Part III: Proof of Performance (POP)

Media planners and buyers spend hours, days, weeks and sometimes months, crafting and planning the perfect buy to maximize impressions within a client’s given budget. It is important to monitor the buy to ensure the plan matches the reality and you get what you paid for. Some advertising mediums are easier than others to monitor and measure effectiveness.

Generally, Out of Home (OOH) advertising is the most difficult form of advertising to measure effectiveness. It is hard to determine the actual impact of the billboard or how many people saw it. For these reasons, it is extremely important that media buyers require proof of performance for all out of home advertising purchases. At A3 Media, we believe a well-thought-out buy deserves effective post-buy monitoring to ensure the buy runs as designed, that is why we require and review proof of performance reports for all out of home advertising.

Proof of Performance, also known as POPs, is a certificate sent to advertisers by the outdoor vendor that contracted services were rendered. POPs reports, usually include the vendor and advertiser name, installation date, flight dates, photos of the actual ad on the specified board, and in the case of digital spots, number of times played. POP reports are usually required from large and national advertisers/agencies, but because of the important role they play, they should not be overlooked by regional media companies and advertisers.  

Requiring proof of performance is one way to ensure that the advertising plan matches the reality of the delivery. As soon as the contracts are signed, our traffic team confirms creative and flight dates with the out of home company. Then, once the posting period begins, photo proof of installation is required. These photos serve several purposes. 

  • One, they confirm that the billboard or other out of home advertising was installed on time.  This may be extremely important if your campaign is of a time sensitive nature. If installation was delayed beyond acceptable or contracted terms, then request the posting period be extended to compensate for the delay.  
  • Two, the photos will show actual visibility. Many out of home companies will provide the billboard’s ‘glamour’ shots during the contract process. These glamour shots are designed to show the billboard in the best possible way. Some of these glamour shots might be outdated.  The POPs photos will bring to light visibility issues including obstructions like taller trees, or poor lighting.   
  • Three, the POP photos will confirm the correct creative spot is posted in the correct location. Often, out of home advertising campaigns include multiple creative pieces which are specifically geographically placed for greatest impact. Despite previous confirmations, installation mistakes can happen. It is important to confirm that the out of home advertising is installed where it was planned.

There is an added element to Proof of Performance required when digital advertising is part of your advertising plan. At the end of posting period, the OOH vendor needs to provide a digital play report for agency or advertiser review. The digital play report should summarize the number of times your ad(s) was shown on the billboard (or other structure). If you have multiple creative spots running, the digital play report should include the number of ads shown for each creative spot so traffic rotation can be verified.

Whether you use a service or verify internally, it is important to monitor and require Proof of Performance and Proof of Play Digital reports for every out-of-home advertising campaign to ensure that the media plan is delivered correctly. Do not hesitate to ask for POPs from your vendor, Proof of Performance should be stipulated in the contract and verified prior to invoice payment. 

Effectively monitoring Proof of Performance is one way to ensure that the planned buy is executed as designed. Without regular observation adjusting the buy is impossible and the monetary investment as well as the time planning and strategizing for a successful campaign is wasted.

Part II: Tracking Rotation

Previously, I discussed the importance of checking pacing, a.k.a daily impression delivery (see blog post here), as part of the overall post buy monitoring process. Another part of this process that should not be ignored is trafficking instruction confirmation and creative rotation verification.

The creative and media teams often join forces to craft a complete strategy that delivers multiple creative assets to the maximum benefit for the client. Trafficking is the execution of the planned creative spots and often involves rotating said spots. Basically, rotation is determining the mix of multiple creative assets across an advertising medium. Sometimes rotation is simply spreading multiple creative spots out evenly. For example, spot A and spot B run evenly 50/50 throughout the entire flight or campaign. Other times, rotation is a more complex plan, involving many different creative assets, with different delivery goals and/or over different flight dates. For example, spot A and spot B run 60/40 for the first 3 weeks, then spot B and spot C run 40/60 for the next 6 weeks. As an agency, we never want to be in a position where the vendor does not execute our plan correctly.  

Communicating the trafficking instructions to each vendor is key. One of the first steps we do on every buy is to have a conversation with our AE to ensure that all creative assets were received, and traffic instructions are understood. Nothing is left to assumption and a simple email and/or phone call often ‘sets the campaign off on the right path’ and avoids much turmoil later.  

Once the campaign begins, it is important to check that the proper creative rotation is executed. Monitoring should begin as soon as possible to make sure spot(s) are delivered as instructed and, if required, any necessary changes are promptly made.  From there weekly checking may be necessary to ensure the instructions are being followed or corrective action occurs. Also, anytime the trafficking instructions change, a follow-up conversation with the AE and resumption of the monitoring process like it is a new buy is necessary.

So how is rotation checked? Sometimes, the creative rotation information is available from your vendor’s dashboard, but often, data this granular is not readily available. Do not be reluctant to ask your vendor to provide more information! On numerous occasions, I’ve noticed that even though everything looks good on the surface (i.e., pacing and impressions are good), when you dig deeper you find that your creative rotations are “off”. This is especially true when the campaign is targeting multiple DMAs. The rotation might be fine in one DMA but completely wrong in another. That is why it is important to sift through the data and examine it from various angles. It is often in this process that we find that human error is responsible for the error in rotation instructions. Had we not monitored this information from the beginning, we may never uncover that the trafficking instructions were not followed.

If you determine that the trafficking instructions were not followed and rotation is not as it should be, a conversation with the vendor is required. A new rotation plan, which sometimes may include makegoods from the vendor, needs to be developed and implement to ensure the initial plan is completed as designed.

Effectively monitoring rotation is one way to ensure that the planned buy is executed as designed. Without regular observation, taking corrective action is impossible and the monetary investment as well as the time planning and strategizing for a successful campaign is wasted. At A3 Media we believe a well-thought-out buy deserves effective post-buy monitoring to ensure the buy runs as designed which is why we investigate delivery reports with a fine tooth comb.
