Writing a good job description for a job posting would seem fairly easy to most however having read hundreds, if not thousands of them, perhaps it's more difficult than realized. A lot can be said for a well-formatted, grammatically correct job description. A lot of them however read like product advertisements rather than an invitation to join a great staff and work towards a common purpose.
The most important thing the HR manager, recruiter, manager or whomever is writing the job description can do is craft a job description that is both informative and inviting. In other words, put yourself in the job seeker's shoes and write the description that would make you pursue the job. Avoid job descriptions with long lists of bullet points or educational and experience requirements unless its truly necessary at this stage in the recruiting process. The more requirements or restrictions (read: hurdles), the fewer applications you will likely receive. Try to come up with a reasonable trade-off. Most of the more specific qualifications can generally be derived from one's resume or during a face to face job interview.
Also avoid distasteful sounding questions like "Want to earn unlimited income?" Questions like that will quite likely yield zero applicants.

An effective job description should have three paragraphs:
- Who we are, what we do and where we do it.
- What services we need performed by the new hire.
- Brief salary, benefits and/or perks offered.
Keep it simple and straightforward and you can't go wrong.
