How to Embed Calls-to-Action on External Sites with Hubspot

Using Hubspot, you can embed calls-to-action (CTAs) on external websites to capture leads, track engagement, and drive conversions beyond your main site. This guide explains the available embed options, how to configure them, and what to check when CTAs do not appear correctly.

Understanding Hubspot CTA embed options

When you create a CTA, Hubspot provides different ways to place it on external pages. Each method fits a specific use case and level of technical control.

Standard JavaScript embed from Hubspot

The default method for modern button CTAs is a JavaScript embed code. This script dynamically loads your CTA and lets the platform track views and clicks.

• Supports design and content changes from the tool without re‑embedding
• Automatically pulls the latest CTA version
• Enables full tracking and reporting inside your account

This option is recommended whenever the external page supports JavaScript and you want the most accurate analytics.

Image embed method from Hubspot

For environments that restrict JavaScript, such as some email templates or legacy site builders, Hubspot also offers an image embed:

• Generates a static image of your CTA button
• Provides a destination URL to link the image
• Offers basic click tracking, but fewer dynamic capabilities

Use this approach when you cannot insert script tags, but still want a visual CTA that directs visitors to a landing page or form.

Preparing your site to host Hubspot CTAs

Before embedding, confirm that the external site is technically ready to host Hubspot-generated code. A few checks can prevent display or tracking problems.

Confirm access level and editing method

Determine how you will add the CTA code:

• Directly in the HTML of a page template
• Through a CMS block or widget that accepts code
• Using a tag manager that injects scripts where needed

For consistent results, avoid placing CTA embed code in areas that strip or escape script tags, such as rich text fields that only allow basic formatting.

Check JavaScript and security settings

Many external sites use security filters that can block scripts or external resources. Review:

• Content security policies that might block the script domain
• Ad blockers or privacy tools that may hide marketing scripts
• HTTPS settings to avoid mixed-content issues when loading resources

If the CTA does not appear, inspect the browser console for blocked resources or script errors related to Hubspot.

How to embed a Hubspot CTA on an external page

Follow these steps inside your portal and then on your external site to add the CTA correctly.

Step 1: Locate your CTA in Hubspot

1. Sign in to your account.
2. Navigate to the marketing section where CTAs are managed.
3. Find the CTA you want to place externally and open its details screen.

From this screen, you can view summary metrics, edit the design, and access the embed options.

Step 2: Copy the JavaScript embed code

1. In the CTA details, look for the option to embed or share.
2. Select the JavaScript embed option.
3. Copy the full script snippet exactly as provided, including opening and closing tags.

Do not modify parameters inside the script unless you are following specific advanced instructions, as changes can break rendering or tracking.

Step 3: Paste the code into your external site

1. Open the page or template in your external CMS or editor.
2. Switch to an HTML or code view that allows script tags.
3. Paste the script where you want the CTA to appear, such as within the main content area or a sidebar block.
4. Save or publish the changes.

After publishing, visit the page in a browser, clear cache if needed, and check that the CTA loads as expected.

Alternative: Use image embed from Hubspot

If the external system does not support scripts, use the image embed instead:

1. In the CTA details, choose the image embed option.
2. Copy the generated image code or download the image asset.
3. Insert the image into your external page or template.
4. Link the image to the CTA target URL, such as a landing page or form.

This keeps the visual appearance of the CTA while bypassing script restrictions.

Testing and troubleshooting Hubspot CTA embeds

Once embedded, you should test both the display and the analytics to confirm that everything works correctly on your external site.

Check CTA display on the page

• Load the page in an incognito or private window.
• Disable browser extensions that may block scripts or images.
• Test on both desktop and mobile devices.

If the CTA does not load, view the page source and confirm that the embed code appears unaltered and in the correct location.

Verify tracking and performance in Hubspot

After visitors start seeing and clicking the CTA, review metrics inside your portal:

• Views to confirm the external page is sending impressions
• Clicks to track engagement from the external audience
• Submission or conversion rates if the CTA points to a form

If data does not appear, ensure that the correct CTA is embedded and that no caching layer is serving outdated or stripped versions of the code.

Best practices for managing Hubspot CTAs on external sites

Embedding CTAs beyond your main domain expands your reach, but it also requires structured management to stay organized and effective.

Keep a record of where each CTA is embedded

Create a simple inventory that maps each CTA to the external pages where it is placed. Track:

• Domain and URL for each placement
• Purpose of the CTA on that page
• Date of last update or design change

This makes it easier to adjust messaging or retire outdated offers while keeping your external placements aligned with your core strategy.

Coordinate design consistency inside Hubspot

Use centralized styling and templates so CTAs embedded on partner or microsites still reflect your brand. When you update a CTA design within the tool, the JavaScript embed automatically pushes the change to every external page using that code.

Review source documentation for Hubspot CTAs

For detailed, product-specific behavior and edge cases such as script loading order or compatibility considerations, consult the official documentation provided at this Hubspot CTA embed resource. It outlines the latest interface options, screenshots, and any recent changes to the process.

Next steps and additional Hubspot resources
