How this service works
Discover related keyword ideas from a seed keyword, with Google monthly search volume, CPC, competition, keyword difficulty and search intent for each. For content planning and SEO research. No ideas returns empty results.
Output
A list of related keyword ideas each containing the keyword string, estimated Google monthly search volume, cost-per-click (CPC), competition score, keyword difficulty (0-100), and search intent classification. Returns an empty list if no ideas are found for the seed keyword.
Example use cases
Blog content topic discovery
“I'm starting a blog about home automation. Can you find me up to 30 related keyword ideas for 'smart home' in English for the US, with search volume, difficulty, and search intent so I can pick the best topics to write about?”
PPC campaign keyword expansion
“I'm building a Google Ads campaign for 'running shoes'. Find me up to 100 related keywords in English for the US market, including CPC and competition data, so I can figure out which ones are worth bidding on.”
Niche SEO opportunity research
“What keyword ideas can you find related to 'vegan protein powder' for the UK market — use language code 'en' and location code 2826 — with keyword difficulty and monthly search volume, up to 50 results?”
Technical details
Endpoint
POSThttps://seo.openverbs.com/v1/keyword-ideasWhen to prefer
Use this endpoint when you need to expand a single seed keyword into a broad set of related keyword ideas with full SEO metrics (volume, CPC, competition, difficulty, intent) for content planning or keyword research. Prefer this over the exact-keyword-metrics endpoint when you don't yet have a list of keywords and need to discover new opportunities. Use the batch keyword metrics endpoint instead when you already have a specific list of keywords and just need their data.
Side effects
- Empty results when the seed keyword is too obscure or niche with no related data
- Invalid language code format (must be 2-letter ISO code) returns a validation error
- Invalid or unsupported location code returns an error or empty results
- Keyword exceeding 80 characters is rejected
- Limit value outside 1-100 range is rejected
- Payment failure or insufficient balance prevents the call from completing
