Just like Overture and Google AdWords, business at LookSmart is moving pretty good too. LookSmart offers pay per click advertising at $0.15 per click. With the LookSmart Small Business Listings, you can submit one URL to the LookSmart directory for a fee of what is usually around $49.00 unless you get a promotional discount. If your content is approved, and most listings are, your site will be placed in the LookSmart directory. Within a day or two it will be syndicated across the LookSmart syndication network.
MSN is currently the largest and most important syndication partner of LookSmart and 90% or more of the traffic you will receive from the LookSmart network will come from MSN. The main difference between pay per click advertising on LookSmart and other programs like Google AdWords is the flat $0.15 rate per click and the fact that you cannot buy specific placements for specific keywords (Google Adwords use fluctuating rates). If you utilize the LookSmart pay per click program you will be subject to a $15.00 monthly minimum spend. LookSmart creates special offers that lets small businesses to submit up to 5 pages from a website.
In addition to the major programs that are mentioned above there are shopping search engines like that will also offer pay per click programs for product listings, which is smaller pay per click engines. There are literally hundreds of other pay per click search engines out there. iGetNet keywords is another program that chances are, you have never heard of. You've probably gotten email Spam from someone trying to sell IGN keywords or a phone call from a sales rep that is trying to sell you this product. While it's not a pay per click program, it is a source of confusion for many new to keyword marketing. I would suggest that you leave these people alone because you will likely get more than you bargained for here or not enough.
