Proximity is not exact

The methodology looks at completely separate ads and through several innovative technologies, looks to see if their Employer Brandings, Job titles, Req numbers, etc… are in fact related enough to be considered different ads for the same job position.


Ad 1

Company: HCA

Title: RN – full time

Location: New York, NY

Ad 2

Company: HCA Healthcare Corporation

Title: Registered Nurse - FT

Location: NY City

(Both ads are different and represent dollars spent, however they are viewed as the same job)

To the media client, this can result in revenue dollars and market share for ads sold not represented properly as 2 Ads ( in Ad view) could be displayed as 1 Job (in job view). This can also artificially reduce the total volume of revenue generating ads and market share in job view.

Each location = 1 job

Also, under the methodology, every city given in an ad will be counted as one job in the jobs view.


Title: Registered Nurse

Location: New York, NY; Chicago, IL; Boston, MA

This example on 1 Ad (in ad view) would be viewed as 3 jobs when in jobs view. In this case, a single ad sold could be counted multiple times, creating artificial revenue and ad share.


Ads: job postings including duplicates. Trends tab: ads. Counts tab: +'duplicates'.

Jobs: unduplicated job postings. As shown in all tabs. Trends tab: jobs.

New Ads

All ads with a first seen date within the defined timeframe; the only unduplication is the url/crc check to ensure we aren’t counting the same pages twice. Not ideal when wanting to view how many ads are on a site as it does not represent the entire site; only ads added from a certain date.

New Jobs

Using proximity unduplication, and geographic separation, this view is an interpretation of how many open jobs are being advertised; not how many unique ads there are. 

In some cases the jobs view will be higher than the ads view.

Available Ads

“Available ads” shows how many ads were on a site throughout a timeframe (week, month). The new system now uses the exact dates the ads were online to calculate when they were available instead of the previous 30-day standard; making this the ideal view to see how many ads were online in a specific range.

When analyzing metrics for ad share, this is the purest representation of how many ads were seen on a site during the period.

Available Jobs

Using Proximity unduplication, geographical separation and time-to-live of ads between sites, available jobs will show how many jobs were “open” during a timeframe, regardless of age AND site. The availability of the job will be a composite of all ads founds across all sites through time. This will not portray ad volume as one might expect.
