Determining when a given person will be receptive to solicitations to leave his or her current employer is like trying to time the stock market. Maintain a list of links to these on your site, but some great information also comes from newsletters not specifically tied to recruiting. Applicants can send you a resume in a second via mouse-click. An autoresponder sends an automated template message to the job seeker even before you have a chance to open the e-mail. You may be entitled to have your jobs listed there free, as well as have access to resumes.
Most companies have no brand recognition with job seekers, especially relocating ones.
Some of the fee-based Internet career services are worth the money. But which ones are best vary, based on the employer's industry, location, job title, and even time of year. Employers and recruiting agencies alike are learning that job applicants rarely respond in sufficient numbers to newspaper ads or even to online job postings on the major Internet career sites. The problem with many of the big Internet job sites is that when you find desirable candidates by searching their resume databases, you're probably the 35th recruiter to contact them. These sites are still relatively unused by recruiters, even though they offer sophisticated search engines attached.
