Attribution (marketing)

Attribution is the process of identifying a set of user actions (“events”) that contribute in some manner to a desired outcome, and then assigning a value to each of these events.^[1][2] Marketing attribution provides a level of understanding of what combination of events influence individuals to engage in a desired behavior, typically referred to as a conversion.^[1][2]

History

The roots of marketing attribution can be traced to Attribution Theory, developed by Fritz Heider.^[2][3] By most accounts, the current application of attribution theory in marketing was spurred by the transition of advertising spending from traditional, offline ads to digital media and the expansion of data available through digital channels such as paid- and organic-search, display, and email marketing.^[2][4]

Concept

The purpose of marketing attribution is to quantify the influence each advertising impression has on a consumer’s decision to make a purchase decision, or convert.^[4] Visibility into what influences the audience, when and to what extent, allows marketers to optimize media spend for conversions and compare the value of different marketing channels, including paid and organic search, email, affiliate marketing, display ads, social media and more.^[2] Understanding the entire conversion path across the whole marketing mix eliminates the accuracy challenge of analyzing data from siloed channels. Typically, attribution data is used by marketers to plan future ad campaigns by analyzing which media placements (ads) were the most cost-effective as determined by metrics such as effective cost per action (eCPA).^[2]

Attribution models

Resulting from the disruption created by the rapid growth of online advertising over the last ten years, marketing organizations have access to significantly more data to track effectiveness and ROI. This change has impacted how marketers measure the effectiveness of advertisements, as well as the development of new metrics such as Cost per click (CPC), Cost per thousand impressions (CPM), Cost per action/acquisition (CPA) and click-through conversion. Additionally, multiple attribution models have evolved over time as the proliferation of digital devices and tremendous growth in data available have pushed the development of attribution technology.

• Single Source Attribution (also Single Touch Attribution) models assign all the credit to one event, such as the last click, the first click or the last channel to show an ad (post view). Simple or last-click attribution is widely considered as less accurate [Google] than alternative forms of attribution as it fails to account for all contributing factors that led to a desired outcome.^[2][5]
• Fractional Attribution includes equal weights, customer credit and U-curve models.^[2][4] Equal weight models give the same amount of credit to the entire media mix, customer credit uses past experience and sometimes simply guesswork to allocate credit, and the U-curve assigns all the credit to the first and last touch, discounting what happens in the middle of the conversion path.^[5]
• Algorithmic or Probabilistic Attribution uses science, usually proprietary algorithms, to assign conversion credit across all touch points preceding the conversion, using automated computation to decide where credit is due.^[5][6] Algorithmic attribution starts at the event level and analyzes both converting and non-converting paths across all channels.^[4][6] Weights are then combined by grouping such as placement, site or channel as reporting granularity is decreased, allowing the data to point out the hidden correlations and insights within marketing efforts.^[2][6]

Interactive and Cross-Channel Attribution

Interactive Attribution refers to the measurement of digital channels only, while Cross-channel Attribution refers to the measurement of both online and offline channels.^[6]
