In April 2013, Google announced plans to add enhanced campaigns for AdWords to aid with campaign management catered to multiple-device users. The enhanced campaigns aimed to include advanced reports about users. This move was controversial among advertisers.
In July 2016, Google unveiled "Showcase Shopping" ads. With this format, retailers can choose to have a series of images that appear in search results related to various search queries and keywords.
In October 2017, Google revised AdWords' daily budget caps, which were previously set at a maximum of 120% of preset daily budgets, to a maximum of 200%. This change was rolled out on the same day it was announced, prompting criticism from paid search professionals, though Google later clarified that this change would affect only short-term campaigns of less than 30 days and that for campaigns running more than 30 days, overage charges would be refunded.
