Evidence Synthesis
We synthesize multi-source product evidence into a single score designed to reflect quality, reliability, sentiment, and trade-offs.
Our Evaluation Standards
Buyary
Methodology
Buyary Scores help shoppers understand product evidence across expert reviews, customer feedback, creator analysis, scientific research, product data, and community discussions, guided by standards for transparency, independence, and evidence quality.
What the Buyary Score
Represents
The Buyary Score reflects Buyary's overall evaluation of a product based on available evidence. It is not a single reviewer's opinion, a retailer rating, a popularity contest, or a paid placement.
Bias-Aware
Our framework accounts for potential review bias, outliers, incentives, and inconsistent sentiment when evaluating product evidence.
The Framework
How Scoring Works
The Buyary Score is a 0-100 composite built from structured analysis across multiple source types. A higher score reflects stronger, more consistent evidence of quality across experts, customers, creators, product data, and research where relevant.
- Expert review sentiment and consensus
- Customer review sentiment and volume
- Creator and video reviewer analysis
- Product specifications and manufacturer claims
- Reliability and durability signals
- Value relative to comparable alternatives
- Category-specific performance factors
- Areas of disagreement between sources
Why 0-100?
A 0-100 scale makes it easier to compare products within a category. It gives shoppers a quick summary while still allowing them to inspect the sources, trade-offs, and evidence behind the score.
Note: Buyary Scores are not paid placements. Scores are not determined by advertisers, retailers, brands, affiliate commissions, or sponsored arrangements.
Source Quality
Matters
Not all reviews carry the same evidentiary weight. Buyary evaluates sources based on category expertise, transparency, testing rigor, supporting evidence, historical reliability, and relevance.
01
Testing Rigor
Buyary prioritizes sources that demonstrate hands-on usage, structured evaluation, long-term testing, measurable performance criteria, or specific product evidence over superficial impressions.
02
Transparency
Sources that clearly disclose testing methods, funding, sponsorships, and potential conflicts may receive greater evidentiary weight.
03
Consistency
We consider whether a source provides reliable, specific, and well-supported analysis over time, especially across product generations or comparable categories.
Diverse Data Sources
Buyary analyzes a range of sources, including expert publications, specialist reviewers, creator and video reviews, customer reviews, retailer ratings, product specifications, scientific literature, peer-reviewed research, owner forums, product communities, and long-term reliability discussions where relevant.
When Sources Disagree
Experts, customers, creators, and researchers do not always agree. When sources reach different conclusions, Buyary evaluates the quality and strength of the supporting evidence rather than relying solely on popularity or majority opinion.
"Buyary does not reward the loudest opinion. It prioritizes the best-supported evidence."
Scientific & Peer-Reviewed Research
In categories where health, wellness, safety, durability, environmental impact, or product effectiveness matters, Buyary may incorporate scientific literature and peer-reviewed findings alongside expert and consumer evidence.

Core Principles
Evaluation Standards
Buyary's evaluations are guided by five core standards that define how we assess product evidence.
01
Accuracy
We aim to verify important claims against credible sources, manufacturer documentation, expert reviews, third-party testing, and real-world feedback.
02
Transparency
We cite the sources behind product evaluations and explain the standards used to assess evidence quality, relevance, and reliability.
03
Independence
Commercial relationships do not determine Buyary Scores, rankings, source selection, or editorial conclusions.
04
Relevance
Evidence is evaluated in context. Recent reviews, category-specific expertise, and current product versions carry more weight.
05
Evidence Quality
We prioritize specific, supported, and testable claims over general praise, vague complaints, or marketing language.
Detailed Evaluation Standards
Accuracy
Buyary's accuracy standard is designed to ground product evaluations in verifiable evidence rather than unsupported sentiment alone. We compare product claims against available specifications, expert analysis, third-party testing, scientific research where relevant, and real-world consumer feedback.
Independence
Buyary separates editorial evaluation from commercial relationships. Affiliate partnerships, sponsored placements, and business relationships do not determine Buyary Scores, rankings, source selection, or editorial conclusions. Revenue considerations are not part of the scoring process.
Evidence Quality
Buyary prioritizes sources that provide clear reasoning, specific observations, testing details, product data, photos, measurements, or other supporting evidence. Sources may receive less evidentiary weight when claims are vague, unsupported, outdated, inconsistent, or not relevant to the product category.

Time
Products are not static. Firmware updates roll out, defects emerge, models are revised, and long-term ownership feedback accumulates. Buyary Scores are updated as new evidence emerges.

Reliability Info
Buyary's goal is to reflect the best available evidence, not freeze a product's evaluation at one point in time.
