Yeah , as you can see i have 3 signatures in my posts , My question is "Does it have same positive effect as it would be if i have only 1 signature "or does it affect any way ?Thanks
Well, Yes but not really enough to notice. One of the MANY factors on the weight/power of a backlink is how many OBL (out bound links, or links on a page) there are. Obviously the more links the less weight. But again this is just one of many many factors and on a forum where there could be 10-20 replies with other sigs on the page or just you its not really controllable, or that big of a deal.
Now, i can't edit my signature, but i think we can full use of the signature, we can use dofferent signature point to different webpage.
