Starting on Tuesday, April 21, 2015, Google is going to make a massive change to the way it ranks websites. How massive? This change outranks both Panda and Penguin in terms of its scale of impact on search results, according to Google’s Webmaster Trends analyst Zineb Ait Bahajji.

The change comes down to one very important criterion: whether your website, landing pages, and blog are fully optimized for mobile.

They explain:

Starting April 21, we will be expanding our use of mobile-friendliness as a ranking signal. This change will affect mobile searches in all languages worldwide and will have a significant impact in our search results. Consequently, users will find it easier to get relevant, high quality search results that are optimized for their devices.

If your site isn’t fully optimized for mobile devices, you will likely see a hit to your ranking on mobile searches.

Don’t know if your site is optimized for mobile? Google makes it easy. Namely, they’ve provided website owners with free tool well in advance to tell them exactly what is needed to prepare for the new mobile search algorithm.

You can access the tool here.

When you run your site on the tool, you’ll get a quick assessment of whether your mobile rank will suffer as a result of the April 21 change. If your website is fully optimized for mobile, you’ll get a success message like this one:


As you can see, I also have to update my site this week! As owner, my own website is like the “cobbler’s children who have no shoes”! So, I have some work to do on my own this weekend!

Often, making a site mobile optimized requires a new WordPress theme or at least an update. If you need an assessment on how to do this, please contact me at or call 970-903-3605.
