The problem with some advertising is it's very hard to know how well it's actually working. But with Yellow Pages Group® it's easy. We give you the tools to track the effectiveness of your Yellow® display ad with our free Call Monitoring service*.

With Call Monitoring you'll see how many calls your display ad in the Yellow book is driving to your business. If your business qualifies for this free 12 month service, you will receive the benefits of:
- Monthly reporting on call volumes generated by your Yellow display ad.
- Graphical displays so you can see at a glance call volumes by month.
- Up to date analysis which can be used to improve and fine tune future advertising performance.
- We can also talk to you about how your display ad compares with others in your classification, or of the same size.

Call Monitoring measures call volumes through a unique phone number that appears only in your display ad in the Yellow book**. Here's how it works:
- We provide you with a unique Call Monitoring phone number that is similar to your existing business landline number.
- To measure the number of calls generated by your ad, the unique phone number appears only in your Yellow display ad. It is also the only number that appears in your Yellow display ad. Please note – your existing business phone number will still appear in your standard listing in Yellow, and you can retain it for other advertising and for customers who already use it.
- Calls to your unique phone number are automatically diverted to your existing business phone number.

* Email us or call 0800 803 803 to find out if your business is eligible for our Call Monitoring service.
** This number may also appear on yellow.co.nz if your Yellow book display ad is shown online.
