DataForSEO is an SEO and marketing data provider. SEO (search engine optimization) is the work of making web pages rank higher in search engines. DataForSEO started in 2011 as in-house software for an SEO agency and launched its first API in 2016; it describes itself as a data partner for more than 750 SEO software companies and agencies.
DataForSEO collects data from search engines, marketplaces, review platforms and other websites, and sells it through APIs and databases. The SERP API returns search engine results pages (SERPs) from Google, Bing, YouTube and other engines. The Keywords Data API gives search volumes, trends and advertising data for keywords. The Backlinks API reports which other sites link to a domain, and the On-Page API crawls and audits a website. Other APIs cover app stores, business listings, reviews, Amazon and Google Shopping, and LLM visibility (how brands appear in answers from large language models). Developers can also connect through an MCP server, Google Sheets, n8n or Zapier.
Pricing is usage-based, with no subscription: the customer adds funds to an account balance, and each API request is charged at its own rate.
