B.com have certainly stamed ahead. In the past it was WOTIF that was clearly the leader. When we took over this property we found that B.com was pulling huge numbers and I was very surprised. Nearly every second booking was from B.com. We soon realised that the rates were very low and raised them. This slowed the bookings via the internet.
WOTIF is now moving down the popularity scale.

For those who have not requested access to their listings, I recommend that you do. There is a wealth of statistical data available for your property and interesting comparisons to your competition.

As some of us here are doing, respond to every review. It helps to push your property up the list. They also have a direct link to your own website and OTA's. So guests can choose how to book.
