Ideally- every day. The more frequently you update your blog, the higher it ranks. However, if you cannot do that, write at least one blog post every week. It is better to write at least 3 blogs every week. The best way to ensure that is to make a routine for yourself and stick to it. Remember, blogging is a matter of practice, and it takes time to make it a habit. Writing your first blog post is the most difficult step. But once you complete it, don’t stop. Keep writing. Train your mind and body to write regularly
