Website Retargeting Setup

What AdGradr checks

AdGradr verifies whether accounts with an active LinkedIn Insight Tag have created website retargeting audiences in Campaign Manager. It flags accounts where the Insight Tag is present but no retargeting audiences have been created as the most significant finding. Accounts with only an unsegmented “all visitors” audience receive a moderate flag. Audiences that exist but fall below LinkedIn’s minimum member threshold receive a minor note.

Why this matters

The LinkedIn Insight Tag does two things: tracks conversions and builds retargeting audiences. Most advertisers install it for conversion tracking and stop there. They never go into Campaign Manager to create the retargeting audiences that turn website visitors into targetable segments.

This is a significant missed opportunity. Website visitors already know your brand. They visited your site, read your content, or browsed your product pages. Retargeting these people on LinkedIn costs less per conversion than cold targeting because the intent signal already exists.

But the audiences do not build themselves. Unlike some platforms where retargeting audiences populate automatically, LinkedIn requires you to explicitly define which URL patterns or page groups constitute an audience. If you skip this step, the Insight Tag collects data that goes nowhere.

What good looks like

A properly configured account has multiple website retargeting audiences segmented by intent level:

• All website visitors (broad retargeting pool, 180-day window).
• Key page visitors (pricing page, demo page, product pages) with shorter windows (30 to 90 days) to capture higher-intent traffic.
• Converters (thank you page visitors or form submitters) used as an exclusion list so you do not retarget people who already converted.
• Each audience has 300+ members so LinkedIn can actually deliver ads against it.
• Audience windows match the sales cycle. A 30-day window works for transactional products; 90 to 180 days is better for enterprise sales.

Common mistakes

1. Installing the tag and assuming retargeting is set up. The tag enables retargeting. It does not create the audiences. That is a separate step in Campaign Manager under Matched Audiences.
2. Creating only an “all visitors” audience. This lumps blog readers with pricing page visitors. The intent signals are completely different, and your ad creative should reflect that.
3. Setting audience windows too short for the sales cycle. A 30-day window on an enterprise product with a 6-month sales cycle means you lose most of your retargeting pool before they are ready to buy.
4. Not checking audience size. LinkedIn requires a minimum of 300 matched members to serve ads. If your website traffic is low, it may take weeks or months to build audiences above this threshold.

How to fix it

1. Go to Campaign Manager > Plan > Audiences > Create Audience > Website.
2. Create a broad “All Visitors” audience with a 180-day lookback window.
3. Create at least two intent-based segments: one for high-value pages (pricing, demo, product) with a 90-day window, and one for content pages (blog, resources) with a 180-day window.
4. Create a “Converters” audience from thank-you page URLs. Use this as an exclusion in your retargeting campaigns.
5. Check audience sizes after 2 to 4 weeks. If they remain under 300, your website traffic may be too low for LinkedIn retargeting to work yet. Focus on driving traffic first.
6. Build campaigns against each audience with creative that matches their intent level.

When to ignore this check

Accounts with very low website traffic (under a few hundred monthly visitors) may not build audiences above the 300-member minimum regardless of configuration. In that case, the priority is driving traffic first, not configuring retargeting. The check also does not apply to accounts that exclusively use LinkedIn for brand awareness with no website in the funnel.
