The publisher of titles including Drapers, Health Service Journal and Retail Week will offer users subscription packages as it looks to ramp up digital revenues.
Retail Week will introduce a pay wall on 13 November. It is thought a time frame has not yet been finalised for other websites.
The move marks a U-turn by the publisher, which last year said it would dispense with pay walls across the majority of its magazine websites.
Emap was bought by Guardian Media Group and Apax Partners for £1.2bn two years ago.
