# **JSON-LD** Monitoring

Monitor structured data on live pages and get alerted the moment schema markup changes or disappears

## The markup that worked on **Tuesday** may not be there on Wednesday.

Validators are run at implementation, then again only when something makes you look. They confirm what was there then, not what's there now.

**Testomato monitors JSON-LD property values on live pages and alerts you the moment structured data changes or disappears.**

- #### Product

  price & name

- #### Organization

  identity & branding

- #### Ratings

  stars & review count

- #### Breadcrumbs

  navigation trail

- #### Instant

  alerts

## Why schema markup needs **monitoring**, not just validation

Schema markup reaches your pages through a pipeline: a CMS plugin, a template, a build step, a GTM tag. Any change can alter or remove the JSON-LD output without triggering a single error.

**By the time a Search Console report arrives, rankings are already affected.**

## Monitor the **structured data that matters most**:

- #### Product price & name

  A price mismatch between structured data and the visible page removes listings from Shopping results.

- #### Organization identity

  The name and URL in your Organization block feed your knowledge panel.

- #### Aggregate ratings

  Confirm your rating value always looks like a valid number, even as it changes over time.

- #### Breadcrumb trails

  A deploy can wipe breadcrumbs from SERP snippets with no visible sign on the page.

- #### Article metadata

  Publication date and author name affect how articles appear in search results.

- #### Presets for common schema fields

  Presets cover Product, Organization, Article, BreadcrumbList, and AggregateRating.

## Schema monitoring for **every site you manage**

JSON-LD doesn't render on the page, and most SEO tools aren't watching it continuously.

Adding structured data checks to a client project takes minutes. Testomato monitors the live page continuously and notifies you before it becomes a client conversation.

## Benefits of **JSON-LD monitoring**:

- #### Catch silent breaks immediately

  Know within five minutes when a plugin update, deploy, or CMS change alters or removes structured data.

- #### Protect rich result eligibility

  Keep Product schema valid so your pages stay eligible for product snippets and star ratings in Google Search.

- #### [Defend SEO performance](https://testomato.com/for-seo/)

  Rich result drops leave no trace in your logs. An incident timeline lets you correlate schema breaks with traffic changes.

- #### [Instant notifications](https://testomato.com/instant-alerts/)

  Alerts via Email, Slack, PagerDuty, Pushover, or Pushbullet the moment a check fails.

- #### Localized schema coverage

  Run separate checks for country or language variants. Catch cases where structured data differs across regions.

- #### 30-day incident history

  Every failure is logged with timing and response details. Trace exactly when a schema break started.

## JSON-LD monitoring FAQ

- What is JSON-LD monitoring?

  Checking that specific structured data properties exist and contain the expected values on a recurring schedule — not just once at implementation. Testomato verifies property values on live pages every five minutes and alerts you when anything changes or disappears. For a deeper look at why validation alone isn't enough, see our [guide to monitoring JSON-LD](https://testomato.com/blog/json-ld-monitoring/).

- How is this different from the Rich Results Test or a schema markup validator?

  Validators are on-demand — they check what's present when you run them. Testomato runs continuously and alerts you within minutes when something breaks.

- Which schema types does Testomato support?

  Presets cover Product, Article, Organization, BreadcrumbList, and AggregateRating — the schema types most likely to affect your search appearance.
