Should You Use AI-Generated Content?

In the latest Google Search Update from March 2024, Google announced updates to reduce spam and low-quality content in search results. The new implementations include algorithmic enhancements to reduce unoriginal and low-quality content that hinders the user experience.

Although not directly, this update encompasses AI-generated content by emphasising the need for originality and reducing the visibility of content that lacks depth or is mass-produced by AI. 

So, does this mean that Google will punish any AI-generated content with low rankings? Not necessarily. The update emphasises the importance of ensuring that AI-generated content meets certain quality, originality, and depth standards. In other words, Google wants all content to be helpful and valuable to its users – whether it’s AI-generated or not.
