Google is making a huge change to their search engine that could have huge implications for the future of search.
Until now, Google has maintained a single search index, which cataloged the entire web for Google’s algorithm to sort through. However, that will be changing soon as Google’s Gary Illyes announced the search engine would be releasing a separate mobile search index.
The new mobile index will become Google’s “primary” index that it uses to deliver the majority of search results. At the same time, the company will continue to maintain a separate desktop search index which will be slightly less up-to-date.
The announcement came last week during a keynote address at Pubcon from Gary Illyes, webmaster trend analyst with Google. While Illyes later confirmed to Search Engine Land the rollout of the new index would be coming within “months,” he was otherwise short on details of how the mobile index will work.
It is also unclear in which circumstances Google will use which search index or just how behind the desktop index is. What is clear is that Google sees mobile as the future of search despite still seeing significant desktop usage.
Most likely, the new index means Google will be switching from a system which selectively pulls information from the single index for mobile results to a new system which uses the separate index for queries coming from mobile devices.
More information is likely to come in the near future, but for now, all we know is Google is gearing up for big changes to further prioritize mobile searchers.
