People seeing Rightmove adverts were so disbelieving of the claims that they complained to the Advertising Standards Authority.

The adverts, on the London underground, claimed that every second someone contacts an estate agent about a home on Rightmove.

One poster said: “Every second someone in the world gets married and every second someone contacts an estate agent about a home on Rightmove.”

A second poster said: “Every second a bee flaps its wings 230 times and every second someone contacts an estate agent about a home on Rightmove.”

Three people challenged whether someone really did contact an agent every second about a property listed on Rightmove.

Rightmove told the ASA that there were 31.5m seconds in a year, and that it received 42m leads annually, equating to 1.3 enquiries every second.

The ASA did not uphold the complaints.
