I would also like to increase my traffic. But SEO is not something I am great at. I getting about 500 hits a day http://testomoz.org/hits right now.
I noticed also I get a spike in visitors when I release a new addons in addons.mozilla.org so I think most of my traffic comes from there.
Should I move my site around so I have http://testomoz.org/projects/ as my home page?
In ScHwErV's thread is was said a web ring is bad. But if I got together other extension developers, would it really be bad. Since I would not be directly be competing with them since we offer extensions that do different things?
