DataForSEO

Developers and SEO software makers use DataForSEO as a source of raw search data delivered through an API. The company supplies SERP, keyword, backlink and ecommerce data to SEO software companies and agencies. Its product line includes a SERP API, Keywords Data APIs built on Google Ads and Google Trends, and a backlinks dataset, along with downloadable databases. A newer LLM Mentions API gives data for tracking and improving brand visibility in AI answers, and the company runs its own AI Visibility Tracker. Development guides show how to build keyword research tools, rank trackers, backlink analysis tools and local SEO tools on top of the APIs. Pricing follows a pay-per-use model, and support is offered around the clock. A set of free tools, such as lists of the top keywords and websites and a SERP volatility index, is open to anyone, and a free trial is offered to new API users.
