Available Data
Here's what you can extract from G2 using AlterLab:
Business Use Cases
How businesses use G2 data to make better decisions:
- Bulk G2 review data collection for competitive analysis
- Automated review extraction pipeline for product intelligence
- G2 rating monitoring against competitors
- Feature feedback extraction for product roadmap research
How It Works
Provide G2 product profile URLs to scrape
Submit the G2 review page URLs for the software products you want to extract data from (e.g., g2.com/products/hubspot/reviews). G2 category pages list all competing products in a software vertical, making it straightforward to build a list of profiles to collect.
AlterLab extracts reviews and ratings from G2
G2 loads review content and feature scores dynamically via JavaScript. AlterLab renders the full product page and extracts the complete review dataset — overall rating, individual review text, reviewer metadata, and feature satisfaction scores — returning it as structured JSON.
Get structured G2 review data for analysis
Receive overall G2 rating, review count, category ranking, individual review pros and cons with reviewer company size and industry, feature-level satisfaction scores, and Momentum Grid positioning — all structured for competitive dashboards, sentiment pipelines, or feature prioritization research.
Key Insight
When extracting G2 review data, the reviewer metadata is as valuable as the review text itself. G2 captures reviewer company size (SMB, Mid-Market, Enterprise), industry, and job role — data not available on consumer review platforms. Segmenting extracted reviews by company size reveals whether a competitor scores differently with enterprise buyers versus SMBs, a distinction that aggregate star ratings obscure entirely.
Data Freshness
G2 ratings update continuously as new reviews are submitted. For active competitive monitoring, run your G2 review extraction monthly to track meaningful rating movements. G2's quarterly Grid Reports update on a fixed schedule — scheduling collection before and after report releases captures ranking changes that influence buying decisions.
