Tracking of how consumers made purchases online over the Black Friday weekend by ChannelAdvisor finds that 40 percent used mobile devices. That percentage runs counter to a new survey from research firm Ovum, which says are likely to remain dominant. But “Cyber Monday” data might skew ChannelAdvisor’s findings.

Well, maybe not. We’ll see.

Overall Cyber Monday traffic surged, Wingo wrote in a blog Monday evening.

Google Shopping traffic jumped 133.5 percent over last year,ChannelAdvisor CEO Scot Wingo wrote in a blog.

“Overall it looks like Cyber Monday is (still) on track to be up over 30% compared to last year,” Wingro wrote at 6 p.m. Monday, “which would make it a new record day for e-commerce!”

Wingo reported similar gains for Black Friday online sales.

And mobile could be a big driver as it was earlier.

“By far the most interesting data point we see in the data … is the mobile trend,” wrote Scot Wingo, chief executive officer of global ecommerce services provider ChannelAdvisor (NYSE: ECOM), in his blog before the evening post.

“We are now squarely over 40% of traffic coming from phone+tablet with phone at 21.5% and tablet at 18.9%.

“Last year the trend was a spike on Thanksgiving and then the mobile settled down to the 30% range. Now we see it increasing from Thanksgiving – this is definitely a change in consumer behavior and it will be interesting to see if it holds through Cyber Monday (historically has been computer driven) and through the rest of December.”

Two pie charts reproduced with this post show that data.

Overall, mobile device shopping surged to 40 percent from 31 percent a year ago.

Those smartphone buyers led the way, making up 21 percent of mobile sales vs. 15 percent a year earlier.

However, if one reads the latest survey from U.K.-based research firm Ovum, one would expect PCs to remain dominant.

Ovum said its survey of more than 15,000 consumers across 15 global markets found that 68 percent of buyers prefer PCs or laptops over tablets and phones.

“According to the findings, the reluctance to use a mobile device stems from perceptions that services are not secure (49% of respondents) or that personal data might be misused (47%),” Ovum reported Monday.

Ovum also says that 50 percent of respondents have “no interest” in trying mobile payments. 

OK, but that still means 50 percent just might make a purchase, right?

Well, Ovum sees matters differently.

“The implications of these findings are profound for the growing mobile commerce ecosystem, as when it comes to digital commerce, consumers clearly still feel more comfortable with their PC and laptop,” says Angel Dobardziev, principal analyst at Ovum, in summing up the survey. “This shows that operator strategies that factor in rapid adoption of mobile commerce services need a reality check. Furthermore, the industry must design services that build on users’ comfort with e-commerce over the PC and extend it to the m-commerce domain.

“There is no doubt that eventually we’ll see mobile devices used for the majority of our online services, but in the m-commerce sector there is still some way to go,” he added. “To succeed, service providers will need to carefully understand and effectively address the subtle differences that concerned consumers have with using mobile money and mobile commerce services.”

Based on what Wingo and ChannelAdvisor found, however, a lot of providers and retailers must be relieving buyers’ concerns.
