Google has now added the ability for its users to create their own search engine. Your ready made search engine will only pull search results from sites that you choose. Possible use could be for multisite search from your network of sites or searching of your favorite sites.

“This isn’t new – Rollyo, Eurekster and Yahoo already have similar products. But Google is also offering, as an option, to bundle the service with Google Adsense ads and share revenue with websites that embed the custom search engine into their site. Only Eurekster currently shares revenue with users. Yahoo’s product, which got a lot of press at launch, has barely been mentioned in the nearly three months since then.” ~ Michael Arrington
