The goal is to increase profits from contextual advertising while maintaining the budget.
Tasks:
find out the number of hits from each ad and keyword;
determine which of them are most effective;
eliminate or optimize ineffective channels.
This is the simplest example. In practice, there are many more whatsapp number data goals and objectives, because each business has its own needs.
The second problem is the lack of UTM tags. Without them, it is impossible to properly analyze online advertising. UTM tags allow you to determine the sources of transitions to the site, that is, to determine effective and ineffective ads.
They are not always needed: one client came from organic search, another - from a direct link, a third - from a third-party site where a link without a label is posted. In most cases, the source of the transition will still be recorded. But in advertising, you can't do without them. After all, it is often unclear where the request comes from.
Analytics is a process, not a one-time action. It needs to be done continuously to increase business profitability.
Manage your incoming call flows correctly.
