A commercial keyword database built on Google search data, the same class of source the paid SEO suites use. Search volume is an average of monthly searches, difficulty is a 0-100 estimate of how hard the top of page one is to break into, and CPC is what advertisers currently pay for a click. ### What counts as a good difficulty score? Under 15 is easy and realistic for a new site. 15-29 is medium and usually winnable with a genuinely good article. 30-49 is hard and needs established authority. Above 50, expect to need serious backlinks. Look for keywords with meaningful volume and a low score — that is where the opportunity hides. ### Why does search intent matter? Because it determines what to write. Informational intent wants a guide, commercial intent wants a comparison, transactional intent wants a product page. Matching the format to the intent is often the difference between ranking and not, regardless of how well written the page is. ### Which countries are supported? Eight to start: the United States, United Kingdom, Canada, Australia, India, Germany, France and Spain. Volumes differ substantially by market, so pick the one you actually sell into rather than defaulting to the US. ### Is there a usage limit? Yes — this is the one tool here that costs us money per lookup, so there is a fair-use limit per visitor and a daily ceiling overall. Results are cached for 30 days, so repeating a search is instant and free. If you hit the limit, come back tomorrow. ### Why is search volume zero for some keywords? Either genuinely nobody searches it, or the volume is too low to report reliably. Zero-volume keywords are not always worthless — a very specific phrase can still convert well — but they should not be the foundation of a content plan. ## Related tools - [Keyword Density Checker](https://skribra.com/tools/keyword-density-checker): Check how often your keywords appear in a piece of content. - [Technical SEO Audit](https://skribra.com/tools/technical-seo-audit): Run 30 on-page SEO checks against any domain in about a second. - [SERP Preview](https://skribra.com/tools/serp-preview): See how your title and description will appear in Google results. - [Headline Analyzer](https://skribra.com/tools/headline-analyzer): Score your headlines for length, structure and clickability. ## Machine-readable index - HTML version of this page: https://skribra.com/tools/keyword-research - Site index for agents: https://skribra.com/llms.txt - Sitemap: https://skribra.com/sitemap.xml - Public REST API: https://skribra.com/api/v1 - OpenAPI specification: https://skribra.com/openapi.json
