Google is Creating a Mobile-only Search Index
Ask any Webmaster or SEO specialist what have been the most significant advancements in search over the past few years and they are highly likely to count mobile at the top of their list. Now it appears Google is willing to take its focus on optimising services for mobile users to the next level with a search index devoted entirely to mobile results - and make it their primary search index.
According to information published by Search Engine Land, Google is going to create a new mobile search index “within months”. This will help to give mobile users access to more relevant and higher-quality content. It is currently unclear how exactly the new mobile index will work; whether it will only contain results considered “mobile-friendly”, and, as a primary index, whether it will really not be used for desktop queries.
The new index is undoubtedly the culmination of Google’s attempts to push webmasters to prioritise the creation of mobile-friendly sites; already they favour those who do so in their current SERPs, a result of so-called #Mobilegeddon back in April 2015. A mobile-only index would empower the search engine to expand on the quality of their current algorithm, with which it is all-too common for alternate mobile sites of desktop sites to not live up to the expectations created in SERPs.
In relation to how it will affect ranking Barry Schwartz of RustyBrick had this to say:
“The most substantial change will likely be that by having a mobile index, Google can run its ranking algorithm in a different fashion across “pure” mobile content rather than the current system that extracts data from desktop content to determine mobile rankings.”
While a desktop index will continue to be maintained, it will eventually take back seat to the mobile index, becoming less regularly updated. In a statement to the Guardian Google commented “[we] are always experimenting with different approaches to keep search index as relevant and useful as possible, but we don’t have any new developments to announce.”
