# AI Overviews by query length — longer queries trigger it more

> Peec's 500,000-prompt study (Apr 2026) — two-word queries get an AI Overview 64.6% of the time, rising with every word to a 89.1% peak at 11–15 words: a 25-percentage-point swing.

Query length strongly predicts whether Google serves an AI Overview. Splitting 500,000 prompts by word count (April 13–20, 2026, [full study](https://peec.ai/blog/ai-overviews-is-the-most-undertracked-ai-search-500-000-prompts-show-why)), Peec found the rate climbs with nearly every added word:

* **2 words** ("car insurance"): 64.6%
* **5 words:** 78.5%
* **6–7 words:** 84.2%
* **8–10 words:** 87.7%
* **11–15 words:** 89.1% (peak)
* **15+ words:** plateau between 87% and 91%

That is a 25-percentage-point swing between the shortest and longest queries. One-word queries are an oddity at almost 80% — even "marketing" got an AI Overview. Average across all lengths: 87% (April 2026 data).

Even keyword-style two-word queries see AI Overviews in nearly two of three searches, so short queries do not escape it. Overall coverage and growth are in [How often AI Overviews appears](/research/ai-overviews-how-often-it-appears); intent-level rates in [AI Overviews by query intent](/research/ai-overviews-by-query-intent).
