Analysis

Googlebot and Bingbot are the backbone of web search indexing. Googlebot powers Google Search (92% global market share) and renders JavaScript natively. Bingbot powers Bing Search and, critically, Microsoft Copilot's AI-generated answers.

Blocking either directly removes your content from that search engine. Googlebot is generally the priority for most sites, but Bingbot's role in powering Copilot makes it increasingly important for AI visibility. Both render JavaScript, respect robots.txt, and publish verified IP ranges.

When to manage Googlebot

Never block Googlebot unless you intentionally want to de-index from Google Search. Use Switch to monitor crawl patterns and serve optimized content.
