Instagram can be a great tool for gaining more potential customers.
All you need to do is create a business account there, which can also be linked to Facebook. In the settings you can also switch a personal account to a business one.
Instagram is built on images, so the core of your promotion here is photos, which above all should look good, match your business profile and appeal to your customers. Another important element is posting regularly on Instagram: even if your photos are exceptionally good, publishing them once every two weeks will not do much to bring traffic to your profile.
Consistency and patience are the foundation of running such an account. It is also a good platform for exchanging short thoughts with customers: you can ask interesting questions that get your followers engaged. And every follower can be a potential buyer of your products. If you want to put a link to your website in your bio, remember to shorten it, as short links look better and get more clicks than long strings of text. A business account on Instagram should ideally have a consistent visual style: perhaps the same filter, the same framing or a recurring graphic element that becomes part of your brand's visual identity and appears in every photo.
Your Instagram profile should also be stylistically consistent.
