I effing hate clients like that. I won’t even work with those micro-managing types anymore unless I absolutely have to. These days I am so busy that I can be a bit more picky who I work with.

I think as long as the numbers continue to improve (more conversions, higher CTRs, lower CPAs, stable or higher ROAS, month-over-month), then clients should back off and let you do your work. But some just insist on wasting your time with pointless things like yours is.

Edit: If he is really that concerned about it, find out the head office zip code and create a campaign only targeting that one zip code at a low daily budget.
