Total Job Postings is the total and unduplicated number of online job advertisements listed by different companies on career sites and job boards. These postings have been paid for (“syndicated”) and are not free job postings.
Deduplication is the process of identifying duplicate job postings and only counting one of the duplicates. The total posting count is the count of postings before the deduplication process. The unique posting count is the count of postings after the deduplication process. For example, if a user runs a report that returns 12 total job postings and 2 unique postings, this means that the 12 postings contained 10 duplicates and only 2 unique job advertisements.
