I have a website HTML-only, which I made in 2012 for my uncle’s business free of charge.
However, in 2015 he closed the business and no longer needs the website. So, since I spent so much time on the theme and it looks already good enough to be sold, I have decided to sell it in themeforest.
Howerver, this will be my first theme, and I would like to know what to do to make it appeal larger clients.
Time is no issue, I only want to sell it when I feel like it is perfect.
So, my question is, aside from the design choice, what do profitable themes have in common these days? What can I do, or make it with so it can be among the best selling themes out there?
