We analyzed 3,900 articles from the blogs of 246 Fortune 500 companies. Our AI detector examined the text of reviews to find how much content was likely generated by humans or AI.
Almost 11% of articles at official blog sites are suspected of being AI generated
The articles on the blogs of Fortune 500 companies are mostly human written. Using our AI detector, we found that 10.86% of articles reviewed in November 2023 were likely to be AI-generated. However, there was a lot of variation in how much potential AI content was found on different companies’ sites, ranging fully from zero to 100%. A closer examination was made of the 20 companies for which there were at least 20 different articles in the dataset, to a high of 72 articles. Those individual sites ranged from a low of 1.56% to a high of 63.16.%.

Higher Word Counts Less Likely to Have AI-Generated Content
A strong negative association was found for the number of words in the article and its odds of rating a high chance of being written by generative AI. The longer the article, the more likely it appeared to be written by humans. The shorter the article, the more likely it appeared to be written by AI. Dividing the dataset in half at the median 3,723 words created a stark difference, with 18.8% of the shorter articles examined appearing to be AI-generated, compared to only 3.3% of the longer articles. Shorter blog entries were 5.7x more likely to rate as AI-generated than the longer ones.
This finding has a certain resonance with an Originality.AI study on Sports Illustrated articles, where shorter, less substantive sections of articles, like the introduction, were more likely to be potentially written by AI as compared to the longer bodies and actual reviews in articles. This finding suggests that generative AI be more likely used for shorter discussions, while longer articles, which might have more details and be more in-depth, remain the creation of human authors.
AI-generated content might be in wide use for some Fortune 500 blogs, while others appear to use none. Questions that remain to be answered include if the writing staff or the audience is aware of the AI content on these sites? Should they be? Is a feature article less interesting if it is generated by AI? Do readers care if shorter reporting is AI written? The controversy around Sports Illustrated’s use of AI-generated articles suggests that transparency, or at least not creating names, photographs, and biographies for non-existent authors, might be more acceptable to most people.
With our proprietary Originality.ai AI detection tool, we analyzed the presence of AI in health and wellness reviews across key consumer industries — baby formula, skincare, and health supplements. These are our findings.
