The unique posting count is the count of job postings after the deduplication process has taken place. The total
posting count is the count of postings before deduplication. For example, if a user runs a report that returns
12 total job postings and 2 unique job postings, this means that the 12 postings contained 10 duplicates and only 2 unique job advertisements.
Number reflects unique job postings for the past 12 months.
