Hi guys, I've been a reader of the forum for a while and really enjoy it. This is my first question, so apologies if it's been asked before. I did do a search to see if it had but I'm not sure if the answer to my question has been compacted into one post. Basically, I'm a white hat seo but have a few greyish ideas I want to try out. My main concern while I experiment with these is making sure the blackhat sites and the whitehat ones never get linked. I've seen a few people mention about covering your tracks, but was wondering a) what I need to be concerned about and b) what tools/processes are best for doing this so I can sleep peacefully at night? Any suggestions?
