Frequently asked questions
What is a keyword combiner?
A keyword combiner is a tool that takes multiple lists of words or phrases and generates every possible combination between them (a cartesian product). For example, combining 'best, cheap' with 'running shoes, sneakers' produces 'best running shoes', 'best sneakers', 'cheap running shoes', and 'cheap sneakers'.
How many keyword lists can I combine?
This tool supports up to three lists. List A and List B are required, and List C is optional. With three lists of 10 keywords each, you generate 1,000 unique combinations instantly.
What separator should I use?
For most SEO and content purposes, use a space separator — this produces natural-sounding keyword phrases. Use hyphens for URL slugs, underscores for file names or technical identifiers, and plus signs for Google Ads broad match modifier syntax.
Why are long-tail keywords important for SEO?
Long-tail keywords (phrases with 3+ words) make up roughly 70% of all search queries. They have lower competition, higher conversion rates, and clearer search intent than short head terms. Targeting long-tail keywords is one of the most effective ways to drive qualified organic traffic.
Can I use the generated keywords for Google Ads?
Yes. Keyword combinations are perfect for building tightly themed ad groups in Google Ads. Combine product terms with intent modifiers (buy, discount, review) and location terms to create comprehensive keyword lists for your PPC campaigns.
Is there a limit to how many keywords I can combine?
There is no hard limit, but keep in mind that the number of combinations grows multiplicatively. Three lists of 50 keywords each produce 125,000 combinations. For practical SEO use, start with focused lists of 10-20 keywords per column.
