![Tip](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/images/icon_tip.png) Tip Google Analytics is supported out-of-the box by Salesforce, and doesn’t require the following steps. However, before using Google Analytics, you must [configure it for your site](https://help.salesforce.com/s/articleView?id=experience.networks_google_analytics_setup.htm&release=264.0.0&type=5 "Set up Google Analytics to track user IDs, user types, and search activity so that users can pull this information into meaningful reports."). For security purposes, we restrict the tags, attributes, and values allowed in the `head` markup of your pages.
Allowed Tags Allowed Attributes
<base> href, target
<link>

as, charset, crossorigin, disabled, href, hreflang, id, import, integrity, media, rel,1 relList, rev, sheet, sizes, target, title, type

1 For rel, allowed values are alternate, apple-touch-icon, apple-touch-icon-precomposed, apple-touch-startup-image, author, bookmark, canonical, external, help, icon, license, manifest, mask-icon, next, nofollow, noopener, noreferrer, pingback, prefetch, preload, prev, search, shortcut icon, stylesheet, and tag.
<meta>

charset, content, http-equiv,2 name, property, scheme

2 For http-equiv, allowed values are cleartype, content-type, content-language, and default-style.

The attribute http-equiv="X-UA-Compatible" is only supported in combination with content="IE=Edge".

<noscript>

Within <noscript> only the following elements are supported: <a>, <iframe>, <img>, and <meta>3

3For <meta>, allowed attributes are http-equiv and content. Both attributes are required.

refresh is the only allowed value for the attribute http-equiv.

<script> Use for custom content
<style> type, media, nonce, title
<title> None allowed
If the content in your `` tag is invalid, you can’t save your work. If you entered unsupported code, hover over ![Code error indicator](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/builder_headererror.png) to see details on the issues. Existing `head` elements that contain invalid markup are stripped from the page before it’s rendered. To get the `head` working again, use Experience Builder to remove the unsupported tags. 1. In Experience Builder, click **![Settings](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_settings.png)** | **Advanced**. ![Advanced section of the Settings area in Experience Builder.](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_page_head2.png) 2. Click **Edit Head Markup**. 3. Enter the markup and save your changes. When you add custom markup, the code is added to the `head` of every page in your site, including login pages. 4. Before deploying the site to your production org, test the `head` markup in your sandbox or DE orgs. Depending on the CSP security level of your site, head markup sometimes doesn’t work as expected. See [Select the Relaxed CSP security level](https://help.salesforce.com/s/articleView?id=experience.networks_security_csp_tips.htm&release=264.0.0&type=5 "Whether you’re an administrator, content manager, or developer, be aware of the impact of the different security levels on your Experience Builder site. This impact can be far-ranging and unexpected."). Alternatively, conflicts can arise with Lightning Locker. See [Resolve Lightning Locker Conflicts in Experience Builder](https://developer.salesforce.com/docs/atlas.en-us.communities_dev.meta/communities_dev/communities_dev_security_limitations.htm) in the Experience Cloud Developer Guide. ![Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/images/icon_example.png) Example Here we added HTML to include a favicon on our site’s pages. ![Edit Head Markup dialog box](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_page_head1.png) #### See Also - [_Experience Cloud Developer Guide_: Example: Adobe Analytics and Lightning Locker in Experience Builder Sites](https://developer.salesforce.com/docs/atlas.en-us.communities_dev.meta/communities_dev/communities_dev_security_example.htm) - [_LWR Sites for Experience Cloud Developer Guide_: Head Markup in LWR Sites](https://developer.salesforce.com/docs/atlas.en-us.250.0.exp_cloud_lwr.meta/exp_cloud_lwr/template_differences_markup.htm)
