Is it true that forum signature links are good for back links?
Also how to decide the number of signature links needed for one keyword to desired result ?
And How to split it up? for example 500 signature links from one or same forum are as good as 50 signature links at 5 different forums or would 50 signature links from 5 different forums would be better?
