Glassdoor Brand Monitoring API
Track your company's (or a competitor's) Glassdoor rating, review sentiment, and CEO approval rating over time — an employer-brand monitoring use case distinct from consumer-brand social listening.
How the Glassdoor Brand Monitoring API Workflow Works
Unlike consumer brand monitoring (tracking social media mentions), Glassdoor brand monitoring focuses on employer-reputation signals: overall rating trend, review volume, CEO approval percentage, and recurring themes in review text (pros/cons sections). Scrape a company's Glassdoor profile page on a recurring schedule — weekly is typical, since ratings move slowly — and track overall_rating and review_count deltas. For competitive benchmarking, monitor several companies in the same industry side by side to contextualize whether a rating shift is company-specific or an industry-wide trend.
Recommended Tier & Cost
Company profile pages render rating breakdowns and review summaries via client-side JavaScript, matching the same rendering requirement as job listing pages on Glassdoor.

How often should I check a company's Glassdoor rating?
Weekly is typical — overall ratings move slowly since they're an aggregate of all historical reviews, so higher-frequency polling rarely surfaces new signal for this specific metric.
Can I extract the rating breakdown by category (culture, compensation, etc.)?
Yes — Glassdoor's company profile pages break the overall rating into sub-categories like culture & values, work-life balance, and compensation, all of which are included in the structured response.
Can I benchmark my company against competitors on Glassdoor?
Yes — scrape each competitor's Glassdoor profile the same way and compare overall_rating, ceo_approval_pct, and category breakdowns side by side to contextualize your own standing within the industry.
