Google announced this week that it is offering marketers more tools in its AdWords Opportunities tab.

One of the new features includes more statistics for keyword ideas. AdWords used to offer "estimated monthly searches" for keywords that marketers aimed to use in paid search campaigns. Now, the toolbar will also show insight on impression estimates, costs and clicks for various key phrases. The goal is to help marketers make more informed decisions about which keywords will drive the best performance.

Additionally, AdWords will now provide first-page CPC ideas to improve the chances that users' ads will appear within the first page of search results. This could be especially important, as online holiday purchase trends suggest consumers pay attention to the paid search ads that appear in results for their shopping-related queries.

The new tool may come in handy for a number of companies in the coming year; as eMarketer reported, U.S. advertisers are expected to spend $13.59 billion on paid search in 2011.
