We recommend focusing on creating content that either educates or entertains your audience on topics that you specialise in. Answer their questions and they'll seek your expertise.
Your content needs to be authentic, visually captivating and optimised for each platform. What works well on LinkedIn will not work well on TikTok for example.
Maintaining a consistent posting schedule and branding will also help you grow your followers.
Lastly, consider leveraging influencers in your niche through sponsored posts or giveaways. The reason this is so powerful is that your target customer base already follows these influencers and this will help them discover your business.
