The Enterprise version of PopShops contain "power tools" for affiliates. In addition to everything in the Pro plan, with Enterprise you get:
If you have more than one ID in your affiliate accounts, you can create different profiles within PopShops. Click the Profiles button on the "Pop it in" tab and add as many affiliate IDs as you want.
Create your own subID-tracking parameters for each of your shops. Click the preferences button (located over the thumbnail images in ShopBuilder), then select the "Tracking with sub-accounts" tab.
With SEO rules you can add keywords and search-and-replace keywords words in your shops. For example, if you were optimizing a section of your site for "Father's Day gift idea" and wanted to add that phrase to the beginning of every description in your shop, you would start by clicking the SEO Rules button on the "Customize" tab. Then you would Add a new rule, give the rule a name, select "insert at beginning" in "item description", and lastly type "Father's Day gift idea" into the Keyword field. Once you click Save, your phrase will appear on every product description, even the ones in AutoFeed. Here is a quick screencast of the SEO rules in action.
Enterprise users can add a search box to their website and search across the merchants within their shops. This feature is available in the Preferences box within ShopBuilder.
You can create dynamic RSS and XML feeds from keywords limited to the merchants of your choice.
