What will happen if I do not set content bid to 0 for Display Network only campaigns?

Hi, According to this blog post, we have to set the content bid to 0. I wanted to know what will happen if I do not set the content bid to 0. Will this cause any problems? Thanks, Aradhya -- -- =~=~=~=

Hi Aradhya, It depends on the current state of your default ad group bid and your content bid. - If default bid = contentBid, then nothing will happen - If defaultBid != contentBid and contentBid != 0, AdWords will overwrite the defaultBid with the contentBid when the change goes live
