Google Rich Snippets adds each product's rating to its product page as structured data, so Google can show star ratings next to the page in search results. Google decides whether, and when, it shows them.

Navigate to [Settings → Syndication → Google Rich Snippets](https://app.cevoid.com/settings/syndication/google-rich-snippets) to manage Google Rich Snippets.

## How Google Rich Snippets works

Google Rich Snippets is off until you turn it on. Then Cevoid adds Product structured data with an AggregateRating to your product pages: the product's average rating, from 1 to 5, and its number of ratings, star-only ratings included. Individual reviews aren't part of it, and company reviews never add structured data.

| Platform | How the rating reaches the page |
| --- | --- |
| Shopify | Cevoid writes each product's rating and number of ratings to Shopify's standard product rating metafields. The **Product rating** block of the Cevoid: Reviews Platform app puts the stars and the structured data in the page's HTML |
| Other platforms | A **Dynamic Product Rating** widget, or a product page review list that shows its rating summary, adds the structured data in the shopper's browser. A developer can also render it on your server |

Google reads structured data in the page's HTML more reliably than structured data added with JavaScript.

Cevoid adds no structured data for a product with no ratings, and none from sample reviews. In the browser, it also adds none when the page already has rating structured data for the product, such as from your theme, or when more than one product shows a rating on the page, such as on a collection page.

## Turn on Google Rich Snippets

Turn on Google Rich Snippets once for your workspace. On Shopify, Cevoid asks you to authorize it to write ratings to each store that has the Reviews app.

1. Navigate to [Settings → Syndication → Google Rich Snippets](https://app.cevoid.com/settings/syndication/google-rich-snippets)
2. Enable **Enable Google Rich Snippets**
3. Click **Save changes**
4. Click **Authorize and enable**, if _Authorize Shopify review aggregate ownership_ opens

Authorizing lets Cevoid write each product's rating and number of ratings to Shopify's standard product rating metafields, replacing the values there, such as a previous review app's. Each store is filled on its own: see [Shopify storefronts](https://docs.cevoid.com/reviews/showcase/google-rich-snippets#shopify-storefronts). Then, on Shopify, add the **Product rating** block: see [Add the Product rating block on Shopify](https://docs.cevoid.com/reviews/showcase/google-rich-snippets#add-the-product-rating-block-on-shopify).

If Cevoid pauses delivery for every workspace, the page shows _Delivery temporarily paused_. Your setting is kept, but Cevoid adds no structured data until delivery resumes.

## Add the Product rating block on Shopify

On Shopify, the **Product rating** block puts the rating and its structured data in your product pages' HTML. Add exactly one to your product template. The **Product reviews** block never adds structured data.

1. Navigate to [Settings → Syndication → Google Rich Snippets](https://app.cevoid.com/settings/syndication/google-rich-snippets) and click **Open theme editor** next to your store under _Storefronts_. The Shopify theme editor opens on your product template.
2. Click **Add block** in the product's main section
3. Search for `Cevoid` and select **Product rating**
4. Optional: Paste the ID of a **Dynamic Product Rating** widget in _Widget ID (optional)_
5. Click **Save**

Without a widget ID, the block shows the rating from the metafields, such as _★ 4.8 (128 ratings)_. With one, the widget's stars replace it once they load. Before you authorize the store, the block shows the rating already in those metafields, such as a previous review app's, and adds no structured data. To add the block from a widget instead, see [Embed review widgets](https://docs.cevoid.com/reviews/showcase/embed-review-widgets.md).

## Rich snippets on other platforms

On platforms other than Shopify, your review widgets add the structured data once Google Rich Snippets is on. Add a **Dynamic Product Rating** widget, or a **Dynamic Product Reviews** widget that shows its rating summary, to your product pages: see [Embed review widgets](https://docs.cevoid.com/reviews/showcase/embed-review-widgets.md).

The widget adds the structured data with JavaScript, so the market health check rates the page _Best effort_. To put the rating and structured data in the page's HTML instead, a developer can render them on your server with Cevoid's Storefront API.

## Shopify storefronts

On Shopify, _Storefronts_ on [Settings → Syndication → Google Rich Snippets](https://app.cevoid.com/settings/syndication/google-rich-snippets) lists each connected store that has the Reviews app. Each store progresses on its own, and connecting a store never authorizes Cevoid to write to it.

| Status | What it means |
| --- | --- |
| _Confirmation required_ | Cevoid isn't authorized to write this store's ratings yet. Click **Authorize** |
| _Waiting_ | The store is queued to be filled |
| _In progress_ | Cevoid is writing the store's ratings. _Latest check_ shows how many products are done |
| _Completed_ | Every product's rating is written |
| _Failed_ | Writing the ratings failed. Click **Retry** |
| _Ready_ | The store is authorized, with nothing in progress |

_Restored_ shows when Cevoid restored its authorization after the Reviews app was reinstalled. **Open theme editor** opens the store's product template in the Shopify theme editor.

After authorization, Cevoid updates a product's metafields as its ratings change, and checks every store's values each hour. If another app overwrites them, the hourly check restores Cevoid's values, and the market health check shows _Shopify aggregate values were overwritten_.

## Check your market health

_Market health_, on the Google Rich Snippets page, checks a sample of live product pages in each market for the rating and its structured data. It checks your pages, not Google's index. Cevoid runs it once a day while Google Rich Snippets is on, and when you click **Run check**.

1. Navigate to [Settings → Syndication → Google Rich Snippets](https://app.cevoid.com/settings/syndication/google-rich-snippets)
2. Click **Run check** under _Market health_
3. Click **View** next to a market's findings. _Findings and remediation_ opens.
4. Optional: Click **Rich Results Test** next to a page to test it in Google's tool

In each market, the check visits up to 3 product pages with ratings: the one with the most ratings, the most recently updated one, and one that changes every day.

| Status | What it means |
| --- | --- |
| _Healthy_ | The checked pages have the rating and its structured data in their HTML |
| _Best effort_ | The structured data is added with JavaScript only |
| _Needs attention_ | A checked page has a finding to fix |
| _Checking_ | The check is running |
| _Not checked_ | The market hasn't been checked yet |

| Finding | What to do |
| --- | --- |
| _Rendered with JavaScript only_ | Use the Shopify **Product rating** block, or render the structured data on your server |
| _Product rating owner block missing_ | Add exactly one **Product rating** block to the active product template |
| _Visible rating missing_ | Repair the **Product rating** block or its widget. If another source adds the structured data, show a matching rating on the page |
| _Duplicate rating schema_, _Conflicting rating schema_ | Remove or turn off the other source of rating structured data. If you keep an SEO app that adds it from Shopify's standard review metafields, turn off Google Rich Snippets instead |
| _Shopify aggregate values were overwritten_ | Turn off the other review integration. Cevoid has restored its values |
| _Invalid product schema_ | Fix or turn off the source of the invalid structured data. Cevoid never changes your theme files |
| _Schema points to another product_ | Remove or correct the other source, so it names this product page |
| _Page could not be crawled_ | Make the product page public, indexable, and reachable without a login or a redirect to another domain |
| _Check was inconclusive_ | Remove consent or login barriers for crawlers, then run the check again |

Findings show on this page and as the status of Google Rich Snippets on [Settings → Syndication](https://app.cevoid.com/settings/syndication), such as _On · Healthy_ or _On · Needs attention_. Cevoid doesn't email them.

## Turn off Google Rich Snippets

Turn off Google Rich Snippets to stop Cevoid adding rating structured data to your product pages.

1. Navigate to [Settings → Syndication → Google Rich Snippets](https://app.cevoid.com/settings/syndication/google-rich-snippets)
2. Disable **Enable Google Rich Snippets**
3. Click **Save changes**

On Shopify, Cevoid keeps your stores' rating metafields up to date, so the **Product rating** block still shows the stars.
