If a VK post and ads are running at the same time, keep the known source of each inquiry and a separate "unknown" category. Do not distribute all leads between channels by share of views: such a proportion has no evidence-based connection to buyers.
Minimal log
For each inquiry, you need the date, an internal anonymized number, the confirmed source, the status, and the method of determining the source. Keep a tagged link, the client's answer, and an employee's guess as different levels of confidence. Do not publish real client data.
A hypothetical example: ten inquiries, four have a confirmed ad tag, three came from a post, and for three the source is not established. The report keeps 4 / 3 / 3. You cannot turn the unknowns into ads just because it received more impressions.
How to prepare the inputs
For external transitions to your own website, use agreed tags and check that they reach the page. The rules for processing UTMs depend on the analytics system; Metrica describes them in its official help. The mere presence of a tag in the address does not confirm payment and does not solve cross-device transitions.
If an inquiry came directly to messages without a measurable transition, you can voluntarily ask where the person learned about the offer. This is self-reporting, not an exact technical source. Do not pressure the client and do not require them to choose between two channels if they do not remember.
Separate the inquiry and the money
Several messages may relate to one inquiry, but that is not several leads. Confirm payment with separate accounting, subtract refunds, and mark a repeat purchase separately. When comparing channels, use the same window and show the share of unknown source.
