A claim that OnTheMarket will not catch up with Zoopla “any time soon” was last night totally rejected by OTM.

The challenger portal also made clear that it still plans to do just that – and soon.

The site said that more than 4,800 offices are now signed up to OnTheMarket.

It hit back heavily at claims by search engine Home, saying Home had barely dented the market after 18 years.

OTM re-emphasised that it still expects to replace Zoopla as the number two portal within a year, underlining plans to be a “full alternative to Rightmove”.

Property search engine Home sent out a press release using its own figures. These included that OTM has made inroads into Zoopla’s market share but has failed to make any impact on Rightmove.

But last night, Home’s claims were totally shredded by OTM.

Two attempts by Eye inviting Home to clarify its figures have so far been unanswered.

In its release, Home, purely looking at sales agents and also looking at Zoopla and PrimeLocation separately, said that OTM is lying in fifth place behind Rightmove, Zoopla, PrimeLocation and Mouseprice. It says OTM is “just ahead” of sixth-placed Nethouseprices.

According to Home, there are 4,927 agents’ offices signed up to OTM as of March 10. This is higher than the latest figure given by OTM itself  and  very close to its launch target of 5,000.

Home says that at OTM’s launch date on January 26, Zoopla had 10,712 sales agency offices. By March 10, this had fallen to 9,072.

However, said Home, Rightmove’s tally of 12,850 sales agency offices has barely moved, down to 12,712.

Home says that looking further back, the figures show that many of those who jumped ship from Zoopla did so before OTM’s launch.

On December 15, Zoopla had 12,218 agents which, Home claims, means the portal has suffered an exodus of 3,146 agents’ offices over the last three months. Over the same period Rightmove lost 144.

On this evidence, says Home, OTM looks a long way from its aim of breaking into the top two at the expense of Zoopla. Moreover, it claims, some 600 OTM agents have yet to get clients’ properties uploaded to the new portal.

Home also claimed there is also emerging evidence that the exodus from Zoopla is tapering off, making OTM’s task tougher in the months ahead. According to Home, on March 10 there were 6,933 agents continuing to use both Zoopla and Rightmove, a tally that has fallen by just 108 since February 25, compared with a fall of 1,142 between January 27 and February 2.

Eye has asked Doug Shephard, of Home, for further information as to its figures.

We have had no response from Home but last night Ian Springett, CEO of OTM, told Eye: “Mr Shepherd’s comments on the Agents’ Mutual strategy and the progress of OnTheMarket.com are inaccurate and misleading.

“For example, he fails to mention that OnTheMarket.com is already getting more consumer traffic than Home.co.uk, Mouseprice and NetHousePrices put together.

“If Alexa is used as a measure, it is their UK rankings which are most relevant. After only eight weeks since its launch, OnTheMarket.com is already ranked at 604, placing it among the country’s most visited websites.

“Meanwhile, Home.co.uk is ranked at 2,789 after more than 18 years.

“Our progress will continue as we add more members and properties, extend consumer awareness as our multi-million pound advertising campaign continues, and begin to gain high rankings on major search engines.

“Our entry to the portals market increases competition.

“No agent or consumer has any less choice than they had before.

“OnTheMarket.com provides agents with a superb environment for advertising their clients’ properties with a slick and fast search and results pages which are uncluttered with intrusive third party advertising or unhelpful data included without their consent on their full details pages.

“The great majority of the 4,800+ agent offices which have joined OnTheMarket.com over the last 15 months have left Zoopla to do so. We expect to continue adding members at a similarly rapid rate over the coming year.

“If these new members make similar choices, we will replace Zoopla as the number two portal within a year and be in a position to develop into a full alternative to Rightmove for them.

“Mr Shepherd’s company uses agents’ data without their consent for its own commercial benefit. It helps sustain the current portals duopoly by sending leads via Zoopla and Rightmove rather than directly to the agent.

“Therefore, it is another example of a ‘service provider’ out of touch with current agent sentiment and with the strength of commitment of the member firms of OnTheMarket.com in doing what it takes to make the venture a success.

“It is unsurprising that Mr Shepherd should oppose a competing portal owned by more than 2,500 independent firms of estate and lettings agents which aims to disrupt that duopoly.”
