Short answer
A keyword match type tool, also called a keyword wrapper, formats a keyword list in Google Ads notation: broad match has no symbols, phrase match goes in "quotes" and exact match goes in [square brackets]. In Google Ads Editor, negatives start with a dash, as in -[keyword]. Each keyword can have up to 80 characters and 10 words.
How to use the Keyword Match Type Tool
- Paste your keywords, one per line.
- Pick your clean-up options: lowercase, remove duplicates, remove invalid symbols, or add a prefix or suffix.
- Shorten any keyword the tool flags for going over 80 characters or 10 words.
- Copy the column you need: broad, phrase, exact or one of the three negative formats.
- Export a CSV or Editor paste file instead, with Campaign, Ad group, Keyword and Criterion Type, and import it into Google Ads Editor.
What are the keyword match types in Google Ads?
A match type tells Google how closely a search must relate to your keyword before your ad can show. There are three, and Google notes that broader match types capture all the queries of narrower match types, plus more. Each one also has a negative version that blocks searches instead.
The tool writes all six formats at once. With water heater repair as the keyword, the columns look like this:
| Column | Output | What it does |
|---|---|---|
| Broad | water heater repair | Can show on searches related to your keyword, even ones without its direct meaning |
| Phrase | "water heater repair" | Can show on searches that include the meaning of your keyword |
| Exact | [water heater repair] | Can show on searches with the same meaning or same intent |
| Negative broad | -water heater repair | Blocks searches that contain all the words, in any order |
| Negative phrase | -"water heater repair" | Blocks searches that contain the words in the same order |
| Negative exact | -[water heater repair] | Blocks that exact search only, with no extra words |
The negative rows follow Google's rules for negative keywords. The leading dash is the notation Google Ads Editor uses to mark a keyword as negative.
Close variants still apply
No match type is literal. Through close variants, all three can match misspellings, plurals, stemmings, abbreviations, reordered words, synonyms and searches with the same intent, and there is no opt-out.
Negatives are the exception, because they do not match close variants. That is why the Negative Keyword Generator spells out plurals and synonyms for you.
Keyword symbol and length rules
Google returns an error for keywords that contain invalid symbols, and it caps every keyword at 80 characters and 10 words. The "remove symbols" option strips the invalid ones, and the tool flags anything over either length limit.
| Rule | Detail |
|---|---|
| Invalid symbols | @ \ ^ , = ! ` < > [ ] ( ) % | ? ; ~ |
| Square brackets | Only as exact match notation around the whole keyword |
| Asterisk (*) | Allowed in negative keywords only |
| Allowed symbols | Ampersands (&) and accent marks, as in café |
| Ignored by Google | Periods, and plus signs except at the end of a word, as in C++ |
| Length | 80 characters or fewer, 10 words or fewer |
How do you import match types into Google Ads Editor?
Choose the Editor paste export. Each row holds one keyword in four columns: Campaign, Ad group, Keyword and Criterion Type. The Criterion Type values Broad, Phrase, Exact, Negative broad, Negative phrase and Negative exact are the match types Google Ads Editor accepts.
Keep the header row on top. Editor treats the first row as column headers and only recognizes them automatically in English. Paste the rows through Account > Import > Paste text.
If you type keywords straight into Editor instead, the inline notation works the same way, with one catch from Google's Editor help: the dash must come first. Write -[keyword] or -"keyword", never [-keyword] or "-keyword".
If your list is not split into ad groups yet, do that first with the Keyword Grouping Tool.
Common match type mistakes
- Symbols inside the keyword. A pasted line like "emergency plumber (24/7)" fails because of the parentheses. Turn on symbol removal before you export.
- Mixed case and duplicates. "Water Heater Repair" and "water heater repair" clutter the same list. Use lowercase and remove duplicates together.
- Search terms pasted as keywords. Full questions copied from a report often break the 80-character or 10-word limit. Cut them back to the core phrase.
- Treating exact match as literal. Close variants apply to exact match too, so check what you actually matched with the Search Term Analyzer after launch.
- Building local versions by hand. Use the suffix option to add "near me" to a whole list at once, then wrap the results in the match type you want.
