Case

Detailed explanation

In a marketing glossary, “case” is shorthand for a case study — a written account of a real campaign, client, or project that walks through the starting situation, the actions taken, and the measurable outcome. It is less a metric than a format: a way of presenting evidence rather than a number you calculate.

A useful case does more than report a win. It states the baseline (traffic, conversion rate, or spend before the change), the specific intervention (a new landing page, a bidding strategy, a content overhaul), the timeframe, and the result in the same units as the baseline, so readers can judge cause and effect rather than take a headline percentage on faith. Cases that skip context or compare unlike periods are the ones worth reading skeptically.

For “what does case mean” or “how to read a marketing case study” searches, this entry is a starting point. Look at the case studies linked across glossary terms such as CTR and ROAS to see the format applied to real numbers.
