So you have implemented every possible Google AdWords Ad extension from Social Extensions to Product Extensions, but have been unable to see if these add-ons are actually bringing in conversions to your site — until now. Google has added conversion tracking metrics to the Ad extensions tab of the User Interface.
To see conversions in the Ad extensions tab, select Customize Columns under the Columns drop down menu. Add these conversion metrics of your preference to your saved columns. See screen shot below.
Conversions metrics are available for the following Ad extensions: Location, Product, Social, Call, Offer and Sitelinks. Being able to see conversions associated with Ad extension clicks is a great way to see how different parts of your Pay-Per-Click (PPC) ad are performing.
The following screen shot shows you how many conversions resulted when a searcher used the Click-to-Call option of a PPC ad. It is interesting to see how many online conversions were made after a phone call was made.
In order to see how Ad extensions compare to your normal PPC ad, you must run a Click Type Segment report. However, in this report you will not be able to differentiate which Sitelink is performing since up four Sitelinks can be shown in one ad. Advertisers are still unable to test which Sitelink message is converting or even which message has the highest click-through rate.
