Keyword Tool vs Rank Math SEO

Keyword Tool generates long-tail keyword suggestions from autocomplete when given a seed term. It supports keyword and competitor research across 16 platforms, including Google, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest and Google Trends. The free tool works without an account and can return 750+ Google autocomplete keywords. Paid plans add search volume, cost per click, competition scores, device breakdown and historical trends; they also support search-volume enrichment for up to 1,000 keywords per request, with daily capacity depending on the plan. Access includes the web interface, API and MCP, and Claude, Cursor and ChatGPT are named as compatible assistants. Google coverage includes 190+ countries, 68,000+ locations and 50+ languages. The site says Google and Bing metrics come from planner ecosystems, while volumes for other platforms are modeled estimates based on clickstream signals. Web, API and MCP share a daily request pool, and available MCP tools can vary by endpoint, plan and rollout status. Paid plans start at $68 a month. There is no free trial; the pricing FAQ lists a 30-day money-back guarantee for paid plans.
