Case is targeted advertising. Sales of clothes

Task: Get hot contacts for wholesale buyers from the clothing manufacturer.
Since the client's website was not conversion but information, they decided to launch advertising on the lead form.
In parallel, they also launched a traffic company on the site as a test.
As a result - cheap clicks with the passage to the site, and quite cheap requests with the lead form.
Low conversion to application from the site, and high conversion to application and sales from the lead form.
