Let's say I've two websites... one if them is getting low ctr and one is getting very high ctr (for example 50%) Both the websites in one channel -- or there's no channels --, so the total ctr is 10% or less. Will this make any suspicions?
Why peoples think about CTR and suspicions, because its not matter even if your CTR is 75% its OK if you dont do anything against G's TOS... IF you do something against their TOS you are never in the safe side....
