Proposed Definition of an Ad Viewthrough

Viewthrough (view-through) is a measure of the passive but self-directed response from paid media (banner, rich media, video or audio). For starters:
  • Scope
    • Post-impression viewthrough follows from one or more ad exposures where there was no click event
    • Although the focus here is on display media, viewthrough or passive response could come from email, affiliate advertising, online PR and "dark" social media
    • Apart from Google's self-serving studies, no independent research validates the notion of a paid search viewthrough
  • Relation to Clickthrough
    • Distinguished from post-click visitation or conversion
  • Measurement
    • Can be a success metric like a conversion, high-value task or a site visit
    • Can be measured by a brand on its' own Web properties through site analytics
    • Can be measured more broadly (competitor/peer site visitation, search, etc...) through panel-based research
    • May be subject to attribution rules, such as first touch, last touch, equal touch or staistically derived techniques
  • Time
    • Is subject to a lookback and lookahead window that is configured by the ad server
    • Viewthrough impact decays over time from the initial ad exposure
  • Calculation
    • The VTR (viewthrough rate) is calculated as # of viewthrough / # of impressions (viewed impressions preferably)
    • Impressions should be based on "viewed" or "viewable" for most accurate measurement
    • In-flight viewthrough are observed during a live ad campaign, while the post-flight viewthrough "vapor-trail" can be observed when the campaign ends or is paused

  1. The digital advertising display is one of the best way to describe the products and its USP. It is widely implementing in the advertising agency because it is easy to use and enhance the beauty.
