How to audit ATS job-board coverage for a target list

Start by defining what coverage means

"We support Workday" and "we found every relevant opening" are not equivalent claims. A target-list audit is more useful when it reports several smaller facts instead of collapsing them into one percentage.

1. URL validity: Is the submitted value a public HTTP or HTTPS URL?
2. Host recognition: Does the URL match a public ATS pattern the workflow understands?
3. Board resolution: Can the employer-specific board identifier be derived or confirmed?
4. Job retrieval: Does the current public endpoint return a complete response?
5. Role relevance: Are any current roles useful for this specific job search or staffing market?

Keep the denominator visible. If 40 URLs are valid and 26 match recognized ATS hosts, the recognized-host rate is 26 divided by 40. Invalid entries should be reported, but they should not quietly change that denominator.

A five-step target-list audit

1. Collect source URLs, not search-result links

Use the employer's public career site or job-board URL. Avoid login pages, applicant portals, search-engine result URLs, and links copied from private systems.

2. Normalize and deduplicate the list

Remove exact duplicates and preserve the original employer association. A clean input list prevents repeated boards from inflating the apparent coverage rate.

3. Classify the host

BD Engine's browser-based audit recognizes public patterns for Greenhouse, Lever, Ashby, SmartRecruiters, Workday, BambooHR, Workable, Jobvite, Recruitee, Personio, and Rippling. An ordinary company careers page can still be valid even when its ATS cannot be identified from the URL alone.

4. Test retrieval separately

A recognized host can still have a renamed board, custom configuration, transient challenge, or changed endpoint. Treat retrieval as a later operational check, not something host recognition has already proven.

5. Review current roles against the target

Coverage becomes useful only when the returned roles match the user's role family, location, seniority, and recency requirements. A large job board with no relevant role is not a qualified target.

How to read the result

Recognition is not retrieval. A recognized host identifies a likely integration path. It does not confirm that the employer-specific board currently resolves or returns every page successfully.

• Recognized: The host matches a supported public ATS pattern. This is a compatibility signal.
• Needs discovery: The URL is public, but the ATS or employer-specific board cannot be confirmed from the submitted URL.
• Invalid: The value is not a usable public career-site URL and should be corrected or removed.

Do not present the recognized rate as a guarantee of complete employer coverage, role count, role freshness, or scraping reliability. Those are separate measurements with different failure modes.
