At the close of last month's Search Marketing Expo (SMX) West, conference speakers were asked to share their key takeaways.
"Mobile, mobile, mobile," said Kelly Wrather, senior manager of content marketing for Kenshoo and an SMX presenter. "I want to grab every website designer and tell them mobile is the thing! It's the only thing!"
At previous SMX shows the importance of mobile-optimized websites was a frequent topic of discussion, but this year, as Wrather's declaration illustrates, there was a sense of urgency because "Mobilegeddon," as some are calling it, is nearly here.
On April 21, Google will expand its "mobile-friendly" search result rankings, and the company says the changes will have an even bigger impact on search than its past Panda and Penguin algorithm updates. The Penguin update affected about four percent of global searches, and Panda impacted about 12 percent of English-language searches, according to Search Engine Land, so the new mobile-friendly update has the attention of everyone in the SEO community right now.
Here's what you need to know to prepare for Mobilegeddon.
Mobilegeddon, and how we got here
A website mobile-friendliness has been a search ranking factor for two years. The April 21 algorithm change means mobile-friendliness will become an even more important ranking factor, according to Jayson DeMers, founder and CEO, AudienceBloom. "Websites that aren't mobile-friendly will see a more negative impact in search visibility than they may already be seeing, and mobile-optimized sites may be rewarded even greater in search rankings," DeMers says.
In June 2013, Google wrote on its Webmaster Central Blog that it planned to roll out "several ranking changes in the near future" to "address sites that are misconfigured for smartphone users."
At that time, Google outlined two typical mistakes that can cause websites to deliver poor mobile experiences: faulty redirects for site pages listed in search results that send smartphone users to a single mobile page, such as the home page, instead of a mobile-optimized version of the page users want; and smartphone-only errors, which occur when smartphone users click Web pages listed in search results and only see error messages.

More recently, on February 26, 2015, Google announced via its Webmaster Central Blog two "important changes to help users discover more mobile-friendly content" on their mobile devices.
The first change, coming on April 21, will be to deliver "more mobile-friendly websites in search results" on mobile devices. With this update, the search giant will expand its use of mobile-friendliness as a ranking signal, and it will affect mobile searches "in all languages worldwide."
Google's mobile-friendly algorithm will "have a significant impact in our search results," giving mobile users easier access to "relevant, high-quality search results" optimized for mobile devices, the company says.
As for the second change, Google also announced in February that apps indexed through Google App Indexing would immediately begin ranking higher in mobile search. So if you're signed into your Google account, content within the apps on your mobile device will rank higher in search results than it would have ranked previously.
For example, let's say you have the OpenTable app installed on your Android smartphone. Using that same device, you perform a Google search for a restaurant. If that restaurant is listed on OpenTable, a "deep link" to its page in the OpenTable app will be included prominently among the other search results. Currently, Google App Indexing only works on Android. For more details, check out Google's App Indexing for Google Search pages for developers.
What you should know moving forward
Google's mobile-friendly algorithm "will be a page-specific influence, meaning that if some pages on a specific site are mobile-aware and others aren't, those with the mobile-friendly design will get a boost on mobile searches," says Thomas Petty, president, Bay Area Search Engine Academy.
The new algorithm will give mobile-optimized pages an "instant" boost in search results, according to Petty. "If Google has previously indexed your site, and your site wasn't mobile-aware at the time, and the next time Google comes to a specific page of your site that now is mobile-aware, that page will get an instant boost in mobile searches," he says.
Given how much emphasis Google is placing on mobile-friendliness, the algorithm could also directly or indirectly impact desktop search result rankings right away, or at some point in the future.
"Google has been notifying website owners for several months now in Google Webmaster Tools if their website isn't mobile-aware," Petty says. "I believe mobile-awareness will continue to be an influence on the good experience that Google wants users to have on all the various devices we carry."
Visibility in mobile search results could inadvertently impact desktop search rankings, according to DeMers. "The most significant current ranking factor is quality and quantity of inbound links to a website or page," he says. "One of the ways websites accrue inbound links is through their content being linked to as a resource."
If journalists, columnists, bloggers and others who are likely to link to that content can't find it on mobile devices, the content may not acquire as many links as it might have otherwise. Fewer links could therefore diminish content search rankings in desktop searches as well as mobile. "So a lack of visibility in mobile searches might negatively affect desktop search visibility as well," DeMers says.
Google algorithm updates also tend to penalize sites "across the board," says Arham Khan, senior digital marketing executive, HighQ. If a site is penalized for not being mobile-friendly in mobile searches, it will also likely be penalized in desktop searches, he says.
