Caffeine
New indexing infrastructure delivering results about 50 percent fresher and near-continuous crawling of the web.
Key points
- A new indexing infrastructure replacing the old batch-update system.
- Results roughly 50 percent fresher according to Google.
- Near-continuous crawling and indexing of the web, without waiting for a global refresh.
- Freshness and publishing frequency become concrete advantages.
Analysis
Caffeine does not change ranking as such, but the way Google crawls and stores the web. By moving from wave-based indexing to continuous processing, Google can incorporate new content in near real time. This infrastructure laid the technical foundations for many later developments, including the consideration of freshness.
For publishers, this means that published or updated content can be taken into account much faster than before. Sites that publish regularly and cover the news of their sector gain a responsiveness advantage. This freshness challenge remains central to visibility, including in AI answers that often favor recent sources.
What to do
- Maintain a steady publishing pace and update strategic content to signal its currency.
- Use the URL inspection tool to check that new pages are crawled and indexed quickly.
- Optimize crawl budget (internal linking, sitemap, server response time) to facilitate continuous indexing.
Much faster indexing of new content. Freshness and publishing frequency become assets.
