Advertising a job on the internet and in print relies on people positively searching for a job to find your vacancy. If you use radio advertising, then all the listenership will hear the advert, whether they are seeking work or not.

National radio advertising is usually only within the realms of larger companies. Small and medium sized firms should investigate their local radio stations, whether BBC or independent. Many will have a "jobspot" where you can inform the listeners of vacancies for no cost. Some of these, though, only draw their information from the local JobCentre. If you have a major recruitment drive in a particular area, you could consider paying for on-air advertisining space. You could write some of the cost of the recruitment advertising to your general advertising budget by making the commercial fulfill a general publicity need as well.
