Enhance Interactive (formerly ah-ha.com) offers paid listings, paid inclusion, banners and other contextual ads, and processes more than 1.5 billion search queries per month. Enhance's distribution network includes Excite, MSN and NetZero. Enhance requires $50 to open an account, and bids for keyword listings start at 3 cents. Enhance's logo link features, banner ads and low bid prices are great features, but their lack of a marquis distribution partner mitigate their impact, as will the fact that some of Enhance's keywords have been known to receive lower-quality visitors.
