Want to be a content writer, need some tips from experienced content writers

I want to be a good content writer. Until now, I've only made $80 or something. My chances of success are really low. If there's a potential client and he asks for some samples, there's a 50% chance that he'll reject me because he doesn't need the kind of content I write.

So that's why I need some tips.

• How exactly do you write?
• What are some general tips?
• Some mistakes to avoid?
• What sells?
• What sort of writing are clients these days looking for?

I am coming for a buyers point of view, which might be useful as well!

I love flexible writers, writers that can be given any given topic - do thorough research about the certain topic and deliver a well-researched article. Something I really enjoy as well is when writers as necessary questions that I might miss to call out. I might just say "Write about this topic and include these keywords" and some might just start working on it. I prefer when the writer ask me like "Should I write about this as personal experience or from a third-person angle?" and stuff that will make their result product more what I need it.

Any given topic is needed. I guess as the fitness niche is huge there is a demand for content there right now but overall, anything will do really. Sign up for Upwork and other various freelancer services and test your luck!
