Client: programmer.
Task: get an order to create websites by calling and discussing details over the phone.

What was done:
there was a standard setup of targeted ads for placements – Facebook, etc.
I didn’t set up Instagram, because after determining the target audience by tasks and prices, I realized that spending the client’s budget on Instagram is not cost-effective.

So, I set up an ad and launched it.
The screenshot below shows the results of one day of advertising operation.

What are the results: there were no conversions for the first two days of the ad’s operation. On the third day, 2 calls were received. The first one was not successful, but the second one was doubly successful, because the client ordered a website and landing page.

On the last day of advertising, there was another call and we ordered a landing page.

Of course, they also discussed the cost and recalculated it repeatedly, but the approximate profit of my client for 7 days of advertising can be calculated:

Expenses-дол 5 / day = 3 35 / 7 days
Profit-site 3 300. + landing page дол 100. + landing page дол 100. = Дол 500. (prices were taken on average by my client)

In total, targeted advertising allowed you to get дол 500 in profit with an investment of 3 35 (subject to successful cooperation).
