Step 1) Gather job & company data
I queried our active job listings and selected the most recent job posting from each of 22,346 companies. Here is the distribution of company sizes:
Size | Company Count
Micro (1–10) | 1,806
Small (11–50) | 2,355
Medium (51–250) | 6,902
Mid-Market (251–1,000) | 4,959
Enterprise (1,001–10,000) | 2,073
Large Enterprise (10,000+) | 253
Unknown | 3,998
Total | 22,346
* Job listing / company data sourced from UnlistedJobs
Step 2) Collect Google search data
Here is the Google search query (as entered): [Job Title] + [Company Name] —and repeated for each job.
* Google SERPs (Search Engine Results Page) were collected using DataForSEO's API.
Step 3) Scrub the data
I only want direct links to job listings, so other search results were excluded.
- No:
https://www.linkedin.com/jobs/hartford-funds-jobs - Yes: https://www.linkedin.com/jobs/view/it-data-engineer-at-hartford-funds-4302815125
Step 4) Skip Applicant Tracking Systems
Lever, Greenhouse, etc. don't have searchable job boards so they were skipped.
Step 5) Results
After querying first-page Google results for 22,346 job postings, here are the top domains:

Step 6) Final thoughts
Roughly two-thirds of all job postings can be found on at least one of the major job boards (LinkedIn, Indeed, ZipRecruiter, or Glassdoor).
More than 1 in 4 jobs are not listed on any job boards.
