It is well known that it is not sufficient for a good ranking to just have an optimized website for the keywords. More important are links from other sites to your site. There are different types of links and it is always clever to understand a little bit about it.
You can exchange links with another site. For that reason you get in touch with the webmaster and offer him a link. If he agrees you obtain a backlink from his website to your website. Those links are reciprocal links or Two Way Links. You should make sure that you get links from related sites, it will be better loved by Google. The best links are links from your competitors because they are most related. But you would rather sell your own product and do not want to recommend the product of your competitors. more..getting many backlinks
Two Way Links don’t increase your ranking significantly in Google, of course they are better than no links. Google loves One Way Links. This is a link from another website to your site and there is no link from your website to the other website. Web directories give you such links. But they contribute less and less to a good ranking. One Way Links would be of course again the best of a competing site because they are very related. But nobody wants to link to your website and get nothing in return.
But if you have two partners B and C, you can proceed differently. You (A) link to B and B doesn’t link back to you (that would be reciprocal) he links to C. C then links to A. Everybody gets an incoming link, but for which there is no direct outgoing link. All are linked in a triangle: A -> B -> C -> A. Google sees only incoming One-Way Links, that’s the best for the ranking. more..increase your pagerank with LinkNetworks
