A bit longwinded but this is perhaps an uncommon issue: We are considering starting a new company (but under same ownership) and would like to move all of our google advertising over to a new account with this new company. The original company would remain, and would continue to sell some similar and/or identical products, but would eventually not utilize google adwords at all as to avoid double serving policies. However, we cannot afford for this transition to occur all at once so we would like to, over the course of 8-12 months, gradually move 1 or 2 campaigns (1-2 product lines) at a time over to a new account (new display and destination url) whilst simultaneously canceling the same/similar campaigns in old account so that there would be no double serving (double ads, double keywords etc..). We would still be using two accounts during this transition with similar products and prices (but never a same campaign and/or identical ads or keywords at one time; and certainly never two ads on a page for the same product(s)). We would have to achieve this transition gradually because we plan to grow the new company slowly and sustainably-only adding 1-3 (or more) product lines per month. Is this possible or perhaps a suggestion as to another option? Is what I have described a realistic exception request that may be posed to google? We are looking to maintain complete transparency with google, but before contacting our adwords rep we want to research and perhaps get some feedback. Sorry for the long post. Any info appreciated.
Just tell Google. Get a MCC and run both accounts joined at the hip. This gives Google confidence that you are not pulling a fast one. Your obligation is to make sure you down bid on the same keyword in both accounts. It's so critical and that getting API access and getting a script built to check for this could be worthwhile
