Yes, there can be a downside to blogging. While it is an effective way to reach out to potential customers and build relationships with them, it also requires significant time and effort.  Additionally, if the content isn't well-written or relevant, readers may not engage with it and could even become turned off from your brand. Furthermore, without proper SEO optimization techniques in place, blogs can get lost in the sea of online content.  Lastly, depending on how you monetize your blog's success (e.g., ads with google adsense), you may end up sacrificing user experience for profit which could lead to fewer returning visitors over time.
