A blog is like an online diary.
Having a blog on your website is a great way to market your business. Blogging about subjects related to your business can demonstrate your knowledge and expertise in your business field and personality.
Moreover, potential customers may visit your website to read your latest follow blog posts and if you allow commenting, they can engage with you by leaving comments that you can moderate.
Search engines, like Google, also will rank your website higher if you blog regularly, which increases more potential customers visiting your website.
So consider having a blog page for your website, but only if you can commit to blogging regularly.
