Advertising Intelligence

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.

AI Visibility

Marketing Data API Questions.

What Are Marketing Data APIs?

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.

Are Marketing Data APIs Only For SEO?

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.

Are These APIs Limited To Ecommerce Websites?

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.

How Is Marketing Data Different From Product Data?

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.

Does This Include A Keyword Research API And Google SERP API?

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.

Do I Need To Connect Google Search Console?

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 connections are not included in this public Marketing Data API catalog.

What Would A Website Traffic API And Backlinks API Return?

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.

How Would An AI Visibility API Differ From A GEO Score?

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.

What Should I Check Before Integrating A Dataset?

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.
