1- Good content- having good informational content is good for your audience. If you think you can’t make it yourself you can always outsource the article and have someone create it for you. Try doing tips, collections etc..
2- Create videos- content is good, and content on a video is much more powerful. Is really inexpensive these days to record a professional one. You can use your iPhone or android or buy a cheap camera on amazon with hd definition.
3- Advertise on networks: If you have a budget and you’re able to choose where to promote your business, I will suggest you go outdoor. You can try valet podiums where digitally you can advertise, benches, busses etc.
4-Use Social media: Everybody uses cellphones these days, and specially one person may have more than 1 social media account.
