Earning by comments will require you to have your own Blogs and Websites. You will then share these dedicated domains (Owned by You) in the comment window. If an option to add your URL or website is not available, then you do not include links. You contact the site support first and get permission to share your URL. Oh, and NEVER share affiliate links in comments.

I make the bulk of my money from blogging. In addition to the advertising revenue streams mentioned above, I also receive flat rate payments for blogging from various blogs throughout the web. I’m paid to write as a whistleblower, financial analyst, reviewer, commentator, and more. Writing for other sites builds traffic to my personal blog. The traffic for this blog gives me clout to present to advertisers.
If you're interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service and refunds. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. It is hard work, especially on your own. You could opt for Amazon's platform, which might be an easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not.
If you're looking for a quick fix, sell gigs on Fiverr. Everyone knows about the gig economy. It's evolved over the years. And today, they're not just five-dollar gigs that you're selling. But, you need to build credibility first. Deliver real value. Go out of your way. Get stellar reviews. Then. And only then. Can you really kick things into high gear.
