Campaign Monitor is a San-Francisco based email marketing agency. To improve their PPC campaigns, they made a hypothesis:

If we match copy on a landing page dynamically with the exact verb used as a keyword in someone’s original search query, we imagine we’ll achieve higher perceived relevance for a visitor and (thereby) a greater chance of conversion.

In other words, the agency wondered whether the precise verb someone uses in their Google search has an effect on how they perceive doing something with a product, and—if they were to see this exact same verb on the landing page— whether this would increase conversions.

In the case of email marketing, for example, if a prospect typed: “design on-brand emails” into Google, ‘design’ is the exact verb they’d see in the headline and CTAs on the resulting landing page (vs. ‘build’ or ‘create’, or another alternative). The agency wanted to carry through the exact verb no matter what the prospect typed into the search bar for relevance, but outside the verb the rest of the headline would stay the same.

Their A/B tests concluded that dynamic copy swap actually increases conversions by 31%.
