Related to my last post about Using Google Product Extension Ads, I’ve already been asked several times what feed goes where and what ads belong to what Google services.  Brian Smith, who writes ComparisonEngines.com wrote a good post explaining The Importance of the Google Merchant Center Data Feed which I recommend you read for further clarification.

Below is a real life example of a Google search results page for the keyword “dog training collar”.

The Google Product Search listings come from your data feed that is submitted to your Google Merchant Center account (formerly called Google Base). There is no fee associated with clicks on these links (or the underlying shopping pages).

The Google Affiliate Network listings come from you guessed it, the Google Affiliate Network (formerly Performics). Merchants cannot control these ads, as Google is the publisher and is earning a fee from the advertiser.

The Google Product Extension ads (as covered in my previous post) are created by connecting your AdWords account with your Google Merchant Center account.

If you’re still confused, comment below and I’ll help answer your question.
