Google today introduced some major changes to AdWords to both make it easier to manage campaigns across multiple screens and to enabled more "nuanced" bidding and targeting. There's a very complete discussion at Search Engine Land.
A cynic or skeptic would argue the changes are directed primarily at bringing more advertisers into mobile and bringing mobile revenues up for Google (although advertisers can effectively still opt out of mobile).
One of the major changes is that advertisers can now make mutiple bids ("bid adjustments") for a single ad based on variables such as device, location and time of day. Mobile bids will be set at desktop/PC levels -- mobile CPCs are lower than desktop CPCs -- and advertisers will have to actively reduce them if they want to bid less for mobile clicks.
Some may see this as "strong arm tactics" by Google to raise mobile search revenues. However the company believes it's simply adapting AdWords capabilities for a new multi-screen environment.
Below are some of the main bullets (slightly edited) from the Google Inside AdWords blog explaining the new features:
Bid adjustments: With bid adjustments, you can manage bids for your ads across devices, locations, time of day and more — all from a single campaign.
Example: A breakfast cafe wants to reach people nearby searching for "coffee" or "breakfast" on a smartphone. Using bid adjustments, with three simple entries, they can bid 25% higher for people searching a half-mile away, 20% lower for searches after 11am, and 50% higher for searches on smartphones. These bid adjustments can apply to all ads and all keywords in one single campaign.
Dynamic creative: People on the go or near your store may be looking for different things than someone sitting at their desk. With enhanced campaigns, you’ll show ads across devices with the right ad text, sitelink, app or extension, without having to edit each campaign for every possible combination of devices, location and time of day.
Example: A national retailer with both physical locations and a website can show ads with click-to-call and location extensions for people searching on their smartphones, while showing an ad for their e-commerce website to people searching on a PC — all within a single campaign.
New conversion metrics: Potential customers may see your ad and download your app, or they may call you. It’s been hard for marketers to easily measure and compare these interactions. To help you measure the full value of your campaigns, enhanced campaigns enables you to easily count calls and app downloads as conversions in your AdWords reports.
Example: You can count phone calls of 60 seconds or longer that result from a click-to-call ad as a conversion in your AdWords reports, and compare them to other conversions like leads, sales and downloads.
All of these enhancements are designed to make search advertising both easier and more effective for marketers in a larger, more fragmented device universe. By the same token Google is trying to generate more money from its mobile advertisers and clicks, something it has struggled somewhat to do.
In its last quarterly earnings Google reported that average CPCs decreased 6 percent vs. Q4 2011 (attributable almost exclusively to mobile).
