DataForSEO

The broadest data ecosystem in the SERP API category. If you need SERP results plus keyword data, backlinks, and domain analytics, DataForSEO bundles it all at $0.60/1K (standard tier). Pricing in context: standard SERP API at $0.60/1K versus Serper.dev at $1/1K for Google-only, SerpAPI from $25/1K on its entry (Starter) tier dropping to ~$9.17/1K on its largest published (Big Data) plan (free tier 250 queries/month; most of Google's DMCA suit against it dismissed July 2026), ScraperAPI at ~$12/1K on its entry (Hobby) plan dropping toward ~$2.50/1K at volume, and ScrapingDog at $0.29/1K at volume. DataForSEO's price advantage compounds when you also need backlinks, keyword volume, or on-page data – those are separate APIs that would otherwise require Ahrefs/Semrush/Moz subscriptions. The API surface is sprawling: 50+ endpoints covering live SERP, historical SERP, keyword research, backlinks, on-page audits, and domain metrics. Documentation can be overwhelming for first-time users. Authentication uses HTTP Basic with login/password, not bearer tokens – worth knowing if your client library expects the latter. Best for: SEO platforms, agencies bundling reports, teams replacing multi-vendor stacks (SERP + keyword + backlink). Overkill if you only need plain Google SERP results – Serper.dev or ScrapingDog are simpler and cheaper for that single use case. Legal posture: DataForSEO operates from Estonia, runs its own infrastructure, and was not named in Google's December 2025 DMCA suit (which targeted SerpAPI). Lower vendor risk than US-based SERP scrapers facing Google's anti-circumvention push.
