Keyword generator — ideas, volume & difficulty
Turn one seed keyword into hundreds of related terms with volume and difficulty.
Enter up to five seed keywords to expand them into related ideas, each with monthly search volume, keyword difficulty, search intent and CPC. Useful for filling out a content calendar, finding low-difficulty terms to target, and briefing writers with the exact phrases people search. One UnifAPI SEO lookup per check.
How do I find keyword ideas from a seed keyword?
Enter up to 5 seed keywords above. The generator returns 50 related keyword ideas, highest volume first, each with monthly search volume, keyword difficulty, search intent and CPC.
How do I find low-difficulty keywords?
Scan the difficulty column: under 30 is generally within reach for newer sites. Each idea also shows its intent, so you can match it to a blog post or a product page.
How much does a keyword ideas run cost?
Sample runs are free and labeled as samples. A live run costs 50 credits ($0.05) for 50 ideas, and the first top-up adds a one-time 2,000-credit bonus.

Questions about this tool
Where do the keyword ideas come from?
Each seed is expanded against the same keyword index Google Ads draws on, returning related terms with real monthly search volume, difficulty, intent and CPC — not autocomplete guesses.
How is this different from the search volume checker?
The volume checker scores keywords you already have. This generator discovers new ones: give it a seed and it returns related terms you might not have thought of, each with the same metrics so you can pick the best targets.
How many ideas can I get?
This free tool shows a capped page of the highest-volume ideas. A workspace can pull up to 1,000 ideas per call and page through the full set from an agent or script.
What does search intent mean?
Intent labels each keyword as informational, commercial, transactional or navigational — a quick way to match a term to the right page type, from a blog explainer to a product page.
