BuyViao comparison methodology

1. Product identity comes first

We prefer exact product-model evidence before we compare retailers. Strong signals include manufacturer model numbers and standardized identifiers. We do not intentionally merge variants that differ in material specifications, storage, size or generation.

2. No forced matches

If two retailer listings cannot be matched with enough confidence, they should remain separate or be held for review. A missing comparison is less harmful than a wrong comparison.

3. Offer data keeps provenance

Offer records are designed to retain the merchant, source, currency, price, availability, delivery information and last-checked timestamp. Source-specific retention or display rules take priority over BuyViao preferences.

4. Best does not mean highest commission

Where offers are ranked, shopper value should drive the order. Depending on the page, that may include total purchase price, shipping cost, delivery timing, stock status and useful store characteristics.

5. Editorial and commercial signals are separate

Affiliate status can affect whether a link earns revenue, but it should not change factual product data or editorial conclusions. Sponsored placements, if introduced, will be clearly labeled.

6. Corrections matter

If a product match, price or store statement is wrong, we want to correct it. Readers can contact us at hello@buyviao.com.
