Optimizing TikTok ads isn’t “pause + duplicate + hope”. It’s a process structured on 4 levels: account, campaign, ad group, creative. Here’s how we apply it at Play Vertical, with examples from real accounts.
Level 1: account — tracking and attribution
Before you optimize anything, make sure the data is correct. TikTok Pixel + Events API (CAPI) active on all conversions. Adapted attribution window: 7 day click + 1 day view for e-commerce, 28 day click for SaaS/long consideration.
At Mondly, switching from pixel-only to CAPI + pixel reported 22% more conversions. Same money, same creatives, better data. All subsequent optimizations had a solid foundation.
Level 2: campaign — structure and budget
Basic rule: one campaign per objective, CBO active, minimum 5 ad groups per campaign. Minimum budget per campaign: 50x target CPA. Below that, the algorithm doesn’t have enough signal to optimize.
Smart Performance Campaign for accounts with 50+ conversions/week and 8+ tested creatives. For new or low-volume accounts, manual CBO is more controllable.
Level 3: ad group — audiences and placement
Placement: TikTok only for accounts under 10k euros/month (the rest dilutes). Automatic placement above that, with Pangle excluded.
Audiences: 3 types max per campaign. Broad (18-45, no interests), lookalike 1-3% on purchase data, retargeting 30-60 days. Interests rarely beat broad, don’t waste time on them.
Level 4: creative — where you win or lose
Minimum 5 active creatives per ad group, refresh 3/week. Evaluation metrics: hook retention 3s (target >55%), hold rate 6s (>40%), CTR (>1.5%), CVR (above account average).
If a creative has hook retention <40% after 3 days with clear budget, pause. You don’t “save” it through audience optimizations. It’s the creative, not the audience.
Automated Rules: copy them and turn them on
Three standard rules that work on 90% of accounts:
1) Pause ad if spend > 2x target CPA without conversion over 3 days.
2) Increase budget by 20% if ROAS > 2x target over 2 days.
3) Email notification if CPA grows 30% vs. the 7-day rolling average.
Optimization cadence
Daily (5 min): you check spend anomalies and automated rules. Weekly (1 hour): review creative performance, refresh 3 creatives, check competitors in Creative Center. Monthly (3 hours): full audit, postmortem, plan next 30 days.
Common mistakes that kill accounts
Over-optimization (daily changes before you have significant data), testing too many variables at once, budget too small for the algorithm (under 20x target CPA), ignoring creative fatigue. Each of these drives CPA up 20-40% in a month.
Optimization is discipline, not flashes of brilliance. Correct tracking setup, clean campaign structure, 5+ active creatives, automated rules, weekly refresh. Done consistently for 90 days, CPA drops 30-50% on most accounts. We’ve seen the pattern in every account we’ve taken over.
