Keyword Combiner
Paste up to four lists of words, such as modifiers, products and locations, and get every combination instantly. Wrap them in broad, "phrase", [exact] or negative match syntax, then copy the list or download a CSV ready for your ad campaign.
Last updated:
Adds List 1 + List 3, List 2 + List 3 and so on, keeping list order.
e.g. 'running shoes buy' as well as 'buy running shoes'.
How to use the Keyword Combiner
- Fill List 1 with the first part of your keywords, one per line (for example modifiers such as buy, cheap, best).
- Fill List 2 to List 4 with the next parts: product names, features, audiences or locations. Empty lists are skipped.
- Choose match types: broad, phrase, exact and, if you need a negative list, negative.
- Set options such as shorter combos, every list order, the joining character and letter case.
- Click Combine keywords (results also update as you type), then use Copy results or Download CSV to paste them into your ad platform.
How keyword combinations are counted
The number of combinations is the product of the list sizes, and each match type you tick adds one more copy of the list. Empty lists are skipped, and duplicates (for example the same phrase typed twice) are removed before counting.
| Lists filled | Example sizes | Combinations | With broad + phrase + exact |
|---|---|---|---|
| 2 lists | 5 × 4 | 20 | 60 |
| 3 lists | 5 × 4 × 3 | 60 | 180 |
| 4 lists | 5 × 4 × 3 × 2 | 120 | 360 |
| 3 lists, every order | 5 × 4 × 3 × 6 orders | 360 | 1,080 |
Match type syntax at a glance
| Match type | How it is written | Typical use |
|---|---|---|
| Broad | running shoes | Reach and discovery, usually paired with smart bidding and a solid negative list |
| Phrase | "running shoes" | A balance of reach and control; the search must include the meaning of the phrase |
| Exact | [running shoes] | Your best-performing, high-intent terms where you want tight control over cost |
| Negative | -free | Blocking searches you never want to pay for, such as free, jobs or DIY |
Tips for building better keyword lists
- Put one idea in each list. A common pattern is modifier + product + qualifier, such as cheap + hiking boots + for women.
- Keep lists short and relevant. Ten modifiers times ten products times ten towns is already 1,000 keywords; weak combinations dilute your quality and budget.
- Read the output before uploading. Delete combinations that do not make sense as a real search (for example "free buy shoes").
- Group by theme. Upload combinations that share a product into the same ad group so ad copy can match the search closely.
- Add negatives early. Combine words like free, used, repair or jobs with your product to build a negative list in seconds.
Frequently asked questions
What does a keyword combiner do?
It joins each keyword in one list with each keyword in the next list, producing every combination. Three modifiers, two products and two locations give 3 × 2 × 2 = 12 keywords. It is the fastest way to build large, consistent keyword sets for search ad campaigns.
What is the difference between broad, phrase and exact match?
In Google Ads, a broad match keyword is typed as-is and can show ads for searches related to its meaning. Phrase match is written in quotes, "running shoes", and matches searches that include the meaning of the phrase. Exact match is written in square brackets, [running shoes], and matches searches with the same meaning or intent. Microsoft Advertising uses the same symbols.
How many keywords can I combine?
The tool creates up to 10,000 keywords per run, counting every match type. If your lists would produce more, the output is capped and a notice is shown; split the job into smaller lists or turn off the every-list-order option.
Is there a length limit for Google Ads keywords?
Yes. A Google Ads keyword can contain at most 80 characters and 10 words. The combiner counts both and warns you how many generated keywords go over either limit so you can remove them before uploading.
What do the shorter combos and every list order options do?
Shorter combos also join any two or more lists while keeping their order, so buy + running shoes appears alongside buy + running shoes + online. Every list order adds permutations such as running shoes buy, which helps when people type words in different orders.
Can I make a negative keyword list?
Yes. Tick Negative to output each combination with a leading minus sign, the format used when pasting negative keywords in many ad editors. Wrap negatives in quotes or brackets yourself if you need phrase or exact negatives.
Is broad match modified (+keyword) still available?
No. Google Ads stopped allowing new broad match modifier keywords in 2021 and folded that behaviour into phrase match. If an older tool asks for +word syntax, use phrase match instead.
