Mobile Sites build Trust
Mobile has become more and more critical.
In addition to making sure your website's visitors (including your blog's visitors) have the best experience possible, optimising for mobile will score your website some serious SEO points.
Google analyses every page submitted to it. Before publicising your post or page, make sure it looks good on your computer and your mobile.
Mobile is now one of the most important ways in which websites are analysed; Google will check to see if it load quickly, if it is useable on a mobile, does it give the audience the answer they’re looking for?
Google will know the difference, as will your audience.
