It is well known that it is not enough for a good ranking to only have an optimized website for the keywords. More important are links from other websites to your website. It is of course not bad to know something about the different kinds of Links.
You can exchange links with another website. Therefore you contact the webmaster and offer him a link. If he agrees you get a backlink from his website to your website. Those links are reciprocal links or Two Way Links. Bear in mind to ask for a link from related sites, they are more important to Google. The best links are links from your competitors since 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 boost your ranking significantly in Google, certainly 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. You can get such links from web directories. But they are not very significant for search engines. Since they are very related, One Way Links from your competitors would be again the best. You sure have problems to find somebody who gives you a link for nothing in return.
You can proceed rather special if you have two partners, B and C. You (A) link to B and B links to C and not back to A. C gets a link from B and in return links to A. Everyone 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..getting many backlinks
