An Employer Advertisement Posting is a great addition to add to your Employer Posting. When you purchase an Employer Posting, you can purchase an Employer Advertisement Posting for an additional fee. Employer Advertisement Postings give an employer the ability to not only post on our home website, but also on our social media websites, including Facebook and Twitter. The advantage to an Employer Advertisement Posting is the ability to feature your posting to a larger audience of qualified candidates.
