Hi i want to know that i start showing my ads byt please tell me how i closed to show them because i have limited money please tell me how
where are option and if i have to contact Google how much time is taken to closed
please reply soon

 

Pause the campaign.
That's it - the campaign stops showing amd you're not charged anymore.(Bearing in mind there is a time lag in reporting of up to 3 hours)
To be absolutely sure, delete the campaign.
But it shouldn't be an issue anyway in terms of 'limited money' , as you set the budget in the first place and set the time scale. If you only want to pay $500 for one month - then set the campaign budget for that and the campaign to end after a month

 

thanks to share very helpful information

 

1) Pause the campaign
2) Delete the campaign
