In a hangout John Mueller did on 09/03/2021, a webmaster was curious regarding manual actions and job posting schema markup.
The webmaster was under the impression that they had received a manual action from Google based on the job posting schema they had included on a particular page.
John explained that manual actions usually target larger patterns than just code on a single page.
If the webmaster had received a manual action, it is likely that the issue is significantly more widespread than just job posting schema on a job page.
He also said that sometimes they can get the manual actions wrong, but that the webmaster should definitely make sure and check whether or not there is anything amiss with things happening across the entire website.
John explained that when a manual action like this occurs, this means that you should work on improving your processes so this issue does not happen again in the future.
