> **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).

| Enable on-line marketing | Indicates if on-line marketing should be enabled. This includes the following functionality:
Tracking of users on the live site as [contacts](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/working-with-contacts.md). If the setting is disabled, users can still work with existing contacts in the administration interface.
Logging of on-line marketing [activities](https://docs.kentico.com/k8/on-line-marketing-features/contact-management/tracking-contact-activities.md).
[Newsletter](https://docs.kentico.com/k8/on-line-marketing-features/e-mail-marketing/working-with-newsletters.md) marketing features, i.e. e-mail tracking, A/B testing and bounced mail monitoring. |
| Optimization | |
| Enable A/B testing | Indicates if [A/B testing](https://docs.kentico.com/k8/on-line-marketing-features/optimization-testing/a-b-testing-website-pages.md) is allowed for pages (documents).
A/B testing allows you to define different variants of pages. When a visitor views the tested page on the live site for the first time, the system randomly displays one of the variants. From that point, the visitor's activity on the website is logged and categorized under the given variant.
In order to work correctly, A/B testing additionally requires the **Enable web analytics** and **Track conversions** settings to be enabled in **Settings -> On-line marketing -> Web analytics**. |
| Enable multivariate testing | Indicates if [multivariate testing](https://docs.kentico.com/k8/on-line-marketing-features/optimization-testing/multivariate-testing.md) (MVT) is enabled. This allows you to define MVT tests for pages and create different variants of their content. Once the test is running, the system assigns one of the possible content combinations to visitors who access the page on the live site. From that point, the visitor's activity on the website is logged and categorized under the given MVT combination.
In order to work correctly, multivariate testing additionally requires the **Enable web analytics** and **Track conversions** settings to be enabled in **Settings -> On-line marketing -> Web analytics**. |
| Content personalization | |
| Enable content personalization | Indicates if [content personalization](https://docs.kentico.com/k8/on-line-marketing-features/content-personalization.md) is enabled. This allows page designers (and content editors) to create different variants of web parts, entire web part zones or editor widgets. The system displays the variants to users on the live site according to dynamically resolved conditions. |
