Last year...xrumer, scrapebox and social bookmarking did alot to your domain serp rankings. Now I see that it does more harm than good. All these blasts of 10,000 links will send your domain packing to stay a few pages back from where it organically found itself. I think I wasted alot of money on these kinds of things. I'm thinking a few high pr links here and there, article submissions and updating your sites content frequently would do the trick. Do you guys have any other suggestions?
