Involved in the Google Caffeine release is web indexing that offers new content faster



Wednesday Google’s new web indexing system known as Caffeine went live. Announcing the global launch of Caffeine, Google said its search engine technology makes a lot more freshly minted web content accessible and delivers that new content much faster than before. Searchers and web content developers don't have to change the way they use Google. But links to a wider range of relevant content are now presented much faster following the content has actually been published. The Caffeine overhaul of the web indexing technology also provides Google much a lot more flexibility to keep pace with a web that is evolving at an ever increasing rate.

Google Caffeine launch - speed isn't really every little thing



Google said the Caffeine launch delivers 50 percent fresher search results. It may be hard to translate into an advantage for average Google Users. PCWorld tested a comparison of web indexing systems when Caffeine was in development and found that results took .15 seconds on the regular Google search and .09 seconds on Caffeine. Since Caffeine is the regular Google search now, the test can’t be repeated. And .06 seconds probably won't make much of a difference for searchers, no matter how tight the deadline. Nevertheless, what shows up .06 seconds faster will make a difference for content publishing.



Real time content publishing


Fresh content and more of it are the immediate benefits for the average user of Google Caffeine. Google's Matt Cutts told Search Engine Land that that "Caffeine benefits both searchers and content owners because it means that all content (and not just content deemed “real time”) can be searchable within seconds after it's crawled.” As outlined by Search Engine Land, the old Google would crawl a set of pages, process those pages and add them to the index. Rather than one page at a time proceeding, the whole batch had to go at the very same time. Now pages are processed individually.



Caffeine has astronomical storage capacity



For Caffeine to eliminate the delay between when it finds a page and makes it available to the public demands an astronomical amount of storage. Carrie Grimes said Caffeine indexed web pages on an enormous scale. Each and every second Google processes hundreds of thousands of pages. Anything paper processed that fast would stack 3 miles high every second. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds a whole lot of new info at a rate of hundreds of thousands of gigabytes per day. You would have to have 625,000 of the largest iPods to store that much info; if these were stacked end-to-end they would go for more than 40 miles. The bill from Apple would be $155,625,000.



Keeping up with Caffeine

The Google Caffeine launch doesn't change any of the web searching or content publishing. But Resource Shelf points out an significant detail. Information found one day may not be there if you go back to the very same location the next. The Cache and the page is refreshed a lot more often. If a searcher needs material on a page the way it looked at noon on Wednesday, it’s a good idea to make a duplicate with something like Zotero, a Firefox extension because later that night the content on the page might change when the cache is updated.
