If you own a blog and want to add job listings to it there are a number of plugins to do that. But most of those only backfill from Indeed. But no more. Pete Metz, owner of SkiptheDrive, has changed that. He developed a WordPress plugin that lets you search and browse listings from Jobs2Careers, now the 2nd largest aggregator behind Indeed.
I have installed it to display recruiting/HR jobs on my site RecruitingHeadlines.com. View it here.
There are 2 steps required to set it up. First you have to have a publisher account from J2C and create a new feed for yourself from there dashboard. Once you have that you copy the user id and password from with that url and insert into the settings of the app. Just search for Jobs2Careers in the plugin store to find and install the app. One cool feature is that you can limit the backfill to a certain location if you have a local job board. Get the plugin here.
NOTE: you cant post jobs, the plugin is only search/browse so its probably a better option for blog owners who just want a little extra backfill revenue. There is no cost for the plugin.
