I'm always suspicious of these guys if they have a low
PR - these ones only have a
PR 2
About outsourcing linkbuilding:
I tried quite a few of them and all were an absolute waste of time, below my experiences:
- One submitted to automatic link building services creating over 2000 backlinks in one week. My site was banned from Google, traffic dropped to almost nothing and pagerank went to 0
- One promised me 150 high quality links - he just wrote 2 simple articles and submitted it to article directories, which delivered very limited response
I could go on and on.
In summary, I have spent thousands on outsourcing link building and in the end I recruited a couple of people myself to do it in house, with much better results.
Whatever you do, do not pay before you see the result, because it is almost always not what you agreed on.
Hope it helps -
