You can increase your website traffic on this site by following the rules. No spamming of your links in the posts are allowed. Otherwise this forum would be just a bunch of links to spam sites.
If you would like a backlink from this site you may promote your own site (no affiliate links) from your profile signature. This shows up at the bottom of every thread you create and reply you give. However, junk threads and replies will be deleted. In addition to the backlink you will receive traffic from your signature link.
Once you've tried doing that I'd recommend
getting backlinks with social bookmarking, commenting on related niche blogs,
create free press releases and submitting to the
best article websites to build up your incoming links.
