Anyone who simply plonks a property on a portal and then waits for the phone to ring is not an estate agent.

Ed Mead, director of upmarket London agent Douglas & Gordon and a key mover behind OnTheMarket, said that the two big portals are about leads, not sales. He also claimed that online agents do not sell property.

He estimates that only about 1% of his firm’s sales are made to people who actually saw that specific property on a portal – and it could be even less.

The other enquirers are leads that go into the firm’s database for future sales, with six in ten of all buyers coming through portals. However, that still left 40% of buyers not coming through portals.

Mead said that access to an agent’s database of buyers is what sellers actually pay their fee for.

He said it was “utter rot” that selling property is simply about listing on a portal.

He described as “minuscule” the number of times his business sells to someone who first sees that property on Rightmove.

Mead said: “Rightmove and Zoopla are a medium for advertising, but it’s not where properties get sold.”

Mead admitted that in dropping Zoopla, his firm had lost some leads – but that the slack had been taken up by Rightmove.

He said: “OnTheMarket is designed to bolster what estate agents do – online estate agents do not sell property.”

EYE asked about the original strategy of building a portal by agents for agents, with the key pillar being to split listings between Rightmove and Zoopla. This has clearly not worked, but Mead said the strategy had not changed.

He said: “We have no power over individual agents – no one does.

“Agency is the last bastion of the true entrepreneur. How does anyone imagine for a moment they would agree to do anything someone else suggests, especially as the majority of agents are one-office operations?

“Rightmove now has the market power. Neither Zoopla nor OTM has market power.”

He added: “Clearly the portal has to stand on its own merits. From the agent perspective nothing has changed – build a clean, attractive and simple portal that advertises clients’ properties to best effect and to their best interests.”

He emphasised the lack of external shareholders or third party advertisers.

Mead also said that agents who expected OTM to become a Rightmove or Zoopla overnight ignored the fact that they had huge budgets for marketing, plus SEO traffic gained over an extended period of time.

Mead said: “OnTheMarket on behalf of its members is proud of what it has achieved in 15 months. And despite headwinds from competitors, momentum is good and it’s here to stay.”

Regarding Mead’s claims that such a very tiny number of Douglas & Gordon’s eventual buyers have first seen the property on Rightmove, he said: “We’re starting to track that number, but less than 1%. Those are our initial figures. The leads we get are not as qualified as those who call us – they tend to be browsers”

Mead said that OTM could become more than a portal, and grow into an industry resource for people wanting to know about property.

He said: “If you want to know about property, you talk to people who know about property. That’s agents. OTM is by agents, for agents. The professionals who own the website understand property.

“Zoopla and Rightmove don’t know property. They just advertise listings.”

Ed Mead is also on the board of the Property Ombudsman.

*  Eye would like to make a request: we spoke to a number of agents for this story and all had no data tracking the source of buyer leads that eventually bought or rented a property. Is there truth in the assertion that ‘properties aren’t sold online’? We’d like to find out.

The agents we spoke to all agreed to start tracking that data for the next month.
