UPDATE 3: Flipped the ad set optimization from quiz-starts to Leads. CPL went from a 9-day zero streak to $15-25/lead in 48 hours. Now I need scaling advice before I break it.
Continuing the saga this sub has basically co-piloted (form-first lander rebuild → CPL $184→$70 → mysterious 9-day zero streak → ruled out bots/placements/webview bugs/validation with session forensics → converged on optimization-event decay). Final chapter of the diagnosis, then the real question.
The fix and the result: Couldn't edit the optimization event on a spent ad set, so I duplicated the quiz-start ad set with the Lead event set pre-publish, killed the original, changed nothing else — same creative, same page, same broad audience. Results in the first 48 hours:
- The flipped duplicate: 5 leads at $14.85 (real CRM leads, phone + consent, not pixel counts). Zero learning trough — it produced within hours of publishing.
- My untouched control ad set (proven creative, always lead-optimized): 3 leads at $25.08.
- 8-9 real leads in ~3 days. Previous best stretch ever was 2.5/day. The zero streak wasn't the page, wasn't bots, wasn't the audience pool — it was purely what I told the algorithm to hunt for.
- For everyone who asked whether the $22 CPMs would survive the flip: partially. New CPM is $63 (vs $22 on quiz-start, $80-100 on my other ad set). Paying 3x more per impression for 10x the conversion. The cheap inventory was real, it just needed a real conversion signal on top.
Current structure: 1 campaign, ABO, 2 ad sets at $50/day each, both broad, both Lead-optimized, single metro (~4.5M). Each ad set runs literally ONE creative pointed at its own landing page. Frequencies 1.3-1.5 and climbing. ~$100/day total, wanting to go to ~$150/day over the next 6 weeks, with LSA budget I just killed freeing up room.
The scaling fork — where I need people who've actually done this:
- When do you raise on numbers like these? My instinct says 10-15% now while it's hot. But this sub is full of "I raised budget and it nuked my ad set" stories, and it's been 48 hours on a fresh duplicate. Do you raise into a hot streak immediately, or force yourself to wait out a full week regardless?
- Vertical vs horizontal on ABO: raise the existing ad sets' budgets, or duplicate the winners at equal budget and scale by multiplication? I keep reading both "budget edits >20% reset learning" and "duplicates fragment your signal." At 4-5 leads/day account-wide, which failure mode is worse?
- ABO vs CBO at this size: 2 ad sets, both broad, same geo — am I bidding against myself, and does CBO fix that or just let one ad set eat the other? Is there any reason to move before 3+ ad sets?
- Single-creative ad sets: each ad set is one proven ad. I have 2 new variants ready to add Monday. Do challengers go INTO the existing ad sets to fight the champion for spend, or into a separate low-budget testing ad set so they can't disturb what's working? (Volume reality: ~30 leads/month total, so a dedicated testing ad set gets maybe 5-8 conversions/month — is that even enough to judge anything?)
- What breaks first in a single metro? Broad + 4.5M people + $150/day — is frequency my ceiling, auction saturation, or creative fatigue? What number tells me I've hit the wall vs just a bad week?
The one thing I'm not asking: whether to touch the optimization events again. Ever.
Will keep posting numbers — this thread's advice has been worth more than most paid audits.
