How Recommendation DNA Works

Recommendation DNA is an analysis framework utilized for scoring audiobooks based on a set of quality dimension criteria (which will be explained below). Additionally, we use what we call “listening-profile” and “listener-fit” indicators to provide and explain what the audiobook experience may feel like and who might be best suited for that audiobook. These set of criteria are applied the same across all the audiobooks.

The score tells every user how the audiobook performs based on criteria that are the most important components for the audiobook experience. The “DNA” essentially tells you why the audiobook is really good or not so good. We use ‘evidence confidence’ to tell you how strong the data is and how much confidence supports it.

What Recommendation DNA Measures

Recommendation DNA separates quality, experience, and fit so readers can understand what the score means at a glance.

1

Quality Dimensions

These determine the Recommendation Score itself.

  • Eight weighted quality dimensions
  • Narration and story carry the most influence
  • Same framework for every audiobook
2

Listening Profile

These describe what the listening experience feels like.

  • Pacing, tone, humor, romance, complexity, and more
  • Higher score = more prominent, not better or worse
  • Helps readers understand the experience
3

Listener Fit

These help show who the audiobook may suit best.

  • Commute, road trips, bedtime, workouts, and more
  • Shows ideal listening situations
  • Does not affect the quality score

What Contributes to the Recommendation Score

These eight quality dimensions make up 100% of the score.

Narration Quality
17.8%

Story Quality
17.1%

Character Development
12.5%

Emotional Impact
11.8%

Audio Production
11.2%

Originality
10.5%

Replay Value
9.9%

World Building
9.2%

Listening traits such as humor, romance, violence, and complexity describe the experience, but do not increase the quality score.

Example: How a Score Is Calculated

Sample audiobook with a final score of 8.7/10.

Quality rating × fixed weight = contribution to the final score
Quality Dimension Rating Weight Contribution
Narration Quality 9.4 17.8% 1.67
Story Quality 8.8 17.1% 1.50
Character Development 8.3 12.5% 1.04
Emotional Impact 8.7 11.8% 1.03
Audio Production 9.0 11.2% 1.01
Originality 8.1 10.5% 0.85
Replay Value 8.0 9.9% 0.79
World Building 8.5 9.2% 0.78
Total — 100% 8.67 → 8.7
Small changes in one dimension can affect the final score, but the weighting remains the same for every audiobook.

Recommendation Score: What It Means

Limited Recommendation
Below 5.0

Mixed or Niche Appeal
5.0 – 6.4

Solid
6.5 – 7.4

Recommended
7.5 – 8.4

Highly Recommended
8.5 – 8.9

Exceptional
9.0 – 10.0

Evidence Confidence: How Strongly the Score Is Supported

Evidence Confidence doesn’t change the outcome value; it provides reliability strength to the score based on independent evidence for that audiobooks result.

High Confidence

75–100%

Broad, consistent support across multiple independent sources.

Moderate Confidence

55–74%

Useful supporting evidence is available, but important gaps remain.

Limited Confidence

Below 55%

The result is incomplete or lacking quality evidence. That doesn’t mean the evidence isn’t out there, it just means we didn’t grab it.

What Readers Should Remember
