From Launch to Scale: How to Set Target ACoS & TACoS at Every Stage of a Product’s Life on Amazon

Most sellers talk about “good ACoS” as if it’s a single magic number. In reality, your ideal ACoS and TACoS change over time.

A product you just launched does not need the same ACoS as a mature bestseller. If you try to force every product into the same target, you either:

• Kill growth too early by cutting bids aggressively, or
• Waste profit on mature products by overspending on ads.

In this article, we’ll walk through how to set realistic ACoS and TACoS targets for each stage of your product lifecycle:

• Pre-launch & launch
• Early growth
• Mature / stable phase
• Decline or repositioning

We’ll also look at how to connect day-to-day optimization decisions (bids, budgets, keywords) to these stage-specific targets.

ACoS vs TACoS: Quick Recap

Before we dive into lifecycle strategy, let’s quickly recap:

• ACoS (Advertising Cost of Sales) = Ad Spend ÷ Ad-attributed Sales
  → Tells you how efficient your ads are by themselves.
• TACoS (Total Advertising Cost of Sales) = Ad Spend ÷ Total Sales (Ad + Organic)
  → Shows how much your entire revenue depends on ads.

Shortcut:

• ACoS = campaign-level performance
• TACoS = business-level dependence on ads

Both are important, but you’ll use them differently at each product stage.

Stage 1: Pre-Launch & Launch

Goal: Visibility, Reviews, Ranking – Not Profit

When you launch a new product, your main problem is not ACoS – it’s invisibility.
You have:

• Few or no reviews
• No organic rank
• No sales history

At this stage, expecting a low ACoS is unrealistic. Instead, focus on:

• Getting clicks on your most relevant keywords
• Generating consistent daily sales
• Building review count & social proof

Typical Targets in Launch

• ACoS: Often higher than break-even, sometimes even 120–150% of break-even ACoS for the most important (strategic) keywords.
• TACoS: Usually high and unstable at the start, because nearly all sales come from ads.

Example:

Break-even ACoS for your product is 25%.
In launch, you might be okay with 35–45% ACoS on key terms while you build rank and reviews.

Practical Actions in Launch

• Bid aggressively on high-intent, highly relevant keywords.
• Use exact and phrase match for main converting terms, plus broad for discovery.
• Accept that some campaigns will run at a loss as “ranking campaigns”.
• Watch CTR and conversion rate closely: quickly cut irrelevant terms, keep strategic ones even at higher ACoS.

At this point, ask yourself less:
“Is this campaign profitable?”
and more:
“Is this campaign helping me rank, get reviews, and generate momentum?”

Stage 2: Early Growth

Goal: Stabilize Performance & Move Towards Profitability

After launch, your product hopefully has:

• A few reviews
• Some repeating sales
• Early organic placements on important keywords

You still want growth, but now profit becomes more important.

Typical Targets in Early Growth

• ACoS: Aim to move closer to break-even while still pushing volume.
• TACoS: Start tracking it weekly. You want to see it gently trending down, even if slowly.

Example:

Break-even ACoS: 25%
Launch ACoS: 40%
Early growth target: 25–30% on main campaigns, lower on branded/defensive terms.

Practical Actions in Early Growth

• Start segmenting campaigns:
  • Ranking / aggressive campaigns (higher ACoS tolerance)
  • Profit-focused campaigns (tight ACoS control)
• Lower bids on keywords that no longer need top-of-search all the time to generate sales.
• Promote high-performing search terms from auto/broad into exact match “performance” campaigns.
• Start testing placements (Top of Search vs Product Pages) and reduce multipliers where ACoS is too high.

Here, your mindset shifts to:
“How do I keep growth, but stop burning unnecessary ad spend?”

Stage 3: Mature / Stable Phase

Goal: Maximize Profit, Protect Rank, and Lower TACoS

At this point, your product has:

• Solid review count
• Stable daily sales
• Good organic ranking on core keywords

Now, TACoS becomes your main compass.

If your TACoS is dropping or staying low while revenue stays stable or increases, that means:

• Organic sales are carrying more of the load
• You’re less dependent on ads
• Your brand and listings are doing their job

Typical Targets in Mature Phase

• ACoS: Often below break-even for most performance campaigns.
• TACoS: Ideally in a low range (e.g., 5–10%), depending on category and margins.

Example:

Break-even ACoS: 25%
Mature phase target ACoS: 15–20%, especially on branded and high-converting terms.
TACoS stable around 5–8%.

Practical Actions in Mature Phase

• Tighten bids on poor or mediocre performers:
  • Increase bids only on keywords with excellent conversion and low ACoS.
  • Lower or pause keywords with high spend and low return that don’t support core positioning.
• Use branded campaigns to protect your brand name at very efficient ACoS.
• Shift some budget from expensive generic terms to:
  • Branded
  • Long-tail, highly relevant keywords
• Regularly check search term reports and remove bleed:
  • Irrelevant queries
  • Super generic, expensive terms that don’t convert

Now your main question becomes:
“How do I keep my rank, protect my territory, and pull more profit out of each sale?”

Stage 4: Decline or Repositioning

Goal: Clear Stock or Redefine Strategy

No product stays at peak forever. Maybe:

• New competitors arrived
• The product is aging out
• A new version is coming
• Seasonal demand dropped

Here, you’ll choose between harvesting profit, clearing inventory, or repositioning the product.

Option A: Milk Profits

If the product still sells decently with no major restocks planned:

• ACoS: Push as low as possible while maintaining acceptable volume.
• TACoS: Can be very low if organic rank is still holding.

Actions:

• Cut all non-essential generic keywords.
• Focus on branded terms and highest-converting search terms only.
• Lower bids on everything else, even if that means losing some impressions.

Option B: Clear Stock

If you just want to liquidate inventory:

• ACoS: You might allow ACoS to rise as long as overall profitability across remaining units makes sense.
• TACoS: Less important; focus on cash flow and space.

Actions:

• Increase bids and/or discounts and coupons to push volume.
• Use Sponsored Products + Deals to move leftover stock.
• Accept temporarily higher ACoS if it means faster sell-through.

Option C: Reposition

If the product still has potential but needs a new angle:

• Rework main images, title, bullets, A+ content.
• Shift targeting to new keyword clusters (e.g., different use-cases, problem/solution keywords).
• Temporarily treat campaigns like a mini relaunch with higher ACoS tolerance while you collect new data.

How to Connect Daily Optimization to Lifecycle Targets

Knowing your “stage” is great, but it only helps if it changes how you optimize. Here’s how to link lifecycle logic to daily decisions.

1. Define Targets per Product (Not Only per Account)

Instead of one generic “target ACoS” for the whole account, define:

• Target ACoS for launch products
• Target ACoS for growth products
• Target ACoS for mature products

Example structure:

• Launch products: target ACoS = 35–45%
• Growth products: target ACoS = 25–30%
• Mature products: target ACoS = 15–20%

Then apply these targets:

• At campaign level and
• At keyword level (especially for high-volume terms)

2. Use Rules Based on ACoS & Conversion Rate

For each stage, you can use simple rules like:

• If ACoS > target ACoS and enough clicks (e.g., 20–30+) → lower bid by X%.
• If ACoS < target ACoS and good conversion → increase bid by Y%.
• If zero sales after Z clicks and you’re not in launch mode → cut bid sharply or pause keyword.

In launch, you might be more forgiving.
In mature phase, you should be ruthless with waste.

3. Watch TACoS Trends Monthly

ACoS reacts quickly.
TACoS moves slower — but it tells you if your organic engine is improving.

Ask each month:

• Is TACoS going down while sales stay stable or grow?
• Are we too dependent on ads for this product?
• Is increased spend actually lifting total revenue, or just reshuffling sales from organic to paid?

If TACoS constantly climbs, you’re buying sales without building lasting momentum.

Common Mistakes with ACoS & TACoS by Lifecycle

• Expecting launch products to hit mature ACoS levels
  → You underbid, lose impressions, and the product never takes off.


• Never relaxing bids after growth phase
  → You keep “launch-style” spend on a product that doesn’t need it anymore and bleed profit.


• Ignoring TACoS completely
  → You think you’re scaling because ad revenue is up, but total revenue is flat and you’re just cannibalizing organic sales.


• Same optimization logic for every product
  → No difference between a brand-new ASIN and a 2-year bestseller in terms of targets and bid aggressiveness.

---

Conclusion

There is no single, universal “good ACoS”. There is only the right ACoS and TACoS for your product at its current stage.

To recap:

• Launch: Forget about perfect ACoS; focus on visibility, ranking, and early reviews.
• Early Growth: Move closer to break-even while maintaining momentum.
• Mature: Prioritize profit and TACoS; protect rank and squeeze out margin.
• Decline / Reposition: Either harvest profit, clear stock, or reinvent the angle.

If you align your targets, bids, and budget with where each product is in its lifecycle, your advertising becomes a strategy, not just a series of random bid changes.
