Google has updated the AdWords Editor program to version 12.1 which brings many changes. New features include Expanded Dynamic Search ads, Shopping Showcase ads, and new bid options in the Advanced Bid Changes tool. Google wrote on Google+ “Version 12.1 of AdWords Editor now globally supports expanded Dynamic Search Ads, Shopping Showcase ads, and downloadable metrics for first position bid, ad relevancy, landing page experience and click-through-rate. Back in June, we also announced custom rules to help you check for changes that don’t align with your best practices. In this release, you can now more clearly view which campaigns and ad groups violate these best practices.”
