There are those moments when you look at the numbers and ask yourself, “What do they actually mean?” In marketing, it’s easy to get lost in a flood of data, acronyms, and metrics. Website traffic, CTR, ROAS—all sound important. But which figures truly tell us whether our campaigns are working? And what about offline?

Today, I want to take you behind the scenes and show which KPIs have become most important to me as a marketing and sales expert.

Online Marketing: What Really Counts on the Dashboard

Website Traffic:
The classic metric: How many people visit my website, and where do they come from? Traffic is my first indicator of whether my activities generate reach. A closer look at bounce rate and page depth is worthwhile. For programmatic campaigns, session times are also interesting: in the age of AI, you often find so‑called “ad graveyards” that generate traffic only at 3 AM without any real value.

Impressions, Reach & Frequency Cap:
“How often” versus “how many.” Impressions show how many times an ad was served; reach tells me how many unique people I actually reached—crucial for branding. Viewability also plays a big role. According to the IAB standard “50/1,” at least 50 % of an ad must be visible for at least one second; this is a guideline, not a success benchmark. Equally important is the frequency cap—how often one person should at most see an ad. Overexposure leads to ad fatigue; underexposure can prevent the message from sticking.

Click‑Through Rate (CTR):
A trusty KPI friend: CTR reveals how compelling my content is to the target audience. But beware: many clicks don’t necessarily mean success if bounce rate is also high. Sometimes it’s just a big thumb on a smartphone tapping by accident—or the ad is perceived as annoying and quickly closed. The click‑to‑visit metric helps determine if clicks actually lead to site visits; if it’s low, reexamine your delivery strategy.

Conversion Rate & Conversions:
This is where it gets serious. How many visitors perform the desired action—whether purchase, signup, or download? And what are the absolute numbers? Essential for every funnel analysis.

CAC & CLV:
What does it cost to acquire a new customer (Customer Acquisition Cost, CAC), and what revenue do they generate over the entire customer relationship (Customer Lifetime Value, CLV)? Knowing both enables much smarter budget allocation. Note that CLV often materializes weeks or months after the first purchase.

ROI & ROAS:
Dry-sounding metrics that are pure gold. How much money actually comes back? Whether for paid campaigns or the overall budget, ROI (Return on Investment) and ROAS (Return on Ad Spend) show if the effort pays off.

Engagement & Email KPIs:
Likes, shares, comments—or, for emails, open and click rates. These metrics show whether the community merely sees or actively engages. Important social media KPIs also include post reach, engagement rate per post, and story completion rates. These figures offer valuable insights into which content resonates—and which doesn’t. More on evaluating social KPIs effectively in an upcoming blog post.

SEO, AEO & Cart Abandonment:
How visible am I on Google (visibility index, rankings)? Where do users abandon the purchase process? Two often underestimated areas.

Increasingly important is Answer Engine Optimization (AEO). In an era where AI‑driven search systems like Perplexity, ChatGPT, etc., provide direct answers instead of classic results, well‑structured, context‑rich content determines visibility. Content must be prepared so that language models can understand, select, and reuse it. In short: we now write for both humans and machines—fundamentally changing how SEO must be approached.

Offline Marketing: When Success Has No Pixels

Offline marketing has KPIs, too—though they’re often less directly measurable:

Reach & Frequency:

How many people saw the message, and how often? On TV, this is measured via GRP (Gross Rating Point), which combines reach and contact frequency.

Response Rate: Did people react (e.g., through increased in‑store purchases)?

Customer Acquisition: How many new contacts came through offline channels?

Brand Awareness: How well do people know my brand? Surveys and market studies help here.

Brand Perception: According to Byron Sharp, recognition alone isn’t enough; linking the brand to specific usage situations—Category Entry Points (CEPs)—is crucial.

ROI: Offline investments must pay off, too.

Recent research shows that offline media are particularly effective when part of an integrated media mix. Print, TV, or out‑of‑home not only support brand building but also measurably boost digital channels—an effect long underestimated by attribution models.

What Science Says: Byron Sharp

In How Brands Grow, Byron Sharp demonstrates that reach is not a nice‑to‑have but a decisive success factor. Brands grow when they regularly reach as many potential buyers as possible—regardless of whether they’re actively searching or not.

That means it takes not only dashboards but also experience and intuition. Reach may not immediately translate into conversions or ROAS, but it builds long‑term visibility, availability, and purchase readiness in consumers’ minds—online and offline.

Conclusion: Choose Your KPIs Wisely

Not every metric is relevant for every goal. Select KPIs that align with your strategy, rather than ticking boxes. KPIs are tools, not end in themselves.

The concept of Category Entry Points (CEPs) lies at the heart and those who learn to ask the right questions of their data will get the answers that truly matter.
