One SEO professional was curious about multiple job posting Schema markup. In a hangout, they asked John regarding this Schema markup.
Their question was about multiple job postings in different domains. With job posting structured data, they were under the impression that, because of the guidelines, it’s not a good idea to use this Schema more than once on the same page.
As an international job provider, they have a corporate structure with several brand websites, but also multiple subdomains for one brand. The question is: is it a problem if the same job postings are posted on the same root domain, but different subdomains with structured data from the job posting?
For example: say one of the same jobs is on jobs.domain, and the other one on www.domain. It’s the same job, but maybe different styling, and perhaps with the same structured data on both subdomains being posted.
Is there a problem with that?
John explained that while he did not know all details regarding job postings, he would assume that’s perfectly fine, because it’s common to have the same job posted on different websites.
These different websites could have structured data on them also.
From this perspective, just having it hosted at different times on the same site, or in different subdomains, that should be perfectly fine also.
He doesn’t know the details of all of the guidelines surrounding Job postings, though. So it may be that there’s some obscure method that you should only list once on each site.
But, John would be surprised if this were a problem.
