First of all you need to get a Google Adsense account. I'm not sure if you can do anything here insofar as earning money without a Google Adsense account.
Now, that all said, Google may not just up and give an Adsense account to folks these days. I'm not sure. I've had one for at least 7 years now, and I see other people saying the process has changed. It may be you need to publish a few pages of sufficient quality for Google to give you an Adsense account.
You'll have to get one - regardless, if you want to make money by publishing writing here, and the same will be true just about anywhere else too.
Secondly, you'd need an amazon.com associate account so you can include products for sale on your writing from amazon.com
This making money with writing thing is not easy. At least it dang sure isn't easy for me. And it has gotten harder, I think, over the years to make money online. Maybe there are more people trying to do it now, I'm not sure.
I don't mean to be discouraging. You may damn well be the most fabulous writer with the most insane skills at making money online there will ever be - so get that Google Adsense account, and then knock 'em dead, you know.
