At Yahoo! I worked within the Cost-per-Lead (CPL) group and focused on lead generation, performance marketing, and brand advertising primarily for the finance and mortgage industries.
Concept here was to grab potential customers attention using engaging portraits from U.S. currency which would be familiar to customers and relevant to the subject of getting a loan. Each banner ad showed a different portrait which was then echoed on the landing page along with the messaging when uses they clicked-through.
