OnTheMarket has passed the mark for 2m unique visitors.
It reached the number at the weekend.
The portal has also continued to grow numbers, with 4,800 contracted offices, up from 4,600 at launch on January 26, and up from the 4,700 announced on February 18.
Chief executive Ian Springett said: “It can no longer be questioned that we are now a major property portal as our traffic levels continue to show impressive growth and reflect very strong levels of interest and satisfaction among new and returning users.
“What’s more, we are providing high-quality leads for our member agents day in, day out.
“We state again that we are confident in becoming the number two portal within a year to replace Zoopla/PrimeLocation, and even after just a few weeks we are now stronger in certain areas of the country with our numbers of property listings.
“We have more than 4,800 contracted offices – 90% of which have chosen to leave Zoopla – and are growing in size as the impact of our multi-million pound advertising campaign hits home and our reputation as a cleaner, fresher and faster property website becomes firmly established.”
The statement, released early this morning, drew immediate attention from City analysts.
William Packer, of Exane BNP Paribas, said: “We see this as negative for Zoopla.”
Reiterating an “underperform” rating for Zoopla and “outperform” for Rightmove, he warned that there would be “further downgrades” by analysts if Zoopla “cannot start to regain members”.
