To assist with the marketing of your company you might like to consider the various non-region specific phone numbers that are available, you could already be familiar with some of them, such as the 0800 number or the 0845 numbers, but there are more that you should also familiarise yourself with.
These numbers can be used to great effect in your marketing and in the tracking of the effectiveness of the marketing, for example if you are having a corporate event and you have got some help with your conference management you should brand all the literature and promotions with an 0800 freephone number that you only display in relation to the event.
Then when a caller calls you about your services on that number you know it was because of the marketing or the event itself, organisations like Windsor Telecom provide very detailed and useful statistics packages with their telephone number packages these can be used to see where people called from, what time the call was made and how long they were on the telephone for.
You can see this is valuable info when used in together with your on-line and off line marketing as you can see how much business you are getting from corporate events compared to newspaper ads or PPC ads on-line.
I know of a company who were able to reduce their costs by hundreds of pounds a year using this method recently in their recruitment.
They wanted some new secretarial support and placed an advertisement in the Bournemouth Echo, a local paper, an on-line PPC advertisement with keywords such as secretarial job Bournemouth and an ad on the local radio. These all had different 0800 numbers to call for details, the internet proved to be the most cost effective and as a result the organisation were able to spend more of their recruitment budget on-line rather than in print or on the radio.
Now this is only one example and on-line recruitment may not be the best way for everyone to attract new staff but using the different 0800 number options available you can test for yourself.
