Strong internal linking would come first, making sure important pages are easy for crawlers to reach quickly. Clean XML sitemaps help guide search engines directly to priority content. I'd focus on canonical tags to avoid wasting crawl on duplicates, plus robots.txt rules to block low-value pages. Optimized page speed matters since faster pages get crawled more efficiently. Updating structured data on key pages helps search engines understand content faster. Monitoring server logs shows how bots move and where they stop, similar to tracking user flow.
