Rightmove has sent out a long questionnaire to agents which essentially asks them what they think of challenger portal OnTheMarket.

By contrast, the questionnaire asks barely any questions that mention Zoopla, and appears to underline just how seriously Rightmove is taking OTM, six months after its launch.

For example, the questionnaire asks agents to say how likely they would be to recommend first Rightmove, and then OTM, and to say why in each case. But it does not ask that question about Zoopla.

In a series of 17 questions, it also asks agents to list the most and least important reasons for using a property portal – for example, whether the portal resolves queries in a timely way, rewards loyalty, understands agents’ needs, or makes agents feel as though they’re in control of the relationship.

It also asks agents to say whether important reasons for using a portal are because it is willing to negotiate on price, generates quality leads, and cares about its customers.

In the following 28 questions, it asks agents specifically to rate Rightmove and OTM on a range of specific points, including friendliness and approachability.

More questions follow, but only a handful ask agents to assess Zoopla alongside Rightmove and OTM.

Three statements ask agents to evaluate the statements: “My company couldn’t operate without this portal”; “A brand that is only in business for themselves” and “A brand that knows what it stands for”.

The questionnaire also asks a number of questions about Rightmove’s and OTM’s account managers.

Agents are introduced to the survey with Rightmove saying that it wants to “design our plans with you in mind”.

The survey is conducted by independent market research company Jigsaw Research, and offers ten prizes of £100 worth of Amazon vouchers.

A spokesperson for Rightmove said: “In order to make Rightmove work better for agents, we are asking our members how our product, services and customer relationships compare to the other options that they may have.

“Our aim is to improve Rightmove for agents. This wide ranging survey is being conducted by an independent third party.”
