Attribution Models

Attribution models are frameworks used to determine how credit for sales and conversions is assigned to touchpoints in conversion paths. In the context of search engine optimization (SEO), attribution models help marketers understand how their organic search efforts contribute to the user’s journey and eventual conversion. Since a single customer may interact with multiple marketing channels before converting, attribution models provide insights that assist in optimizing strategies for higher ROI and better allocation of marketing resources.


There are several types of attribution models commonly used in SEO:

  1. Last Click: Assigns all credit to the final touchpoint before conversion, often undervaluing the contribution of other channels in the conversion path.
  2. First Click: Credits the initial touchpoint that introduced the customer to the brand, overlooking subsequent interactions.
  3. Linear: Distributes credit equally across all touchpoints in the conversion path, providing a more balanced view but potentially diluting the significance of key interactions.
  4. Time Decay: Gives more credit to touchpoints that occur closer in time to the conversion, assuming they have a greater impact on the decision.
  5. Position-Based (U-Shaped): Allocates a higher percentage of credit to the first and last touchpoint, with the remaining credit divided among the intermediate interactions.
  6. Data-Driven: Uses machine learning and historical data to attribute credit proportionally based on the actual influence each touchpoint had on the conversion process.

SEO considerations:

To effectively measure the impact of organic search on the customer journey, it is important to align the attribution model with the business’s objectives and desired outcomes. Consider the length and complexity of the conversion path when choosing a model, and regularly analyze data to identify trends and adjust the model accordingly. Integrating SEO data with other marketing channels can provide a comprehensive view of performance and help optimize the overall strategy for maximum impact.

Implementing the right attribution model allows SEO professionals to justify their work by proving the value of organic search in the context of a multi-channel marketing strategy. In turn, this can influence budgeting decisions and campaign adjustments to drive better results.
