I have seen it many times.
People follow the best practices.
But do you have enough conversions?
I see a lot of the times small accounts that:
– Bid on conversions
– Use Broad Match
But the account only has:
– 2-3 conversions per month
What I would prefer for a small account?
– Phrase or Exact
– Manual CPC
Of course, you need to test things.
If something else works better for you do it.
If it not works keep testing.
