Marketing for internet mobiles has to get over the annoyance factor and the problem of unsolicited content - something that text-marketing has not managed.

That's according to analyst firm Frost & Sullivan, which thinks that online marketing services are getting the attractions of mobile internet advertising - how cost-effective and flexible it is for example - without finding the "right fit" for mobile advertising.

One of the company's analysts, Jeff Teh, thinks that mobiles have huge potential as an advertising medium.

"Unlike traditional media which mainly delivers content, mobile advertising has the ability to also deliver services and personalised content to consumers," he said.

He feels that an ad-funded model, where subscribers get free content in exchange for receiving adverts, could prove effective.

The figures certainly seem to support the idea that people are using their mobiles for internet access more and more - comScore reported an increase of 38 and 68 per cent for the Europe and USA respectively in terms of mobile searches in June compared with June 2007.

So while consumers are taking advantage of mobile internet, how best can advertisers take advantage of this trend?
