If you are serious about earning money online through article writing, then you should try iWriter or Fiverr. Both sites do not pay much, however they are easy platforms to get started with. On iWriter, you sign up for free and you must create a piece of content as a screening. Once done, you will be able to take on work as it appears on the job board.
Posting ads on Craigslist is technically easy, but people often have fears about posting their personal information on the site. I communicate mostly through email when doing business on Craigslist, and I’ve never run into any issues. I’ve never been ripped off, nor have I been murdered or raped for using the site. It takes common sense, so use your best judgment, but don’t assume someone is a thief just because of their preferred communication method. For an extra bonus, google “funny Craigslist ads” to see some delightful examples of guerilla and grassroots marketing.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
