This is an example of a campaign in action, using all of the knowledge you have gained so far.
Every campaign is different, either slightly or vastly in some cases, but this is just one example to see how things come to life.
This brand wanted to test with us, and at first had only "general population" creative, meaning the creative only featured the product, an an all-English language copy and CTA. They deployed both display and preroll, regionally, since this was for a Tier 2 effort. In automotive, Tier 2 refers to regional, while Tier 1 is national, and Tier 3 is individual dealerships.
We offered to translate their creative as added value, meaning for free, but they wanted to test "apples to apples" against all of their other campaigns using the same creative strategy, so we stuck with the original creative. The campaign used several high-impact overlay executions as well as standard, and 15s and 30s video.
Here is what it looked like:

After every campaign, our practice is to provide a deck that sums up the campaign in total, including execution, what it looked like, the performance it drove, the relative performance across our different ethnic segments and asset types and sizes, and more in some cases. This is our chance to highlight every bit of positive impact we've made, and the more in-depth the better, in all cases.
Here is what a couple of slides looks like from one of these:


The post campaign wrap-up report is our chance to make our bid for the next effort, in essence. It makes the case for why we were a good partner, and why they should work with us again.
In this case, we went on to work with this client for several years after, with increased budgets each time, based on the strength of our performance.
