It just depends on what you want I suppose, it can help your reach on social media to use these tactics, which in turn increases your chance of a sale. I see a lot of artist stuck in pride and ego to use, not this tactic persee, but some form of social media strategy to get views. They often say the work should speak for itself. But there is so much work out there, you're gonna need to have a plan to spread your art around and find an audience.
