What is seodata.dev?
seodata.dev provides keyword research data through an API and a remote MCP server, aimed at AI agents and the people who run them. A lookup returns monthly search volume, cost per click, competition, and related keywords for a selected country. It works with clients that can make HTTP requests or use MCP, as well as custom scripts. People can start without an account, register for a free key, or pay for unlimited lookups.
seodata.dev Features:
Keyword Metrics: Each lookup returns monthly search volume, CPC in USD, competition scored from 0 to 1, and the country used for the data.
Related Keywords: A lookup includes similar keywords with their own search volumes, so users can compare related ways people search for a topic.
Country Coverage: Keyword data is available for more than 50 countries, including the United States, United Kingdom, Germany, India, Japan, and Australia.
Bulk Lookups: The lookup_keywords MCP tool accepts up to 25 keywords in one call, with one country selected for each call.
Agent Access: Agents and scripts can connect through HTTP or MCP, and plain-text setup documentation supports agent-led registration and configuration.
Usage Options: Anonymous users get 20 lookups a day, free accounts get 500 a month, and the $4.99 monthly plan removes lookup caps.
seodata.dev Benefits:
Grounded Content Choices: Using measured search demand to choose topics can help content teams spend less effort on ideas that attract little search interest.
More Useful Comparisons: Seeing related terms alongside their volumes can make it easier to spot wording that better matches how people search.
Informed Ad Decisions: Comparing CPC with competition helps marketers assess the trade-offs behind a keyword before deciding how to approach paid search.
Lower Setup Friction: Starting without an account or payment card lets teams test keyword research in an existing agent workflow before committing.
Flexible Spending: Cached data and a low-cost unlimited option can help frequent users avoid paying repeatedly for lookups already made.
Use Cases:
SEO Topic Selection: An SEO writer can compare a broad topic with question-based related terms before choosing which article to plan.
Page Title Research: A content team can check alternative product or service phrases to decide which wording to use in a page title.
Ad Keyword Review: A marketer can compare CPC and competition across candidate terms when assessing keywords for a search advertising budget.
Market Demand Checks: A founder can look up terms describing a product idea and related searches to examine how people express that need.
