The Post Mortem On A Campaign That Failed

Most failed campaigns are quietly switched off and never discussed again. The budget is reallocated, the creative is archived, and the next thing starts.

Which means the same failure is available to be repeated in six months, because nobody wrote down what happened.

Do it inside a fortnight

Memory degrades fast and the reconstruction is always kinder than the reality.

Two weeks after the campaign ends, with the people who ran it, in an hour. Any later and you are writing a story rather than a record.

Establish what the campaign was for

The first question is almost always the problem: what was this supposed to achieve, and what number were we going to read.

A campaign with no stated target cannot fail, which is exactly why so many of them are set up that way. If nobody can answer this question now, that is the finding, and the fix is upstream of the next campaign.

Separate the four kinds of failure

This is the whole value of the exercise, because the fixes are completely different.

A measurement failure. The campaign may have worked. The tracking was broken, the conversion did not fire, the attribution window was wrong, or the offline outcomes were never fed back. More common than anybody expects, and the first thing to rule out.

An execution failure. The plan was right and the delivery was not. Launched late, wrong audience loaded, budget capped, creative approved in the wrong format, landing page broken on mobile.

A creative failure. The offer and the targeting were right and the work did not land. Hook, format, length, voice.

A strategic failure. The execution and creative were fine and the premise was wrong. Wrong audience, wrong offer, wrong channel, wrong time of year, wrong price.

Fixing creative on a strategic failure is the most common waste in marketing, and it happens because nobody separated the two.

Then read the sequence, not the total

The useful view is the funnel in order.

Impressions to clicks tells you about the creative and the targeting. Clicks to enquiries tells you about the landing page and the offer. Enquiries to quotes tells you about qualification. Quotes to sales tells you about price, process and follow up.

The stage where it fell over is the finding. A campaign with strong click through and no enquiries is not a creative problem, however much the creative is what everybody wants to discuss.

Write it down in one page

Four sections, one page, stored where the next person will find it.

What we tried, including the numbers and the dates. What happened, with the funnel stages. Which of the four failures it was, stated plainly. What we will do differently, as one or two specific changes rather than a list of improvements.

A post mortem that produces nine action items produces none of them. Two is a real commitment.

Keep what was fine

A failed campaign usually contains working parts, and binning everything is as wasteful as repeating everything.

The audience that responded, the one creative that performed, the landing page that converted, the subject line that got opened. Those go into the library, labelled, because the next campaign starts from them rather than from nothing.

No blame, and no comfort either

A post mortem where everybody agrees it was market conditions is worthless. So is one where somebody gets blamed, because the next one will be quietly buried.

The useful framing is that the campaign was an expensive test and the only failure available now is not learning from it. Then say the uncomfortable thing if it is true: the offer was not strong enough, the price was wrong, the premise did not hold.

Where it goes

Into the quarterly review, so the pattern across several campaigns is visible rather than each one being treated as an isolated event.

Three post mortems in a year with the same stage failing is not three campaign problems. It is one business problem, and that is the finding worth having.

What this unlocks: a record that makes the next campaign start from evidence rather than from instinct.
