Amazon Affiliate Program in 2019 - Worth or Not?

Good thinking, I don't want a big budget at first try, guess I would try with your method

Present I have Amazon Affiliate site, I have started this in the month of Nov'18, I invested around $1200 for this project, earnings till date $6.
My advice is for amazon affiliate sites, there is huge competition out there, iam trying to rank low search volume keywords say below 500 now am @9 in Google SERP.

Absolutely realistic within that timeframe and worth it. It's one of the most old if not oldest and stable player in the market which converts well and pay on time evertime. You need to have good content rich site for like 15 pages or they may not accept you and be sure to make a sale within that timeframe LOL

Amazon Associates, the Amazon affiliate program, is a great program to work with, especially if you’re a beginner to affiliate marketing.

There are many people, who over the years have made a lot of money with Amazon’s affiliate program. And 2019 is going to be no different.

The only difference between last year, and this year, is the number - 2019. Nothing has changed to make affiliating with Amazon not work - meaning that it will still work for this year.

Amazon gives commissions out based on the category of the things you’re promoting. So health products are (I believe) a 5% commission, where as Amazon rare coins are worth 10% commission.

Because of this, it’s important to look at the categories and see which ones you can promote, to get a better commission.
