In a trading update, the publisher said overall group revenues for the period from January to the end of April rose 3% on the same period last year.
It said it had witnessed a slowdown in recruitment advertising across its stable of magazines, which include New Media Age and The Lawyer, but online recruitment advertising had more than made up for this decline.
Magazine-branded websites posted a 17% year-on-year rise in ad revenue in the four months to the end of April, while events attached to its titles had achieved "double-digit growth".
Centaur said its mortgage titles -- including Mortgage Strategy and Lending Strategy -- were among the worst-hit by the slowdown in the UK economy.
The company said: "The mortgage market has continued to deteriorate, although Centaur's share of this market has increased significantly in the past few months, partly offsetting the effect of market decline."
Despite the uncertain economic climate, the group said it expected "no material change to trading conditions" between now and the end of its financial year at the end of June.
Centaur has taken a number of actions to reduce costs, with the restructuring earlier this year of its marketing and creative division.
The move came after growing management concern about the company's share price on the Aim exchange, which has almost halved in the past 12 months from a high of 148.75p to 78p last night.
Shares in the publisher fell 3.3% this morning, down 2.5p to 75.5p.
