Emptypockets is saying what I have said 100 times in various threads if you want traffic raise your budget up. Test it yourself. Roll out the same ad 3 times. One with your $150 budget, 1 with $1000 budget and one with $50,000 budget. Almost always you will get immediate impressions on your bigger budgets.
Actually, the budget setting doesn't even remotely affect impressions anymore.
I always start my campaigns with a $20.000 or $100.000 budget from the very beginning - but this has ZERO effect on impressions. Nada.
Try it yourself; Start a campaign with $1000, wait for FB to not give you any impressions, or maybe a handful (which seems to be their new way of working).
Then, jack up the budget to $10k or even $100k. See a dramatic increase in impressions now?
Didn't think so.
