This guide outlines the lead generation metrics and KPIs that give you real insight, not vanity metrics. You can use them to uncover hidden gaps, optimize handoffs, and drive smarter, faster decisions that tie directly to commercial outcomes.
Why Do We Need So Many Lead Gen Metrics?
To improve marketing’s revenue impact, you need metrics that go beyond volume. These lead generation KPIs and metrics will help you isolate where to optimize lead quality, conversion velocity, and channel ROI.
What Are The Best Lead Gen KPIs and Metrics?
Every business is different, and so are the things you report on.
There’s no one-size-fits-all when it comes to reviewing how your B2B lead generation is doing.
But if you’re looking to expand your reporting data, you need to choose metrics that matter. Start by thinking about your goal and thinking about how to reflect that in your web analytics tools.
This list of the top 18 metrics and KPIs for measuring lead generation should help inspire your next report.
Pipeline Contribution KPIs
When you report on lead gen to the wider business, it’s helpful to frame the numbers in a way that helps demonstrate how your lead gen strategies are contributing to the sales pipeline.
Marketing Qualified Leads (MQLs)
Perhaps your most-reported KPI will be the number of Marketing Qualified Leads you’ve earned.
This term describes the leads that meet specific engagement and demographic criteria that indicates they’re more likely to convert.
Knowing the number of MQLs will help determine whether your marketing efforts are generating interest from the right audiences. It can also help you know more about your lead gen efforts, including:
- How many leads are progressing beyond top-of-funnel engagement.
- Which campaigns or channels produce leads that match your ICP.
- Where there could be gaps in your funnel and missed opportunities.
- What marketing’s contribution to the sales pipeline is.
Once you understand your MQL benchmark, you can refine targeting, scoring rules, and lead handoff processes to ensure sales receives the right leads.
But MQL volume alone can be meaningless. What matters is whether your MQLs match your ICP, convert to SQLs, and represent real buying intent.
Sales Qualified Leads (SQLs)
Similarly, SQLs are leads that have been vetted by sales and are deemed ready for direct follow-up. It’s an important KPI for lead generation because it acts as a crucial indicator of the alignment between marketing and sales—and tells you how many of your MQLs are ready to buy.
When you measure the number of SQLs, you’ll learn:
- How many MQLs that are accepted by sales.
- Which channels or campaigns consistently drive sales-ready leads.
- If there’s any disconnect between marketing’s lead scoring and sales’ expectations.
- What your pipeline forecast is, based on your current lead quality.
A weak or inconsistent SQL volume can indicate poor MQL quality or friction in your follow-up activities. If you see your SQL acceptance rate drop, it’s a sign you need to revisit your targeting, nurture strategy or sales training.
Lead-to-Customer Conversion Rate
This metric ties your lead generation funnel together by giving an overall view of how many leads eventually become customers.
This lead gen metric will give extra insight into:
- Which campaigns lead to real business outcomes.
- If you have weaknesses in nurturing, sales follow-up, or qualification.
- Which lead sources to prioritize because they drive the most revenue.
- Your ROI per channel or campaign, which supports marketing budgeting.
A low lead-to-customer rate often means leads are converting too early, or your nurture is ineffective. If you’re seeing issues with this metric, you may want to segment the data by source and campaign to identify the most profitable (and under-performing) acquisition paths.
Return on Investment (ROI)
ROI measures the financial return from your marketing and lead generation activities. It connects marketing outcomes to business impact, and it’s probably one of the first metrics you turn to for any marketing review.
When it comes to lead generation, knowing your ROI will help you understand:
- Which campaigns generate the highest revenue.
- Which channels, campaigns and tactics are the most profitable—and where you should plan to invest more in the future
- How to justify your expenditure within the business and build evidence to support requests for increased budgets.
Don’t just report your top-line ROI. To get a proper view of performance, you need to segment it. Make sure you know your ROI by content type, campaign, channel, and beyond.
Channel & Cost Efficiency KPIs
Ultimately, the reason we work so hard to generate leads is to improve revenue. It’s an area that CMOs are increasingly taking responsibility for, so these revenue metrics should also be considered when you’re reporting on lead gen.
Cost Per Lead (CPL)
Your cost per lead measures how much you spend on a lead, on average, and is essential for understanding the efficiency of your lead generation efforts.
You CPL can tell you:
- Which channels are high- or low-performing based on acquisition cost.
- What your ROI is for specific campaigns or platforms.
- Whether your lead generation approach is cost-effective.
- If your budgeting decisions by channel or funnel stage are sufficient to reach your targets.
But beware: a low CPL doesn’t necessarily mean your lead generation is working. You need to combine this metric with insight into conversion and pipeline contribution to truly understand which campaigns have the biggest impact.
Cost Per SQL / Cost Per Opportunity
These advanced cost metrics show how much you’re spending to generate high-quality, sales-ready leads.
This KPI acts as a truth serum for your budget efficiency, as your CPL is only valuable if it leads to actual opportunities and SQLs.
By reviewing your cost per SQL/opportunity, you can learn:
- Which high-quality lead sources are worth scaling
- Where you might be over-spending on low-intent acquisition.
Leads Per Channel
When you measure leads per channel, you’re tracking how many leads each marketing channel generates. If you can establish a benchmark, you’ll be able to ensure your most valuable channels keep delivering a steady stream of leads.
Leads per channel also gives an insight into:
- Which channels deliver the highest lead volume.
- Which channels are underperforming sources and need re-evaluation.
- What your monthly targets should be for each channel, based on past success.
- Where your ICP prefers to engage.
Make sure you segment your leads per channel by funnel stage and ICP fit to get a sense of how you’re performing and adjust your budget where you need to.
Click Through Rate (CTR)
Your click through rate measures how often people click on a call-to-action relative to how many saw it. It’s essential for evaluating how compelling your messages are across digital channels, from your own website copy to paid advertising and email content.
Your lead gen CTR can help you understand:
- Which messages get the highest click through rate and resonate with your audience.
- Which messages under-perform and might need to be reconsidered.
- If there’s any difference in CTR between different channels and which ones need to be investigated.
When you know your click through rates, you can establish benchmarks and start to optimize the areas that are under-performing in order to lift lead volume from existing traffic without additional spend.

Funnel Velocity & Responsiveness KPIs
When we generate leads, we want to move them through the funnel as efficiently as possible. These KPIs and metrics will help you understand how effectively you progress leads through the pipeline.
Time to MQL / Time to SQL
When leads move quickly through your funnel, it’s a leading indicator of their intent to buy. You can measure this by looking at your time to MQL/SQL.
When your time to MQL/SQL is shorter, it can suggest your targeting is working or you have strong hooks. But this metric can also help you learn more about:
- Potential delays in nurturing or lead processing.
- How channel or campaign lead velocity compare.
- Which signals suggest readiness for sales engagement.
- Whether you have any scoring or process inefficiencies.
Your goal should be to improve your time to MQL/SQL. But to reach this KPI, you typically need to look at things like automation flows, content sequencing, or follow-up cadence.
Time to Conversion
By measuring your time to conversion, you keep an eye on how long it takes a prospect to move from awareness to key conversion points like inquiry, demo, or closed/won.
Time to conversion tells you:
- Where delays exist in the buyer journey.
- Which campaigns shorten sales cycles.
- Where faster lead follow-up can drive impact.
- What your nurture timing and messaging cadence should look like.
Your goal should be to reduce this KPI, because shorter time to conversion can improve sales efficiency and create a more agile funnel.
Lead Response Time
Lead response time measures how quickly sales or SDRs follow up on a new lead. We know that time kills deals, so fast responses will help boost your conversion odds.
When you keep an eye on this lead gen KPI, you’ll find out more about:
- How your follow-up speed compares to industry norms.
- If there are any delays that could cost you deals.
- What your win rates and lead experience is.
- Where there might be sales process inefficiencies.
If your goal is to improve your lead response time, you may want to look at how automation or better routing can speed this up and lift conversion rates.
Database Health & Lead Lifecycle KPIs
These lead generation metrics and KPIs will help you review the strength, efficiency and long-term value of your lead database. This kind of insight empowers you to reduce waste, revive your pipeline and extend your campaign ROI.
Lead Quality Score
We know that lead generation isn’t about quantity, so reporting on your lead quality score is a reliable way to measure improvements in this area. Your lead quality score evaluates how closely a lead matches your ideal customer profile based on engagement and firmographic data.
When you monitor your lead quality score, you can understand more about:
- Where your high-intent, high-fit leads come from.
- Where to guide SDR focus and outbound prioritization.
- Whether your scoring models or criteria are effective
It’s worth investing time into this metric because refining your scoring model ensures resources are spent on the most promising opportunities.
Lead Re-engagement Rate
This lead generation metric shows how many dormant leads return to active status through campaigns or outbound efforts. It’s a good way to measure how many leads you’ve won over through reactivation campaigns.
Looking at lead re-engagement rates can also help you learn about:
- The health of your database and lifecycle strategy.
- Which channels or messages reignite interest.
- How to adjust your nurture sequences and win-back planning.
When you prioritize improving your lead re-engagement rate, you maximize your lead database value, reduce your reliance on net-new leads and minimize the sunk cost of missed opportunities.
Email Capture Rate
First-party data is more valuable than ever and measuring how many email addresses you’re adding to your prospecting list is a good metric to support this strategy. Your email capture rate tracks what percentage of anonymous visitors convert into known leads through form fills or gated content.
By keeping an eye on your email capture rate, you also get visibility of:
- How well your content or CTA captures interest.
- What your funnel entry performance by page or channel looks like.
- Where there might be leaks in website or landing page experience.
- How well your lead magnets perform.
When you set a KPI that’s focused on improving your email capture rate, you’ll inevitably expand your addressable lead pool and boost nurture potential.
Conversion Rate
One of the most essential lead generation metrics is conversion rate. This will tell you how many people have completed a desired action and progressed to the next stage of your funnel.
Your lead conversion rate can tell you things like:
- What percentage of website visitors clicked on your ‘book a demo’ button.
- Which campaigns generate the highest-converting leads, so you can consider which ones to repeat or scale.
- Which campaigns or channels generate low-converting leads and might need to be paused.
- How many people respond to your prospecting messages on LinkedIn.
Once you understand your conversion rate, you can estimate how many people you need to reach in order to generate your targeted number of leads—and explore conversion rate optimization strategies to make sure you’re capturing as many potential leads as possible.
