In July, Google announced that it would start telling mobile users when pages in their search results may not work. For example, if a page uses flash, Google would tell users that it may not work on their device.
“A common annoyance for web users is when websites require browser technologies that are not supported by their device,” wrote Google’s Keita Oda and Pierre Far at the time. “When users access such pages, they may see nothing but a blank space or miss out a large portion of the page’s contents.”
Google first launched the notifications to English-language searchers in the U.S. Far announced Tuesday morning that snippets indicating Flash-heavy pages on mobile SERPs have now started rolling out globally. In a Google+ update, he wrote:
Starting today, we'll start showing a localized version of this snippet for Spanish searches on google.es, Japanese queries on google.co.jp, and English queries on google.co.uk.
Google actually offers some resources to help you out with this stuff. Web Fundamentals will show you some modern best practices, and the Web Starter Kit is a starter framework supporting Web Fundamentals.
