SiteData

Traffic checking, advertising research and SEO analysis share one Chrome extension in SiteData. Open any website and it shows traffic and its sources, domain rating, popular keywords with search volume, outbound domains, AdSense IDs and related sites. On Google search pages it adds current keyword search volume, CPC and Key Ratio (KGR), and shows recent advertising activity for each domain, alongside a Google Ads transparency view and a Facebook Ads database link. Quick actions copy the domain, search it on Bing or open an external backlink query. Favorite domains and keywords can be reached through a SiteData MCP and CLI, and no API key is required to use the extension. Screenshots can capture just the sidebar or the full current page, and results can be exported to CSV.
