What happened
Caffeine was a rebuild of Google’s indexing system rather than a ranking change. Instead of refreshing the index in large batches, Google could add and update pages continuously, so new content appeared in search much faster. Google said it delivered about 50% fresher results.

What it means for marketers today
Fast indexing is why news, updates and fresh content can rank within hours today. Keep sitemaps clean and link to new pages from existing ones so Google discovers them quickly.
