Free Keyword Ideas Generator

Every good content plan starts with the words your customers actually type. Enter a seed keyword and this generator returns related keyword ideas and question-style keywords people search for, each with a search volume range and a difficulty label.

Pick the ideas that match what you sell, then check the real Keyword Difficulty score for any of them in one click before you commit to writing.

How to use the keyword generator

Start broad. A two- or three-word seed like "protein calculator" or "feature request tool" surfaces more useful variations than a single generic word. Choose the country you want to rank in, because volumes and competition differ a lot between markets.

Results are split into two tabs. Ideas are phrase variations and related terms around your seed. Questions are the who/what/how/why searches, which make excellent H2s, FAQ entries and standalone articles.

  • Sort mentally by intent first: can you genuinely answer this search with your product or content?
  • Prefer ideas with a clear, specific intent over the highest-volume ones.
  • Click "Check KD" on shortlisted keywords to get the numeric difficulty score.

Reading search volume and difficulty labels

Volumes are shown as ranges rather than exact numbers, which is closer to how they should be treated anyway: search volume is an estimate that swings with seasonality. Use it to compare ideas against each other, not as a traffic forecast.

The difficulty label is a quick signal of how competitive page one is. For anything you plan to invest in, run the full Keyword Difficulty check, which also estimates how many referring domains you would need to compete.

Turning ideas into a content plan

Group related ideas that a single page could answer, pick the strongest one as the page's primary keyword, and use the rest as supporting sections. Question keywords often belong inside a broader page as an FAQ rather than on their own.

Frequently asked questions

Is this keyword generator really free?

Yes. You can run searches without an account. Creating a free ProductKit project lets you keep your research alongside your feedback board and roadmap.

Why are search volumes shown as ranges?

Search volume is modelled from sampled data and changes month to month. Ranges avoid false precision and are enough to compare keywords against each other.

How do I find long-tail keywords?

Use a more specific seed (three or more words) and look at the Questions tab. Long-tail keywords usually have lower volume but clearer intent and easier competition.
