# Manage my Subdomain with AB Tasty Tag

When implementing tags, it's possible to restrict their execution to specific subdomains. This ensures that tags will only function on designated subdomains and not on others.

\
S**ubdomain Restriction Examples**

* Top domain Execution: If you set the tag to "my-website.com," it will execute on all my-website.com subdomain, including eshop.my-website.com and blog.my-website.com. 
* Specific Subdomain Execution: Setting the tag to "eshop.my-website.com" will restrict its execution to the "eshop" subdomain. It will not execute on blog.my-website.com.

**Good to know:** 

* Cookie Domain Restriction: If you apply subdomain restrictions due to multiple AB Tasty accounts across different subdomains, ensure your [cookie domain settings](https://app2.abtasty.com/settings/cookies-privacy/advanced-cookies-settings) are updated accordingly.
* Multiple Domains: For business purposes requiring more than one domain per account, contact your usual AB Tasty representative to discuss your needs and request additional domains.

**Execution Behavior**

If a tag is implemented on a domain not listed, it will not execute on any unlisted domains or excluded subdomains. This ensures no unintended effects on those domains.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.abtasty.com/account/tag-integration/implement-ab-tasty-tag/manage-my-subdomain-with-ab-tasty-tag.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
