Do any of you here, who have successful sites directly blast your established money sites with thousands and thousands of of forum profiles and blog comments? I'm not talking about little sites with a couple hundred daily visitors, making a few bucks a day. I'm talking about actual successful established sites, ie been around for 5+ years, natural backlinks, thousands of visitors a day, thousands of dollars a month. Right now I'm indirectly blasting links, and wondering if I should start doing direct links? My one site is 11 years old, gets about 3,000 visitors a day, with several hundred natural links. But it's not really ranked high on search engines, it just has a ton of unique, quality content. B ut this is my main income and I don't want to damage it at all, or even if there is a chance to damage it.
