In search engine optimization , backlinks refer to hyper-links pointing to a particular Web page. Backlinks are important to SEO, because Google considers the quality and quantity of backlinks to determine PageRank. A backlink is a link coming from another website to your own. The number and quality of backlinks that your site has can affect your search engine optimization efforts, as some search engines provide significant weight to the backlinks of a site.
Until recently, they couldn't, except by using backlinks as a proxy (more backlinks suggests the content is 'good'). However, they can now analyse a page in situ and detect whether it is well written, or badly written. For example, your initial question Can any one Explain me about in detail? is VERY bad English, and wouldn't pass Google nowadays. It contains no less than 4 errors *, being charitable, and is exactly the kind of thing the Panda will now pick up instantly as 'badly written / badly spun'. * 'any one' is actually one word, 'anyone'. 'Explain' is wrongly capitalized. 'me' needs a 'to' in front of it, or shouldn't be present at all. 'about' needs a subject.
Backlinks are crucial but content/service is what counts at the end of the day. No matter how high your PageRank is, if you have no returning visitors then your SEO campaign is almost useless.
You want original content, with minimal grammatical and spelling mistakes; not reused or poorly spun content. Edit: I didn't see your reply contentboss..
