Yahoo has more than a search engine

Probably they will continue working the same way, while the investment on web ads is surely going to grow in the future, and Google is a master at it.

Yahoo, on the other hand, has a lot of other different businesses to get revenue from, like upgrading your email account, fantasy football-like games, Yahoo Yellow Pages, or Yahoo for small businesses and, even though they might not be the leading search engine, they can still make revenue from other stuff.

Personally I’d be more comfortable buying Google because I can understand their business model better and I feel confident that their business will grow, while I can’t really understand all of Yahoo’s businesses, they are too much for me, the amateur finance enthusiast.
