Performance marketing

Cheap leads can make growth expensive.

Cost per enquiry is useful. It becomes misleading when it stands in for the quality of the conversation that follows.

The denominator changes the story.

Imagine two hypothetical campaigns with the same spend. One generates more forms; the other produces more qualified conversations. Calling the first campaign the winner because its cost per form is lower settles the question before examining the outcome.

The problem is not the cost-per-lead metric itself. It is the assumption that every counted lead represents the same opportunity.

Define useful before optimising for more.

Agree the conditions that make an enquiry relevant: the need, territory, offer fit and any other justified criteria. Keep contactability separate from qualification. A person you cannot reach and a person who does not fit the offer are different problems.

Then make those dispositions usable for the team. A sophisticated qualification model that nobody updates provides less practical feedback than a small, consistently maintained set of stages.

Diagnose the part that changed.

Observation Investigate before concluding
More forms, less relevance Targeting and the promise in the ad
Relevant enquiries, few contacts Contact details, response and assignment
Good conversations, little progression Offer fit and the sales process
Different totals in each report Definitions, periods and duplication

Give the campaign team something actionable.

A report saying “bad leads” does not identify a change. A report showing service mismatches from a particular message gives the team a hypothesis to test. The feedback should be specific enough to change the next decision.

Do not attribute every lost opportunity to advertising. Sales handling, product fit and availability can affect the outcome. Equally, do not use those dependencies to avoid investigating weak acquisition.
