Google Notice For Flash Websites
Google always wants to promote modern website for modern device in SERP. And it can be very annoying for web users when websites require browser technologies that are not supported by their device.
When users come across such pages, they may see nothing but a blank space or miss out a large portion of the page’s contents which can be bad user experience.
Hence from now onwards Google will indicate to searchers when the algorithms detect pages that may not work on their devices. Right now, these notifications are seen in English search results in the US only. Such errors will be shown when the website using flash is not compatible to a user device.
Since, Adobe Flash is not supported on iOS devices or on Android versions 4.1 and higher, and a page whose contents are mostly Flash may be noted like this:
Developing Modern Websites For Multiple Device
Fortunately, making websites that work on all modern devices is not that hard: websites can make use HTML5 as it is universally supported, sometimes exclusively, by all devices. To help webmasters build websites that work on all types of devices regardless of the type of content they wish to serve, we recently announced two resources:
Web Fundamentals: A curated source for modern best practices. Web Fundamentals is a comprehensive resource for multi-device web development.
Web Starter Kit: a starter framework supporting the Web Fundamentals best practices out of the box. Start your project with the Web Starter Kit and ensure you’re following the Web Fundamentals guidelines out of the box. You can use Google Web Starter Kit to start creating new sites in minutes that follow all the best-practice guidance.
Being able to access these external files fully helps Google algorithms detect your site’s responsive web design configuration and treat it appropriately. You can use the Fetch and render as Google feature in Webmaster Tools to test how the indexing algorithms see your website.
