Announcement Bar Plugins for Squarespace — Highlight Key Messages & Drive Engagement
Announcement Bar Plugins for Squarespace let you display prominent, eye-catching notification banners or strips across your website — perfect for promoting sales, updates, events, free offers, new products, newsletter sign-ups, urgent alerts, or clickable calls to action. Squarespace includes a basic built-in announcement bar feature (especially on Business/Commerce plans), but third-party announcement bar widgets add more customization, visual styles, triggers, and layout options that make your message even more effective. bigcatcreative.com +1
Squarespace doesn’t use a WordPress-style plugin marketplace, so announcement bar tools are usually external widgets you build online and embed via a Code Block or Settings → Advanced → Code Injection. These can include floating banners, dynamic messages, sticky notification panels, and more.

Manual In-Site Announcement Bar (Built-In Squarespace Tool)
If you don’t need an external widget, Squarespace’s own announcement bar feature lets you add a simple banner across your site through the dashboard. You can show a text message with an optional link, choose basic styling, and place it at the top of every page. bigcatcreative.com +1
Where to Find It in Squarespace:
- Go to Marketing → Marketing Tools → Announcement Bar
- Enable the bar, add your message and optional link
Customize colors, fonts, and styles in the Design/Style settings (if your plan allows) Note: This built-in bar works best for basic site-wide messages and doesn’t include advanced widget features like buttons, animations, or per-page display controls. bigcatcreative.com
When to Use an Announcement Bar
Promote Limited-Time Offers — Highlight flash sales or discount codes Share Important Updates — Site changes, new product launches, shipping alerts
Drive Traffic — Link directly to landing or collection pages
Collect Leads — Encourage newsletter sign-ups or downloads
Boost Conversions — Add strong CTAs that guide user actions
These banners are especially valuable because they’re visible on every page and unobtrusive compared to pop-ups, yet they grab attention right away. bigcatcreative.com
How to Add an Announcement Bar to Squarespace
Choose a widget or tool (e.g., Elfsight, Common Ninja).
Build your announcement bar in the provider’s online dashboard — set text, colors, buttons, and behavior.
Copy the embed code the tool provides.
In Squarespace, open the page where you want it to appear.
Add a Code Block or go to Settings → Advanced → Code Injection.
Paste the embed code and save.
Preview on desktop and mobile to ensure visibility and responsiveness.
Using a Code Block lets you place the announcement bar in any page or section, while Code Injection allows site-wide placement. This gives you flexible control beyond the default Squarespace announcement tool.
