Facebook ads, how long will it run for?

[Jake]

A good ctr for Facebook ads would be .15% or higher or 1 click per 666 impressions, some acceptable ads might require more than twice the number of impressions per click.

Typically they give you a couple of thousands impressions at the start to measure your click through rate, if it is low and the bid is low they will start slowing down the impressions.

That's an insanely low bid, only successful campaigns with high conversion rates are usually able to get click prices under 10 cents.

Usually one should bid CPC at least 1/2 of the recommended bid price.

Low bids will get impressions on more undesirable locations, like inside of game pages.

Hopefully you have defined a target demographic age range and perhaps profile interests.
