Hi All, I have a question for those of you who build links aggresively, How long do you find these sites last once they rank? I have an ecommerce site and im looking to open up more of them in different niches but post penguin im having to rethink things a bit. In my current niche the sites that are up there for the big keywords don't have much done to them in the way of backlinks they never dominated it like I did though for many different keywords prior to penguin. Im thinking from now on it may be better for me to go blackhat and have other sites on the boil as backup for when the main site inevitably fails. Does anyone else do this? I wouldn't mind losing my rankings say once a year and promoting a new site to the front line but if it's only going to last 4 months it may not be worth it for me. Thanks!
