The internet is now the only source of advertising revenue growth for Yell as advertisers desert its printed directory.
The directories company revealed that pre-tax profits dropped by 44% from £155.9m to £87.2m for the six months to 30 September. But in the UK, it reported a 3% increase in revenue to £351.6m, which was driven entirely by Yell.com.
It saw its income rise 67% to £42.9m with the number of advertisers up 14.5% to 182,000. There was also a 41% increase in revenue per advertiser, as they paid for higher value products.
Yell also reported that the number of unique users of the website was up by almost 35% in September but the number of searches was only up 16%, which it claims shows that the site is more effective and users make fewer searches.
In contrast, it says the number of print advertisers fell by 3.7% to 235,000 in the UK.
US revenues are also growing with a strong performance by its online operations. Overall it grew by 23% to £455m with online revenues up 69% to $29.7m.
