Methods and systems for determining a correlation between an online campaign and offline activity may include generating a content item and content identifier data identifying the content item, transmitting the content item and content identifier data over a network to a client computer, wherein the content item or content identifier data is configured to cause the client computer to display the content item on a resource and to emit a first signal based on the content identifier data, receiving an indication that the content identifier data was received at the time of a transaction by a user at a point of sale terminal, and determining a correlation between presentation of the content item and the transaction based on the generated content identifier data and the received content identifier data. |
