I'm currently building a list in MMO, IM, and health niche I have a small list now but what are some tips to become a solo ad provider and provide the best service?
Keep building and start by doing 50 click solos and work up from there. Build up multiple autoresponder sending service accounts so you don't have to rely on only one.
Reinvest all your profits until you can consistently generate 500 clicks per day minimum. Stay consistent and trust Udimi...buy ads. You will need to go a few months before you can take profits out.
Best of luck
Stick with it! Lean into it and you will keep learning more and more as you go. Great job diving into this... Not a lot of people do. But the ones that do... they Do pretty amazing.
