom until a user makes a decision, so we assume most users make a decision at some point in their session.
