As a web developer I know this is going to not only effect my clients, but many other small businesses as well. I suggest if you know a business owner or are one… you read through this information and do whatever you can to make sure you are compliant. If you have any questions, please call me at 408.568.8889.
WHAT IS THE CONCEPT?
Users should get the most relevant and timely results, no matter if the information lives on mobile-friendly web pages or apps, whenever they are searching on a mobile device. This latest algorithm is adapted to take into account new usage patterns that favor mobile searches.
This update will boost the rankings of mobile-friendly pages (pages that are legible and usable on mobile devices) in mobile search results worldwide. Conversely, pages designed for only large screens may see a significant decrease in rankings in mobile search results.
- More mobile-friendly websites will appear in search results.
- This change will have a significant impact in our search results.
- Goal: for users to find it easier to get relevant, high quality search results that are optimized for their devices.
- Implementation: webmaster’s can make sure their sites are ready for the update by:
- More relevant app content in search results.
- Google is using information from indexed apps as a factor for ranking for signed-in users.
- Meaning: now content from indexed apps will surface more prominently in search results.
- There is a step-by-step guide for app developers on how to best leverage this feature.
- Will desktop and/or tablet ranking be affected by this change?
- NO – this update has no effect on searches from tablets or desktops.
- Is it a page-level or site-level mobile ranking boost?
- It’s a page-level change. Meaning, if ten of your site’s pages are mobile-friendly but the rest aren’t, only the ten mobile-friendly pages will be positively impacted.
- Unfortunately, my mobile-friendly pages won’t be ready until after April 21st. How long before they can be considered mobile-friendly in ranking?
- We determine whether a page is mobile-friendly every time it’s crawled and indexed — you don’t have to wait for another update. Once a page is mobile-friendly, you can wait for Googlebot for smartphones to naturally (re-)crawl and index the page or you can expedite processing by using Fetch as Google with Submit to Index in Webmaster Tools. For a large volume of URLs, consider submitting a sitemap. In the sitemap, if your mobile content uses pre-existing URLs (such as with Responsive Web Design or dynamic serving), also include the lastmod tag.
- If I see no drop in traffic on April 22nd, does that mean my site’s rankings aren’t impacted?
- You won’t be able to definitively determine whether your site’s rankings are impacted by the mobile-friendly update by April 22nd. It’ll be a week or so before it makes its way to all pages in the index.
- Can you be partially mobile-friendly? 
- No – a web page is or isn’t mobile friendly. It is a yes or no.
- Will this impact AdWords ads?
- No – this is only for organic listings. AdWords may have their own mobile factors but this is unrelated.
