Twitter to charge publishers for use

Twitter has followed yesterday's announcement that it plans to ban third-party ad services by saying it will now charge publishers to use the micro-blogging site.

The move to block third-party ad networks using Twitter sounds the death knell for services such as TweetUp, the so-called “AdSense for Twitter”, as the site gears up for the launch of its own Sponsored Tweet programme.

Today's announced change to the terms of use for the Twitter API require publishers to share some of the ad revenue that generate from pages featuring embedded Twitter content.

Explaining its move, Twitter said: "We encourage you to create advertising opportunities around Twitter content that are compliant with [its new rules]. In cases where Twitter content is the basis (in whole or in part) of the advertising sale, we require you to compensate us."

Not all publishers appear frightened by the move, however. News site The Huffington Post, which launched a Twitter-specific version of its site last month, told Business Insider: “We think we will be able to build a profitable business around Twitter content."

“It's all about what kind of partnership you can form with them," said an upbeat Huffington Post CEO Eric Hippeau. "We are big users of Twitter on our site and we’ve given them an enormous amount of exposure as well.”
