What is seo(Search engine optimization)? Give an detail note about that plz!?

It is making your website in a form that the search engines can navigate easily. Say you had an internal link that was broken, that would be lack of optimization. If your coding was not right the search engine robots may not be able to follow it and give up. This is one of the problems ociated with writing in MS Word or maybe even Dreamweaver.
