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.
Its not just good content that matters, presentation of post is very important too. Have attractive pictures, fonts etc to hook the readers.
Write something useful for your readers. Share a relevant piece of information, an event update or a hack that makes a task simpler
