You mean affiliate program?

There have been plenty of directory services lately. During that same period, I also launched indieproducts.io. Luckily, it has grown organically, and I get at least two to three submissions every day (I approve one product a day).

Other than simply charging for submissions, what other ways could I monetize this service?

e.g. - Top spots(top 1 to 3 rows) for x number of weeks or months? - Write blogs and YouTube reviews for the paid submission? - What else could I offer as a paid service?

Many already pointed out that your writing is good. I will just add, read about "imposter syndrome". That will clear some of your doubts and you might start thinking in a different direction (at-least for writing capabilities if not anything else).

p.s. I totally understand your feeling. I am also a non native English speaker.

BTW, accessing metarank.ai gives warning. May be because it has Meta in its domain name but Metamask shows this message --

This domain is currently on the MetaMask domain warning list. This means that based on information available to us, MetaMask believes this domain could currently compromise your security and, as an added safety feature, MetaMask has restricted access to the site. To override this, please read the rest of this warning for instructions on how to continue at your own risk.

Exactly, that is what I was hoping to find in this article. But if they disclose it might open up new opportunities and so quite possible we would never know.
