Make your business blogs interesting to your target market by documenting what you do each day in your business, how you help clients, whats made you more productive. Be real, add interest by telling stories and adding images.
For best results include a clear bright photo and make your headlines catchy.
I would always recommend posting to your blog and then sharing snippets to Social Media with a link back to your blog. The aim of marketing is to motivate people to learn more about your products and buy. Always provide a way for them to either learn or buy from you.
