Apart from getting bought by Google, we mean.
Russell Buckley from AdMob explained to the audience at Monetising Mobile tonight how mobile advertising can pay off for app developers.
It's a good week for AdMob, since its $750 million acquisition by Google has just been waved through by the Federal Trade Commission in the US.
"We're doing a lot of work these days in video," he said. "Last year we saw our first million-dollar campaign, just with AdMob, from Land Rover. Those sort of numbers are beginning to pump more and more into the system."
He also talked about games developer Backflip Studios, who are making more than $100,000 a month from AdMob ad units within their games. Ads are now 50% of the developer's monthly revenues.
Buckey also gave advice on how developers can make money from ads. "Make sure you're not interrupting the consumer experience," he stressed.
"If you're publishing a game, you probably want to have advertising before or after the game, not during it, for example."
Buckley also talked about the benefits developers can get from promoting their own apps, either from ads in other apps, or 'house ads' in their own apps.
AdMob has seen several partners vault apps into the Top 20 of the iPhone App Store through these kind of promotions.
"A typical campaign of that size is about $15,000, and it gets you up there," said Buckley.
