Depends on how much is “some clicks”. If we are talking 50 I would say not enough to give a good reading yet. If it was 2000 then I would say you definitely need to tweak some things.
Some of my BEST campaigns using Facebook ads convert at 0.5% Meaning you need about 200 clicks to get one sale total. But it all depends on the market and your potential income per sale.
With my event I know I didn’t have more than a few hundred invited. I only had one day to do it so that was all time allowed. And only 53 registered and only 10 showed up. But I just had another student tell me he has added over 1400 in a single day before Google blocked them and said they were at the limit.
I don’t think anyone quite knows exactly the number Google has set.. or if it is even the same for everyone. Sorry not more help on that one.
