Google recently launched a new match type for Beta Testing called Automatic Matching. The basis for this new matching “opt-in” is to help advertisers with limited keyword lists, that struggle to spend their allotted daily budgets, more effectively reach their daily spend caps. The way it works is, Google will analyze your current keyword list over a period of time and determine keywords they believe are relevant and closely related to your current keyword theme to find additional traffic for your campaign. In theory, it will work in a similar fashion to Google’s Content Network in which Google determines based on your keyword lists where you should have your ads placed within the Google Content Network. The bidding will be determined based on your current bidding strategies and will not exceed your Ad Group Default Bid. In the interface, you will simply see a line item that shows you an overall number of clicks, spend, etc… that the Automatic Matching generated for your campaign, much like you would see if you opted into the content network for your keyword targeting campaigns.
