BackLinks

Links of course play very important key role in seo and getting your website in top ten. No all lings matter though. Even if you get links form websites with high PR (PageRank) it doesn't mean that you will benefit greatly from them. What matters is to have links related to your website. Thus if you have webpages with content about traveling get links from similar websites.

Sometimes you can be even punish if getting many links form "bed neighborhood" as Google calls it. Thus find the-same-category links or good and solid directories instead of many worthless links from websites not related to yours or small directories created only for a purpose of linking.
