PostJobFree.com vs Paid Job Boards

Here's the story explaining why it's better to post your jobs on PostJobFree.com and on PostJobFree.com only.

Today a recruiter asked me: why her PostJobFree job openings are not available on Indeed.com?

Quick investigation showed that:
1) She posted the same job openings on couple of paid job boards and only then posted on PostJobFree.com.
2) Indeed.com considered these job openings duplicates, so later posts (made through PostJobFree) were hidden as duplicates in Indeed.com search results.
3) Her posts on paid job boards expired already, so when job seeker opens link on Indeed.com -- he sees: "Sorry, this job is no longer available. It may have been filled by the employer. Please try another search below.".
That's quite disappointing, considering that job opening is still open.

Conclusion:
- Posting on paid job boards may hurt you, if you don't have money to pay for running your job ad long enough.
- You would be better off if you just post your job on www.postjobfree.com and stay away from paid job boards.
