It looks as if keyword advertising is coming very soon to the mobile search arena.
A short article on the Netimperative site points out that Yahoo Search Marketing Services (formerly Overture) has signed a deal with Mobile Commerce to provide keyword ads, something we haven't seen much of on mobile services up to this point, on a new "mobile" travel search site that will launch later this year in the UK.
The three companies currently bidding the highest amount for those keywords will have their advertisement shown to the user...Sean Walker, general manager of vertical markets at Overture said: "This service is going to replicate the internet performance-based search advertising model, where companies bid and pay for advertising space in real time. "For us, this is a natural transition from the advertising we serve on the internet. Many of our existing advertisers are interested in this new method of distribution."
