This page explains the practical checks we use to reduce false matches, suspicious listings, and low-confidence merchant outcomes.

Expanded with product-match controls, unresolved-link handling, and manual correction channels.

1) Product match quality

We test whether search results represent the requested product family and variant. Family mismatches are filtered when the query is clearly specific.

We also score relevance from title and extracted page signals to avoid surfacing tangential discussion pages as product offers.

2) Merchant and URL quality

Merchant links are checked for resolver failures, suspicious redirects, and non-product destinations. Results that fail validation are downgraded or excluded.

When source URLs remain unresolved from shopping feeds, we run additional fallback resolution and keep confidence signaling explicit in the UI.

3) Price integrity checks

We compare feed prices against merchant-page extractions where possible and flag major divergence. We also isolate outliers and suspiciously low listings for closer review.
