One of the questions I often get is…how much should I charge employers to post a job?
Well the answer should depend on your existing competition. If you are a new job board entering a market with other sites I suggest undercutting them in price in order to gain market share.
But at a minimum I would say a job post should be around $100 for 30 days
Anything less will be hard to make money with. You can only charge a lot if you have a lot of traffic, so undercutting your competitors is one of the few ways you can get an employer to try you.
