The first publicity channel we like to mention is a no-brainer: be present and active on social media. Let the world know that the products that you are selling are worth buying! We're kicking in an open door when we say that an app like
Instagram is very useful if you sell products that are very
visual. Think about clothes, apparel, cosmetics, ...
Are you selling products that require more
explanation and story-telling? Instagram is then less a choice but
Facebook could be your primary social media channel. You should also take into account that when your target audience is younger, Facebook will do less the trick. If your buyers are primarily under 30 years old, betting solely on Facebook will generally not work well.
Apart from Facebook and Instagram, don't forget
Pinterest (certainly when you are in lifestyle products), or even
TikTok could be a potential medium for your business. TikTok was in its starting days primarily used by teenagers and kids, but this has changed the past year.
An extra tip for those posting on Facebook: try to
make the content of your Facebook posts valuable, in that sense that you should avoid to always repetitive post a "buy now X", or "buy now Y". One time you post some content, next time you post a commercial post, this way you get a balanced Facebook feed and you don't scare away your followers.
