Keep your posts simple! Do not try to impress anyone. be yourself! Visit other blogs which might interest you, take part in conversations or simply put your two cents for others to read and follow you back to your blog.
Create infographics for your blog to summarise the content and present it in a more interesting way.
Make good use of media (audio/ video/ embedded tweets, etc.) in your articles. It helps in grabbing the attention of the reader and supports your text.
