In google eyes backlinks are votes people gave to a certain site. It will earn the site an authority on it's niche. More backlinks mean more autorithy if they are in related topics, autorithy in SERP means relevancy with the search term.
Hi drayserawon thanks for your post, Plz read read again and post your information, or if any other? Plz..............
thnx for u r great information.. friend....backlinks are the very important thing... thanx once again....
more backlinks you have, higher you rank in general. there are other things to consider as well like quality of those backlinks and links form good neighborhood. but not going that deep, in general, more backlinks you have the higher you rank for your keyword
Backlinks are like popularity votes. Google sees other sites high Pagerank sites linking to you and thinks, "If all these other sites I gave a high pagerank to are linking to this site than it must be good".
Do you mean backlinks from any Google service? If so, having inbound links from Google services such as YouTube and those can really rank you better in Google but not too much on Yahoo! rankings. But having more inbound links can really help.
Google always gives higher importance to sites with higher number of backlinks. So they help site improve in Page Rank and in the terms of keyword positions, SERP.
