Analytics platforms will report hundreds of metrics. Most of them describe activity rather than outcomes, and reporting on activity is how marketing teams end up looking busy while the business asks what any of it produced.
Vanity versus decision metrics
A metric earns its place if a change in it would change what you do next. Total pageviews rarely qualifies. Conversion rate on your pricing page does. Social followers rarely qualifies. Revenue per email recipient does.
The test: if this number doubled tomorrow, would anything about the business change? If not, stop reporting it.
The core set
- Customer acquisition cost. Total spend, including salaries and tools, divided by new customers. Blended across channels is more honest than per-channel figures built on contested attribution.
- Customer lifetime value. What a customer is worth over the relationship. The ratio of lifetime value to acquisition cost is the single number that tells you whether growth is sustainable. Below three to one and you are usually buying revenue at a loss once overhead is counted.
- Conversion rate by stage. Visitor to lead, lead to opportunity, opportunity to customer. Isolating which stage leaks tells you where to work.
- Payback period. How many months until a customer repays their acquisition cost. This determines how fast you can safely scale spend.
Channel metrics worth watching
For organic search, track non-branded impressions and clicks separately from branded. Branded search reflects marketing you did elsewhere; non-branded reflects whether SEO is working. Also watch the share of your indexed pages that receive any traffic at all, which reveals content bloat.
For paid, watch cost per acquisition against your target and impression share lost to budget, which tells you whether there is headroom to scale.
For email, use revenue per recipient rather than open rate, since privacy features made opens unreliable.
For content, track assisted conversions. Content usually appears early in the journey and receives little credit under last-click attribution, which is how good content programs get defunded.
Attribution will never be exact
Privacy changes, cookie restrictions, cross-device journeys, and dark social mean a meaningful share of influence is unmeasurable. Rather than chasing a perfect model, use three imperfect checks together: your analytics platform, self-reported attribution on signup forms (a single “how did you hear about us” field is remarkably informative), and holdout tests where you pause a channel in one region and observe what happens to total demand.
Build the report backward
Start with the question the business is asking, usually some form of “is this producing profitable growth.” Choose the smallest set of numbers that answers it. A one-page dashboard with six metrics that drive decisions beats a forty-tab report nobody opens.
Set the review rhythm
Check campaign-level numbers weekly, channel performance monthly, and strategy quarterly. Reacting to daily fluctuations produces noise-chasing, which is expensive. Most channels need at least a month before a change in direction is real rather than random.
