Difference between Google Yahoo Bing

Google is strongly associated with simplicity, usefulness, pages that load fast and Yahoo is connected with rich interfaces, complex designs, pages that load slowly.Google simply dominates that traffic that I receive form the website. This does not mean that people do not use Yahoo, Bing or other Search engines

From an SEO standpoint, there are a few things different from bing/yahoo’s indexation when compared to google. With google, you can get content indexed instantly whereas bing/yahoo takes about 2 weeks at the quickest. Bing/yahoo also places a lot of weight on microdata. I ran tests on this recently, and found that microdata makes a HUGE difference in organic search ranks in bing and yahoo whereas google showed no effect. Another thing bing places a lot of emphasis on is rss feeds. If you submit your feed as a sitemap, you will see better results. Bing also gives you a slight boost just for setting up bing webmaster tools, whereas google places no weight on having GWT set up.
