Why TACOS — Not ACOS — Is the Right Launch Metric
During a launch, your organic revenue is near zero. So ACOS (Ad Spend ÷ Ad Revenue) will always look terrible because the denominator is small. A 90% ACOS on a new product might be completely acceptable if your Total ACOS (Ad Spend ÷ Total Revenue including organic) is trending down, because it means you're building organic rank that will compound long after the launch spend reduces.
The launch goal isn't to hit a profitable ACOS in week one. It's to build enough conversion velocity on your target keywords to earn organic rank — at which point you can reduce ad spend and watch organic revenue hold or grow.
"On a skincare launch Bidvista managed, ACOS at day 30 was 71%. TACOS was 34% and falling. By day 75, TACOS had dropped to 28% and 12 keywords were ranking page 1 organically. That 71% ACOS in month 1 was the right investment."
Pre-Launch Checklist (Week -2 to 0)
PPC cannot fix a bad listing. Before you spend a rupee, these must be true:
- Main image passes the thumb test — clearly communicates the product at thumbnail size
- Title includes primary keyword naturally in first 80 characters
- Bullet points address the top 3 customer concerns and include secondary keywords
- A+ Content live (if Brand Registry enabled) — significantly improves CVR
- Vine enrollment active if eligible — first reviews dramatically improve CVR
- Keyword research complete — primary targets, secondary targets, and 150+ pre-load negatives ready
Days 1–21: Velocity Phase
Budget allocation: 40% auto (discovery), 35% exact match (target keywords), 25% broad/phrase (keyword testing).
In the first three weeks, you're optimizing for conversion velocity, not ACOS. Your target keywords should have your highest bids — you want to win those auctions consistently to build rank signals. Don't be afraid of top-of-search placements even at premium cost; the rank signal from top-of-search conversions is significantly stronger than rest-of-search.
Add negatives every 3 days in this phase (not weekly — the data moves fast during a launch). Monitor daily and pause any ad group spending heavily with zero conversions after 30–50 clicks.
Days 22–45: Optimization Phase
By week four you should have enough data for real bid optimization. Apply the Target ACOS × CVR × Price = Target CPC formula to each keyword using launch-phase CVR data. Promote any converting terms from auto and broad into exact match campaigns. Pause or significantly reduce bids on zero-converting terms.
Check organic rank weekly using Brand Analytics or Helium 10 Rank Tracker. You should start seeing movement on your primary keywords by week 4–6. If you're not seeing any rank movement by day 30, the issue is either insufficient budget, below-average CVR (listing problem), or you targeted keywords that are too competitive for the current review count.
Days 46–60: Consolidation Phase
If rank has moved, begin reducing bids on keywords with strong organic positions. The goal is to let organic take over the volume while PPC fills in the gaps. Calculate the "organic-adjusted ACOS" — if a keyword ranks position 2 organically, it will capture clicks even without PPC; your PPC bid on that term should decrease accordingly.
By day 60, you should have a clean picture of: which keywords have earned organic rank, which need continued PPC support, and what the steady-state budget looks like. This becomes the brief for the ongoing management phase.
Launch Phase Summary
- Days 1–21: Velocity. High bids on targets. Daily negative additions. Optimize for rank, not ACOS.
- Days 22–45: Optimization. Apply CPC formula. Promote winners to exact. Pause losers.
- Days 46–60: Consolidation. Reduce bids where organic rank exists. Set steady-state budgets.
- Metric to watch: TACOS trend (should fall from launch high to sustainable steady-state)
- Secondary metric: Organic rank movement on primary keywords week-by-week
