Most website reporting measures activity rather than outcome. Traffic went up, time on page went down, and nobody can say whether the project paid for itself. Three numbers change that conversation.
1. Qualified enquiries per month
Not form submissions — enquiries your sales team would actually take a call about. Counting the unqualified ones rewards a site that generates noise. Agree the definition of qualified before launch, because agreeing it afterwards is how the metric gets negotiated.
2. Time to first meaningful action
How long from landing until a visitor does the thing the page exists for. This is where performance work shows up in commercial terms: a visitor who waits four seconds to see your pricing is measurably less likely to ask for it.
3. Share of enquiries that arrive informed
Track how many people reach you already knowing what you charge, how you work, and what they want. A site doing its job shortens the sales conversation. A site that generates a pile of "what do you do?" emails is generating work, not leads.
Measure before you build
All three need a baseline, which means instrumenting the current site before it is replaced. This is the step that gets skipped, and skipping it is why so many redesigns can only be defended on taste. Two weeks of before-data is worth more than any amount of after-data on its own.
- Define what counts as qualified, in writing, with the people who handle enquiries.
- Record the current numbers for at least a fortnight before anything ships.
- Re-measure on the same days of the week, since weekday and weekend traffic rarely behave alike.
