Manual link building is the safest methods, quality backlinks are better than 1000's of low quality back links
comment demon its the best software for comment link building but its not free if you using wordpress send me pm i give you free auto link building plugin
It seems that you should try manual blog commenting and to remain social in your touch as using software is not going to work any more. Google now makes sure to give preference to quality links rather than quantity.
I'll not recommend you to use any software to do blog comments. It comes under black hat SEO if you use. Do manual comment on your niche blogs so that you can get dofollow links from there. Good Luck!!!
