Though I am not writing copy for advertising, I have learnt a lot about writing by offering myself as a copywriter on Fiverr. I was paid to find out that I didn’t like writing texts for web pages, that I am average at writing short blog posts, but that I really like writing long blog posts about more technical subjects (even subjects I didn’t have a clue about before I started writing). Doing different writing assignments for different people and different audiences is a good way to learn it.
2. I also read a lot about SEO, CRO, and marketing in general, so I do my best to be a triple, or even a quadruple threat. Very recently I’ve done a 30-minute CRO consult with a client that *tripled* her checkout conversion (like, actually increased sales 3x), taking her from 5 figures per month to six figures per month in revenue. It definitely pays off to know how to do things that are related to copywriting. :)
