> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.

> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

The following [Contact management objects](https://docs.kentico.com/k8/on-line-marketing-features/contact-management.md) can either be site-specific or global. Global objects are shared across all websites running in the system.
- [Contacts](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts.md)
- [Contact groups](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/contact-segmentation.md)
- [Contact statuses](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/assigning-statuses-to-contacts.md)
- [Accounts](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/organizing-contacts-into-accounts.md)
- [Account statuses](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/organizing-contacts-into-accounts.md)
- [Contact roles](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/organizing-contacts-into-accounts.md)
Global objects are disabled by default. To enable the use of global objects:
1. Open the **Settings** application.
2. Navigate to **On-line marketing -> Contact management -> Global data & merging**.
3. Adjust the following settings in the **Global data** section:
| Setting | Description |
| -------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Allow global contacts | Enables the use of global [contacts](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts.md) on the website. |
| Automatically create global contact for user | If enabled, the system creates new global contacts when it detects that there are multiple contacts associated with a user registered on multiple websites in the system.
The site-specific contacts are merged into the global contact.
If one of the detected contacts is already global, the system directly merges the other contacts into it instead of creating a new contact. |
| Automatically create global contact for visitors with identical e-mail addresses | If there are users with the same e-mail address across multiple websites, the system creates a global contact for all site contacts associated with the given user. |
| When choosing from global contacts, select | Indicates which contact the system uses as the primary contact for site visitors who have multiple global contacts assigned. The following options are available:
**Last modified** - the contact that was most recently modified.
**First created** - the oldest contact.
**Create a new contact** - the system creates a new contact and merges the other global contacts into it. |
| Allow global accounts | Enables the use of global [accounts](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/organizing-contacts-into-accounts.md) on the website. |
| Allow global contact groups | Enables the use of global [contact groups](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/contact-segmentation.md) on the website. |
| Allow global configuration | Enables the use of global [contact statuses](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/assigning-statuses-to-contacts.md), [account](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts/organizing-contacts-into-accounts.md) statuses and contact roles on the website. |
4. Click **Save**.
## User interface differences when global objects are enabled
If you allow global objects, the **Site** drop-down list becomes visible for site users above the list of objects in the **Contact management** application. The **Site** drop-down list offers the following options:
- **(global and this site)** - both global and the current site's objects
- **(global)** - only global objects
- **current site** - only the current site's objects
When you select **(global and this site)**, the grids show the **Site** column, which indicates if the object is site‑specific or global. You cannot create new objects with this option selected.
If you are a global administrator, the **Site** drop-down list is always present above the available tabs in the **Contact management** application.
