How AI Content Detection Works (And Why It Matters for SEO)
What AI detection tools actually measure, how accurate they are, and what false positives mean for your content strategy.
What detection algorithms measure
Most AI content detectors measure perplexity (how predictable the word choices are) and burstiness (variation in sentence length — humans vary more than AI). These are probabilistic signals, not proof.
None of the current AI detection tools can definitively determine whether content was AI-generated. They produce probability scores, and false positive rates on human-written content are significant — especially for non-native English speakers or highly technical content.
Why Google doesn't use detection the same way
Google isn't primarily trying to detect AI content — it's trying to detect low-quality content. These overlap but aren't the same. Google's systems evaluate user engagement, content depth, and link acquisition patterns.
A site could publish 100% human-written poor-quality content and rank worse than a site publishing well-edited AI-assisted content that's genuinely useful.
Using WebEnture's AI Content Detector
WebEnture's AI Content Detector audits your site's content for quality signals that correlate with low-quality AI output — thin word counts, repetitive phrasing, lack of specificity. Use it to identify content needing editorial improvement, not as a binary pass/fail.
