How to Publish a Text Banner Across Multiple SharePoint Online Sites
Question details
Organizations need a way to display the same text banner or announcement message concurrently across multiple SharePoint Online sites, covering both modern and classic site architectures.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Broadcasting a company-wide announcement or alert text banner to various site collections.
- Observed behavior
- A centralized method is required to push identical banners to multiple associated SharePoint sites rather than updating each site individually.
Verify whether your organization primarily uses modern or classic SharePoint sites, and ensure you have Site Admin or Hub Site Admin privileges before attempting to configure global announcements.
Use Hub Site News for Modern SharePoint Sites
The recommended approach for modern SharePoint sites is to utilize a Hub Site to syndicate News web part items acting as organizational banners.
Modern SharePoint architecture relies on Hub Sites to connect related sites. By publishing a news post acting as a banner on the Hub Site, it automatically rolls up to all associated sites without manual duplication.
Navigate to the SharePoint Admin Center, select 'Active sites', choose your primary communication site, and click 'Hub' > 'Register as hub site'.
For every modern site where you want the text banner to appear, go to 'Site Settings' > 'Site Information' and select the newly created Hub site from the 'Hub site association' dropdown.
On the associated sites' homepages, edit the page and add or modify the 'News' web part. Set the news source to 'All sites in the hub'.
Create and publish a News post on the main Hub site containing your text banner message. The announcement will now automatically display across the associated modern sites.
Implement SPFx Extensions or PowerShell for Classic Sites
Classic SharePoint sites lack native cross-site banner syndication and require custom scripting or development to achieve global messaging.

Frequently Asked Questions
Can I use the out-of-the-box SharePoint banner across multiple sites?
No, the standard 'Site Information' banner or site header customization is restricted to individual sites. You must use a Hub Site for modern pages or custom code for global syndication.
Does the News web part banner update in real-time on associated sites?
Once a news post is published on the main Hub site, it typically propagates to the associated sites' News web parts quickly, usually within a few minutes depending on Microsoft's server caching.
Will an SPFx Application Customizer work on modern SharePoint sites too?
Yes, an SPFx Application Customizer can place a persistent top-level text banner on both modern and classic sites, making it an excellent unified solution for hybrid SharePoint environments.
Do I need developer skills to create a banner for classic SharePoint sites?
Yes, since classic sites don't support native cross-site syndication like modern Hub sites, you will need developer knowledge to implement and deploy SPFx extensions or run PnP PowerShell scripts.
