Ultimate beginners guide to real time search by Kelvin Newman, SiteVisibility (May 26)
Google does real-time search in ways which we searchers might not fully appreciate. This article provides background on several initiatives.
+ Google Caffeine - faster spidering of blog content
+ PubSubHubBub - website pushes updates into the feeds rather than waiting for Google to scan
+ Query deserves freshness (QDF) - part of the ranking algorithm that will give priority to newness on topical questions as discerned from news coverage, blog coverage, and search volume. This has been in use since at least 2007.
Of course real-time is in search results now - most quickly viewed from Updates. It's more than Twitter - social media, Google News, Google Blog search.
