Plenty of people avoid estimating campaign results because it feels like signing up to a promise. The effect is the opposite of the one intended: with no estimate, when a campaign goes badly nobody can say where it went off.

The five numbers

Budget and CPM give you impressions. CPM swings hard by industry, season and network: in November it rises everywhere.

Click-through rate turns impressions into clicks. Under 1% on social is normal; far above it usually means an audience that is too small or a promise the ad cannot keep.

Conversion rate turns clicks into results, and is the one least influenced by the ad. It depends on the page people land on.

Value of one result closes the sum. Without it you know what it costs and not whether it was worth it.

How to use it

With numbers from your own past campaigns. With no history, use industry references and write next to them that they are industry references: a client takes an estimate with explicit assumptions well, and takes a number with no origin very badly.

What to do mid-campaign

Compare. If impressions are on plan but clicks are not, the problem is the creative. If clicks are there and conversions are not, the problem is the page. That is what an estimate is for: not to be right, to know where to look.

A note on return

The ratio here is estimated revenue over ad spend. It does not count the hours of whoever builds and runs the campaign. For the full sum, add what comes out of the cost per post calculator.

Prompt: turn a monthly report into something a client reads

If a number went up because of a single post, say so. That is the difference between a report and a sales deck.

Numbers do not convince on their own. The prompt that turns a month of metrics into three paragraphs a person actually reads.

You have last month's data for a profile. Write the executive summary of a report for a client who
does not work in marketing.

Required structure, three paragraphs:
1. The most relevant thing that happened, with the number that proves it.
2. Why it happened, tied to concrete decisions we made.
3. What we will do next because of it.

Rules: no technical term without an explanation in the same sentence. No percentage without the
absolute value beside it. If a number went up because of a single post, say so. If any indicator
got worse, it belongs in the summary, not buried in the tables.

200 words maximum. Do not invent causes: if the data does not explain a change, write that it does
not.
