I'm considering buying 300k impressions, but roughly how long would that last? I've got a contest running till the end of January and it'd be a waste to have the ad running till March XD

, it pretty much depends on how many other ads are running at the time but I feel pretty confident in saying there is no way it would last till March. Or past January. I would be really surprised if it would last through the end of the year.

Right, in that case I certainly needn't worry about buying too much :) Thank you!

[edit] Question answered, could either of you close this for me? Thanks in advance!

, just thought I would add that you can start out small and see how it goes. You can always add more impressions.

I've bought 2,500 impressions for 25 CSC a couple of times; they ran out within a day but I never got to clock within how many hours. 300k impressions (1,250 CSC) is cheapest :P I'll see how long these last and calculate how many more I need from there.
