Keyword Discovery

Overview

Keyword Discovery is a keyword research service for SEO and PPC marketers, niche marketers, and people researching domains. It is best suited to users who value broad search data, competitor terms, and project-based keyword workflows; it is a weaker fit when search intent or SERP analysis is essential.

Key features

The toolkit combines search-volume and keyword-difficulty data with historical trends, competitor research, PPC bid values, keyword density analysis, domain research, and Keyword Effectiveness Indicator (KEI) analysis. That range can support both organic planning and paid campaigns, though the absence of search-intent data and SERP analysis leaves gaps for teams that need to understand why users search or inspect ranking pages. The maker says its database contains nearly 38 billion searches from more than 200 search engines worldwide. Data is collected daily, and the online database is updated monthly.

Country-specific databases cover Australia, Canada, the Netherlands, France, Germany, Italy, Norway, Poland, Portugal, Spain, Sweden, the UK, and the US. This is useful for campaigns targeting those markets, but the stated coverage does not extend to every region. Keyword results can be saved in projects and copied, renamed, translated, or exported. Imports accept Excel and text files, meta tags, and URLs, while research data can be exported. The workflow supports organizing keyword lists across campaigns, with project and daily usage caps shaping how much work fits on the free plan.

The XML API can supply keyword suggestions to a website or support a custom keyword research tool. That makes the service more compelling for developers and larger operations than for a solo marketer who only needs a web interface. Support includes an FAQ, forum, quick-start guide, user manual, video tutorials, and live chat during business hours.

Pricing

The free Standard plan costs nothing. It allows 1,500 searches/day, up to 1,000 results, three domain research results, 1,000 analyze/KEI credits/day, 20 projects, and 10,000 terms/project. Those core search and analysis allowances are substantial for trying routine keyword work, but the three-result domain research cap and fixed project limit make it less suitable for broader competitor or multi-campaign workflows.

Professional costs $49.95 a month. It retains 1,500 searches/day, 1,000 results, 1,000 analyze/KEI credits/day, and 10,000 terms/project, while raising domain research to 100 results and removing the project limit. This is the better fit for ongoing work that needs deeper domain research or many separate projects; it does not raise the daily search or analysis quotas.

Enterprise XML API Access costs $495 a month and includes Professional features, up to 10,000 results through the XML API, and 10,000 API credits/month. It is aimed at integrations and custom tools rather than users who only need browser-based keyword research. The free trial is limited to 10 results per query, compared with up to 1,000 through the website interface on paid subscriptions. Subscriptions renew automatically and can be cancelled at any time at least one day before the current subscription expires.

Platforms

Keyword Discovery is available on the web and through an API. The API extends keyword suggestions into other sites or tools, while the web interface serves users doing research directly.

Who it's for

Choose Keyword Discovery for keyword research spanning SEO, PPC, niche marketing, and domain parking, particularly when competitor research, regional databases, and project exports matter. It is less appropriate if search intent or SERP analysis is a core requirement, or if your target market falls outside the country databases listed above.

Pros and cons

• Pro: The free plan keeps daily searches and analyze/KEI credits at 1,000 or more, with up to 1,000 results per search, making it practical for sustained basic research.
• Pro: Historical trends, PPC values, competitor research, domain tools, and KEI analysis cover several distinct keyword-planning needs in one service.
• Pro: Projects support copying, renaming, translation, and exports, and imports accept files, meta tags, and URLs.
• Con: Search-intent data and SERP analysis are absent, limiting its usefulness for workflows centered on intent classification or page-level ranking analysis.
• Con: The free plan allows only three domain research results and 20 projects, while the trial view is capped at 10 results per query.
• Con: Professional increases domain research and project capacity but keeps the same daily search and analyze/KEI quotas as Standard.

Verdict

Keyword Discovery is a strong choice for marketers who want extensive keyword research, competitor discovery, regional databases, and project organization, with a free plan that preserves meaningful search capacity. Its main reason to choose is the breadth of tools and data workflows; look elsewhere if you need search intent or SERP analysis, or if the daily caps and regional coverage do not suit your campaigns.
