McGrane also noted the problems faced by users arriving from search engines: "If you're only delivering a subset of content and features on your mobile site, redirecting users to the mobile URL can cause huge problems. This scenario happens all the time: the user searches for something on Google from her phone, and finds the content she's looking for. Tapping the link in search results takes her to the mobile site, but because that content doesn't exist on mobile, she gets dumped on the mobile homepage. Sure, she can link to the full desktop site, but she winds up on the homepage there too. She knows the content exists, she just can't get to it anymore. Redirecting to the mobile URL breaks Google search. How is that ever a good user experience?"
