SEL/DemandSphere: branded AI Overviews surge past 80% late September

Publisher

What happened

Search Engine Land (2026-10-01): DemandSphere saw AIOs on tracked branded queries rise from ~26% early September to >80% late month, peaking 90.48% on Sep 27. Chris Long’s separate 100-brand SerpApi check found AIOs for 93 brands. Neither study measured CTR. Google announced no related change.

Why it matters

Brand visibility work must include AIO citation and messaging audits, not only classic branded organic CTR.
