Yes as a faucet owner faucet are still profitable but profits are low compare to 2017 but as a faucet worker faucets are nowadays not profitable that are time consuming and their payout is very low so I would suggest everyone who wants to earn through faucets never waste your time in that you can use those time in bounties this is just my suggestion.
What's your faucet? I'm quite curious.
What i've gleaned from this is that it can only really be profitable (and not that much) if you have a faucet website.
Whether or not faucets are profitable from a user perspective really boils down to how much your time is worth.
It may be profitable in Venezuela......since they only make a few usd per month because of hyperinflation. For everyone else though, no its not worth it in the slightest.
Agree, this was viable business in years before. Still such new faucet can contribute to community in some cases like in very poor countries or people that want to just "test" bitcoin and see how it works.
Maybe you will be able to get great advertisements (for great $ to you). It only depend on your selling skills
I doubt that this "depends" on your selling skills, but rather how much convertable traffic you're getting and what your site looks and functions like. Just saying.
How to own them, are there any sources to learn about faucets like how popular you are?
Well, google should be your first step;
https://www.google.com/search?q=how+to+create+a+faucetThere's dozens and dozens of guides and free templates out there that you'll be able to use. A complete newbie to programming could make one.
As to the metrics, most adnetworks either ask you for your google analytics, or
your alexa ranking.
I'm a little bit out of date on the current meta, but i'm pretty sure faucethub.io is still pretty popular, you can see their most "popular" faucets here ->
