Here is where everything starts. Starting a blog will allow you to be able to create credibility and presence for your brand. Creating posts should always be directed to offer your followers value from an expert in the area like you!
Try to be consistent and post blogs regularly to stay positioned in your client's minds. When I say regularly, I mean maybe once a week, once a month or as often as you can, planning your topics in advance and always offering valuable content.
You could also blog about reviews, recommendations, or just your personal life... Remember, once you start getting people's attention, try to post at the same rhythm! Good Luck and enjoy your writing! :)
