# Guard: what it checks and what it doesn't

Guard watches your product pages and checkout for things that get in the way of buying, like a broken add to cart button. It's in every plan. It helps you spot problems, but it's not a guarantee.

## What Guard checks
On product pages with the keyplace chat:
- keyplace disappears from the page or can't answer.
- Add to cart fails, or the page has no add to cart button.
- Script errors from your theme and app extensions.
- Slow pages: views that took over 4 seconds to load.

In your products in Shopify:
- price changes of over 50%,
- products with no variant in stock,
- an empty description, images or product type.

At checkout, for shoppers who allow analytics:
- how many shoppers get from the cart to checkout, payment and order,
- errors shown at checkout, for example with payment or delivery,
- app errors at checkout.

## Where you see it
1. In keyplace, open **Analytics**.
2. Click the **Reports** tab.
3. Click **Product page guard**.

Your weekly and monthly reports show the same data in **Product page health (Guard)**. The most urgent problems also show in **3 things to improve**.

## Limits
- Guard doesn't change your theme, apps or checkout. You decide on the fix.
- It doesn't place test orders and doesn't read orders or customer data. It only counts events.
- It watches product pages and checkout, not your home page or collection pages.
- Below about 30 chat views a day, keyplace doesn't flag a missing chat, because silence doesn't mean much yet.
- Some problems leave no signal, for example a button that does nothing and shows no error. A failed add to cart shows only in Chrome and other Chromium-based browsers.
- You see the **Product page guard** report once sales tracking works in your store.

## Common questions
### Do you email me when something breaks?
Not yet. Email alerts to you come in an update. Until then, alerts about a missing chat go to our team, and you see the rest in **Analytics** and in your reports.

### The app name in a checkout error looks odd. Why?
The shopper's browser reports the app name. Treat it as a hint, not a fact.

### Why don't the checkout numbers match Shopify?
Guard counts only shoppers who allow analytics. Shopify counts all orders.
