Glassdoor Dataset API
Company reviews, salary reports, interview experiences, and workplace ratings for employer intelligence.
Available Data
Here's what you can extract from Glassdoor using AlterLab:
Business Use Cases
How businesses use Glassdoor data to make better decisions:
- Employer brand monitoring
- Compensation benchmarking
- Recruitment intelligence
- Company culture analysis
How It Works
Identify the target companies on Glassdoor
Provide Glassdoor company overview or review page URLs for your target companies. Glassdoor company URLs include a stable company ID (e.g., EI_IE1234) that remains consistent — useful for constructing direct links to reviews, salaries, and jobs pages.
AlterLab retrieves publicly visible company data
Glassdoor applies access controls that block standard requests. AlterLab renders company pages using full browser simulation, retrieving all publicly displayed ratings, review summaries, and aggregate salary data without requiring authentication.
Get employer intelligence data ready for analysis
Receive overall company rating, dimension scores (culture, compensation, work-life balance), CEO approval percentage, individual review pros and cons, and salary ranges by role — all structured for HR analytics or competitive benchmarking.
Key Insight
Glassdoor ratings are a lagging indicator of company culture — they reflect past employee experience, not the current state. A rapidly falling rating (downward trend over 6-12 months) is a stronger signal of culture problems than a single low score. Track rating trends over time rather than snapshots for meaningful employer intelligence.
Data Freshness
Company ratings and review counts change as new reviews are submitted. Monthly collection is sufficient for employer brand tracking. Salary data on Glassdoor updates as new submissions come in — quarterly collection gives up-to-date compensation benchmarks.
