DataForSEO

An EU SEO Data API — Built for Developers

DataForSEO is a developer-first data API, not an end-user SEO app. Instead of logging into a dashboard, you call its API stack to pull SERP results, backlink and keyword data, on-page audits, and business-listing data, then build your own tools on top.

What DataForSEO Provides

• SERP API across search engines, with location and language targeting
• Backlinks & keyword data for research and competitive analysis
• On-page & content audit endpoints
• Pay-as-you-go pricing: prepaid balance that never expires, plus a free sandbox and $1 starter credit

Compliance Notes

The legal entity — DataForSEO OÜ — is registered in Estonia (EU), which is why it belongs on a European directory. It is ISO 27001 certified, publishes a Data Processing Agreement, and references GDPR Articles 28 and 32.

The caveat: DataForSEO runs on Google and Microsoft Azure (US cloud providers) and does not state an EU-only data-residency region, and its team is largely based in Ukraine. So while its GDPR posture is strong, EU data residency is not verified — which is why we list it as partially compliant rather than fully EU-hosted. For SEO tooling where EU hosting is confirmed, compare the European SEO software list.
