I know this number depends on alot of things, but with what was once a weight of 40,000 (now 3500 since the weight change), I have never used more than 2. I hear people saying to have more to avoid throwing up any flags, but how many is a good number? I just increased my number to 6, by the way.
umm, I dont think it matters how much you put. It counts as a percent. So if you only have 2 links and both are at 2 it means they are both 50/50 of your 3500 wieght.
I understand all of that. The concern around here with some though is that if you have too many links popping up for a keyword, it could trigger a flag with places like google, which is why people say you need more links in the coop.
