Verification Overview

The Verification Suite is a premium data set that provides a window into the type of environments where your ads were seen, ultimately enabling you to confirm whether your ads were delivered according to your expectations.

Verification includes the following features:

  • Display Verification: Verification categories provide insight into where ads appeared, such as pages, domains, geo, and viewability.

  • Video Verification: Video verification includes content, quality, and safety measurements for player-level data.

  • Viewability (Display and Video): Viewability measures where the ads appear on the page.

Sizmek Advertising Suite Verification enables you to use either a dashboard or Excel reports to measure and improve the quality of your media buy. You can access the Verification dashboard through the Visual Analytics menu.

Importance of Verification

Verification is critical, considering the evolution of digital media:

  • More sophisticated bot traffic means that advertisers are at greater risk for wasting money on ads that do not appear on real sites.

  • Proliferation of network and exchange buying has brought with it a great deal of low-quality inventory that could be unsafe for brands.

  • Industry focus on viewability standards adds pressure to ensure that ads can be seen by their target audience.

Verification ensures that your campaign meets expectations:

  • Safeguard your brandfrom appearing alongside objectionable or misaligned content.

  • Gain insights for planning, based on the types of inventory which perform best - by channel, content, geography, and device type.

  • Negotiate improved placement with publishers using unbiased independent data.

  • Reduce waste by optimizing for placements that match your message, and get results. If your ad is not running in the environment you intended, it is, at least, partially wasted.

How does Contextual Verification Work?

When Verification is enabled for a campaign, Sizmek sends the URL for the page on which an ad appears to the Peer39 contextual data engine. Peer39 grabs the page content and processes it using its classifier that analyzes the page content and classifies it with one or more contextual, safety, video, or fraud categories. Finally, Sizmek combines Peer39 verification data points with campaign delivery data metrics from the Sizmek ad server in a single location within Sizmek Advertising Suite Analytics.

Peer39 can analyze page content in twelve languages - English, Spanish, French, German, Portuguese, Dutch, Italian, Chinese, Japanese, Turkish, Polish, and Russian - and identify 40 languages.

The following diagram shows how Sizmek and Peer39 verify the content of the pages on which your campaign's ads appear.


Peer39 categorization is a hybrid between page-based and domain-based categorization. The Peer39 contextual categories algorithm primarily looks at the content of the specific page and classifies it with the most relevant content category. The page level classification is not necessarily based on the general domain topic, but rather on the topic of the specific page within the site. Peer39 also categorizes a page with a category that is appropriate for the domain topic. For example, a page within Ebay that has a product for home décor could be classified as Home and Garden, Home and Garden > Decorating, and Shopping.

Important: Contextual verification can categorize a page in more than one context. For example, a page can include an ad above-the-fold, sports, and mature content. The platform can record a single impression under more than one content, video player, language, or negative content category. Adding up the number or percentage of impressions for more than one content category does not result in a meaningful or accurate figure. For example, if the data in the Verification dashboard shows 10,000 impressions (15%) for the Science category and 10,000 impressions (15%) for the Food and Drink category, it does not mean that the platform served 20,000 impressions or that those two categories equal 30% of the total impressions.
