Our Mid-August Signup Spike Came From ChatGPT — Not Google
GA4 for Aug 8–20 2026: ChatGPT drove 27 newUsers and most tracked signups, while GSC had ~9 clicks. How we plan to recreate the spike without paid ads.
In short: Between 14–17 August 2026, OBRI saw a real signup spike. GA4 attributes the quality side to ChatGPT (chatgpt.com / AI Assistant: 27 new users, 7 of 12 tracked signup_completed). Search Console had only ~9 clicks in the same Aug 8–20 window. To recreate it, we double down on citability of / and /en — not on another thin SEO package.
I build OBRI, a CRM for independent tutors. After the mid-August jump in profiles, we pulled GA4 + GSC for 8–20 August 2026 instead of guessing.
What the spike looked like
| Date | GA4 new users | Note |
|---|---|---|
| Aug 8–12 | ~0–1/day | Quiet baseline |
| Aug 14 | 10 | ChatGPT + organic appear |
| Aug 15 | 11 | Direct jumps (often stripped referrers) |
| Aug 16 | 16 | ChatGPT peak day (~8 new from AI) |
| Aug 17 | 19 | Absolute peak |
| Aug 18 | 1 | Dip |
| Aug 19–20 | 9 / 13 | Partial rebound |
Window totals (GA4): 84 new users, 177 sessions, 59 signup_started, 12 signup_completed. Supabase weekly profile counts for weeks of Aug 10 / Aug 17 (19 / 17) line up with that mid-month burst — GA4 undercounted OAuth completions until an Aug 18 tracking fix.
Channel ranking (evidence, not vibes)
| Source / medium | New users | Tracked signup_completed users |
|---|---|---|
| (direct) / (none) | 44 | 2 |
| chatgpt.com / ai-assistant | 27 | 7 |
| google / organic | 13 | 2 |
| saashub.com / referral | 0 | 0 |
Direct is the largest volume bucket. ChatGPT is the best conversion evidence. In practice those often overlap: in-app browsers and copy-paste links strip the referrer.
SaaSHub was live around Aug 19 in our directory runbook — after the peak. Its GA4 sessions looked like crawler noise (/dashboard, ~0 new users).
GSC for the same window: roughly 9 clicks / ~104 impressions. Organic helped a little. It did not create thirty-plus weekly profiles.
Where ChatGPT landed people
/— homepage/en— English product page- A long tail of templates / alternatives / auth
So the play is not “rank 400 blog posts.” It is: make the product pages quoteable, then keep publishing measurement notes models can cite.
Repeat playbook (what we are doing next)
- Homepage citability — keep a visible “In short” / FAQ on
/and/en(what OBRI is, free plan, not a marketplace). - Founder measurement posts — real windows, real channel tables (this article is one).
llms.txtfreshness — map this post and the product URLs.- Third-party corroboration — Reddit / niche groups / filled directory profiles so models see the brand off-site.
- Self-reported “how did you hear?” on signup — so ChatGPT and dark social stop disappearing into Direct.
- Do not wait on GSC for this motion — AI discovery showed up before Google clicks did.
What I am not claiming
- Nineteen new users in a day is not product-market fit.
- Direct is not “all ChatGPT.”
- Directories are useless forever — they were just not this spike.
- We should abandon Google SEO. Equity after the obricrm.com migration is still settling.
I am claiming this: for a niche tutor CRM in 2026, one week of ChatGPT citations to clear product pages beat a month of thin Search Console activity. That is where we reinvest.
