What are Ahrefs 3 main data sources:

Ahrefs primarily gathers its vast dataset from three main sources. Their proprietary crawler constantly indexes the web, similar to search engine crawlers, to discover new pages, backlinks, and content. This forms the foundation of their backlink and organic search data. They integrate data from Google Keyword Planner to provide keyword ideas, search volumes, and competition metrics, leveraging Google's own insights into search demand. Finally, SERP data providers supply information on search engine results pages, allowing Ahrefs to analyze ranking positions, featured snippets, and other SERP features for various keywords. Incorrect options: "Parser" is a component of a crawler, not a distinct data source. "Google Search Console" provides data specific to a user's own website, not the broad market data Ahrefs offers.
