Today Google announced that Caffeine has become it's new search index. Caffeine will provide Google searchers with 50% fresher results and will consist of the largest index of websites that Google has ever provided.

What really sets Caffeine apart is the way it indexes the web. The previous index fetched new content in layers. This would create a significant delay in how fast Google could bring new content. With Caffeine smaller "packets" of the index are constantly being updated to bring you fresher content.

This faster, fresher index by Google will no doubt change how the web is presented, but it will also change the thought of publishing content. Caffeine's ability to better crawl and index the web will increase the emphasis of importance of content you present on your website. Caffeine reinforces the basic theory of SEO, "Content is King" and now Google can find it even faster.
