Attribution Models and Understanding SEO’s Role in Conversions

SEO often plays an early or supportive role in the customer journey, making it difficult to measure its true impact using traditional attribution models. Understanding attribution helps marketers properly value organic search within a broader digital strategy.

Attribution assigns credit to marketing channels that contribute to a conversion. Common attribution models include:
