What Type of Content Gets Cited by
OpenAI ChatGPT Search in March 2026?

Based on 15,430,109 classified Promptwatch citations from Feb 24 - Apr 5, 2026. The chart shows the percentage breakdown of citation content types per day. Only citations with a classified content type are included.

What this means for you

In March 2026, product pages are ChatGPT Search's most cited format, averaging around 18% of daily citations and trending toward 19% by early April, ahead of listicles at roughly 16% and news articles at 9%. Compared to earlier in the year, ChatGPT has shifted further toward citing brand-owned commercial pages as primary sources.

The clearest riser is comparison content, which nearly doubled its share over the period (from about 1.8% to 3.5%), alongside a steady climb for social posts. When buyers ask ChatGPT to weigh options, it increasingly answers with dedicated comparison pages.

How to act on it

  • Treat your product pages as citation assets as well as conversion pages: structured specs, transparent pricing, and up-to-date availability give ChatGPT concrete facts worth quoting.
  • Add head-to-head comparison content ("X vs Y") to your roadmap now. It's the fastest-growing format in this dataset, and there's still relatively little competition for those citations.
  • Pair every product launch with a listicle-friendly angle; getting included in third-party "best of" roundups remains one of the most reliable routes into ChatGPT answers.
