Which is the best way to promote products or refferal links? Social media and forums is total shit,no one interested in this.
You need targeted audience. When most people go on social media they are looking for social interaction, they are not looking to invest in some strange digital currency they do not even understand. and they are not there to take lessons and be educated on it. They want to see train-wreak cousin sally make drunken posts or look for cooking recipes.
People market on social media because it is easy and it is usually a fruitless time suck.
IMO the best way to promote products or links is to provide valuable information to viewers-Quality web pages, blog post, podcasts. When you provide quality information you are also showing your self as an expert in the field=gaining trust and you are dealing with a targeted audience that is already looking to research and buy.
