OnTheMarket is to launch a new round of TV advertising this month.
Its advert will appear on over 40 channels, including Sky 1, Sky Sports and Sky News, although not on ITV.
The portal also said yesterday that it will continue its ‘heavyweight’ investment in paid search on Google.
The portal, which is coming up to its second birthday and which faces legal action next month involving two member agents and its ‘one other portal’ rule, has also released a new round of testimonials.
Peter Symons, a senior partner at Stags in the west country, said OTM is providing it with 25% of its portal leads.
He said OTM’s performance has been “absolutely outstanding”.
He went on: “It provides our 20 offices with very good quality leads and we believe it is therefore good value for money. I believe OTM attracts a high proportion of its visits from strongly committed buyers rather than casual browsers.
“We never expected its lead generation to rival the industry leader in the short term, but at this stage – after less than two years – the portal has certainly made its mark.”
Tim des Forges, sales director at JLL in Knightsbridge, said: “In terms of the volume of quality leads, OnTheMarket performs better for us than Rightmove. After less than two years and up against two very well-known portals, we feel it is making very significant inroads.”
Simon Hill, managing director of Michael Graham, which has 14 offices across Bedfordshire, Buckinghamshire, Cambridgeshire, Hertfordshire, Leicestershire, Northamptonshire, Oxfordshire, Warwickshire and central London, said: “The enquiries we receive from OTM tend to be of a very high quality which is key if we are to deliver the best possible service to our vendor clients.
“The impact of removing our properties from Zoopla has been minimal because the leads we received were often from casual browsers who were not genuine buyers or tenants.”
OTM chief executive Ian Springett said: “These statements of endorsement from large and well-known firms are testament to just how far OTM has come and how it continues to progress and perform for its agents.
“As we approach the portal’s second birthday, we look forward to building on our successes, and we remain as committed as ever to our long-term strategic objective of building the best portal for agents and consumers alike.”
