# Guides

Guides for every place where example-petstore.com or example-commerce-host.com ends up in real sites and code, grouped by task: fixing site settings, developing and testing, security, and background.

## Fix your site settings

Analytics, structured data and Search Console settings copied from Google’s examples.

### [From Classic Analytics to Google Analytics 4](https://example-petstore.com/guides/google-analytics-cross-domain)

Remove `_setDomainName`, `_link` and `_linkByPost` code, install the Google tag, and set up cross-domain measurement and unwanted referrals the current way.

### [The sitelinks search box and site names](https://example-petstore.com/guides/sitelinks-search-box)

What the search box markup with `query.example-petstore.com` did, why Google dropped it, and the `WebSite` markup to use today.

### [Moving a site in Search Console](https://example-petstore.com/guides/change-of-address)

A complete site move with 301 redirects and the Change of Address tool, without example addresses in canonicals, sitemaps or `hreflang`.

## Develop and test

API clients, mock servers and example values that never reach a stranger’s server.

### [Configuring API clients and SDKs](https://example-petstore.com/guides/api-base-url)

Keep base URLs out of code, point them at the real service, and add a check that stops example addresses from reaching production.

### [Test against a mock API, not a placeholder](https://example-petstore.com/guides/mock-api)

Develop and test against Prism, WireMock, MSW or json-server instead of an address that belongs to someone else.

### [Looking for the Swagger Petstore?](https://example-petstore.com/guides/swagger-petstore)

The real base URLs of the Swagger Petstore sample API, working requests, the test key, and how to run your own copy with Docker.

### [Example values that are safe to use](https://example-petstore.com/guides/example-values)

Reserved domains, IP ranges, AS numbers, MAC addresses, phone numbers and test cards for examples that stay harmless.

## Security

When a key, token or password was sent here or committed to Git.

### [Leaked credentials: what to do now](https://example-petstore.com/guides/leaked-credentials)

Keys, tokens or passwords were sent to an example domain. Revoke and replace them, with direct links to the revocation pages of common providers.

### [Removing a secret from Git history](https://example-petstore.com/guides/remove-secrets-from-git)

A key was committed. Revoke it, remove it from the history with git-filter-repo, clean up GitHub and block the next leak.

## Background

Where the name comes from, which names are reserved, and the terms used on this site.

### [The history of example-petstore.com](https://example-petstore.com/history)

When and where Google used example-petstore.com and example-commerce-host.com, from 2009 to today, with archived sources.

### [Example domains](https://example-petstore.com/example-domains)

Which names are reserved for documentation, why look-alikes like this one get real traffic, and what to use instead.

### [Glossary](https://example-petstore.com/glossary)

Short explanations of `_setDomainName`, linker, `_gl`, unwanted referrals, SearchAction and 410 Gone.
