If I started a forum backlink service would anyone be interested? Your website would receive at least 5-7 permanent one-way PR1-6 backlinks per day. Price would be reasonable, about $10 a day. Would only be able to do this for no more than 2 people at a time, however. Let me know if this interests you. Edit: Not only will this boost your PR and help your targeted keyword rankings, but it will also give you more traffic.
Yes, but only on highly targeted posts with PR. Not only will this boost your PR, but it will also give you more traffic.
