So I'm building backlinks to a brand new website (3 weeks old now ish) in a white hat only way. How long do you guys give links to work? I've seen some people say a week and I've seen some people say up to 6 weeks? Or is it when they're reported in Google webmaster tools? Any input would be great damn it fu*ked up the title lol, hopefully people can work out what I'm saying!
