Your own record is what defends the finding: One report is a claim. A dated series of reports plus the decisions taken on them is a track record, and scepticism responds to those very differently.

Causal inference
One report is a claim. A dated series of reports plus the decisions taken on each is a track record, and scepticism responds to those very differently. The record is built months before it is needed.
What a record contains
| Field | Why it defends you |
|---|---|
| Date and window of each read | Makes the series comparable |
| Estimate, interval, coverage per channel | Shows which calls rested on strong evidence |
| The decision taken | Connects measurement to action |
| What would have changed it | Proves the reasoning was falsifiable at the time |
| What actually happened afterwards | The only real validation available |
The last row is what converts a log into evidence. Six months of "we predicted X, we did Y, Z happened" is a much stronger answer to a sceptic than any single well-argued report.
Why this beats arguing about method
A sceptic who does not trust causal inference is not going to be converted by an explanation of causal inference. They may well be moved by a record showing that decisions taken on these reads worked out, and that the ones with wide intervals were treated more cautiously.
That is an empirical argument about your process rather than a theoretical one about statistics, and it is the argument most likely to land with someone whose objection is really about trust.
Keeping it outside the tool
The record belongs in a document you control, not in a vendor's interface. Vendors hold numbers, not reasoning, and access usually ends with the contract. The habit and the template are in keeping the attribution record in your own workspace and the ownership argument in you do not own your attribution data.
The annual review
Once a year, take every logged decision and check it. Which channels did you scale, and did revenue follow. Which did you cut, and what changed. Which reads had wide intervals that you acted on anyway.
That review is the single most useful marketing document a brand can produce, and it is impossible without the log. It is also the thing you bring when someone asks whether any of this measurement has ever been worth it.
What to record from each read
Per channel: estimate, confidence interval, coverage share, design label, plus the list of channels that could not be measured. That is what a €99 one-time read on a Google Analytics export returns, refundable if it does not move a budget decision. A reproducible series without manual uploads sits on Pro at €299 a month with the direct integrations, unlimited uploads, developer API keys and the MCP server.
Start it late if you have to
If you have no record, start today with one line and stop worrying about the missing history. Six months from now the log will be the reason a sceptical conversation goes differently, and six months from now is closer than it sounds.
