Employer branding measurement mistakes in reporting and how to fix them

What to take away

What changedmeasurement questions now arrive with compliance and procurement follow-ups attached. Expect to justify the applicant data behind a metric and the cost per application it produced.
Candidate data rules are now part of measurement. Teams must show a lawful basis for the applicant records they keep, and the ICO publishes the guidance they work from.
A written standard beats a clever dashboard. Name the baseline, the owner and the review date for every figure you publish.
Inclusion criteria for this list are England-based in-house teams, agency-side reporting and roles advertised in the UK. It does not rank suppliers or recommend tools.

Mistake one: counting activity instead of hiring outcomes

Reach figures with no hiring denominator

Impressions, video views and careers page sessions are easy to pull and hard to defend. On their own they say nothing about whether the right people applied. Pair every reach figure with a hiring denominator, such as applications per vacancy or interviews per shortlist. A careers page attracting 10,000 sessions and no engineering applicants is a warning, not a win.

Reach vs hiring outcomes

Reach-only

Impressions: Reported alone
Careers page: 10,000 sessions
Applications: 300, no offer
Budget: One blended line

Outcome-paired

Impressions: With applications per vacancy
Careers page: Engineering applicants tracked
Applications: Stage-by-stage conversion
Budget: Separate media, tool, agency

Volume alone also hides quality. A vacancy that draws 300 applications but no offer at interview stage has a sourcing problem, not a reach problem. Report stage-by-stage conversion so the weak link appears before the next campaign budget is approved.

Tool and media costs blurred into one line

Sponsorship, job board spend and software subscriptions often land in a single budget line. That hides which activity produced which applicant. Keep separate cost codes for media, tools and agency time, then report cost per application against each. Procurement work gets easier too: the comparison of LinkedIn hiring products sets out what Jobs, Recruiter and Recruiter Lite include.

Agree the cost codes before the first invoice arrives. Reallocating spend after the quarter closes rarely survives a finance review.

Mistake two: breaking the trail between brand work and candidates

Applicant tracking data that never joins up

Campaign tracking usually sits in a marketing tool while applications sit in an applicant tracking system. Without a shared candidate identifier, you cannot say which content preceded an application. Agree a short set of source tags with the recruitment team and apply them consistently. The employer branding measurement and reporting guide explains how those tags feed a wider reporting cycle.

Candidate data kept without a lawful basis

Every applicant record needs a lawful basis, a retention period and a route to deletion. Retention is the usual loose end: data sits in a spreadsheet long after the campaign closes.

The ICO's UK GDPR guidance and resources sets out the principles that apply when you process candidate data, including storage limitation. A measurement plan should name who deletes what, and when.

Set the retention clock yourself rather than accepting a default. Choose a period short enough to defend and long enough to answer a candidate query.

Retention duties do not stop at the campaign. Older legislation still shapes public sector practice: the Local Government Act 2003 remains on the statute book, and teams that skip record-keeping duties inherit avoidable risk.

Mistake three: publishing numbers without a written standard

A written standard stops a report changing shape between authors. The table below shows the shift most teams make once the rules are on paper.

Before

Reach: Impressions reported alone
Cost: One blended budget line
Candidate data: Records kept indefinitely
Review: Dashboard opened when asked

After

Reach: Impressions paired with applications per vacancy
Cost: Separate media, tool and agency codes
Candidate data: Named retention period and deletion owner
Review: Monthly review with a named owner

No baseline before the campaign starts

A metric without a starting point cannot show change. Capture the previous quarter's application volume, time to hire and offer acceptance rate before anything launches, then report the difference rather than the raw number. Label illustrative figures: a team spending £400 a month on sponsored posts should still record what that spend produced.

Seasonality distorts comparisons. Graduate intakes and January hiring peaks will flatter or flatten a result unless the baseline comes from the same period a year earlier.

A dashboard with no named owner

A reporting dashboard in England needs a person attached to it, not just a login. Someone must refresh the data, check the source tags and close gaps before a leadership meeting. Without an owner, a dashboard quietly rots.

Name a deputy as well, so annual leave does not leave a leadership pack half-built.

Common questions

How often should employer branding metrics be reviewed?

Monthly for live campaigns, quarterly for brand measures. Write the rhythm down so a review does not depend on someone remembering.

What belongs on a measurement mistakes checklist?

At least four checks: a hiring denominator, a separate cost code, a candidate retention rule and a named owner. Add a baseline date for anything you compare.

Does this list apply across the UK?

Recruitment law and reporting duties differ by nation. Check the rule that applies where the role is advertised and where the candidate lives.
