# Ad Click Rate Unit Check

Check whether campaign rates use counts, proportions or percent units before comparing ads.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Comparable click/impression counts, rate definitions, export units and approved zero-denominator rule.

## Workflow
1. Preserve counts and stated rate units for each row.
2. Calculate clicks/impressions only for comparable scopes and nonzero denominators.
3. Distinguish proportion 0.02 from percent 2; do not infer missing units from appearance.
4. Return a calculation table; no campaign optimization or advertising changes.

## Output contract
campaign | clicks | impressions | units | proportion | percent | gap

## Fictional acceptance test
Fictional 20 clicks/1000 impressions gives 0.02 or 2%. A value 2 without units is unresolved; zero impressions does not produce a finite rate.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
