Google has issued a fix for a mobile search bug that would redirect people to a website’s homepage instead of the results displayed. This would occur if a website wasn’t properly optimized to handle requests from smartphones and as a result a user would be redirected to mobile version of a site’s homepage instead. Starting today, Google will provide users with a warning that their search “may open the site’s homepage,” but will still offer a chance to try to visit the results displayed.
For now this feature is only works with English search results in the US and if a website redirects a smartphone user to its homepage, Google will send the site’s admin a message in Webmaster Tools’ Smartphone Crawl Errors section. So, if you operate a website that has this issue, prepare to have your inbox slammed.
