When you run on RevC, how do you determine which topic is the most suitable to run on? For a blacklist campaign
Any type of reverse engineering to be done to find a better performing topic?
If you want to blacklist categories before running any traffic it will never be accurate.
At best you can try to match the offer type with a suitable list of categories.
Otherwise you could start sending some traffic and be aggressive with the category blacklisting.
Use the LP CTR as an early indicator so you won't have to spend a lot testing initially.
