The amount of information streaming in about mobile search every day can easily become overwhelming.
One thing that we know for sure when it comes to mobile SEO best practices: Google has made it clear that a bad mobile user experience will result in poor rankings in their mobile search results.
What follows are some starting points about how to use your mobile engagement performance to identify common issues and fix them.
Mobile Site Configuration
Google supports and has solutions for most mobile site configurations, which we can generally categorize by whether a site has unique mobile URLs.
Same URL for Both Mobile and Desktop
Google has come out in support of responsive design, preferring the method of detecting the screen width of a mobile device and serving the appropriate site content from a single URL.
Alternatively, rather than detect the width of the user’s screen, many sites choose to identify the device type from the browser’s user agent string. Because there are so many possible user agent variations, this method is less preferred than the simpler screen width method, but if used, Google recommends adding Vary: User-Agent to the HTTP header of all applicable pages.
