Blogging is not what it used to be. In fact, many digital marketing experts will argue that blogging is not an effective use of your marketing efforts the way it was even 2 years ago. With so many blogs--and the vast number of blog entries across the internet--the overwhelming majority of blog posts simply don't get much traffic, if any at all.
If you have pages on your website that don’t get any traffic or get bad traffic, they will work against your digital marketing efforts and potentially harm your search rankings.
The game, today, is about writing amazing content that is meant to last. You're better off writing one incredible article and updating it regularly as you analyze your performance data rather than writing several mediocre blogs that no one reads.
