We have an account manager and some are more proactive than others, e.g. recently we had an offer to review the campaigns and suggest more terms. We accepted some of the suggestions, so Google makes more revenue while we evaluate the performance of the new terms.
The other benefit was being able to get the entire historical data (deleted and current) in a spreadsheet. We had this data in dribs and drabs, but getting it in one file was great.
At Christmas and other times, the CEO gets gifts such as beach towels.
