Lightcast Analyst product suite utilized two different measures to track overall job postings trends, more about this can be read here
As of 8th October Lightcast will be improving the infrastructure behind job postings expiry as described here
This will result in:
A dip in top line active postings trend line starting in October, we estimate a 15% change
A better view of the demand in the month
Fewer expired links appearing within sample postings
Customers are advised to use Newly Posted to give a stable/better view of the behavior of the market in a given month and over time.
Customers seeking open demand in the month can continue to use Active postings.
