Google announced that advertisers using AdWords will soon be able to adjust their bids based on a last click attribution model. Google said advertisers will be able to select from six different attribution models.
The six attribution models include last click, first click, linear, time decay, position-based, or data driven.
Here is a screen shot:
Google added, "when you pick a new model, credit will be reassigned across the conversion path for all search or shopping ad clicks on Google.com, 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."
This is launching "later this month" for AdWords advertisers.
