Google, which holds an extremely dominant position in the search market, made some major modifications including changes to its search results page layout which rolled out last month. Now it’s promising “50 percent fresher results for web searches” than those found with its last indexing service. In a blog Google explains the need for Caffeine, writing, “Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.”
