Posting jobs on Google for Jobs is possible if you structure the underlying HTML of your job postings so they can be indexed by Google for Jobs. Alternatively, you can post your jobs on a 3rd party job posting site that Google for Jobs already indexes if you are not able to make the modifications to your own site.
How to Post your Jobs on Google Directly:
1. You'll need a website.
You won't be able to directly send your jobs to Google search results if you don't have a website, but if you don't you may be able to post with a 3rd party site that does post to Google, although many job boards require companies to have a site also.
What is Google for Jobs?
Google for Jobs uses artificial intelligence, machine learning, and integrations with job boards to make it possible for jobs to be seen in Google search results, and to be found more easily, despite the variety of titles a job may have. It has potential to bring a lot more visibility to job posts.
2. Publish your job postings on the website.
Seems pretty straightforward. You'll want a careers page on your site that lists all your current job postings.
3. Add job listing structured data to your jobs page.
This might sound scary if you're not a technical person. Adding structured data to the job postings tells Google that it's a job posting and labels the essential info. If you can't do this and don't want to go 3rd party, it should be easy to find a freelancer who can.
4. Use sitemaps to let Google know when you've added and removed jobs.
If you want people to apply to jobs you've just posted, or don't want them to apply to jobs you've taken down, use sitemaps to quickly tell Google what's going on. Again, you'll need someone technical to set this up and submit them.
5. Track results in Google Search Console.
You'll be able to see impressions and clicks in search console, to see how well Google for Jobs is working for you, and make sure it's running correctly.
Post a Job for Free on Google:
To post a job for free on Google, you just need to configure your jobs page correctly so that it integrates with Google for Jobs, or use a 3rd party service to do it for you.
Google Job Posting FAQs:
Can any business post a job on Google for free?
Yes, as of now it appears any business can use this service if the jobs are posted in English. It does not appear that the Google job search engine has been rolled out to non-English-speaking countries yet.
Is there a Google job posting site?
Not really. Rather than create a separate Google for jobs website, or Google job board, Google job listings show up in organic search results. So if you search for something like "Engineer jobs near me" on Google's homepage, you'd see Google job postings that match that search among the results.
How long does it take for my Google job listing to show up?
Assuming you have everything setup correctly, it shouldn't take too long - you just have to wait for Google to index your site. This can sometimes take a few days.
