Prebid Server Premium health analytics report

When values of a metric are displayed as percentages in the UI, they will be displayed as decimals when you export the report.

Column Description
Average Clear Price The sum of bid price for delivered impressions divided by the number of bid requests sent.
Average Response Time The average time demand partners took to respond to bid requests.
Bid Requests Sent The number of requests sent from Prebid Server Premium to demand partners.
Bid Responses Received The number of bid responses received by Prebid Server Premium from demand partners.
Bids Submitted to Ad Server The number of ad requests that had a valid Prebid bid that was not subject to any additional Microsoft Advertising rejections returned to the ad server. This number is counted after the Microsoft Advertising auction process that evaluates bids received from all sources. The reduced volume between Valid Bids on Imps and this metric could be due to creative requirements not being met, being outbid by other bidders, or due to the option to send only the top bid back to the ad server.
Errors The number of errors in bid responses from demand partners.
Errors Rate The number of bid errors divided by the number of bid requests sent to demand partners.
Imps (delivered) The number of impressions successfully delivered and ads rendered. Note this report is based on sample log data multiplied to estimate the full volume of PSP activity and does not represent final delivery.
No Bid Rate The number of times demand partners did not bid divided by the number of bid requests sent to demand partners.
No Bids The number of times demand partners did not bid on a request. This does not include bid errors.
Total Bid Price The sum of the bid values received from demand partners.
Total Buyer Spend The media cost to buyers of impressions delivered.

Note: This report is based on sample log data multiplied to estimate full volume of PSP activity and does not represent final delivery.
User Matched Requests The number of requests where a user identifier was present. Note this metric currently only includes cookies for web and mobile web.
User Matched Requests Rate The number of user matched requests divided by the number of bid requests sent to demand partners.
Valid Bids On Impression Rate The number of valid bids divided by the number of bid requests sent to demand partners.
Valid Bids On Imps The number of bids received from demand partners that do not trigger errors, have a creative ID, and have a bid above $0. There may be multiple bids counted for each auction when multiple demand partners return bids.
Win Rate This metric should only be used with the demand partner dimension applied. It represents the percentage of impressions delivered by a demand partner relative to the total bid responses received. The calculation involves dividing the number of impressions delivered by the demand partner by the total number of bid responses received.

Error types

Code Error Description Remedy
0 NONE No error. None needed.
1 INTERNAL There is a server-side error from Demand Partner, such as a 400 status code. Seller should work with Microsoft Advertising to collect a specific example code to share with Demand Partner for investigation.
2 TIMEOUT Demand Partner did not respond within the timeout limit. Either increase timeout settings to allow for a longer response time or contact Demand Partner to inform them of the restriction. For more information on timeouts, see Add or Edit PSP Global Settings.
3 CLIENT Demand Partner's Prebid Server adapter generated an error. For significant quantities of this error type, Seller should contact Microsoft Advertising support to diagnose issues by looking at the internal Microsoft Advertising logs. An example of this error could be that video supply has been sent to an adapter that does not support it.
4 PARSE Demand Partner has formatted the bid response incorrectly. Seller should work with Microsoft Advertising and Demand Partner to determine and resolve the specific formatting issue.
21 NO_BID_PRICE No price received from Demand Partner. Seller should notify Demand Partner of the issue.
22 NO_CREATIVE_ID No creative ID received from Demand Partner. Seller should notify Demand Partner of the issue.
23 NEC_ERROR The bid was rejected during the Microsoft Advertising auction process. The bid was successfully received from Demand Partner, but the bid was rejected within the Microsoft Advertising auction. Seller can use the seller bid error report to diagnose specific rejections occurring on their supply.
24 CREATIVE_WRONG_SIZE Demand Partner is bidding with a creative size that doesn't match the tag size. Seller should review the creative size and notify Demand Partner regarding the mismatch.
70 MEMBER_NOT_ELIGIBLE Seller's settings are blocking the Buyer's member from participating in the auction. Seller should notify the buyer that they are currently blocked from bidding.
84 CATEGORY_REQ_ALLOWLIST The category of the creative is sensitive and requires addition to the allowlist. Seller should work with Buyer to determine if the creative warrants addition to the allowlist.
132 DYN_CREATIVE_INCOMPATIBLE_TYPE Dynamic ad-markup bidding is not supported for certain PSP demand partners that require client-side rendering when a Seller doesn't support it. Seller should correct their setup to align with client-side rendering requirements, on both supply and PSP sides.
150 SELLER_MEMBER_NO_CONTRACT Seller's contract isn't set up properly. Seller should work with Microsoft Advertising to remedy the contract issue.

To run your report

Follow these steps to run your report.

  1. Select Reporting from the appropriate top menu (depending on how your account has been configured).

    Or, from the Publishers top menu, click on Prebid Server Premium > Analytics > Prebid Health Analytics

  2. Select the relevant report from the list. The Report screen shows the available filters, dimensions, and delivery options for the report. The selections you make here will determine what report data is delivered to you, and how.


    For an explanation of how grouping and filtering work, see Dimensions, Metrics, Filtering, and Grouping.

  3. Select the relevant filters to limit the data displayed to just the information you want. For example, rather than running a report that shows impressions for all inventory sources, you may want to list results for just a select few. When you select a filter (by clicking Edit), a selection panel appears. Select items in the Available list (left), then click Add to include them in the Chosen list (right).

  4. Group by Dimension. Grouping allows you to display rows of data in the order you prefer.


    The more dimensions you group by, the larger the data set that is returned. Larger data sets can take substantially longer to process. Be sure to group using only the dimensions you need.

  5. Choose a delivery option. Once you've selected your filters and grouped by your chosen dimensions, you need to choose a delivery method. Available delivery methods include:
