bookmark your Links as favorites - free backlinks

Bookmarks, backlinks and favourites are the three mosts important keywords of a website.
I believe that a webmaster wants to present his website in the net in such a way that it is noticed, found and viewed. How could this be achieved?
Of course by search engines! There are quiet a number of search engines as google, bing, yahoo, alta vista et. al.
They want to be fed with search keys to supply you with ideal results to your specifications. So how can you affect this? For search engines it is only possible to relate to the entered keyword(s). These correlations will be evaluated by their frequency on your website, by surrounded text and how often other websites with these definitions will show your website or are linked to it.
On your own website you can influence directly the text or frequency of the keywords. It is far more difficult to exert influence on other websites and their links to your own website. These links are called backlinks. Backlinks are created by registering your website in web-directories or linklists i.e. or link exchanges with other webmasters. If a visitor of one of these lists will click on your name she or he will directly be passed on to your website. These encoded relations will be identified by search engines and regarded as links or backlinks.
