Hiring velocity
Hiring velocity is the rate of new vacancies appearing over time for a company, team, or role family.
For agencies, it helps show changing demand. Not just how many jobs are open, but whether new roles are appearing faster or slower than before.
What hiring velocity means
Hiring velocity answers one useful question:
- How quickly is a company adding new roles?
It is usually measured as new job postings per unit of time: per day, week, or month. The count comes from vacancies you can observe on public sources such as career pages and job boards.
Velocity vs. absolute volume
Agencies often blend two different signals:
- Job volume (stock): how many roles are open right now.
- Hiring velocity (flow): how many new roles are being added over a period.
They tell you different things.
A company can have high volume and low velocity: plenty of old vacancies still sitting there. Another can have low volume and high velocity: roles opening and closing quickly.
How to measure hiring velocity from observed vacancies
The simplest version is a count of newly detected roles in a set period.
Common approaches:
-
New postings per week
Count roles first seen during each week. -
Rolling averages
Smooth noisy weeks with a rolling window, such as a 4-week rolling average. -
Acceleration (change in velocity)
Check whether the rate is rising or falling.- Example: 5 new roles/week last month → 12 new roles/week this month = acceleration.
-
Baseline comparisons
Velocity needs a baseline before it means much:- Company baseline: compared with that company’s usual rate.
- Market baseline: compared with peers in the same sector, size band, or geography.
Why role/category mix matters
A spike in velocity is not always useful to your desk.
Break it down by:
- Function: engineering, sales, operations, finance
- Seniority: IC vs. leadership
- Location: single-site hiring vs. multi-location rollout
- Contract type: perm vs. contract, if you can observe it
A run of customer support vacancies does not tell a data engineering recruiter much. The category matters as much as the headline count.
Interpreting hiring velocity for agency prioritisation
Velocity is useful when it helps you decide where to spend time.
Good questions:
- Which accounts are changing fastest? New demand may be appearing.
- Which markets are heating up? More new roles are showing up.
- Which teams are scaling? Several new roles may be appearing in one function.
Practical agency uses:
- Account tiering: put companies with rising velocity in your niche higher on the list.
- Timing outreach: move when the rate changes, not after the vacancy list is old news.
- Focus by category: point BD at the functions with the highest new-role rate.
Comparing periods without fooling yourself
Keep the comparison clean:
- Compare like-for-like windows, such as last 4 weeks vs. prior 4 weeks.
- Allow for seasonality. Some employers hire in cycles.
- Use consistent sources: career page vs. job board vs. both.
- Watch for duplicate counting, especially when the same job appears on several boards.
Common false signals (and how to sanity-check)
Observed posting velocity is noisy. A spike can come from:
- Reposts / refreshes: the same role published again
- Evergreen pipelines: always-on ads that do not reflect a new headcount decision
- Template multiplication: one job posted in 20 locations
- ATS or career site changes: a redesign making old roles look new
- Internal backfills: replacement hiring raising velocity without growth
Useful checks:
- Look for unique role IDs where they exist, not just titles.
- Track whether roles are net-new or reappearing.
- Separate multi-location clones from distinct openings.
- Review a sample of the “new roles” and check they are actually new.
What hiring velocity does not tell you
Hiring velocity is an observed vacancy signal. It is not a full view of hiring outcomes.
It does not reliably tell you:
- How many offers were made
- How many hires were completed
- Whether headcount is growing, rather than replacing leavers
- Whether the company will use agencies for those roles
Common misconception: “More postings = headcount growth”
Hiring velocity is observed job-posting activity, not confirmed headcount growth.
A company can post quickly and still stay flat because of backfills, churn, or evergreen ads. Use velocity as a prioritisation signal. Then check the role detail, timing, and context: press updates, team expansion clues, or repeated patterns in one function.

FAQ
What’s a simple way to calculate hiring velocity?
Start with:
- Hiring velocity = count of new roles first seen in a period / length of period
Example: 24 new roles first seen over 4 weeks → 6 new roles/week.
If the weekly count jumps around, use a rolling average such as a 4-week rolling view.
How is hiring velocity different from hiring volume?
Volume is the number of roles open at a point in time.
Velocity is how quickly new roles are being added.
Agencies care about velocity because it can show a shift in demand before a static open-role list makes it obvious.
What time window should we use—weekly or monthly?
Use the shortest window that is still stable for your niche:
- Weekly: useful for fast-moving sectors or high-volume hiring.
- Monthly / 4-week windows: better when hiring is patchy and you want fewer false alarms.
Many teams track weekly counts, then review the trend on a rolling 4-week basis.
How do you compare velocity across companies of different sizes?
Raw velocity tends to favour large employers. A few ways to keep it fair:
- Compare each company with its own baseline. Is it speeding up or slowing down?
- Segment by size band or peer set.
- Compare within a role family, such as data roles only, rather than the whole company.
What causes false spikes in hiring velocity?
Common causes include:
- Reposted jobs that look new
- Evergreen roles that never close
- One role duplicated across many locations
- Career site / ATS changes that refresh timestamps or URLs
If you use velocity for BD triggers, sample the “new” roles before acting on the spike.
How should agencies use hiring velocity in business development?
Use it to prioritise and time outreach. Do not treat it as proof on its own.
- Prioritise accounts with rising velocity in your niche.
- Aim outreach at the function that is accelerating.
- Combine velocity with context: role mix, locations, and press or news updates before you spend heavy BD time.
Can hiring velocity tell us whether a company will use agencies?
No. A higher rate of postings does not reliably indicate agency use.
Treat velocity as a signal that something is changing in hiring activity. Then qualify the opportunity the way you normally would.
