I just hit Day 15 of an AI-driven Build-in-Public push for Tasteck , a vertical SaaS I run. Sharing the actual numbers because most "Build-in-Public works for SEO" claims you see online lack data.

TL;DR — 15 days, 4/24 → 5/8

Metric (28-day total) 4/23 baseline 5/8 (Day 15) Change

Clicks 19 141 7.4x

Impressions 281 2,705 9.6x

7.4x clicks / 9.6x impressions in 15 days.
