If your marketing report says “we published 12 posts and grew 23% on LinkedIn,” you don't have metrics: you have activity indicators. What an industrial executive needs is 7 B2B marketing KPIs that translate into euros, on three levels: three basic metrics (qualified leads, website conversion, cost per lead), three funnel metrics (CAC, LTV, and pipeline velocity), and one master metric (marketing ROI / influenced revenue). With them, you stop spending blindly and can justify every euro to the executive team.
In industrial marketing, you don't win by publishing more but by measuring what actually drives business. Most companies are stuck on vanity metrics: visits, followers, posts published. They sound good and are easy to present, but they don't answer the only question that matters: how much revenue does marketing bring in, and what does that result cost me? These are the seven B2B marketing KPIs that do answer it, grouped so you can see what to measure first and what comes next.
The 3 basic B2B marketing KPIs that replace “vanity” metrics
They're the floor, not the ceiling. If you're not clear on them, no marketing strategy will hold up in front of an executive team. They tell you whether you're generating leads and at what cost, which is where any serious budget conversation starts.
Metric 1: Qualified leads per month (MQL and SQL)
A lead isn't just someone who filled out a form. A qualified lead meets three conditions: they fit the customer profile you can serve, they have a real need, and they're at a point in the buying cycle where your involvement makes sense. That's why it pays to separate two types: the MQL (marketing qualified lead), who has shown relevant interest (downloaded a technical case study, requested information about a service, visited strategic pages), and the SQL (sales qualified lead), whom your sales team has already contacted and confirmed as a real opportunity.
In healthy industrial B2B, 20–40% of MQLs typically convert into SQLs and 15–30% of SQLs into sales opportunities. If your marketing department isn't giving you these numbers every month, broken down by channel, you're not measuring: you're guessing.
Metric 2: Website conversion rate
It's the percentage of visitors who become leads, and the metric that most quickly reveals whether your website works as a sales tool or as a digital brochure. Here are reasonable benchmarks for industrial B2B:
| Website status | Website → lead conversion | Reading |
|---|---|---|
| Standard website, not optimized | 1% – 3% | Clear room for improvement |
| Optimized website | 3% – 7% | A real sales asset |
| Website with dedicated landing pages | 8% – 12% | Excellent on specific pages |
If you're below 1%, you have a serious UX or value proposition problem. Between 1% and 3%, there's room to grow with targeted optimizations. And if you're above 5%, congratulations: your website is already selling.
Metric 3: Cost per qualified lead (CPL)
Simple in concept: if you invest €5,000 in a campaign and get 50 leads, your CPL is €100. But it's brutally revealing when you apply it to all your channels and compare them: it shows you which ones are profitable and which are draining your budget. Here are typical ranges in manufacturing:
| Channel | Typical CPL | Note |
|---|---|---|
| Organic SEO | €30 – €80 | Expensive to start, cheap in the long run |
| Google Ads | €80 – €250 | Fast and scalable |
| LinkedIn Ads | €150 – €400 | Expensive, but extremely high-quality leads |
| Trade shows and events | €300 – €1,500 | Premium if you follow up |
Without this metric, the debate over “where to invest the budget” is pure opinion. With it, it's a fact-based decision. And your CFO will thank you.
The 3 funnel metrics that set professional companies apart
Those first three tell you whether you're generating leads and at what cost. But a lead isn't a customer, and a customer isn't always profitable. To level up, you need to measure what happens between lead and revenue: how much each customer costs you, how much they're worth, and how long they take to close.
Metric 4: Customer acquisition cost (CAC)
CAC is everything it costs to win a new customer (marketing and sales salaries, tools, campaigns, fees, events) divided by the number of customers closed in the period. It's far more complete than CPL because it includes the cost of closing the sale, not just of capturing the lead.
A healthy CAC depends entirely on your average customer value: if your typical customer spends a lot each year, a high CAC can be excellent; if they spend little, that same CAC will sink you. The classic mistake is confusing a low CPL with a low CAC: one channel may bring cheap leads that never close, while another brings expensive leads with a high close rate. Only CAC tells you the real story.
Metric 5: Lifetime value (LTV)
LTV is how much revenue a typical customer generates over their entire relationship with you. In manufacturing, with recurring contracts or ongoing replenishment, it's probably the most important metric and the least well measured. The calculation is straightforward: average annual revenue × years retained × gross margin.
The golden number is the LTV/CAC ratio: how many times over a customer's value exceeds what it cost to acquire them.
< 3
Concerning
The customer barely pays back what it cost to acquire them. Review your costs or your retention.
3 – 5
Healthy
A solid range for an industrial B2B business growing sustainably.
> 5
Excellent
Plenty of margin to reinvest in acquisition and accelerate growth.
If you don't know this ratio, you don't know whether your marketing is profitable. Period.
Metric 6: Pipeline velocity (sales velocity)
In manufacturing, long cycles are the norm: 3 months for a small sale, 12–18 for a serious project. But almost no company measures exactly how long it takes a lead to become a customer. The formula is: (opportunities in pipeline × average deal size × close rate) ÷ average sales cycle length in days. The result is the revenue you generate per day of sales activity.
It's a strategic metric because it tells you where to accelerate and where to optimize: if the bottleneck is cycle length, you work on lead nurturing; if it's the close rate, you step up sales training; if it's deal size, you work on value positioning. Without measuring it, you're optimizing blindly.
The master metric that connects marketing and sales
The first six are granular: they tell you what happens at each stage of the funnel. But there's one that ties them all together, and your CEO or executive team will ask for it sooner or later. It's the final test: does the money you invest in marketing turn into profitable revenue? Putting it in place is what separates companies that treat marketing as an expense from those that treat it as an investment.
Metric 7: Marketing-influenced revenue and total ROI
The seventh and most important metric is marketing ROI: how many euros of revenue you generate for every euro invested. The key word is “influenced,” not just “closed.” In industrial B2B, almost no sale closes through marketing alone: it closes through the combined effect of your website, content, campaigns, trade shows, sales team, and referrals. Measuring only “leads from the website form” gives you an incomplete picture.
The professional approach is to attribute the share of each sale that was influenced by a marketing action (they visited the website, received an email, attended a talk, downloaded a case study). The total is your marketing-influenced revenue; divide it by total investment for the period, and you get your real ROI.
- ROI above 4 (four euros in revenue for every euro invested): healthy for industrial B2B.
- ROI below 2: there's a structural problem you need to tackle.
- It's the number that justifies growing budgets in front of the executive team.
What you take away from this article
- Vanity metrics (visits, followers, posts) measure activity, not business. Replace them with metrics that translate into euros.
- Start with the three basics: qualified leads (MQL/SQL), website conversion, and CPL by channel.
- Level up with the funnel metrics: CAC, LTV, and pipeline velocity. A healthy LTV/CAC ratio is between 3 and 5.
- The master metric is marketing ROI on influenced revenue; above 4 is healthy.
- Without a CRM, it's virtually impossible to measure CAC, LTV, pipeline, or ROI rigorously.
Frequently asked questions
Do I need a CRM to measure all these metrics?
Yes. Without a CRM (HubSpot, Salesforce, Pipedrive, Zoho), it's virtually impossible to measure CAC, LTV, pipeline velocity, or ROI rigorously. The good news: a basic B2B CRM starts at €50–100 per user per month, and the productivity gains pay back the investment within a few weeks.
How do I justify the marketing budget to the executive team?
By translating the numbers into euros and year-over-year comparisons. Instead of “5,000 more visits this month,” present “marketing ROI went from 2.8 to 3.6 this quarter, which means more influenced revenue.” The executive team understands that language and stops asking why you're investing in marketing.
How often should I review these metrics?
The basics (leads, conversion, CPL), weekly. Funnel metrics (CAC, pipeline velocity), monthly. Strategic metrics (LTV, marketing ROI), quarterly. And all of them consolidated in an executive dashboard you can scan in 30 seconds any morning.
Does this still apply if my industrial company is small?
It applies even more. The smaller your budget, the less you can afford to invest blindly. The tools scale (HubSpot Free and Google Analytics 4 cost nothing), and the metrics are the same for a company with €5 million in revenue as for one with 500. What changes is the rigor, not the list.
How do I tell a real MQL from a form filled out by mistake?
By clearly defining your criteria from the start: the requester's job title (decision-maker or influencer), company size (within your target range), industry (your service vertical), and stated reason (something specific, not “general inquiry”). Your sales rep qualifies them on first contact. Without a definition, your entire funnel gets polluted.
Can an outside agency help me set up the dashboard?
It's one of the services industrial company executives ask us for most. A good agency sets up the CRM, connects your website and campaigns, defines the qualification criteria, builds the dashboards, and trains your team to read them. Within a few weeks, you have a live dashboard you won't want to give up, plus the data to justify every euro invested.
