Consistency is important! You need to decide how often you are going publish a blogpost. Also do it on the same days. For eg if you decide to blog every Monday, keep posting every Monday. If people love your posts they will subscribe and they will expect to see new blogposts every Monday. There is no restriction as to the number of blogs you an post, just be consistent. There are people who blog bi weekly, once a week, every second day or daily. Should you wish to have more than one post a week you may choose to have guest bloggers to relieve the pressure. You may choose to theme your posts for eg Mondays would be motivational Mondays where you post motivational and inspirational posts. Wednesdays could be Wacky Wednesday where you loosen up a bit and have some fun, all within reason and always remembering that you are representing a brand whether that brand be you or your business. Blogging is a brilliant way of directing traffic to your website regularly. S every time you publish a new blogpost use your social media accounts like Fb, Twitter, LinkedIn to get the audience to go and read the post on your website. This will also help with your site's Google ranking.
So! When you are ready get into it and embrace blogging. You don't have to be a writer or journalist to do this, you just have to be passionate about your topics!
