A common annoyance for web users
is when websites require browser technologies that are not supported by their
device. When users access such pages, they may see nothing but a blank space or
miss out a large portion of the page's contents.
Starting today, we will indicate
to searchers when our algorithms detect pages that may not work on their
devices. For example, 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 multi-device websites
Fortunately, making websites that
work on all modern devices is not that hard: websites can use HTML5 since 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 Starter Kit: a starter framework supporting the Web Fundamentals best practices out of the box.
By following the best practices
described in Web Fundamentals you can build a responsive web design, which has
long been Google's recommendation for search-friendly sites. Be sure not to
block crawling of any Googlebot of the page assets (CSS, JavaScript, and
images) using robots.txt or otherwise. Being able to access these external
files fully helps our 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 our indexing algorithms see your
site.
