Mediapartners-Google is the crawler used by Google AdSense to analyze web pages and determine which ads to display. When a page includes AdSense ad code, this bot visits to understand the content and context, enabling better ad targeting and relevance. The crawler operates separately from standard Googlebot and focuses solely on pages with AdSense implementation. It analyzes page content, keywords, and context to match appropriate advertisements. Website owners using AdSense should ensure Mediapartners-Google can access their content for optimal ad performance and revenue.
