Your Pro Research Member Status at $360.00/yr Is Too Expensive.
If you charged $10.00/month ($120.00 yr) you would get most of the people who visit Seeking Alpha to sign on and probably make more money. In addition, that low fee would attract even more people who would have been very unlikely to pay for a more expensive subscription. Be careful here because you have plenty of readers who will stop coming to Seeking Alpha if they have to pay $360/yr to read most articles of any value
Pro Research is listed for $30.00/month and Pro Plus is listed for $200.00/month and those are the only two Seeking Alpha selections that I see
