How to Use HubSpot to Target LinkedIn Ads with Synced Audiences

Using HubSpot to manage and sync audiences for your LinkedIn Ads allows you to run precise campaigns driven by real CRM data. This guide walks you through requirements, setup, syncing, and management so your LinkedIn advertising stays accurate and privacy-compliant.

What You Need Before Connecting HubSpot and LinkedIn

Before you can sync audiences between HubSpot and LinkedIn, confirm that your accounts and permissions are correctly configured.

HubSpot account and permissions

• You must be a Super Admin or have Ads Access permissions in HubSpot.
• You need permission to connect apps and edit ad settings inside your HubSpot account.

LinkedIn Ads requirements

• You must have a LinkedIn Ads account with an active Campaign Manager.
• You must have permission to manage matched audiences and edit campaigns.
• Your ad account must comply with LinkedIn advertising policies, including audience size thresholds.

How to Connect LinkedIn Ads to HubSpot

Once prerequisites are met, connect your ad account so HubSpot can sync audiences to LinkedIn.

1. In your HubSpot account, navigate to Marketing > Ads.
2. Click Connect account if you have not already connected LinkedIn Ads.
3. Select LinkedIn from the list of ad networks.
4. Log in to LinkedIn and authorize HubSpot to manage audiences and campaigns.
5. Confirm the correct LinkedIn Ads account is selected if you manage multiple accounts.

After the connection is complete, HubSpot can sync CRM-based audiences directly to LinkedIn Campaign Manager.

Types of HubSpot Audiences You Can Sync to LinkedIn

HubSpot can sync several different audience types to LinkedIn, helping you create targeted B2B segments at scale.

Contact list audiences in HubSpot

You can sync any eligible active list from HubSpot to LinkedIn as a matched audience, such as:

• Lifecycle stage lists (e.g., MQL, SQL, Opportunities)
• Engagement-based lists (e.g., opened emails, visited pricing page)
• Industry or persona-specific lists based on custom properties

Active lists are recommended so your LinkedIn audiences stay up to date as contacts meet or lose criteria in HubSpot.

Company list audiences in HubSpot

If you sell to accounts rather than individuals, you can sync company-based lists to LinkedIn for account targeting. Example use cases include:

• Targeting companies in a specific industry or region
• Focusing on high annual revenue or enterprise accounts
• Retargeting open deals from your HubSpot pipeline

Website visitor retargeting audiences

By installing the HubSpot tracking code and connected LinkedIn Insight Tag, you can build retargeting audiences of visitors who:

• Viewed specific product or pricing pages
• Started but did not complete a form
• Returned multiple times within a time window

These website-based audiences originate from tracking events in HubSpot and are pushed to LinkedIn for remarketing.

How to Create a LinkedIn Ads Audience from HubSpot

Once your integration is live, you can create synced audiences directly in the HubSpot ads tool.

Step-by-step: Create a HubSpot audience for LinkedIn

1. In HubSpot, go to Marketing > Ads.
2. Click the Audiences tab.
3. Select Create audience.
4. Choose the audience type, such as Contact list, Company list, or Website visitors.
5. Pick the specific HubSpot list or rule-based segment you want to sync.
6. Select LinkedIn Ads as the network destination.
7. Name your audience clearly (for example, “HubSpot – MQLs Last 90 Days – LinkedIn”).
8. Save the audience and allow time for the initial sync.

The first sync can take from several minutes to a few hours, depending on the size of the audience. HubSpot will then keep the list updated automatically.

How HubSpot Syncs Audiences with LinkedIn

Understanding how data flows between platforms helps you design compliant and reliable campaigns.

Data matching between HubSpot and LinkedIn

When a HubSpot audience is synced, the platform securely hashes and sends identifiers to LinkedIn, such as:

• Email addresses
• Company names or domains (for company audiences)
• Other matching fields supported by LinkedIn

LinkedIn compares these values to its member data to build a matched audience, which you can then target in LinkedIn Campaign Manager.

Automatic updates from HubSpot

After the first sync, HubSpot automatically:

• Adds new contacts or companies that meet audience criteria
• Removes members that no longer qualify for the audience
• Refreshes the list on a regular schedule so campaigns stay aligned with your CRM

This automation ensures that your LinkedIn Ads reflect current lifecycle stages, deal changes, and behavioral signals stored in HubSpot.

Minimum audience sizes on LinkedIn

LinkedIn enforces minimum audience sizes before your ads can serve. While exact thresholds can change, expect:

• A minimum number of matched members for contact list audiences
• A minimum number of companies for account-based audiences

If your HubSpot audience is too small, LinkedIn will show the audience as unavailable or limited until more members are matched.

Using HubSpot Audiences in LinkedIn Campaigns

After the sync is complete, you can use the new audience inside LinkedIn Campaign Manager.

Selecting HubSpot audiences in LinkedIn Ads

1. Open LinkedIn Campaign Manager.
2. Create a new campaign or edit an existing one.
3. In the audience section, choose Matched Audiences.
4. Search for the audience name you created in HubSpot.
5. Select that audience, then finalize your targeting, ad format, and budget.

Any future changes in HubSpot will keep feeding into this matched audience without manual uploads.

Best practices for combining HubSpot and LinkedIn targeting

• Start with a broad HubSpot segment, then add LinkedIn professional filters (job title, seniority, industry) to refine the reach.
• Exclude existing customers or open deals using additional HubSpot audiences to avoid wasting ad spend.
• Build separate audiences for awareness, consideration, and decision stages to align ads with lifecycle stages managed in HubSpot.

Monitoring Performance in HubSpot

The integration allows you to track linked performance metrics from your LinkedIn Ads directly inside HubSpot.

View campaign results in HubSpot

• Go to Marketing > Ads inside HubSpot.
• Use filters to view only LinkedIn campaigns tied to specific audiences.
• Review key metrics such as impressions, clicks, contacts created, and customers influenced.

By comparing multiple audiences, you can see which HubSpot segments generate the highest conversion rates and best return on ad spend.

Optimize audiences over time

Use performance data to refine your lists in HubSpot:

• Tighten or broaden list rules based on cost per lead and close rates.
• Clone winning audiences and adjust filters to test new variations.
• Align nurturing workflows in HubSpot with the messaging used in LinkedIn Ads.

Compliance and Privacy When Syncing from HubSpot

Because HubSpot connects sensitive CRM data with LinkedIn, you should prioritize compliance and user consent.

Consent management in HubSpot

• Ensure forms and subscriptions in HubSpot clearly state that data may be used for advertising.
• Use properties and lists to include only contacts that have granted the appropriate consent.
• Honor unsubscribe and data deletion requests before syncing audiences to LinkedIn.

Security considerations

Both platforms use secure hashing and encrypted connections, but you should also:

• Limit Ads Access permissions in HubSpot to trusted users.
• Review connected apps periodically.
• Follow your organization’s data governance policies for CRM and ad platforms.
