BBC.com has an estimated 26.5 million visitors a month worldwide, according to research firm ComScore.

An "advertise with us" link appeared for the first time on BBC.com news pages beginning Thursday.

"This will give information about advertising, how to go about it, and we are updating our feedback terms and conditions pages," Pete Clifton, the BBC head of news interactive, said in an e-mail to news staff Thursday.

The next step is to deliver the first of the ads, which Mr Clifton indicated is probably going to happen from next month.

"In the first phase, advertising will be introduced on selected high-traffic pages visible only to those logging in from outside the UK," he added.

However, location-based blocking technology is still not perfect, and an estimated 3,000 users in the UK will inevitably see some of the ads.

According to Media Guardian, in spite of the desire to get advertising online and running as soon as possible on BBC.com, Mr. Clifton acknowledged the cautious approach that needs to be taken.

"It is likely to be some weeks before any ads appear on the internationally viewed site," Clifton said. "We will need to be completely sure that the day-to-day editorial and technical processes are in place before that happens."

The BBC Trust has approved the proposal for running ads on the international homepage and selected news, sport, weather, science and nature web pages.

BBC news will still hold the responsibility of editorial control of news pages, while bbc.com will pay for the content it uses.

Earlier this year, the BBC Trust requested additional information about the ad plans including the strategic benefit and editorial safeguards, saying that “advertising, if not properly governed, could dent the corporation's brand and reputation.“

Eventually, the BBC Trust gave the nod to advertising on BBC.com with several conditions - one is that “editorial performance must be closely monitored and reported on to the corporation's journalism board, which must notify the trust of 'any significant failure' in editorial control,” the Guardian reported.

Any future development of BBC.com will also require BBC Trust approval.

"We will not be offering highly intrusive advertising and are taking significant steps to manage any potential conflict of interest between advertisers and editorial content to ensure our journalism is not compromised in any way," Richard Sambrook, the BBC director of global news, said in a post on the BBC news editors' blog.

"We recognise that some users will be unhappy with this change. However, in tests and surveys in advance of this change, the majority of international users did not express a strong objection and a majority of those surveyed in the UK agreed with the principle of advertising for international users," the Guardian reported.
