What does it mean if a campaign state is stopped on Apsense?

The campaign is no longer active or running — either you paused it yourself, or APSense automatically stopped it (e.g., budget ended, time expired, or policy issue).

That means You have run out of credits or You got the amount of clicks You have ordered.

All campaigns are run only for 3 days.

Either campaign is expired our you have run out of credits

May be you violated the terms by using frame breakers and some one reported about it, otherwise the campaign is completed

maybe your campaign was completed . . . so you can promote again

wait for new campaign

It might be on pending status my friend :) just be patient.

campaign runs for only 3 or 4 days, mostly campaign ask for USA, UK AU traffic, if you not get any credit its mean your sharing link not get up to marks of advertiser, you should join worldwide campaign
