Google’s mobile-first search indexing has rolled out to more sites, the search giant announced the process on Monday. After a year and a half of testing and experimentation, the rollout will be implemented very slowly to some sites.
The sites that follow the best practices for mobile-first indexing will receive the rollout, according to Google. This is the first time Google is moving various sites to this mobile-first indexing process which uses the pages’ phone-optimized versions for indexing and ranking.
Back in 2016, Google revealed its plans to modify the search index operating which included shifting of its algorithms for using the mobile version of a website’s content to index its pages. Then after in December 2017, Google detailed it had started to move some sites to mobile-first indexing but did not mention which properties had been made the change.
Google noted that this new fashion of indexing will likely help the site “perform better” in mobile search results and directly won’t affect how content is ranked.
According to Google, there will be only one index for search results that means a mobile-first index will be separated from its main index.
Google also said “site owners will see significantly increased crawl rate from the Smartphone Googlebot. Additionally, Google will show the mobile version of pages in Search results and Google cached pages.”
“If you only have desktop content, you will continue to be represented in our index,” Google announced.
Google has not revealed details about when the rollout of the mobile-first indexing would complete.
