Targeting - collection of leads to visit the business forum

The campaign is aimed at gathering leaders to visit a large business forum in Lviv. Since when choosing the ticket payment, the visitor was redirected to a third-party resource, then to track the conversion completely failed. The project was not long and quite difficult, the expected results unfortunately failed to be achieved, but the customer remained satisfied as traffic was enough and he adequately understands that there are other factors affecting the final result.
The screen shows that there were 30 conversions, 2,496 transitions, 114,623 people covered, 492 euros spent.
