Some of you already using this and but I thought to post it for those who haven't heard about it yet. This offer is from 247backlinks.com and they offer you 50 Free backlinks per day which means 1500 backlinks per month !
Okey now these are not high quality black links. Probably some kind of blast software and these are blog comments. Those you get from ScrapBox. success rate is probably not 100%. But still it's FREE and it can be useful.
I use these to get backlinks for my first layer and second layer blogs and web 2.0 properties of my money sites. It's fully automated and you can add up to 25 sites and they send 50 per day to one site from your list. Like 50 links for siteA today, then tomorrow 50 links for siteB etc etc.
Also you get 10 more backlinks for each person you refer to their system. Which means if you refer 5 people it means 100 backlinks per day (5x10 + 50 =100). Here's the direct link to the site but It would be great if you join under me from my signature link. Win Win for you and my self
