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. 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 too.
2. Publish your job postings on your 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.
