The RefDat Score: Weighted Aggregation

The RefDat Score is a calculated aggregate of multiple independent review sources. Rather than relying on a single review platform, we combine data from multiple sources to reduce bias and noise.

The RefDat Score ranges from 0-10, where 10 is excellent and 0 is poor.

Data Sources for Aggregation

RefDat collects review data from multiple independent sources including Amazon, major Australian retailers, specialist review sites, and consumer feedback platforms. Each source is weighted based on review volume and recency.

We normalise all scores to a 0-10 scale for comparison and aggregation.

Weighting System

Not all reviews are equal. RefDat weighting accounts for:

• Review Volume: Products with more reviews get slightly more weight (larger sample size = more reliable average)
• Recency: Recent reviews are weighted more heavily than old reviews
• Verified Purchases: Verified purchase reviews are weighted more heavily than unverified
• Source Reputation: Reviews from larger, more established platforms are weighted more heavily

What RefDat Doesn't Do

RefDat Product Reviews does NOT:

• Accept sponsored placements or paid promotions
• Filter or remove negative reviews
• Allow manufacturers to comment or contest ratings
• Adjust scores based on advertising relationships

Product Selection Criteria

RefDat covers 158 Australian products selected based on:

• Popularity in the Australian market
• Availability from major retailers
• Sufficient review volume to calculate a reliable score
• Relevance to Australian consumers

Price Tracking Methodology

RefDat tracks prices for products across major Australian retailers (Amazon, Bunnings, Woolworths, etc.). Price data is updated weekly and reflects recommended retail prices plus current promotional pricing.

Price comparisons assume Australian pricing. International pricing is not included.

Limitations and Caveats

Product quality is subjective. A high RefDat Score means that aggregated reviews are positive, not that every user will love the product. User reviews reflect individual experiences and preferences.

RefDat Scores are calculated based on available reviews. Very new products may have limited review data.
