Everyone tells you to set up conversion tracking correctly
But nobody tells
What to do when your conversion tracking is broken unexpectedly?
If you have a campaign that was running perfectly with smart bidding and suddenly you face an issue with conversion tracking
that campaign can get a huge impact from that issue because the data smart bidding used in the period of that issue is wrong
If you have an issue with conversion tracking and if that issue isn't fixed for a while its going to impact in smart bidding because smart bidding is solely based on conversion data
Even if it is fixed right away you don’t want smart bidding to learn from the time frame that conversions weren't recorded properly because data recorded in that time frame was wrong
You can fix this by enabling data exclusions during that period
What happens when you enable data exclusions is you tell smart bidding not to learn from that specific time frame where conversion tracking was broken.you just erase it from its mind
You name a specific time frame and tell smart bidding this is bad data and don't learn from it
So to do that you need to identify the data frame correctly where it was broken and fixed and to be safe you need to add extra 1-2 days prior and before that time frame
So if the conversion issue was occurred in March 11 and fixed in March 20 your exclusion time frame would be from March 10 or 9 to March 21 or 21
You can head to Tools>Budget and bidding>Adjustments>exclutions and add this time frame to affect whole account or specific campaigns that use smart bidding
