DOES TOPICAL AUTHORITY MATTER IN AI SEARCH?

Summary from the TLDR Marketing newsletter

Topical authority still matters in AI search, with data from Semrush's analysis of 50,000+ brands showing AI answers develop category owners over time. In ChatGPT's June 2026 data, only 15.2% of categories had a clear owner, leaving 89.3% of AI search demand in categories without one. Category owners also showed stronger brand search volume, organic traffic, and authority. Build depth in core topics rather than chase broad content coverage.
