Move beyond last click attribution in Google AdWords

People often see many ads across different devices before making a purchase, booking a flight, or signing up for an account. Because of this, advertisers know that last click attribution may not always tell the full story. In 2014, we released the Attribution Modeling Tool in AdWords to share insights about how users interact with your ads. Later this month, you’ll be able to integrate the attribution model of your choice with your conversion data and bidding.

For each conversion type, use a simple drop-down menu in Conversion settings to select one of six different attribution models -- last click, first click, linear, time decay, position-based, or data driven. When you pick a new model, credit will be reassigned across the conversion path for all search or shopping ad clicks on, and your conversion stats will change moving forward. You can adjust bids based on your new way of counting conversions, and if you’re using automated bidding for search ads, your bids will be optimized automatically to reflect your new model.
