Unlike Auction's current week-to-week bidding system. You bid a flat amount for each week of impressions. This means that there are always two winners that can advertise on the platform, and everyone else has to try again at a later point. Which can be annoying for users who want to grow their bots.
CPM Bidding is a new method we're trying out to allow more people to advertise. Instead of one winner per slot, we allow everyone to set a spending limit with their bid. Then we fall back to the next advertisement when the spending limit has been reached.
The highest bidder will always get the impressions first until they run out of budget. Then, the next highest bidder will receive the spot. This goes on until there are no more impressions or bids left.
How to read the bids
At a first glance, CPM $2.20 @ $200 might be complicated to read. What it means is $2.20 per thousand impressions with a spending limit of 200$.
How do I pay for my bids?
The current setup for tests is that you pay your estimated impressions at the start of the week. If you receive more impressions than previously estimated, we ask you to pay the additional amount afterwards, in the event of you receiving fewer impressions, you will receive the sum paid back in credit.
In the future, the aim is to allow users to top-up and dynamically pay for impressions while they are being shown.
For simplicity sake, the interface hasn't changed much. The largest change is that instead of one input, you now have two. One for the price per thousand impressions, and one for your budget.
