Frequently Asked Questions
What is header bidding?
Header bidding is an auction that determines which ads serve when a webpage loads. Every ad “zone” has its own auction that happens whenever a page loads. Ads with higher bids are much more likely to serve.
What’s a cpm?
Cpm stands for “cost per mille.” (Mille is Latin for ‘thousand.’) So cpm means cost per thousand— the amount you’re willing to pay us to serve your ad one thousand times. The cpm for an ad is your “bid.” If you bid $50, this means you’re offering us $50 to serve your ad 1000 times. (A cpm of 50.)
Why isn’t my ad serving?
You probably didn’t bid enough. If your ad is facing other ads with higher bids, those ads are much more likely to serve. Your ad will serve eventually, but it could take awhile. If you want your ads to serve faster, bid more.
How do I track impressions?
After you login, hover over your email address in the top right corner. Select “Account” from the dropdown menu. Here you’ll see all your ads, along with their zone, total views, and cpm. For each ad, the amount we’ve deducted from your account balance is equal to its cpm times its total views, divided by 1000.
Is my deposit refundable?
All deposits are non-refundable.
Can I delete a bid?
Yes. After you login, hover over your email address in the top right corner. Select “Account” from the dropdown menu. Next to the bid you’d like to delete, press the “delete” button to the far right. (This action cannot be undone.)
How long will it take my ad to serve?
After you successfully submit a bid, we must approve your ad before it serves. This process happens very quickly. (Under an hour is common on business days.)
How is my account debited?
Your account balance is only debited when your ads actually serve—not when you submit your bid.
But in order to submit a bid, your account balance must be able to cover it. In other words, your balance must be at least as high as your bid times the number of impressions you’re bidding on, divided by 1000. For example, a bid of $75 and 5000 impressions requires at least $375 in your account ($75 x 5000/1000).
When your account balance reaches $0, all your ads instantly stop serving. When you deposit more money, they’ll instantly resume serving.
