The custom domain feature allows ON24 customers to align their Engagement Hub URL to their corporate domain. Customers may utilize this feature for branding, SEO, and technical purposes.

Things to Know

Custom domain support is available in the ON24 Engagement Hub (Engagement Hub Enterprise). Customers interested in enabling this feature should contact their ON24 Account Manager. A custom domain can also be purchased as an add‑on.

Because custom domains require coordinated configuration between ON24 and customer teams, please allow sufficient time for setup and testing.

Customer Responsibilities

Setting up a custom domain requires collaboration between your IT/NetOps teams and ON24. Customers will need to:

Create a dedicated subdomain for each Engagement Hub (e.g., hub.customername.com).
Acquire and provide an SSL certificate for the custom domain.
If your organization uses Elite Webinars, we strongly encourage you to configure a matching custom domain for webinar Audience URLs. When combined with auto‑registration, attendees can seamlessly access the Engagement Hub directly without needing to register again through the Take Action tool.

Note: If Elite webinars are not enabled with the same custom domain, the auto-registration feature in the Take Action engagement tool will not work. They will have to register if they try to access the Engagement Hub.

Branding and User Experience

Once the custom domain is fully configured, you should match your brand styling from your website to the Engagement Hub to ensure a seamless user experience.

SEO will be properly attributed to your company’s domain rather than ON24’s once the custom domain is set up.

In addition, the URLs for any Target pages associated with the Hub will also display the custom domain.

SEO Benefits of Using a Custom Domain

Using a custom domain for your ON24 Engagement Hub provides several important SEO advantages:

Strengthens Brand Authority and Trust
- Search engines favor consistent branding. Hosting your Hub under your own domain (e.g., events.yourcompany.com) instead of on24.com/yourhub signals ownership and strengthens domain authority over time.
Consolidates SEO value to your site
- Inbound links to your Hub contribute to your website’s backlink profile, improving your overall SEO equity instead of benefiting ON24’s domain.
Improves Keyword Association
- Event titles, descriptions, and resource pages are indexed as part of your brand's domain, helping your content rank more effectively for your target keywords in search results.
Increases Click-Through Rates
- Users are more likely to click URLs that clearly belong to your brand, which can improve engagement metrics and, in turn, support higher search rankings.
Enhances Control Over Metadata and Tracking
- A custom domain helps align meta tags, structured data, and analytics tracking, helping search engines see your Hub as part of your main site’s architecture.

Custom Domain Process - Initial Setup

Step (Party)	Step (Description)
0 (Client & ON24)	Reach out to your CSM or Solutions Consultant to express your interest in setting up a custom domain.
1 (Client)	Acquire a subdomain for products to be configured: one for each Engagement Hub URL (e.g. , hub.customername.com) and one for Elite Webinars (e.g., events.customername.com).
2 (Client)	Submit a case to Platform Support to request the creation of a certificate for the domain to be used (e.g., hub.customername.com). Copy your CSM and Solutions Consultant (if applicable) on the case and include the information below to support the desired type of SSL Certificate. ON24 will generate the certificate on your behalf. Common name (If SAN SSL) List all subdomains to be covered (If single-domain SSL) List the domain name to be covered Division (e.g., NetOps, Marketing) Organization      Locality (the city where the business resides) Search Console State or Province             Country E-mail address
3 (Client)*	Client submits a site map to search engines (Google search console). Please note that to submit the sitemap, you must complete the site verification with the Domain name provider option: https://support.google.com/webmasters/answer/9008080?hl=en Engagement Hub site maps can be copied from the “Overview” tab within the platform.
4 (Client)	Add DNS CNAME entries that would point Engagement Hub domains to ON24 Virtual Servers. Examples: NA datacenter - \| & Target URLs will be displayed and published to end users via the custom domain, and you will be able to use the full breadth of \| hub.customername.com >> gatewaywhitelabel.on24.com events.customername.com >> eventwhitelabel.on24.com EU datacenter - hub.customername.com >> gatewaywhitelabel.eu.on24.com events.customername.com >> eventwhitelabel.eu.on24.com
5 (ON24)	ON24 installs an SSL certificate for the requested custom domains.
6 (ON24)	ON24 configures all Engagement Hubs & Target instances in the ON24 platform to use the desired custom domain (e.g. hub.customername.com ).
7 (N/A)	With this setup in place, Engagement Hub & Target URLs will be displayed  and published to end-users using the custom domain, and you will be able to use the full breadth of the features available in Engagement Hub and Target. Example of final custom URL: hub.customername.com/wcc/eh/3134332/knowledge-hub-name Please note that this part of the URL (including Hub ID and name) "/wcc/eh/3134332/knowledge-hub-name" is required.
8 (Client)	Client must inform IT/Security teams to EXCLUDE each configured Custom Domain from any security scanning, vulnerability testing, bug bounties, web crawling, or other similar activities. Failing to create these exclusions could result in ToS violations and potential service disruptions to Client.
9 (Client & ON24)*	Enable “Allow search engines to crawl/index” via toggle on your Engagement Hub Overview tab. With this, ON24 will dynamically construct and maintain sitemap_<customer-domain>.xml of all content across Engagement Hubs & Target pages, and the sitemap can be copied from the Overview tab.
10 (ON24)*	ON24 handles robots.txt file mapping.
11 (N/A)*	Search engines will crawl the sitemap and index its content pages. Please note that search results ranking depends on various factors and is beyond ON24's control.

*Steps 3, 9-11 are specific to using a the |custom domain for SEO and do not necessarily have to be done if the Engagement Hub won’t be indexed by search engines.

Custom Domain Process - Renewal (Annual)

Note: You may need to renew your domain name. ON24 automates the SSL renewal.
