Comparison Shopping Engines are gold when it comes to product research. They’re filled with all the information you need to make your buying decision, especially if its the lowest price you’re after. Product feeds that adhere’s to specific data structures that Google, Yahoo, PriceGrabber, TheFind, etc is all you really need and they’ll do the rest; some are free like Google & Yahoo, but some are not like PriceGrabber and TheFind – Upload it and let it do it’s thing.

On Yahoo.com SERP, you’ll find a couple of unique features you can’t find on Google; “Ask a Friend”. Today, we got an online conversion from an organic visitor on Yahoo for the keyword, “Fluke Multimeter”. Here’s what I saw:

Notice the “Ask a Friend” beside the compare link with a Facebook icon next to it. When you click it, you get a popup window that prompts you to post asking your friends to comment what they recommend based on the first 4 product listings from the Yahoo Shopping results.

If your Facebook friends list includes someone in the same industry or uses the same tools or products as you, there’s a chance they may comment and recommend one of those products.

I think its a great example and definitely a first for a major search engine to integrate Facebook into SERP.

Great job Yahoo!
