Google's docs usage in the US reaches 20%, which will support search engine crawling-seo news

According to a recent IDC survey, 1/5 of American companies use Google Docs, and about 5% of companies use it two years ago. Although Google's docs usage is rising, more than 97% of companies in the past year and a half still use Microsoft's office, which many companies use at the same time.
Google Docs has never been crawled by other search engines, and this situation will change within two weeks. Google intends to allow shared documents to be crawled by search engines, users only need to use the "share" option "to publish the document as a webpage" to capture the document by other search engines and stop publishing.
What will this bring to Seo? Some people say it is PR's nightmare, but it is still unknown.
