Does anyone have experience with outcomes on listing your products under grouped search results as opposed to separated out.  It seems that this can be easily accomplished by using a SKU that is different then others in the listing but I wonder if one ranks better over the other (it appears that grouped searched rank a bit higher).  It seems that it would be best to take into consideration the audience you are targeting and what their habits are, i.e. would they be more likely to click on the group searches and look for products that way or do they want to find a reputable brand and would more likely click on that.  Any help or thoughts would be appreciated as I am not really finding any information on this subject.
