A regional keyword research tool with historical trends, competitor analysis, and project workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Keyword Discovery is a web-based keyword research tool from Trillion Ltd for SEO, content, PPC, and broader keyword research workflows. It combines keyword search, related-term discovery, search-volume statistics, regional and specialty databases, competitor research, historical and seasonal trends, and keyword project management. Its free Standard plan makes it accessible for initial research, while the Professional plan adds broader project and competitor-analysis capabilities.
Pricing is structured around two main tiers. Standard is free and includes 1,500 searches per day, 1,000 displayed results, 20 projects, regional databases, and keyword management and permutation tools. Professional costs $49.95 per month and keeps the same daily search and displayed-result limits while adding unlimited projects, competitor and cross-reference tools, and Top 1,000 keyword lists. Professional annual costs $499.95 per year and includes the Professional plan features with a 12-month subscription. The pricing makes the free tier useful for exploration, while the paid tier is a more significant commitment for expanded workflows.
Keyword Discovery’s strongest fit is its regional and historical focus. Searchers can examine seasonal trends, compare competitor keywords, manage keyword sets, import and export data, and run keyword density analysis. The web and API platform options also support workflows that need XML API access. Its main constraint is breadth around newer SERP and intent analysis: the available positioning does not verify that coverage. Choose Keyword Discovery when regional databases, keyword history, and competitor research matter most. Consider an alternative when advanced SERP or search-intent validation is central to the workflow.
