Competitor Domains Finder (SEO) finds the websites that compete with a domain in Google organic search. For each competitor you get the number of shared keywords, its average position on those keywords, and the size of its whole organic presence: estimated traffic, number of ranking keywords, and top-1, top-3 and top-10 counts (DataForSEO Labs data). Use it to map a market, find content and link opportunities, benchmark clients, or give AI agents competitive context. You pay $0.045 per domain plus $1 per 1,000 competitors delivered.

## Price per delivered record

| Competitor domain (`competitor-domain`) | $0.001 | $1 / 1,000 | Charged once per competitor record delivered. |
