Negative Exact vs Negative Phrase on Amazon: Which One to Use

Negative exact blocks your ad from showing on one specific search term and its close variants. Negative phrase blocks your ad on any search that contains the phrase, in that word order. Use negative exact for terms that are relevant but unprofitable, and negative phrase for words that make any search irrelevant to your product.

Both are available in Sponsored Products at the campaign and ad group level. There is no negative broad in Sponsored Products, so these two are your only keyword negative options.

Side-by-side comparison

Example: how each one blocks searches

You sell an adult memory foam pillow. Here is what happens with the negative 'kids pillow' added as negative exact versus negative phrase.

In this case negative phrase is the better choice because every search containing 'kids pillow' is wrong for an adult pillow. But it still misses 'pillow for kids', so you would also add a negative phrase 'for kids' or simply 'kids' after checking that the word never appears in a good search.

When to use negative exact

• A relevant search term spent money without converting. You want to stop that exact term but keep its variations, which may convert.
• You harvested a search term into an exact match campaign. Add it as negative exact in the auto, broad, and phrase campaigns so traffic goes to the exact campaign. This is the core of keyword isolation.
• A competitor brand term doesn't convert in a discovery campaign, but other searches mentioning that brand might.
• You're unsure. Negative exact is the safer default because it can't block anything you didn't specifically list.

When to use negative phrase

• A word or short phrase makes every search containing it irrelevant: a different product type ('replacement filter' when you sell the purifier), wrong material, wrong audience, or non-buyer intent ('how to').
• You see the same irrelevant modifier in dozens of search terms. One negative phrase replaces dozens of negative exacts.
• You're setting up proactive negatives before launching a broad or auto campaign.

A simple decision rule

Ask: 'Would any search containing this phrase ever be a good customer for me?' If the answer is no, use negative phrase. If the answer is yes or maybe, use negative exact.

Worked example

Your search term report for a broad match campaign on a 32 oz stainless steel water bottle shows these zero-order terms from the past 30 days:

Note 'water bottle'. It converted once at a high cost, so it isn't a negative. It is a bid problem. Read how to lower ACoS on Amazon for bid-side fixes.

How to add each type in the Ads console

1. Open the campaign (or ad group) where the waste happened.
2. Go to the Negative keywords tab. Campaign-level negatives live under the campaign; ad group-level negatives live inside the ad group.
3. Click Add negative keywords and choose Negative exact or Negative phrase as the match type.
4. Paste one term per line. Double-check the match type before saving, since it is easy to paste a list under the wrong one.
5. Save, then note the change in your log with the date and reason so you can review it later.

You can also add negatives directly from the search term view inside a campaign, which saves copying terms from a spreadsheet. For large lists across many campaigns, bulk operations spreadsheets are faster.

Building a starter negative phrase list

Before launching any auto or broad campaign, spend ten minutes on a starter list of negative phrases. Go through these categories and write down only the words that could never describe a good customer for your product:

• Other product types in your category (for a coffee grinder: 'filter', 'pods', 'beans').
• Accessories and parts if you sell the main item ('replacement', 'blade only').
• Audiences you don't serve ('toddler', 'commercial', 'industrial').
• Materials or formats you don't offer ('glass', 'plastic', 'manual').
• Research phrases ('how to', 'vs', 'review'), which you may test later but don't need on day one.

Keep this list short and confident. Anything you're unsure about should wait for search term data and, if it fails, be added as negative exact rather than phrase.

Mistakes to avoid

• Single generic words as negative phrase. A negative phrase 'bottle' on a bottle product would block nearly everything. Even 'large' or 'set' can be risky.
• Negative phrase for a harvested term. If you moved 'insulated water bottle' to exact, a negative phrase in your broad campaign also blocks 'insulated water bottle 32 oz' and every other variation, which may be exactly the discovery you want to keep.
• Adding negatives at campaign level in a campaign where another ad group needs that term.
• Forgetting that negatives in one campaign don't affect other campaigns. You must add them to each campaign where they apply.

What about negative product targets?

For auto campaigns and product targeting campaigns, you can also add negative ASINs and negative brands. These block your ad from showing on specific product detail pages or for specific brands. Use them when your search term report shows ASIN 'search terms' (ones starting with B0) that eat spend without sales. See product targeting by ASIN.

Once you know which match type to use, the bigger job is finding the terms to block. Our guides to the search term report and negative keywords walk through the weekly process.
