definitely one way and moreover three way links are similar to one way links although the concept is different, but ine way links are always the best
one way links are the only type of links you should even think about building. I have been building "link lines" for a few weeks now and the strategy is working well.
"link lines" ? is it like "triangle link" A -> B -> C -> D -> E -> A ? i need some good idea about one way link ( A -> B, B -> C, C -> D, D -> E )
One way links or more than two way links are better. For specific two way link exchange patterns, make sure that two site should be quite similar in niche.
1 way links are very beneficial to improve the website page rank also its help to boost the ranking of the website.
One way is the best kind of link of course. Reciprocal links can be had by making a deal like at DP link exchange and so it does not have the same value as a one way backlink. Do enough of three way link and you got yourself a linkfarm. One way link all the way.
i think google already smart to detect this, especially if the site using same IP / hosting ... i dont know for blogspot / wordpress.com
