How Ratings Work

Community scores reflect the collective experience of Routine Shelf members — weighted toward reviews that demonstrate genuine, firsthand knowledge.

Having a product on your shelf signals real ownership. Writing about your experience shows thoughtful reflection. Adding a photo grounds your review in reality. Each of these contributes more to the community score than a quick rating alone.

We believe that someone who owns a product, has used it over time, and takes a moment to share their honest experience offers more to the community than a quick star tap. Our scoring reflects that belief.

There are no “power users” or influence levels. A new member who writes a thorough review carries the same weight as someone who’s been here for years. What matters is the effort you put into each review — not how many you’ve written.

Not all scores are created equal. A product with hundreds of reviews and a score of 4.2 tells a very different story than a product with 2 reviews and a score of 4.2.

That’s why each score is shown alongside the number of ratings behind it. Products with very few ratings appear with a softer, more transparent score — a visual reminder that the number is still forming. As more reviews come in, the score solidifies.

The tier distribution on every product page shows the full picture — how many members rated each tier. We believe this tells a richer story than any single number.

Every review shapes the community’s understanding of a product. Here’s how to make yours count:

We don’t adjust scores to favor brands, products, or users. The methodology described on this page is the complete system — no hidden factors, no secret adjustments. If we ever change how scores work, we’ll tell you here first.
