For the past 2 months Iv been doing all types of seo using mostly the services found here with much success. My question is: I have many different websites and im using many different service providors for my link building campaigns. Im trying to be very careful not to use the same service on the same url more then one time, feeling this may raise a red flag. Am I correct in that assumption, or am I missing something? With the many sites Im working with, the record keeping is overwelming, plus I see a time I will run out of unique service providers.
