roboform is recomended and no other else, there is not any good "link building software", if you use them, sooner or later you will got caught by google.
Hi, Social Bot worked great for me. But due to time management I mostly outsource my task and rarely use them so I have decide to sell them for some cash out. I have 5 Incansoft bot software for sell. All are genuine product. If anyone interested to try them please PM me. You know original price is $30 x 5 = $150 You will get from me only for $19 Thanks!
I have been using IBP for many years to manage my link exchanges and it has worked great. I don't know if you were just asking about 1 way link building tools, but if not you should take a look. It is kind of pricey though.
