Data-driven recruiting: 5 metrics you should care about

You already know that social recruiting can supercharge your talent pipeline, but without the right data, it’s easy to feel like you’re flying blind.

Today’s recruiting platforms offer dozens of metrics, dashboards, and reports… which makes it even easier to lose sight of what really moves the needle. More data doesn’t always mean better results! The key to a successful, scalable recruiting strategy is knowing which numbers actually matter—and how to act on them.

Below, we’ll walk through five essential recruiting metrics every talent team should track. Whether you’re fine-tuning your social recruiting data or building a foundation from scratch, these insights will help you make smarter decisions and attract better talent.

1. Engagement rate

Let’s start at the top of the funnel: engagement.

Engagement rate measures how many people react to, comment on, share, or click your post out of everyone who saw it. In other words, it’s a pulse check on how compelling your content really is.

If your engagement is low, it’s unlikely your audience is paying enough attention to click “Apply,” let alone submit an application. Think of engagement as the spark that starts the candidate journey.

To improve this metric, think about the kind of content that makes you stop scrolling. Team shoutouts, behind-the-scenes clips, and quick “day in the life” videos all help candidates imagine what it’s like to work at your company. Branded graphics, quote cards, and simple templates can also help you stay consistent and on-brand, especially when you’re posting at scale.

Need even more engagement? You can also experiment with lighthearted prompts that encourage participation. Questions like “What’s your go-to Monday morning song?” or “Drop the GIF that sums up your week” give candidates a reason to interact—and keep your employer brand top of mind.

2. Click-through rate (CTR)

Once you’ve captured attention, the next step is encouraging action.

Click-through rate (CTR) tracks how many people clicked a call-to-action link (like “See Open Roles” or “Apply Now”) compared to how many saw the post. A strong CTR means your messaging is resonating enough to move someone from social media into your hiring funnel.

If your CTR is low, it could be a sign that your post lacks a clear or compelling CTA, or that your visuals and headlines aren’t strong enough to earn that next step.

To boost CTR, place CTAs directly after something that grabs attention, like a powerful stat or short employee quote. Be specific with your language, too. “Apply now to join our sales team” is more effective than a vague “Learn more.”

Also, keep an eye on platform performance. If LinkedIn posts drive significantly more clicks than Facebook, consider reallocating your budget to prioritize what’s working or testing new messaging on the underperforming channel.

3. Application conversion rate

Clicks are great, but they don’t mean much if candidates abandon the process once they land on your careers page.

Application conversion rate measures the percentage of visitors who actually complete an application after clicking through. According to HireHive, a typical application conversion rate ranges between 7% and 10%, and anything above that is considered strong.

If your numbers fall short of that benchmark, your application process may be introducing too much friction. Are you asking candidates to fill out multiple pages? Are the job descriptions too vague or too long? Are mobile users getting stuck? 

Put yourself through the application flow and see where you get confused or frustrated, and remember that small improvements can go a long way! For example, reducing the number of required fields, adding a “copy from resume” feature, or making the application mobile-friendly can all help lift conversion rates and prevent drop-off.

4. Time to fill

Next, time to fill tracks how many days pass between your first post about an open role and the moment a candidate signs their offer letter.

Optimizing this metric matters for two big reasons: it keeps your best candidates engaged and reduces your overall cost of hiring. A shorter time to fill also prevents top talent from getting snapped up by competitors while your process drags on.

To improve this metric, look for opportunities to streamline your hiring flow. Automating steps like interview scheduling with calendar links or chatbots can shave off days (or even weeks!). 

If certain roles consistently take longer to fill, dig into your pipeline. Are there bottlenecks in sourcing, screening, or interviews? Identifying where candidates drop off—or where your team slows down—can reveal actionable ways to speed things up.

5. Cost per hire

Finally, cost per hire shows how efficient your recruiting strategy really is. This metric calculates the total cost of your social recruiting efforts (ad spend, platform fees, agency costs, etc.) divided by the number of hires made through those channels.

Knowing this number helps you make smarter budget decisions, so you can double down on high-ROI campaigns and cut underperforming ones.

For example, if you find that video ads consistently lead to a lower cost per hire than static image ads, shift more budget toward video. You can also experiment with tactics like day-parting (running ads during peak user hours) to stretch your budget even further.
