How AI Content Kills Your SEO (16-Month Experiment)

AI content SEO experiment results — does AI-generated content actually rank on Google long term, or does it collapse after the initial boost?

We ran a 16-month SEO experiment across 20 websites and 2,000 AI-generated articles to find out. Early on, traffic exploded — but by month three, rankings dropped hard. The surprising part? A later test in March 2026 revealed a completely different use case for AI content that actually boosted performance.

If you’re an SEO, content marketer, or agency, this directly impacts how you scale content, use AI tools, and plan long-term strategy.

In this video, we break down:
– What actually happened in a 16-month AI content experiment
– Why rankings collapse (and what Google is actually evaluating)
– How AI content can still work — if you use it the right way
