HR professionals have a hard enough time managing their staff to operate at peak performance. However, finding the right people to fill an open position from the start can help alleviate a lot of trouble later on down the line.

One of the key ways to attract the right talent is writing an effective job description. It needs to explain enough about the job that you get the right applicants, but also needs to make the position and your company sound alluring enough to be sure you get any applicants at all. On that note, EBI looked at 15 science-backed tips to answer the question how to write job descriptions – here they are.

On job titles

  • Keep titles 50-60 characters long
    Job titles with 50-60 characters out-performed other by 30% – 40%.
  • Be specific with your titles
    Including the term “cashier” outperformed a title with the less-specific “crew member” by over 60%.
  • Be specific to your industry
    Including the term “CNA” outperformed “Certified Nursing Assistant” by almost 40%.

On overall layout

  • Put important information first
    Eye-tracking shows the readers usually skip the bottom section of the description completely.
  • Don’t forget about the company description
    When reading a job description, users spent almost as much time reading the company description as they did the job description. In fact, they spend 25.9s on reading the job description, 23s on company description, and 14.6s on job requirements.
  • Make it scannable
    Eye-tracking tests have shown that readers typically skim the job description portion.
  • Include salary information
    Putting salary information near the top of the job posting double the amount of applicants.
  • Consider a salary range
    Including a salary range can increase your applicants by 50%.
  • Optimise for mobile
    53% of 18 to 29 year olds use a smartphone to job search.
