Smartphone users are a significant and fast growing segment of Internet users, and at Google we want them to experience the full richness of the web. As part of our efforts to improve the mobile web, we published our recommendations and the most common configuration mistakes.
Avoiding these mistakes helps your smartphone users engage with your site fully and helps searchers find what they're looking for faster. To improve the search experience for smartphone users and address their pain points, we plan to roll out several ranking changes in the near future that address sites that are misconfigured for smartphone users.
Let's now look at two of the most common mistakes and how to fix them.
Faulty redirectsSome websites use separate URLs to serve desktop and smartphone users. A faulty redirect is when a desktop page redirects smartphone users to an irrelevant page on the smartphone-optimized website. A typical example is when all pages on the desktop site redirect smartphone users to the homepage of the smartphone-optimized site. For example, in the figure below, the redirects shown as red arrows are considered faulty:
Avoiding irrelevant redirects is very easy: Simply redirect smartphone users from a desktop page to its equivalent smartphone-optimized page. If the content doesn't exist in a smartphone-friendly format, showing the desktop content is better than redirecting to an irrelevant page.
We have more tips about redirects, and be sure to read our recommendations for having separate URLs for desktop and smartphone users.
Smartphone-only errorsSome sites serve content to desktop users accessing a URL but show an error page to smartphone users. There are many scenarios where smartphone-only errors are seen. Some common ones are:
- If you recognize a user is visiting a desktop page from a mobile device and you have an equivalent smartphone-friendly page at a different URL, redirect them to that URL instead of serving a 404 or a soft 404 page.
- Make sure that the smartphone-friendly page itself is not an error page. If your content is not available in a smartphone-friendly format, serve the desktop page instead. Showing the content the user was looking for is a much better experience than showing an error page.
- Incorrectly handling Googlebot-Mobile. A typical mistake is when Googlebot-Mobile for smartphones is incorrectly redirected to the website optimized for feature phones which, in turn, redirects Googlebot-Mobile for smartphones back to desktop site. This results in infinite redirect loop, which we recognize as error.
Avoiding this mistake is easy: All Googlebot-Mobile user-agents identify themselves as specific mobile devices, and you should treat these Googlebot user-agents exactly like you would treat these devices. For example, Googlebot-Mobile for smartphones currently identifies itself as an iPhone and you should serve it the same response an iPhone user would get.
- Unplayable videos on smartphone devices. Many websites embed videos in a way that works well on desktops but is unplayable on smartphone devices. For example, if content requires Adobe Flash, it won't be playable on an iPhone or on Android versions 4.1 and higher.
