In the competitive content market, using AI-written content might pose several risks. AI models such as Chat GPT have led to an increase in the usage of machine-generated content.  However, your AI-produced content might match with others. The information you extract from an AI may be inaccurate and shallow. While AI tools are a great time saver, these drawbacks can cost you a lot as most businesses prefer publishing unique, updated, and relevant content.

How Does AI Content Impact Your SEO Ratings?

The one Google algorithm you should keep in mind is the SEO of your content which is determined by the right keywords, citation listings, meta tags, readability, domain links, accessibility etc. 

Google, in its recent report named “Google Search's guidance about AI-generated content”, claims that it prefers original content which is high quality and demonstrates the following features - experience, expertise, trustworthiness, and authoritativeness. 

While Google remained unchanged in its policy about how the quality of the content is more important than how the content is produced, the company was also transparent that using automation or AI to generate content to manipulate SEO ranking in the search results is a direct violation of their spam policies. 

In a nutshell, Google rewards the production of original, high-quality content and using AI responsibly is not against its guidelines. However, this does not take away the anxiety of business owners about their SEO rankings. So, here is a comprehensive list of AI tools to help you detect any AI-generated content that might pull down your SEO rankings.
