A member of Google’s Search Quality group, Matt Cutts blogged that Google will release its Caffeine search engine index after the holidays. This new index is being developed to improve Google’s indexing infrastructure and give users better results. Because this is a busy time for Webmasters, Google is releasing this after the holidays. Until then, this technology will go live at one data center, which will affect a limited number of users. This prerelease will help Google continually collect data and improve the technology. This is just another reason why having a continuous and well-rounded SEO program is so important.
