Google will automatically switch all Adwords campaigns to ‘enhanced’ on 22-July-2013. If you don’t do it before then, Google will do it for you. And you can be confident they will be thinking of their interests, rather than yours. The changes are mostly bad news for those of us that sell software for desktop computers. In particular you can no longer choose not to bid for clicks on tablet devices. I would like to have more control over how I bid on different platforms, not less, so I am not happy about the changes. However your choices are either to upgrade your campaigns to ‘enhanced’ or close your Adwords account.
You can at least bid less for clicks on mobile devices. If you are selling downloadable software that doesn’t run on mobile devices, I recommend you set your bid adjustment much lower for mobile devices. My own analytics data tells me that mobile devices only have one tenth the (measurable) conversion rate of desktop/laptop computers. So I have set my mobile bid adjustment at -90% for mobile devices. Presumably you can set it to -100% if you don’t want to bid for mobile clicks at all. I don’t understand why advertisers aren’t being given the same option for tablet devices.
Note that you can’t set a mobile bid adjustment for CPA campaigns. However Google should notice the lack of downloads and sales on mobile devices and adjust the mobile bids down for you automatically.
Upgrading is pretty straight forward and should only take a few minutes. More details on the software promotions blog.
