First Look impressions are grouped with Ad Exchange metrics (for example, "Ad Exchange impressions" and "Ad Exchange revenue"), but are mostly represented by default values for dimensions related to creatives and line items, as First Look does not need an Ad Exchange line item to deliver impressions. Because of this, you may notice a dash ("-") instead of a name in these reports. The dashes are also exposed in the Ad Manager API.
Other default values include "0x0" for creative size, and "Unknown" for creative type.
Data Transfer uses the default value "" (null string) in First Look reports. Relevant impressions appear with the value "First Look" in the "Product" field.
Your overall fill rate in Ad Exchange may appear lower after enabling First Look. This is because of the lower fill rate associated with First Look, as well as the additional requests it contributes (that is, Ad Exchange is called even when it normally wouldn't have priority as part of dynamic allocation). This should have little impact on fill rate for your unified pricing rules.
To view fill rate for Open Auctions or First Look only, you can filter the "First Look" transaction type from your reports.
To get a more accurate report on fill rate, you may wish to exclude non-standard ad sizes for which First Look does not serve, such as 1x1 pixels. As an alternative, you can also block these ad sizes from the First Look rule set up above.
