Google was born in 1998 after developing ‘PageRank’ that checks the quality of inbound links instead of the number of inbound links as well as taking ito account the type of fonts used in the page, subdivisions and the location of each word and the content of similar web pages. Google has become aggressive when it comes to elimination of spam used in black hat search engine optimisation (SEO) techniques. With Google’s paid Adwords advertising you can customize your own advertisements by allowing you to choose your keywords to direct where your advertisement displays. Google implements cost-per-click pricing, so you only pay when users click on your ad.
Google maintains its own spider based index and its revenue comes from adwords and adsence. Google also has a free directory that is powered by the popular Open Directory DMOZ. Google is currently trying to break into the mobile phone market with its operating system ‘Android’.

Yahoo originated in 1994 by Stanford student Jerry Yang who created a website named “Jerry’s Guide to the World Wide Web.” This is a precursor of yahoo directory which was a manually generated list of websites organised in a hierarchy rather than a searchable index. It is the second most used search engine. Yahoo’s directory requires evaluation by human editors and yearly payment but remains popular because it is difficult to spam with black hat seo techniques like doorway sites which can still get past google spam filters.
