Google Merchant Feed?

[jonhsame]

Hi

I have a good friend that has set up a Google Merchant Center account. I do seo/Google and Bing campaign management and he asked me to help him. He set up a Merchant Center account. I need to find where this feed originates in Magento. He is the only person I know using Magento so I have little knowledge about where to look for things like setting up a Merchant acciunt feed. He set up a Shopping  campaign in his adwords, and got his wrist slapped. All his adwords campaigns are on Paused because things are not being in the right category. If anyone can send me some info I would be most grateful.

Thanks in advance and have a great day!
