Leading vs Lagging Indicator
AnalyticsAlso: Leading Indicator · Lagging Indicator · Leading and Lagging Metrics
Quick definition
A leading indicator is a metric that moves before a result and can predict it, like traffic or pipeline volume. A lagging indicator is a metric that confirms a result after it's happened, like revenue or churn. Leading indicators tell you what's coming. Lagging indicators tell you what already arrived.
How it varies across Australia
Most Australian reporting decks lean heavily on lagging indicators like revenue and conversion rate because they're easier to source from finance. Businesses with mature reporting tend to pair every lagging metric with at least one leading metric that moves weeks or months earlier.

Moves before the outcome. Predictive, noisy, actionable.
Example: MQL volume, traffic, CTRConfirms the outcome after it happens. Certain, but too late to act on.
Example: revenue, churn, LTVWhat it actually means
Think of driving a car. The speedometer is a leading indicator. It tells you right now whether you're about to get a fine or crash into something. The fine itself, or the repair bill, is the lagging indicator. It confirms what already went wrong, well after you could have done anything about it.
Marketing reporting is full of both, and most teams over-invest in lagging ones because they're easier to defend in a board meeting. Revenue, churn rate, customer lifetime value, these are lagging. They tell you the truth, but only after the truth has already cost you something.
Leading indicators are earlier and noisier. Website traffic, marketing qualified lead (MQL) volume, email open rate, ad click-through rate (CTR), these move before the lagging outcome shows up. They're less certain, which is exactly why people distrust them, but they're the only numbers that give you time to act.
Good reporting pairs the two. A drop in organic traffic (leading) this month explains a drop in conversion rate (lagging) three months from now. If you only look at the lagging number, you find out the problem existed a full quarter after it started.
A lagging indicator tells you the accident already happened. A leading indicator is the one that could have warned you.
How it shows up
In a marketing dashboard, leading indicators sit near the top of the funnel: impressions, traffic, MQLs, email signups, add-to-cart rate. Lagging indicators sit near the bottom: revenue, customer acquisition cost (CAC) once fully loaded, churn, net promoter score (NPS) collected after a support interaction.
It also shows up in how a business reacts to bad news. A team watching leading indicators spots a dip in pipeline volume and adjusts spend before the quarter closes. A team watching only lagging indicators finds out at quarter end that revenue missed target, with no time left to fix it.
The Australian context
Australian boards often ask for lagging metrics almost exclusively, revenue, margin, churn, because they map cleanly to financial reporting cycles. That's reasonable for the board pack, but it leaves marketing teams reacting to problems a full quarter late. Businesses that also report a small set of leading indicators, pipeline coverage, organic traffic trend, engagement rate, catch problems while there's still budget left in the quarter to fix them.

Common questions
What's an example of a leading indicator in marketing?
Website traffic, marketing qualified lead volume, email open rate and ad click-through rate are all leading indicators. They tend to move weeks or months before the outcomes they predict, like revenue or new customers, actually show up.
What's an example of a lagging indicator in marketing?
Revenue, churn rate, customer lifetime value and fully loaded customer acquisition cost are lagging indicators. They confirm what already happened but arrive too late to change the outcome they're reporting on.
Should I report leading or lagging indicators to my board?
Both, paired together. Lagging metrics like revenue satisfy the need for certainty. Leading metrics like pipeline coverage or traffic trend give the board an early warning before the lagging number confirms a problem that's already too late to fix.
Why do leading indicators feel less trustworthy?
Because they're probabilistic, not certain. A traffic spike might convert or might not. That uncertainty makes people default to lagging metrics, even though waiting for certainty means waiting until it's too late to act on the information.
