How does Emsi Burning Glass collect job posting data?

Emsi Burning Glass Aggregation Process:

Emsi Burning Glass collects data from a comprehensive set of online sources. Emsi Burning Glass identifies websites with employment opportunity related content utilizing spider technology to search those sites for employment opportunities. Currently, Emsi Burning Glass maintains two kinds of spiders, which: 1) continually monitor or scout websites to identify those that include employment opportunities; and 2) continually spider and extract employment opportunity related information from a master list of websites. The use of “scout” spiders enables Emsi Burning Glass to recognize new sites and queue them for addition to our master list. We also encourage our customers to let us know of important local sources for job content so that we can queue these sites for investigation and possible addition. This sophisticated, two-step process enables Emsi Burning Glass to retrieve job listings from a much broader range of sources, including job boards, government agencies, educational institutions, and thousands of employers of all sizes, locations, and industries. It is especially significant that Emsi Burning Glass spiders visit so many private and public employer websites directly providing the better representation of small and mid-sized employers than other solutions that rely heavily on postings sources from job boards and from large employer feeds.
