That search term you negated last week? Yeah, it's back in a new disguise.

And you've wasted $3k so far (and counting).

You're selling premium yoga mats at $79. Your target audience? Wellness-focused women who value quality over price.

But Amazon doesn't care.

Over 4 months, you're paying for "cheap" in 49 different variations—"cheap yoga mats" ➡️"cheap workout mats yoga" ➡️"affordable cheap exercise mats"...

Each variation gets 15-30 clicks before you notice. 0 orders.

You've burned $3k showing your premium mat to bargain hunters who will never buy.

The problem? You used Broad/Phrase match. But you didn't filter out waste words.

The fix? Negate the waste words—"cheap," "discount," "affordable," "budget"—before they spawn variations.

What becomes possible:

Immediate drop in wasted clicks—budget reallocates to better traffic automatically.

️Campaign metrics improve—Amazon's algorithm notices better engagement and starts favoring your ads.

️Cleaner data—you can actually see patterns in what's working.

New campaigns launch pre-protected—waste words can't infiltrate them from day one.

Kill the waste words once. Stop the $3k bleed.

If you'd set this up 4 months ago, that $3k would still be in your account.

Takes 3 minutes. Here's How:

Step 1: Find Your Waste Words

1. From your Scale Insights account, navigate to Ads Insights.

2. Select Main words.

3. Apply the filter "Unique Word with 0 Sales" and a lookback period of 60 days. Click Update.

4. You'll see every word bleeding budget with zero return. (This is where you'd find "cheap" with 49 variations draining $3k.)

5. Here's a real example: "transparent" = 54 clicks, $25.15 wasted, 0 orders.

Small individually. Multiply this across 49 waste words = your $3k bleed.

Step 2: Auto-Kill Them

1. Navigate to Automation > Negative word rule.

2. Select the Negative word rules tab. Select the [ASIN] Remove 0 Conversion preset rule. (Kills any word at 25 clicks with 0 orders—adjust this later if needed.)

3. Assign it to your Broad/Phrase ad groups → Click Assign.

✅ Done. Auto-negation is now active.

Waste words get killed at 25 clicks—before they spawn 47 variations.

Want to kill waste words instantly instead of waiting for 25 clicks?

Blacklist them manually:

1. In that same Main Words view from Step 1, toggle the Blacklist button on waste words like "cheap," "discount," "affordable."

2. Navigate to Automation > Blacklist/whitelist rule > Blacklist/whitelist rules tab.

3. Click Edit for your ASIN → Confirm the words appear in Negative Phrase List.

4. Select the Broad/Phrase ad group(s) to apply the blacklist to and select Enabled. Click Assign.

✅ Done. This prevents them from wasting even one click.

What Just Happened:

✔ You stopped waste words before they multiply

✔ Your budget now goes to buyers, not bargain hunters

✔ New campaigns launch pre-protected from day one

No more $3k bleeds. No more whack-a-mole.
