So I had a campaign running in google to a specific ad, after 2 days I returned to find that most of the phases I had purchased where no longer valid as the bidding price had risen beyond my maximum bid.
Some from 10c to $1!! I then made a new campaign and for my own curiosity used some of the same phrases as in the 1st campaign. Surpisingly I could purchase the same words for less than the new suggested price in the 1st campaign, the following day some of the phrases needed rebidding but the minimal bidding price in campaign 2 was still less than the minimal bidding price in campaign 1.
Whats the deal? I find it deplorable that such a difference can exist for exactly the same phrases and additionally that the increase from 10c-$1 over night is legal to start with......thats a increase of 1000%
