Product Reviews & Ratings

Overview

Product reviews are the strongest social proof signal in e-commerce — products with 5+ reviews convert at 270% higher rates than products with none. Every major platform has review apps that handle collection, moderation, schema.org markup for Google star ratings, and verified purchase badging without custom code. Only build a custom review system if you need proprietary moderation logic, deep API integration, or review data in your own database.

When to Use This Skill

• When launching a new store and needing a review collection and display system
• When implementing schema.org AggregateRating markup to enable star ratings in Google Search results
• When building a moderation workflow to prevent fake or spam reviews
• When displaying verified purchase badges to increase review credibility
• When triggering post-purchase review request emails automatically after delivery
• When importing reviews from one platform or app to another

Core Instructions

Step 1: Determine platform and choose the right review tool

Step 2: Platform-specific setup

Shopify

Option A: Judge.me (recommended — free, full-featured)

1. Install Judge.me Product Reviews from the Shopify App Store
2. Judge.me automatically sends a post-purchase review request email after a configurable delay:

- Go to Judge.me → Settings → Review Request Emails - Set delay to 5–7 days after fulfillment (gives customers time to receive and use the product) - Customize the email template with your brand colors and product images

1. Configure review display:

- Go to Judge.me → Widgets → Install Widgets - Enable the review widget on your product template (Judge.me provides a one-click install) - Enable the star rating snippet in product listings

1. Enable schema.org markup:

- Go to Judge.me → Settings → SEO - Ensure "Add aggregate rating schema" is enabled — this is what enables star ratings in Google search results

1. Configure verification and moderation:

- Go to Settings → Review Settings - Enable Verified Purchase Only: only customers who bought the product can leave a review - Enable Auto-publish verified reviews, manual moderation for unverified reviews - Set profanity filter to "Medium" or higher

Option B: Yotpo (mid-market and enterprise)

1. Install Yotpo Reviews from the App Store
2. Configure review request timing in Yotpo → Settings → Review Request
3. Enable Google Shopping Reviews syndication if you run Google Shopping campaigns — Yotpo sends review data directly to Google
4. Use Yotpo Q&A to add a question-and-answer section below reviews on the PDP

Testing schema.org markup: After enabling Judge.me or Yotpo schema output, validate with Google's Rich Results Test using your product page URL. Star ratings appear in Google Search within 1–2 weeks of indexing.

WooCommerce

WooCommerce built-in reviews (free, basic):

1. Go to WooCommerce → Settings → Products → Reviews
2. Enable Enable product reviews
3. Enable Show "verified owner" label on customer reviews — this restricts reviews to customers who purchased the product
4. Enable Reviews can only be left by "verified owners" to gate unverified submissions

Adding schema.org markup and enhanced display:

1. Install WP Product Review from the WordPress plugin directory
2. WP Product Review adds:

- Aggregate star rating schema.org markup (required for Google rich results) - Star rating display in product listings - Review pros/cons fields

1. Configure in WP Product Review → Settings

Automating review request emails:

1. Install Klaviyo or AutomateWoo for post-purchase email automation
2. In Klaviyo: create a Flow triggered by the "Placed Order" event with a 7-day delay, containing a review request link
3. In AutomateWoo: go to AutomateWoo → Workflows → Add → trigger: "Order Status Changed to Completed" with a 7-day delay

Judge.me for WooCommerce:

• Install Judge.me for WooCommerce (available at judge.me)
• Provides the same review request emails, verified purchase gating, and schema markup as the Shopify version

BigCommerce

Judge.me for BigCommerce:

1. Go to Apps → Search "Judge.me" and install
2. Same configuration as the Shopify version — review request emails, schema markup, and verified purchase gating work identically

BigCommerce built-in product reviews:

1. Go to Products → [Product] → Reviews tab to manually moderate reviews
2. Go to Settings → Store Settings → Miscellaneous → enable Product Reviews
3. Built-in reviews do not include schema.org markup — install Judge.me or Yotpo to get Google star ratings in search results

Yotpo for BigCommerce:

1. Install from the BigCommerce App Marketplace
2. Includes Google Shopping Reviews syndication and SMS review requests alongside email

Custom / Headless

For headless storefronts, build a review pipeline with post-purchase trigger, moderation, Bayesian aggregate scoring, and schema.org output:

// lib/reviews.ts

// POST /api/reviews — accept review submission with signed token verification
export async function submitReview(req: Request, res: Response) {
  const { token, productId, rating, title, body, authorName } = req.body;

  // Validate signed token (generated in post-purchase email, prevents spam)
  const tokenData = await verifyReviewToken(token);
  if (!tokenData) return res.status(401).json({ error: 'Invalid or expired review token' });

  const verifiedPurchase = await db.orderItems.exists({ orderId: tokenData.orderId, productId });

  // Auto-moderation: spam score + profanity check
  const spamScore = await checkSpam({ body, authorName, ip: req.ip });
  const hasProfanity = await checkProfanity(body + ' ' + title);

  const status =
    spamScore > 0.8 ? 'spam' :
    hasProfanity ? 'pending' :
    verifiedPurchase ? 'approved' : 'pending';

  const review = await db.reviews.create({
    productId, orderId: tokenData.orderId, customerId: tokenData.customerId,
    authorName, authorEmail: tokenData.email, rating, title, body,
    verifiedPurchase, status, approvedAt: status === 'approved' ? new Date() : null,
  });

  if (status === 'approved') await updateProductRatingSummary(productId);

  res.json({ reviewId: review.id, status });
}

// Bayesian aggregate: prevents a 2-review product with 5.0 outranking a 200-review product with 4.7
export async function updateProductRatingSummary(productId: string) {
  const reviews = await db.reviews.findMany({ where: { productId, status: 'approved' } });

  const rawAverage = reviews.length > 0
    ? reviews.reduce((sum, r) => sum + r.rating, 0) / reviews.length : 0;

  const globalMean = await db.reviews.globalAverageRating();
  const C = 5; // confidence weight — trust product's own average after 5+ reviews
  const bayesianAverage = (C * globalMean + reviews.reduce((s, r) => s + r.rating, 0)) / (C + reviews.length);

  await db.productRatingSummaries.upsert({ productId }, {
    productId, reviewCount: reviews.length,
    averageRating: Math.round(bayesianAverage * 10) / 10,
    rawAverageRating: Math.round(rawAverage * 10) / 10,
  });
}

// Emit schema.org AggregateRating JSON-LD — required for Google star ratings in search
export function buildProductSchema(product: Product, ratingSummary: { reviewCount: number; averageRating: number }) {
  return {
    '@context': 'https://schema.org',
    '@type': 'Product',
    name: product.name,
    image: product.images.map(i => i.url),
    description: product.description,
    sku: product.sku,
    offers: {
      '@type': 'Offer',
      price: (product.priceInCents / 100).toFixed(2),
      priceCurrency: 'USD',
      availability: product.inventoryQuantity > 0 ? 'https://schema.org/InStock' : 'https://schema.org/OutOfStock',
    },
    ...(ratingSummary.reviewCount > 0 && {
      aggregateRating: {
        '@type': 'AggregateRating',
        ratingValue: ratingSummary.averageRating.toFixed(1),
        reviewCount: ratingSummary.reviewCount,
        bestRating: '5',
        worstRating: '1',
      },
    }),
  };
}

// Trigger review request email 5 days after delivery
export async function triggerReviewRequest(orderId: string) {
  const order = await db.orders.findById(orderId, { include: ['lineItems.product', 'customer'] });
  const token = await createSignedReviewToken(orderId, order.customerEmail);

  await reviewQueue.add(
    'send-review-request',
    { orderId, email: order.customerEmail, token, products: order.lineItems.map(i => ({ productId: i.productId, name: i.product.name })) },
    { delay: 5 * 86400000, jobId: `review-request-${orderId}` }
  );
}

Step 3: Configure moderation workflow

All review apps need a moderation strategy before go-live:

In Judge.me:

• Go to Settings → Review Settings → Moderation
• Set verified reviews to auto-publish; unverified reviews to manual review queue
• Enable the profanity filter
• Check the moderation queue weekly at Judge.me → Reviews → Pending

In Yotpo:

• Go to Yotpo → Moderation → Settings
• Configure auto-approve rules (e.g., star rating ≥ 3 and verified purchase → auto-approve)
• Yotpo sends a daily moderation digest email to your configured team email

For custom builds: auto-approve verified purchase reviews that pass spam and profanity checks; queue all others. Never skip moderation entirely — process the pending queue daily.

Step 4: Measure review impact

Best Practices

• Use Judge.me or Yotpo before building from scratch — they handle schema markup, email timing, verified purchase logic, and moderation queues out of the box
• Send review requests 5–7 days after delivery, not after shipment — the customer needs time to receive and use the product
• Never delete negative reviews — suppressing them erodes trust and may violate FTC guidelines; respond to them publicly instead
• Show verified purchase badges — they increase review trust and help customers distinguish genuine reviews
• Cap carousels at 5–10 reviews on initial load — lazy load additional reviews to avoid blocking page LCP
• Validate schema.org markup with Google's Rich Results Test before launching — star ratings appear in search only when the JSON-LD is correct
