Here's a cool idea in which your company's website can earn inbound links by posting current employment opportunities.
Search Google for "post job opportunities" and you'll find an unlimited amount of sources seeking job opportunities. Many of the sites are free, while others charge a small fee.
Target top-ranked sites and those specific to your industry.
Here, you can post any current company job openings with a link pointing back to your website. If possible, include the link to your company's careers or job opportunity page.
