Free Keyword Research Tool
Enter any seed keyword and get real keyword ideas with live monthly search volume, CPC and difficulty — powered by Writelio’s search data. Free preview: 3 lookups per day.
Why keyword research comes first
Keyword research is the foundation of every piece of content that ranks. It tells you what your audience actually searches for, how much demand exists (search volume), how hard it is to rank (difficulty), and the commercial value (CPC). Skip it and you are guessing.
This free tool gives you a real sample of that data: enter a seed keyword and see 25 related ideas with live metrics, so you can spot opportunities worth writing about.
How to read the metrics
- Volume — average monthly searches. Higher means more potential traffic, but usually more competition.
- CPC — what advertisers pay per click; a proxy for commercial intent and value.
- KD (difficulty) — how hard it is to rank, 0–100. Newer sites should target lower-KD terms first.
- The sweet spot — decent volume, lower difficulty, and intent that matches what you offer.
Frequently asked questions
Is the search volume data real?
Yes — it comes from live search data, not estimates made up by the tool. The free version shows a sample of 25 ideas per seed keyword.
Why is there a daily limit?
Live keyword data costs money per lookup, so the free tool allows 3 lookups per day to keep it free and fast for everyone. For unlimited research, start a Writelio trial.
How do I pick the right keywords?
Look for terms with meaningful volume, manageable difficulty, and intent that matches your content. A cluster of related lower-difficulty keywords often beats chasing one hard head term.
Can I get the full keyword data?
Yes — Writelio includes full keyword research, clustering and a complete article pipeline. Start a 3-day free trial to unlock it.
