Ad tags in emails give publishers the ability to drive revenue one click closer, helping to fund email programs. The alliance created by LiveIntent, which sells email ad inventory similar to display, supports publishers and email service providers to ensure compatibility between technologies and campaigns.

Familiarity breeds use -- especially when it comes to technology. Apple did it through hardware; Microsoft, software. Search marketers familiar with keyword contextual targeting on the Google Display Network can now take that same process through Simpli.fi's demand side platform (DSP) and target ads through about a dozen ad exchanges by leveraging familiarity in a workflow that search marketers already use.

At the Mobile World Congress in Barcelona, Google Global Head of Mobile Sales and Strategy Jason Spero revealed to an audience on Monday a dozen predictions and mobile trends for 2012, mostly in Europe. But analysts made their own predictions, suggesting that Google will pull in from mobile about $4.5 billion in revenue during its fiscal year 2012

AdGooroo has created a searchable database that allows agencies and advertisers to gain competitive analysis. The tool -- Industry Insight -- allows marketers to research competitive keywords, as well as compare the monthly amount spent on paid-search ads.

Jim Kruger, digital and social media manager at Buick, told OMMA Tablet Revolution conference attendees Thursday that tablets give brands the opportunity to reach a whole new generation of tech-savvy buyers and early adopters of technology. He said the carmaker continues to see Web site traffic from tablets rise about 23% sequentially.

Rather than type, speak the query. Searchers won't click -- they will swipe, touch or gesture. These expressions of intent on search engines or in applications will become the means by which people find and access information on Google, Bing and Yahoo, as well as Facebook, Twitter and Pinterest.

Pinterest supports more than 10 million unique monthly U.S. visitors, but how can search engine marketers tap into the growth? Digital search marketing agency Greenlight published a paper on Best Practices that search marketers will find valuable.

Privacy on the Internet does not exist. Technology enables Web browsers to track mobile or desktop interactions with Web sites and content. Whether intentional or by mistake, sensitive data -- even emails -- are duplicated as they traverse the Internet on their way from one outbox to another's inbox. No Web application or software can prevent the leak of information or data collection. And even if they do, there's always some smart tech whiz who can circumvent privacy settings.

Google+ has been viewed by some as an "extra extension" or channel, but marketers are beginning to realize its significance. Victoria Esser, who is Deputy Assistant Secretary of State for Digital Strategy in the Bureau of Public Affairs, writes in a blog post that social media offers a powerful way for the State Department to better inform, understand, and engage with the American people and communities around the world.

Waving your hands, speaking your thoughts, and touching the screen to interact with applications on smartphones, desktops, laptops, tablets and televisions might make you look like a lunatic to the casual observer, but these actions will become natural search techniques in the near future. These simple tasks will power innovation where a microphone and a webcam will replace the search box on engines and Web sites. That's not really a futuristic idea, considering apps like Apple Siri, Evi, Google Voice, and Microsoft Kinect.
