AI Content Dominates the Modern Web: New Study Reveals Striking Trend
A recent study by Ahrefs, a leading SEO software company, has revealed that nearly three-quarters of newly published English-language web pages in April 2025 contain AI-generated content. The findings, powered by Ahrefs’ proprietary detection tool called bot_or_not, underscore the sweeping influence of artificial intelligence on the internet’s evolving landscape.
The Study: AI Is No Longer the Future—It’s the Present
Ahrefs analyzed a massive dataset of 900,000 newly created web pages, all in English and published during April 2025. By applying bot_or_not, an AI-powered classifier designed to distinguish between human-written and machine-generated text, researchers categorized pages into four distinct groups based on the proportion of AI content.
The results were eye-opening:
- 2.5% of pages were labeled “pure AI”, containing content fully generated by neural networks.
- 25.8% were exclusively human-written, showing no signs of AI use.
- A staggering 74.2% fell into the “mixed” category, where both human and AI content coexisted.

Within that mixed group, the breakdown revealed further nuance:
- 9.87% had minimal AI involvement (under 10% of content),
- 25.86% reflected moderate usage (11–40%),
- 20.50% included significant AI input (41–70%),
- and 15.51% were AI-dominant (71–99%).
Why Marketers Are Embracing AI
Ahrefs also surveyed 879 content marketers, and 87% admitted to regularly using AI tools in their workflows. Most commonly, these tools are employed for creating blog posts, email newsletters, product descriptions, and other marketing copy. Marketers cited speed, cost-efficiency, and scalability as key drivers of AI adoption.
The integration of generative AI in content creation is no longer experimental — it’s deeply embedded in digital publishing. As AI tools like ChatGPT, Claude, and Gemini become more sophisticated, their output becomes harder to distinguish from human-written content, especially in corporate environments seeking volume over voice.
What This Means for Web Content Quality
The growing presence of AI in content raises important questions about authenticity, creativity, and trust. While AI can generate readable, SEO-friendly articles at scale, it often lacks the nuance, originality, and contextual insight that define high-quality human writing.
With such a high volume of content being partially or fully automated, search engines, readers, and regulators may soon need to rethink content valuation and ranking mechanisms. Additionally, the industry could see increased demand for detection tools like Ahrefs’ bot_or_not as companies look to ensure editorial standards are upheld.
Conclusion: Human Touch Still Matters in an AI-Driven Web
The findings from Ahrefs’ research serve as a clear signal: AI is reshaping the internet faster than we anticipated. While the efficiency gains are undeniable, there’s a growing risk that the web becomes saturated with homogenized, formulaic content. Brands and publishers that prioritize authentic storytelling, editorial rigor, and strategic use of AI will be the ones who stand out in a world flooded with generative noise.
In the race for clicks and visibility, the smartest move might not be more content — but better, more meaningful content, even if it takes longer to create.
