Although three-fourths of its audience accesses the site from outside the United Kingdom, the Mail Online's commercial focus will remain on the UK, the editorial director has said.

Martin Clarke told Journalism.co.uk that even though traffic from the United States is high, “all our efforts are focused on the UK traffic.”

UK traffic is what the Mail Online's advertisers are most interested in, he said.

“No British newspaper website – and we all have masses of traffic from abroad particularly the States – has really figured out how you effectively monetise it,” he is quoted as saying by Journalism.co.uk. “ take the view that if you produce a good site for UK users, then the international traffic will come automatically.”

But while the Mail Online keeps its focus on the UK, other papers there look to cash in on the growing American presence on their sites. The Guardian is looking to add additional reporters to its U.S. staff and target U.S. advertisers, Business Week reported.

The Mail last week reported receiving 9.2 million visitors, that's 78 percent of total unique users, and 58 percent of its page impressions in July from people accessing the site outside the UK, according to an ABCe audit. The same audit also found the Mail Online's nearly 12 million unique users is only second to the Guardian as the most accessed newspaper Web site in the UK.
