If you've already created a job ad, you can publish or republish it to the major job aggregators from the Edit Job wizard.
Be careful not to repost/republish your your jobs to the free aggregators too frequently. Aggregators may blacklist your jobs or bury them farther down the results if you republish jobs before the listing expires.
To republish an ad to the free aggregators, just edit the ad.
Jobs submitted through SmartRecruiters to the free job aggregators usually go live on the aggregators' feeds within 24 to 48 hours.
