Launch by syndicating pay per conversion ads to publishers of all shapes and sizes (from blogs to the NYTimes).

Syndicate Snap SERPs and ads to niche verticals through Snap API. Make the index and algo easy for publishers to configure with a GUI.

Sneak a peek at Eurekster - make your algo self-sharpening with user data instead of just buying user data from ISPs. Make sure that the users who implement your API will have an algo unique to their community.

Partner with PreFound so that the Snap API syndicators can enable their users to add content to THEIR SERPs.

If you actually want to take on Google, Yahoo and MSN you will have to pour every penny of your revenues into research and development. Or pour it into AOL so you can win their Google search traffic ;)
