Continuing the previous list of mobile predictions, here are five more trends to watch for in 2012. Don’t forget to add your own predictions by leaving a comment below.

Prediction 6: In-App Search Will Overtake Browser-based Search

According to our Q3 2011 Mobile-Local Search Stats network report, browser search still takes the cake (due, in part, to feature phones and the convenience of using browsers to find local businesses versus loading an app every time). But in-app search is growing faster as the smartphone market heats up. If the pace continues, in-app search will overtake its browser counterpart by the end of Q1 2012 (it’ll be interesting to see if in-app search will be able to maintain its supremacy; see Prediction #8).

But advertisers looking for a clear-cut answer regarding which platform to focus on in 2012 should know that a browser-only or app-only strategy won’t cut it. By sacrificing one for the other, you’re essentially isolating millions of searching, purchase-ready consumers, so you really must adopt a complete mobile solution.

Prediction 7: The “App or Mobile Website?” Debate Will Continue

Based on the previous prediction, businesses will continue to debate developing a dedicated app versus a mobile site. If you have the resources and budget to develop, maintain and constantly drive traffic to your own app, more power to you. But the recent holiday season resulted in a major influx in retailers’ mobile-Web traffic because consumers reportedly researched deals on Thanksgiving before hitting their local stores in record-setting numbers over the holiday weekend. It’s not just a one-time phenomenon either, as Morgan Stanley expects the mobile Internet to overtake the traditional Internet in terms of traffic by 2014.

Based on that, most businesses will benefit more from a mobile-friendly site, coupled with search and display ads in apps. But no matter what happens, app saturation will continue, as Android and Apple boast millions of downloadable apps. In that light, businesses will need to focus on the top-used apps; if you’re confused about how to proceed, consult a mobile-marketing partner (shameless plug).

Prediction 8: HTML5 Will Be the “One to Rule Them All”

The mobile landscape is in dire need of a great unifier, one to rule them all. In 2011, Adobe dropped Flash support for mobile browsers (but kept it for app-based development), proving that HTML5 could be the long-awaited savior for the fragmentation problem, although the problem will not entirely disappear in 2012.

HTML5 has crawled so far, but it will pick up momentum in 2012 as more businesses seek to develop mobile-dedicated sites. And with the HTML5 being positioned as the new standard (HTML5 is universally accepted on major mobile devices), designing and optimizing a mobile site should be easier and more economical for mobile-confused, budget-strapped businesses. In the same breath, agencies like the Mobile Marketing Association will continue to create standards-compliant guidelines for mobile ads.

Finally, as HTML5 entices more businesses to develop mobile-friendly sites, the mobile-Web experience will vastly improve, which could throw a wrench in Prediction #6 playing out past Q1 2012.

Prediction 9: Voice-Activated Search Will Force Job Descriptions to Be Rewritten

Voice-activated systems like Apple’s Siri are already causing a buzz in the industry, especially among content optimizers who are concerned over what Siri means for mobile SEO. Because features like Siri complement the mobile lifestyle of multitasking, they will become commonplace on more phones released in 2012.

But since voice-activated search is still in its infancy, consider it a work in progress. New standards and best practices will likely be developed over the next year. As that happens, expect your job description to change to take on the burgeoning sector of voice-activated search.

Prediction 10: Phones Will Replace GPS Systems

Remember that device you bought years ago to accompany you on your driving excursions? In 2012, stand-alone GPS systems will be rendered nearly obsolete (will digital cameras be next?) because of smartphone functionality. More consumers will stop wasting dollars on multiple devices when they can invest in single devices that are versatile. Sure, people may still use their stand-alone GPS systems, but you can bet sales will be way down.
