I have run into some difficulty with News Ltd publications here in Australia. New Ltd publications do not allow advertisers to include a url in a newspaper classified. Unfortunately they have a near monopoly for community papers in Australia.
I am left with only a small number of community papers nationwide that will print a url. One workaround I have tried is to include a mobile phone number in the print ad. The phone number simply plays a voicemail message which directs callers to visit the website. This method does work but must reduce the traffic inflow to a small percentage of the potential traffic generated if the url was in the ad.
Another technique is to spell out the words in a domain name then place this in bold at the bottom of the print ad ie:
Body Copy Line 1
Body Copy Line 2
This assumes that the reader will make the connection, the site is ranked for its domain name, and the user wont accidentally click the wrong link on the SERP.
Would be interested in thoughts and suggestions.
