I'm new to selling solo ads and make money this way. I assume that if you've got a list of over 5000 subscribers, then you could make a quite good profit selling solo ads right? I will be creating leads in the personal development niche. Today I went to Udimi website and had a look. I didn't notice anywhere that all the sellers mention what niche are they in. Is it important that you sell to people who are promoting in the same niche? Where in Udimi that the sellers mention what niche their list is in?
