Google Trends is lying to you about search demand
If you’ve been using Google Trends to decide what content to write next, you may be working with distorted data.
The problem: AI search fan-out queries can inflate topic interest inside Trends. When an AI system generates multiple sub-queries to answer a single user question, each one registers as demand. The result is a spike that looks like audience interest but reflects machine behavior, not humans looking for your content.
What to Do Instead
Stop relying on relative interest scores from Trends as a standalone signal. Cross-reference against two sources that actually reflect your audience:
- Search Console impressions and clicks: This shows real traffic your pages are already capturing or missing for a given topic.
- Keyword tools like Ahrefs or Semrush: Use these for search volume estimates that are less susceptible to AI query inflation.
- Engagement and conversion data: If the audience interest is real, it shows up in time on page, email signups, or purchases. If it doesn’t, Trends was lying.
The Bigger Picture
This is one symptom of a wider measurement problem. AI Overviews jumped from 15% to 43% of Google searches in a single year, and AI Mode visits more than doubled to 279 million by May, according to TechCrunch. As AI handles more of the query layer between users and search results, the signals that marketers built their workflows around are becoming less reliable proxies for actual human demand.
Trends still has uses: spotting seasonal patterns, comparing brand-level interest over long time horizons, or identifying regional differences. Just don’t let a Trends spike be the reason you commission a content series.
