Structured data

LOW

Product `aggregateRating` present

Each Product JSON-LD node carries an AggregateRating with ratingValue in [0,5] and reviewCount/ratingCount ≥ 1. Review ratings are a trust signal agents use to rank and filter products.

What this check looks for

Aggregate ratings drive agent rankings and rich results. Valid means `ratingValue` parses to a number in [0,5] and `reviewCount` (or `ratingCount`) parses to ≥ 1. This is an optional enhancement — stores without reviews must NOT fabricate ratings (Google penalty). Coverage ≥ 60% across PDPs with Product JSON-LD passes; ≥ 30% partial; otherwise fail.

How to fix it

Add an AggregateRating to Product nodes when you have real reviews

Shopify

A few minutes
  1. Install a Shopify review app (Yotpo, Stamped, Judge.me, Loox, Okendo).
  2. Most apps inject AggregateRating JSON-LD automatically once they have one or more reviews.

BigCommerce

A few minutes
  1. Use BigCommerce's built-in Product Reviews or install Yotpo / Stamped.
  2. Confirm the review widget injects AggregateRating JSON-LD on PDPs.

WooCommerce

A few minutes
  1. Enable WooCommerce reviews under Products → Settings → Reviews.
  2. Yoast / RankMath emit AggregateRating from the WC review count.

Custom / headless

Developer
  1. Render `aggregateRating` from your review system's totals.
  2. Make sure ratingValue is in [0,5] and reviewCount is an integer ≥ 1.

The spec it's pinned to

  • schema.org/AggregateRating

    schema.org/AggregateRating requires `ratingValue` (0–5) and `reviewCount` (or `ratingCount`) ≥ 1. Agents use ratings to rank and filter products.
