Google announced they are rolling out a new search algorithm change that helps make the search results “fresher.” The big news here is that besides for the results being fresher, the results will change for about 35% of all searches.
Caffeine Was Infrastructure, This Is Algorithmic
Fresher results can make for more relevant results, which is why Google moved over to the caffeine infrastructure last year. That was only an infrastructure change, to make sure Google can index, crawl and return results faster. Now Google changed their search algorithm to show fresher results, fresher than ever before.
