Used tools for backlinks checkler like opensiteexplore, ahrefs, majestic etc which are really helpful for link building.

 

Build link naturally by developing high quality content.

 

I use multiple ways for link building to my websites (www.zestapps.com). The most useful strategy that I could follow is guest blogging, which often drive a lot of traffic to my site.
Another way , I try to answer questions on a daily basis on Quora. Where I can post my link, although no follow but Google counts Quora which is somewhat beneficial for me, also I can build a reputation by getting badges.
