Personally I'm using it for about 3 or 4 months already. Didn't see any improvements yet... except, pagerank of my sites, maybe, they are pr2-pr3, but still not sure that's because of them or not. Just need your opinion, I'm wasting my time with these kind of links or not? Do they still effective? Thx.
i started to try before panda and before panda worked well but arfer panda algo seems not so much effective...can any other free backlink web site suggestion?
