Tip #1 - If you read any information on the content you are writing, you must cite your source or you'll risk having the article declined. Even after all my time on AC, I received a decline notice the other day because I inadvertently included my sources in the "Resources" section instead of at the end of my article like the guidelines stipulate. Write that one up at a big Homer Simpson, "Doh!" for me. I knew better. I must've been super tired. In other words, at the end of your articles, write like so:
Sources: (then proceed to link up your sources here)
Tip #2 - It is unlikely you'll make enough money to live off of just by writing for AC. Look around to write for other sites. Having said this, you can make the most out of your content by offering them to AC as non-exclusive. I've made this mistake so trust me. There's not much difference in the amount of upfront payment that AC will offer you compared to the money you can make by offering the same article (maybe tweeked a little) to another site. Don't limit your options! Offer as non-exclusive!
Thank you. That's all I have for today.
