I bought a solo ad from Thomas Burke for 125 click for $37.50 or $0.30 a click.
Thomas promoted my Top Plugins for WordPress site
Here’s my receipt:
Here are my results:
I got 190 visitors from Thomas (65 extra) and 79 optins for a conversion rate of 42% and a cost per subscriber acquisition of $0.47
I recommend buying a solo ad from Thomas because everyone can afford it and the results I had were very good.
