Keyword Match Types and Negative Keywords in Google Ads

[{{INSERT IMAGE: a clear diagram of the three match types — broad/phrase/exact, with example search queries for each type, dark theme, blue accent}}]

Picture this: you set up the keyword “buy running shoes”, and your ad shows for the query “how to clean running shoes” — the traffic arrived, the money was spent, and there is no conversion. That is the classic consequence of choosing the wrong keyword match type. Let us look at how to avoid it.

What keyword match types are

A match type is the keyword targeting setting that determines how closely a user's search query has to align with your keyword for Google Ads to show your ad. Google Ads (and Microsoft Ads) offer three main options: broad, phrase, and exact match — each with its own balance of reach and control.

Broad match

Broad match is the most flexible type. Your ad can show for related queries, synonyms, word variations and even queries with no direct textual overlap with your key phrase, as long as the algorithm considers them relevant to the user's intent.

Formatting: no symbols at all, just the word or phrase — buy running shoes.

Example: the keyword “buy running shoes” in broad match can trigger an ad for the query “where to order athletic footwear”.

This gives you maximum reach, but it demands serious control through negative keywords and close cooperation with Smart Bidding — automated bidding strategies are practically mandatory today for using broad match effectively.

Phrase match

Phrase match is written in quotation marks: "buy running shoes". The ad shows if the query contains that entire phrase in the same word order, although additional words may appear before or after the phrase.

Example: the query “where to buy running shoes cheap” will match, while “running shoes buy footwear” will not, because the word order is broken.

Phrase match is the golden middle ground between reach and control, and the default type for most well-structured campaigns.

Exact match

Exact match is written in square brackets: [buy running shoes]. Despite the name, exact match also covers close variants — singular and plural forms, misspellings, and rephrasings with the same intent.

Reach here is the narrowest and control is the highest. It is the right choice for brand queries, high-margin products, and keywords with clear commercial intent.

How to choose the right match type

A practical approach is to structure your match types by sales funnel stage:

• Top of the funnel (awareness, research) — broad match with active monitoring of the search terms report
• Middle of the funnel (comparison, evaluating options) — phrase match
• Bottom of the funnel (purchase readiness, brand queries) — exact match

What negative keywords are

Negative keywords are words or phrases that prevent your ad from showing for particular queries. While regular keywords define WHICH queries should trigger your ads, negative keywords define which queries should NOT. In essence this is negative targeting: you are not adding an audience, you are cutting away everything irrelevant.

How match types work for negative keywords

There is an important difference from the logic of regular keywords here. The negative keyword -free as a broad negative blocks any query containing the word “free” in any order — for example “shoes free” or “free shoe delivery”. However, it does not automatically block related forms of the word, such as “freebie” — that is a separate word which has to be added as a separate negative keyword.

If you need to block a specific phrase rather than a single word, use a phrase negative: -"free delivery" blocks queries containing that exact phrase in that order, but it will not block “delivery free shoes”.

The main difference from regular keywords: for keywords, a narrower type (exact) narrows the reach of your impressions, while for negative keywords a narrower type (phrase or exact) narrows the reach of your blocking — meaning it lets more queries through than a broad negative would. In Google Ads these exclusions can be set at the campaign level, the ad group level, or as a shared negative keyword list.

Common mistakes with negative keywords

Using broad match only, without a systematic negative keyword list — a waste of budget on irrelevant clicks from related but off-target queries. It is the fastest way to burn through a test budget in Google Ads.

Ignoring exact match for high-value brand queries — competitors can intercept traffic on your own brand keyword.

Negative keywords that are too broad, unintentionally blocking relevant traffic along with the off-target kind.

No regular review of the search terms report (Search Terms Report) — your negative keyword list should grow continuously, not just once at campaign launch.

A practical tool for working with match types

Instead of formatting every keyword manually in three variants, you can use the PPC-Hub Keyword Match Type Generator — the tool instantly generates columns with broad, phrase, and exact match, with quotation marks and square brackets added automatically. For working with ready-made exclusion lists, there is also a basic negative keyword list for Google Ads.

Summary

Combine match types by funnel stage instead of applying a single type across the whole account. Paste in your keyword list and copy the ready-made formatting variants for Google Ads Editor or bulk upload — it saves hours of manual work compared with formatting every keyword by hand.
