How much impression is good for testing?

[pk7677]

I'm talking about Facebook right now, let say If my ad is running 4k imps with a ctr 0.02 should I ditch it and move on with other well performing ads? or should I wait a while for more impression see if the CTR increase or not?

Currently my highest CTR ad is 0.057% don't know if I should tweak it or just start making some new ads. Any suggestions?

i always run my ad's until 10k imps to get a baseline.

also make sure to run at peak hours for consistent stats. ( 4pm-9pm )

lower bids if your ctr approaches 0.1% so you can keep testing other ad's evenly.

4k imps is too early to tell for the 0.02, one quick click can boost that considerably.

try putting borders around ur ad's.

good luck, have fun.
