How to find competitors for a domain using SemRush?▼

Query the domain_organic_organic endpoint with your domain to get domains competing for the same organic keywords. Results include competition level, common keywords, and each competitor's organic traffic metrics.

What API key do I need for SemRush data?▼

You need a SemRush API key from semrush.com/api, set as SEMRUSH_API_KEY in a .env file or environment. The key is passed as the key parameter on every request to api.semrush.com.

Why does the SemRush API return ERROR 50 NOTHING FOUND?▼

ERROR 50 means no data exists for that query. Try a different regional database such as uk instead of us, use the root domain instead of a subdomain, or broaden the keyword phrase.

What format does the SemRush API return?▼

Responses are semicolon-delimited CSV text with the first line as the header row. Parse results with tools like awk using semicolon as the field separator, selecting columns via the export_columns parameter.
