To ensure that Google sends you the most appropriate impression calls, you
can pretarget impressions to receive requests for only the impressions
that match your targeting criteria by using one of the following:
The quota system manages quota by these four locations (see Trading
Locations under Peering for
details):
North America (East Coast)
North America (West Coast)
Europe
Asia Pacific
In each trading location you can define multiple bidding endpoints (up to
8), each identified by a URL (for example,
http://us-east.my_bidder.com:1234/google_rtb) to which Authorized
Buyers sends bid requests. Each bidding endpoint has its own callout limit (in
callouts per second)—you can configure the endpoints and their limits by
contacting your technical account manager or through the Buyer
API.
The quota system guarantees that an endpoint does not get more callouts than
its callout limit. If in a trading location where there are less pretargeted
impressions than the total endpoint capacity, the quota system balances the
callouts among the endpoints. The quota system also implements error
throttling—if an endpoint has high callout error rate, the system
lightens its load by enforcing a stricter callout limit than the configured
one. If there is spare capacity in other endpoints in the same trading
location, error throttling will cause the callouts to shift to them; otherwise
the excess pretargeted impressions will be dropped.
Because quota management comes after pretargeting, it does not affect the
total number of pretargeted impressions in a trading location. It can only
shift callouts among endpoints in the same trading location, or drop excess
pretargeted impressions if the callout capacity is exhausted.
