Frequently Asked Questions
Can I monitor multiple competitors at once?
Yes. AlterLab processes concurrent requests efficiently, so you can monitor dozens of competitor sites, product catalogs, and review platforms in parallel without managing infrastructure.
How do I extract reviews and ratings?
Use the structured extraction feature to specify the data points you need (ratings, review text, dates). The API handles JavaScript rendering to capture dynamically loaded review content.
Responsible Use
AlterLab is designed for extracting publicly available data. Always review the terms of service for any website you access, respect robots.txt directives, and ensure your use case complies with applicable laws in your jurisdiction.
