Find keyword opportunities for a domain
Step 1. Analyze a domain’s global performance
Start by getting a high-level view of your target domain’s performance. The Get worldwide domain overview endpoint aggregates organic and paid search statistics on a global scale.
curl --location 'https://api.seranking.com/v1/domain/overview/worldwide?domain=visa.com¤cy=USD' \
--header 'Authorization: Token YOUR_API_KEY'
What you’ll get:
- Total number of keywords
- Estimated organic and paid traffic
- Traffic value across regions
Step 2. Identify top competitors
Next, find out who you’re competing with in the SERPs. The Get domain competitors endpoint returns the top organic or paid competitors for your domain.
Example: Find the top organic competitors for visa.com in the US database
curl --location 'https://api.seranking.com/v1/domain/competitors?domain=visa.com&type=organic&source=us' \
--header 'Authorization: Token YOUR_API_KEY'
What you’ll get:
- A list of domains, such as mastercard.com or paypal.com
- The number of overlapping keywords with each domain
Step 3. Find new keyword opportunities
After identifying your competitors, you can find new keyword opportunities in several ways.
A. Analyze your dropped keywords (low-hanging fruit)
Use the Get domain keyword rankings endpoint with the pos_change=lost parameter to find keywords your domain no longer ranks for. These are often quick wins for content updates or re-optimization.
Example: Retrieve keywords that visa.com has lost in the US
curl --location 'https://api.seranking.com/v1/domain/keywords?source=us&domain=visa.com&type=organic&pos_change=lost&order_field=volume&order_type=desc' \
--header 'Authorization: Token YOUR_API_KEY'
B. Find competitor keyword gaps
Use the Analyze keyword overlap and gaps endpoint with diff=1 to find keywords a competitor ranks for, but you don’t.
Example: Find keywords that mastercard.com ranks for in the US, but visa.com doesn’t
curl --location 'https://api.seranking.com/v1/domain/keywords/comparison?source=us&domain=mastercard.com&compare=visa.com&type=organic&diff=1&order_type=desc&order_field=volume&cols=keyword%2Cvolume%2Ccpc%2Ccompetition%2Cdifficulty%2Cposition%2Cprice%2Ctraffic' \
--header 'Authorization: Token YOUR_API_KEY'
C. Expand your topic clusters
Use the Get similar keywords and Get related keywords endpoints to build topic clusters with close variants or semantically related queries.
Example: Find semantically similar keywords to best credit cards
curl --location 'https://api.seranking.com/v1/keywords/similar?source=us&keyword=best%20credit%20cards&limit=10' \
--header 'Authorization: Token YOUR_API_KEY'
D. Optimize for AI Overviews
Use the Get prompts by target endpoint to see where competitors appear in AI Overview (AIO) snippets, and your domain doesn’t.
Example: Retrieve prompts where mastercard.com appears in an AI Overview snippet
curl --location 'https://api.seranking.com/v1/ai-search/prompts-by-target?target=mastercard.com&scope=domain&source=us&engine=ai-overview&limit=10' \
--header 'Authorization: Token YOUR_API_KEY'
Next steps:
- For each prompt in the response, check the
linksarray. - If your domain is absent, this indicates a content gap you can target.
