Exact Match
Exact match is the tightest Amazon PPC keyword match type. It triggers only when the shopper's query matches the keyword exactly (with allowance for plurals and close variants). It is the profit centre of the account — 70–80% of healthy ad spend flows through exact-match campaigns.
Exact match is the most restrictive Amazon PPC keyword match type. An exact-match keyword triggers only when the shopper's search query matches the keyword exactly — with allowance for plurals, misspellings, and very close grammatical variants (Amazon's "close variants" expansion).
Exact match is the profit centre of a professional Amazon PPC account. The 70–80% of mature-account spend that flows through exact-match campaigns generates the majority of attributed sales at the lowest ACOS in the account — because each bid is tuned to the CVR of one specific search term, not averaged across hundreds.
What exact actually matches
Bid keyword: stainless steel water bottle. Will match:
stainless steel water bottle(exact)stainless steel water bottles(plural close variant)stainles steel water bottle(typo close variant)stainless-steel water bottle(hyphenation variant)
Will not match:
insulated stainless steel water bottle(extra word)water bottle stainless steel(order changed)steel water bottle(token removed)
Close-variant expansion is on by default and cannot be disabled in the campaign builder; if a specific variant converts poorly, add it as a negative exact.
Bidding for exact
Exact-match bids are the cleanest application of the bid formula:
Exact Bid = ASP × CVR_exact × Target ACOS
Because the keyword maps tightly to a single shopper intent, the CVR estimate is reliable (assuming sufficient click data — typically ≥30 clicks for statistical significance). The bid that emerges from this formula is the bid that hits Target ACOS exactly.
How exact-match keywords get into the account
Almost all exact-match keywords arrive through the keyword harvest loop:
- A broad or auto campaign discovers the search term.
- The Search Term Report identifies it as profitable.
- The term is promoted to an exact-match campaign at a math-derived bid.
- The term is added as a negative exact on the source campaign.
Manually seeded exact-match keywords (typed into the campaign builder from a keyword research tool) are a secondary source. They work — but the conversion rate of harvested exacts is consistently higher than that of researched exacts, because harvested terms are proven to convert for your ASIN, not just to have search volume in the category.
Branded vs. generic vs. competitor exacts
A clean exact-match campaign structure splits by intent bucket:
| Bucket | Typical CVR | Target ACOS | Role |
|---|---|---|---|
| Branded exact | 15–30% | 8–15% | Defence |
| Generic exact | 5–12% | 18–28% | Acquisition |
| Competitor exact | 2–6% | 30–50% | Conquest |
Mixing the three in a single campaign destroys the ability to bid each correctly. Keep them in separate campaigns.
Common mistakes
- Treating "exact" as "the only match type that works." Without broad and auto feeding discovery, exact stagnates — the same harvested terms compound indefinitely while category-level demand shifts unnoticed.
- Manually seeding exact keywords from third-party tools without testing. Researched keywords have category-level signal but not ASIN-level signal. Test them in broad first, harvest the winners.
- Bidding aggressive +100% top-of-search modifiers on exact. Often correct on branded exacts (CVR is uniformly high) and often wrong on competitor exacts (CVR drops on the click-through, modifier amplifies the loss).
- Mixing branded, generic, and competitor exacts in one campaign. The blended ACOS hides everything important.
