How this service works
Keywords two domains BOTH rank for, with each position — the competitive overlap
Output
A list of keywords that both submitted domains rank for in Google organic search results, with each domain's current ranking position for every shared keyword, up to the specified limit (default 20, max 100).
Example use cases
Competitor overlap discovery for SEO strategy
“Find the keywords that both moz.com and ahrefs.com rank for on Google in the United States — give me up to 30 results so I can see where they're head-to-head.”
German market keyword battleground analysis
“Which keywords do both otto.de and zalando.de rank for in Germany on Google? Show me their positions for each shared keyword, up to 50 results.”
New entrant benchmarking against market leader
“I just launched mybrand.com and want to know which keywords we already share with bigcompetitor.com — pull up to 20 overlapping keywords with both our positions so I know where to focus.”
Technical details
Endpoint
POSThttps://agent.connskill.com/v1/keyword-gap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify the specific intersection of two domains' Google organic rankings — i.e. the keywords where both sites are actively competing. It is ideal for competitive analysis, content gap research, and benchmarking a new site against an established competitor. Prefer this over a general keyword suggestions endpoint when you already know both domains and want to find shared ground rather than discover new keywords.
Side effects
- Invalid or unreachable domain names return empty or error response
- Domains with no shared keywords return an empty keyword list
- Unsupported location_code or language_code values may cause errors or empty results
- Limit exceeding 100 is capped or rejected
- Payment not included or insufficient USDC causes 402 payment required error
