Google product XML feed is a file with detailed information about the products. Feeds can be created according to the RSS 2.0 specification using the Google Merchant Center namespace.

You need a product feed if you are a merchant with an eCommerce store and want to get your products into search results, dynamic ads, price comparison websites, or partner networks. Product feed supply your product data to those online sale channels so that buyers can easily find your products anywhere.

According to the RSS 2.0 specification, each data item has three predefined attributes: title, link, and description. All of these items are required when creating a product feed.

Syntax:
    <channel>
        <title>Feed Title (String)</title>
        <link>Website URL</link>
        <description>Feed Description (String)</description>
        ...
            <item>...</item>
        ...
    </channel>

The data feed also requires image_link, price, id, condition, availability attributes. With their help, Google Merchant Center and Google AdWords Services provide the necessary information about the product.
