Affiliate is a **commercial/monetization relationship**; metasearch is a **product and search/comparison pattern**. A metasearch product may monetize through affiliate relationships, but not every affiliate experience is metasearch.

## Comparison

| Dimension | Metasearch | Affiliate |
|---|---|---|
| Primary definition | Multi-provider discovery/comparison | Referral/commercial relationship |
| Search aggregation | Usually | Not required |
| Offer normalization | Core problem | Not required |
| Deeplink | Common | Very common |
| Booking ownership | Usually downstream | Downstream merchant/provider |
| Revenue | CPC/CPA/referral/ads | CPA/revenue share/CPC |
| Attribution | Click/search context | Click/conversion/commission |

## Example

```text
Metasearch:
user search
 -> multiple providers
 -> normalized offers
 -> comparison
 -> provider deeplink

Affiliate content site:
article
 -> one/more tracked links
 -> merchant landing
 -> conversion
```

The second flow can be affiliate without being metasearch.

## Architecture impact

Metasearch needs supplier adapters, canonical search requests, offer deduplication, freshness, ranking and partial-result behavior.

Affiliate systems emphasize tracking IDs, deeplink construction, attribution windows, conversion callbacks and commission reconciliation.

## Measurement

Metasearch KPIs include coverage, price freshness, latency, CTR and landing accuracy.

Affiliate KPIs include clicks, conversion, approved bookings, cancellations, commission and EPC/revenue.

## Checklist

- [ ] Are product pattern and monetization model kept separate?
- [ ] Is click_id/sub_id lineage preserved?
- [ ] Is booking/cancellation reconciliation implemented?
- [ ] Is metasearch offer freshness measured separately?
- [ ] Is affiliate commission state separate?
