Merge Words

A Merge Words tool (also called a keyword combiner or keyword mixer) automatically combines two lists of words or phrases to generate all possible combinations. Instead of manually typing out every permutation, you can paste two lists and instantly get every combination — for example, merging ["buy", "cheap"] with ["running shoes", "trainers"] generates "buy running shoes", "buy trainers", "cheap running shoes", and "cheap trainers" in seconds.

Using the tool is simple: (1) Enter your first list of words in List A, one word or phrase per line. (2) Enter your second list in List B, one per line. (3) Choose a separator (space, hyphen, underscore, etc.). (4) Select combination order — A+B, B+A, or both. (5) Click Merge Lists to instantly generate all combinations. You can then copy the results to clipboard or download them as a .txt file.

A keyword matrix is a structured grid that combines keyword modifiers (like "buy", "best", "cheap", "near me") with product or service terms (like "running shoes", "yoga mat", "gym bag") to generate a comprehensive keyword list for PPC campaigns. Merge Words tools are the fastest way to build a keyword matrix — what would take hours manually takes seconds. The resulting keyword list can be pasted directly into Google Ads or Bing Ads.

Merging words helps you discover long-tail keyword variations quickly and systematically. Long-tail keywords (phrases of 3+ words) typically have lower competition and higher conversion intent than broad single-word keywords. By combining intent modifiers ("how to", "best", "for beginners") with topic words ("keyword research", "on-page SEO"), you can uncover hundreds of long-tail opportunities in minutes.

Our Merge Words tool supports five separator options: Space (buy running shoes), Nothing (buyrunningshoes — useful for creating compound words or identifiers), Hyphen (buy-running-shoes — useful for URL slugs), Underscore (buy_running_shoes — useful for filenames or variable names), and Comma (buy, running shoes — useful for CSV exports). Choose based on your intended use case.

"A then B" places List A words first — e.g., "buy running shoes". "B then A" places List B words first — e.g., "running shoes buy". In PPC keyword research, both orders are useful because users search in different ways. The "Both" option generates all combinations in both orders, effectively doubling your keyword list and catching all search intent variations.

Yes — our tool includes a built-in "Remove Duplicates" option. When selected, any identical combinations that appear more than once in the output are automatically filtered out. This is particularly useful when you use the "Both" merge order, which can produce duplicate lines if List A and List B share some common words.

Yes. Once the merge is complete, click the Download .txt button to save your keyword combinations as a plain text file. Each combination is on its own line, making it easy to import directly into Google Ads Editor, Microsoft Advertising, SEMrush, Ahrefs, or any spreadsheet application like Excel or Google Sheets.
