Monday: Bunk Article Takedown Day
1. The shift to mobile is well documented. In fact, even Business Insider reported that companies NOT optimized for mobile were missing out on sales.. In November of 2014 (I guess they're late on reporting on a lot of things) http://www.businessinsider.com/retailers-missing-huge-opportunity-on-mobile-web-2014-11
If you care about selling crap online, you knew this was coming.
2. Google's best practices advocate responsive design, and have for quite some time. A responsive site will display properly on mobile. Major CMS platforms built responsive design into their platforms, including some of the big eCommerce guns. (those that don't can be modified relatively easily)
If you've modified your website since 2008, you knew this was coming.
3. Google started tagging websites as "Mobile Friendly" in search results months ago. This was well documented on sites that cover Google updates.
If you've used your phone to search for local things since Christmas, you knew this was coming.
4. Google announced THIS CHANGE in February via their official blog. This made it's way out to quite a few news sites. They even published a tool that will tell you if your site will be hit by this change. This is pretty unprecedented for the company because they DON'T want to punish businesses with this change.
If you pay attention to Google news, which you should if you care about your site's SERP position, you knew this was coming.
5. This change will only impact Organic, mobile search results. If they are searching from their tablets or desktop, it's fine.If you follow other best practices but ignore this one and your website shows up in the Local Carousel, you're fine.If they're searching in maps, you're fine.
If you care that much about Google organic SERPS, you knew this change was coming.
