How you'll sell this?

Hello, i know now i'm going to ask a question that so many people don't interested to answer. Specially share their methods they know or they are succussed at. But still, i want to know.

My Questions are:

1. If i gives you an Product link (Affiliate link of any Network) how you will sell this? (excluding paid methods)
2. How much time you need to sell the product?
3. What strategy you plan first to sell this?
4. If you fail what you do then?

1.see if the product have audiance for it, research the audiance, how to reach them, what kind of way i can use to reach them.
2.unknown, no one know for sure till you dip. with the same niche someone can suceed in hour, other in months, some even years before turning profit. your experience and circumstance decide this.
3.basily same as 1 answer, finding audiance and how to reach them ,every audiance is different, some active on forum, other on discord, lisit goes on.
4. recheck what i do wrong, what i need, also my competitor to compare. fix it , make it better, redo it, and review.

it's not people don't want to answer, it's jsut the answer is so generic, there is no magic mantra or surefire method out there.
it;'s like asking how to suceed on trading at crypto or forex? do you want more magical answer than "buy cheap and sell high"? yeah there is none other than that
what make it different is the decision based on layer of experience and skill, build with effort,failure and time. put it out there for people to copy paste? yeah you cannot.
how you share a method of making decision that is different for each people, since everyone have diff circumstance??? (skill, experience,intrest,emotion, capital etc)
