How can an artist attract clients without advertising? Let's start by understanding what advertising is. If an artist runs their blog, which automatically increases the site's ranking in search engine ratings and boosts traffic to the site, is that advertising?
And what if the artist writes a very useful post, providing valuable recommendations? And then they want as many people as possible to benefit from these recommendations? Because they're genuinely helpful. How should we perceive a request to share the post in a group with 100,000 followers?
Yes, undoubtedly, when an artist shouts about being the best among all artists, it doesn't look great, agreed. And if they further promote themselves in ads with a cry of "come to me, I'll draw everyone better than anyone!" I sense your smiles. But. If an artist knows how to, for example, decorate a living room or office, or how to draw an apple, or choose brushes, and they write a series of posts about it in their group or profile, why not share this useful series with people? They're not directly advertising themselves. They're not promoting their services overtly and with a shout. They're doing it much more delicately and effectively. They simply provide value in their posts and want as many people as possible to read them to genuinely help as many people as possible.
Thanks to these actions, on one hand, information about the artist spreads, and on the other hand, clients find them and place orders. Everyone reads tons of articles and posts on Facebook. Suddenly, they come across an article by an Artist. The reader likes it and subscribes to a series of similar posts. It's all ethical and beautiful, isn't it? Then the reader feels a connection with the Artist, resonates with something (or doesn't, everyone has their preferences), and reaches out to the artist to buy paintings. Here, too, everything is ethical.
