Yes, in two ways. Crawl access is a hard prerequisite: Brave’s documentation says its crawler won’t index a page that Googlebot can’t crawl, which puts Google access upstream of Claude’s web-search visibility. Rank matters more loosely: 64% of Claude’s citations appear in Google’s top 50 (34% in the top 10), correlated but not determining. Access is table stakes. Rank helps at the margin.
