Understand search demand, research competitors, explore advertising strategies and assess AI visibility with structured marketing data.
Start with a product or category keyword. Compare search volume, related terms, trends and search results to decide which topics to research for your next product page or content brief.
Start with a competing website. Explore its ranking pages, keyword gaps, traffic estimates and backlinks to find content opportunities and compare its search presence with yours.
Research a competitor’s paid-search keywords, ad copy and landing pages. Compare the messages and destinations they use to inform your own campaign briefs.
Research a brand or topic through AI answer samples, mentions and citations. See where brands appear and which websites are cited to guide further content research.
Connect the data you need to the tools you use in three steps.
Find the data your task needs. Review the API documentation for supported inputs, markets and returned fields.

Marketing Data APIs organize keyword research, search results, website and competitor intelligence, backlinks, advertising and AI visibility data. These general-purpose datasets help ecommerce teams research demand, understand competitors and inform marketing decisions.
No. SEO is one use case within Marketing Data. Keywords, search results, on-page data and backlinks support SEO research; paid-search keywords and ad samples support advertising research; AI answers, mentions and citations support AI visibility research. These datasets do not represent campaign attribution or private advertising account performance.
No. The datasets cover general web search, websites and marketing intelligence. Ecommerce teams can apply them to product, category, content and competitor research. Supported markets and website coverage depend on the individual dataset.
Product Data focuses on marketplace products, prices, reviews and sellers. Marketing Data covers web search, website intelligence, advertising and AI visibility. Google search volume is not Amazon search volume, and estimated website traffic is not product sales.
The catalog includes keyword search volume, CPC, keyword ideas and Google organic search results. Search volume and keyword difficulty depend on the source and market; a SERP snapshot is not a continuous rank-tracking service. These are not official Google APIs.
Public search and website research does not require access to your Google Search Console account. Your own clicks, impressions and index inspection require customer-provided data or authorized access. These three connections are listed separately from third-party data APIs.
Website Traffic API capabilities cover traffic estimates and available history, not your site's measured analytics. Backlinks API capabilities cover discovered links, referring domains, observed link changes and provider-specific domain or page metrics. Coverage, freshness and supported fields vary by dataset and source.
AI Visibility API capabilities cover answer samples, observed mentions, citations and available history. A GEO readiness score evaluates page evidence and structure; it does not prove that an AI system has mentioned or recommended your product. The source, sampling method and date must accompany observed results.
Review the source, observation date, geographic coverage, supported fields, request limits and billing terms for the dataset you need. These details determine whether the data fits your workflow.
Bring marketing data into your apps, workflows and AI agents.
