As more consumers invest in tablets, marketers should note that these mobile audiences are heavily engaged online. A new report from Knowledge Networks suggests tablet owners spend 48 percent more time online than the average consumer.

Consumers with tablets spend four hours and 19 minutes on the internet each day (both via their mobile devices and PCs), compared to two hours and 55 minutes of daily online time among overall consumers. This demonstrates the fact that mobile audiences are always connected to the web, making them a valuable audience for businesses to target.

Brafton reported last month that tablet shipments are expected to increase to 250 million worldwide by 2015, paving the way for mobile devices to become the primary constant access point for the web.

The average tablet owner spends 55 minutes per day on his or her device, with 24 minutes dedicated to social media access, gaming and search. For marketers, the opportunity to reach tech-savvy consumers using the devices provides major potential for social media marketing and SEO strategies. Indeed, Google data suggests mobile search “never stops.”

According to Knowledge Network, mobile web access accounts for more than one-third of tablet owners’ time spent on the internet(38 percent). For the general 18- to 64-year-old population, mobile web use accounts for just 14 percent of online time.

“To keep messaging effectively, marketers need an integrated view of their targets’ technology and media habits – where they are in today’s world of ‘anytime-anywhere’ access to content,” Robert DeFelice, vice president of client service at Knowledge Networks, said in a release.

The latest entry into the evolving tablet market, the Amazon Kindle Fire, has led some to expand their expectations of tablets moving forward. Brafton reported on Wednesday that the rapid pre-sales of the tablet may provide the first major competition for Apple’s iPad.
