Verify every impression in programmatic guaranteed campaigns
Programmatic guaranteed commits your budget to fixed impression volumes from a named publisher at a negotiated price, but a signed deal does not guarantee clean traffic. Invalid impressions, viewability gaps, and audience delivery shortfalls can all erode the value of a guaranteed buy. Tapper holds every delivery to the standard you paid for.

Guaranteed does not mean verified, and delivery shortfalls are rarely caught without independent monitoring
Programmatic guaranteed deals are the closest the programmatic ecosystem comes to traditional direct IO buying. A fixed CPM, a committed impression volume, an agreed placement, and a named publisher make PG the premium tier of programmatic. But the mechanisms that make PG feel secure, the direct relationship, the signed deal, the committed inventory, do not independently verify that each impression delivered meets the specification agreed. Publishers can fulfill impression volume commitments with lower-quality placements from sub-properties, serve impressions at times or in contexts that do not reflect the audiences negotiated, or deliver against weaker viewability standards than were implied in the deal without your reporting system flagging the discrepancy.
Invalid traffic is a less severe problem in programmatic guaranteed than in open exchange, but it is not absent. Publishers with mixed traffic quality across their network can inadvertently or deliberately route PG impression delivery through placements that carry higher invalid traffic rates. Sophisticated bot networks operating through residential proxies can penetrate even curated PG inventory. Click stuffing and injected interactions are known to occur on premium publisher placements where advertiser attention and CPM levels are highest, precisely because the financial return per invalid interaction is greatest. Standard brand safety tools screen content but have no mechanism for verifying impression delivery quality at the individual event level.
The consequences of undetected delivery shortfalls in a programmatic guaranteed context are financial and strategic. If a PG campaign delivers 15 percent of its committed impressions through invalid traffic or misrepresented placements, you have overpaid for the deal relative to genuine delivery. If audience quality does not match what was negotiated, the CPM premium you paid for contextual targeting or audience segment access is not justified. Without independent impression-level monitoring, you have no basis for identifying where the deal underperformed or for holding the publisher accountable. Tapper provides the verification layer that turns a publisher's delivery confirmation into independently audited campaign performance data.
How Tapper protects your programmatic guaranteed on Display
Three steps from connection to clean campaign data, no engineering required.
01
Map your programmatic guaranteed deal parameters
Tapper integrates with your DSP and maps the specific placement, audience, and delivery specifications from your PG deal, creating a baseline against which every delivered impression is measured.
02
Every impression verified against deal specifications
Traffic quality analysis, placement verification, viewability signal monitoring, and audience consistency checks run on each impression delivered under the PG deal, flagging deviations from agreed specifications.
03
Delivery audit data provided for publisher accountability
Tapper generates a deal-level delivery audit showing the proportion of impressions that met agreed specifications, the breakdown of any invalid or non-conforming traffic, and the adjusted effective CPM based on verified delivery, giving you the data needed for publisher conversations and future deal negotiation.

Frequently asked questions
A signed PG deal commits a publisher to deliver a fixed volume of impressions at an agreed CPM and placement specification. It does not independently verify that each impression delivered meets that specification. Invalid traffic, sub-property delivery, and audience misrepresentation can all occur within a PG campaign without your DSP reporting system flagging the issue. Independent monitoring is the only way to confirm that what was delivered matches what was agreed.
The most common issues in PG campaigns are audience delivery discrepancies, where the traffic delivered does not match the audience segment negotiated, sub-property delivery, where impressions are fulfilled from lower-quality placements in the publisher's network rather than the specified placement, and sophisticated invalid traffic including click stuffing and residential proxy traffic. Outright bot traffic is less common in PG than in open exchange but is not absent, particularly on high-value placements where the return per invalid impression is greatest.
Tapper measures the proportion of PG impressions that meet agreed delivery specifications, including traffic quality, placement, and audience consistency. The adjusted effective CPM is calculated by dividing total deal spend by the number of verified, specification-conforming impressions. If 15 percent of delivered impressions fail quality checks, your adjusted CPM is approximately 18 percent higher than the negotiated rate, reflecting the genuine cost of the valid delivery you received.
Yes. Tapper generates impression-level delivery audit data that specifies which impressions failed quality checks, what the failure reason was, and the aggregate delivery shortfall as a percentage of committed volume. This data can be shared directly with publishers as the basis for shortfall claims, make-good requests, or CPM adjustments. Having independent third-party audit data rather than self-reported publisher data significantly strengthens your position in those conversations.
Yes. Programmatic guaranteed CPMs are typically the highest in the programmatic stack, reflecting premium placement and audience commitments. When invalid traffic or delivery discrepancies occur at those CPM levels, the absolute spend waste per invalid impression is greater than at open exchange or even PMP rates. A 10 percent invalid traffic rate on a $50 CPM PG deal costs five times as much per impression as the same rate on a $10 PMP deal.
Yes. Tapper provides real-time alerting when delivery quality falls below configurable thresholds during a live PG campaign. This allows you to raise delivery issues with the publisher while the campaign is running, rather than discovering shortfalls after the budget has been fully spent and the campaign has ended.
