Incoming links can help your ranking
One of the search engine marketing practices that I am constantly involved in is building links to websites that I market. This means that I contact other webmasters with websites that may have a similar theme to see if they may want to link to my sites.
How I find the sites that will link to me.
Why link building?
Link building is like going out to get votes for your website. Links that point toward your site say to a search engine that your site is worth looking at. Try to think of each link that aims at your site as a “vote.” Let’s say you are trying to win for the search “link building.” All things being equal, the site with the most links pointing to it that say “link building” will win the search. Same thing is true for every site on the net. If you are trying to win for a search, you will do that by having sites point toward your site for those keywords.
