1 – No, not at all. These are not all going to be targeted the same way, and the bids shouldn’t be the exact same anyway. So, you shouldn’t be causing any overlap or bid wars against yourself.
2 – Yeah, most likely it will need to be reduced in order to stop bidding against yourself so high. But the research bids shouldn’t be as high as the Top Converting generally, but you still need to make sure both are profitable obviously.
3 – You can add keywords to the Research Campaign ONLY when they show up in the Match Type in the search term report. For example, if your Auto Campaign shows a new search term getting sales under a Phrase Match keyword, then you can add it to the Phrase Match Ad Group of the Research Campaign. Hope that makes sense.
