- ~11% of citations come from self-promotional listicles — roughly 1 in 10.
- No evidence of algorithmic correction over the 12 weeks: rates stayed stable within natural variation, so any corrections brands see are case-by-case, not systemic.
- ChatGPT filters best by far: 3.6% average — about 3× lower than Google AI Mode (10.3%) and Perplexity (10.4%). Likely drivers: ChatGPT draws from more diverse sources, uses more educational sites in this niche (7.8% vs 3.6% Perplexity, 2.5% AI Mode), and uses Zapier far less (~1% of URLs vs ~8%).
Self-promotional listicles still get cited — about 1 in 10 citations
Peec’s 232,000-citation study (Dec 2025–Feb 2026) — ~11% of AI search citations come from self-promotional listicles; ChatGPT filters best at ~3.6% vs ~10% for Google AI Mode and Perplexity.
AI search has not solved the self-promotion problem. Peec analyzed 232,000 citations across 13,000 listicles over 12 weeks (December 2025–February 2026) on six platforms in the software-review niche (full study). A self-promotional listicle is a “best of” roundup where the publishing brand ranks its own product on top.
