In recent years, artificial intelligence (AI) has made great strides in replicating human skills like writing. With advanced natural language processing, some AI can now generate coherent blog posts on a variety of topics. But how does AI-generated content compare to human-written articles? Here we'll look at some key statistics and factors to consider when evaluating the quality of AI vs. human writing for blogs.

Word Count

The average human-written post is over 1,000 words, with quality blogs often reaching 1,500+ words. AI blogs max out around 1,000 words due to computational limits. Humans tend to write posts naturally of varying lengths based on the topic and amount of information they want to cover. AI tools like ChatGPT have word count limits, often capped at 1,000 words or less. This restricts how in-depth AI posts can be compared to a human writer.

Originality

94% of consumers say original blogs that cover new ideas and insights are important. Human writers draw from their unique experiences and creativity. But AI is mostly relegated to summarizing existing online data, so often lack the ability to develop fully unique perspectives. According to one study by Anthropic, only 24% of ChatGPT's content was rated as original, compared to 96% of human writing. Humans can leverage personal experiences and creativity to provide more novel analysis.

Accuracy

“Humans, but AI is gaining ground”

Ensuring information is factually correct is vital for quality blogs. One analysis by Anthropic found the error rate for AI-generated content was 8 times higher than human writing. Humans have a better understanding of nuance and context to avoid unsupported claims or mistakes. AI still struggles with common sense and reasoning in some cases. “Common sense” remains elusive!

Structure

Presenting information in a logical, easy-to-follow format is key for readable blog posts. Studies show AI-generated text tends to ramble without clear organization. Human writers plan structure ahead and intentionally guide readers through key points while AI text lacks direction. Strong intros and concluding summaries are also more natural for humans than AI.

Engagement

Human writers have a better sense of how to capture reader interest. Techniques like asking questions, using conversational tone, and adding personality through anecdotes are more authentic for human writers. While AI can mimic these styles, it often comes across as artificial. And content needs to connect emotionally to generate shares and discussion.

Research

High-quality blogs require research and citing credible sources. Humans are better able to synthesize and contextualize research to support their ideas. AI predominantly copies or paraphrases from existing sources. One study found 77% of ChatGPT content was plagiarized from the web. Humans create truly evidence-based posts.

In summary, While AI has progressed, human writers still reign supreme on key factors like originality, accuracy, structure, and engagement. Factors like depth, accuracy, structure, and research favor human writing. However, AI can complement humans by helping generate drafts faster. The future of AI writing depends on improving creativity and reasoning ability. But for businesses wanting to connect with readers, human blog writers remain ideal.
