Do you promote daily? Every few days? Once or twice a week? I think there is a limit to how much you promote, because you also don't want to spam promotions on social media over and over. It's fine to pay for paid advertising on social media, but if you're posting promo to your own socials on the daily, people will just see that as spam and peace out. Instead only promote on your socials on special occasions. Maybe once a week or twice at most. The point is to grow your social media audience, so that you gain more traffic when you do promote. But, overdoing it on promotion will result in your socials looking spammy. So post other content, interact with users, have fun.
