Again like I mentioned before, always use the data feed. All else equal it seems to rank higher because you have the ability to do #1 below among others.
1. For the title of your site in setting up the data feed make sure to use your most appropriate keywords for your products as a whole, i.e...
"Bob's Purple Widgets."
If you don't use the data feed froogle will pick your domain as the site title.
2. For the name of each product you have ample leeway in naming the products. So be sure to cover all pluralisms and other word forms in the name, i.e....
"purple widget - purplish widgets" (or whatever) as another example, people could all use these same terms wanting the same thing...apple brownie, apple fritter brownies, brownie with apples, etc.
3. You can give a fairly lengthy product description (I don't remember the exact length). Make sure to accurately describe it with all the right keywords so your customers will find you. Wait, forget that, I'll go ahead and say the words....keyword stuffing seems to work.
A couple general thoughts. All you have to work with is text as tags and other goodies won't be there; you give them a delimited text file. So think keywords in site name, product name, and product description. Also, it appears that the froogle algo has very few variables...froogle is still a baby.
Hope that helps, not that anyone will bet much traffic anyway.
