The BBC has confirmed its online budget will be cut 25%, resulting in the loss of 360 jobs.
It will cut about 200 websites as it reduces the amount of money it spends on its online output, according to a news report from the BBC.
The iPlayer will be re-shaped into a unified offering, bringing together programming and programming information with archive content, it said.
Mark Thompson, BBC director general, said: "BBC Online is a huge success, but our vast portfolio of websites means we sometimes fall short of expectation.
"A refocusing on our editorial priorities, a commitment to the highest quality standards and a more streamlined and collegiate way of working will help us transform BBC Online for the future."
BBC Trust Chairman, Sir Michael Lyons, said: "We are clear about the continuing importance of the BBC's Online service. But we want strengthened editorial vision and a more selective approach in the interests of both public value and market impact. This strategy is about doing fewer things better, and clearer boundaries."
The BBC is to see its overall budget cut by 16%, as £300m is due to be redirected from the licence fee to fund superfast broadband investment in rural areas, chancellor George Osborne said in his Comprehensive Spending Review.
