How to Set Up Link Retargeting: A Complete Step-by-Step Guide

Link retargeting is one of the most underused yet powerful marketing techniques available today. If you've ever shared a third-party article, news story, or industry link on social media and wished you could reach those readers again with your own ads, link retargeting is the answer. This guide walks you through exactly how to set it up, from choosing a tool to launching your first campaign.

What Is Link Retargeting?

Link retargeting is a marketing technique that lets you add a retargeting pixel to any shortened link, so anyone who clicks that link is added to a custom audience you can advertise to later. Unlike traditional retargeting, which only works when visitors land on pages you own, link retargeting works even when you're sharing content from other websites.

For example, if you share a popular industry article on LinkedIn using a branded short link with a Facebook pixel attached, every person who clicks that link becomes someone you can later target with Facebook ads, even though they never visited your website.

Why Link Retargeting Matters

• Expand your audience: Build retargeting pools from third-party content, not just your own pages.
• Lower acquisition costs: Warm audiences convert at a fraction of the cost of cold traffic.
• Leverage trending content: Share viral news or research pieces to grow your audience quickly.
• Multi-platform reach: Attach pixels from multiple ad networks to a single short link.

What You Need Before Starting

Before you can set up link retargeting, make sure you have the following in place. Having these ready will save you hours of back-and-forth later.

1. A link shortener that supports retargeting pixels. Not all shorteners offer this feature. Popular options include Rebrandly, Bitly Enterprise, Lunyb, and RetargetLinks.
2. Active ad accounts on the platforms you want to target (Facebook/Meta, LinkedIn, X, Google Ads, TikTok, etc.).
3. Pixel IDs or tracking tags from each of those ad platforms.
4. A content strategy: a list of links you plan to share that align with your audience's interests.
5. A follow-up ad campaign ready to launch once you've built an audience.

Step 1: Choose the Right Link Shortener

Your choice of link shortener will shape your entire retargeting workflow. The ideal tool supports multiple pixel platforms, offers branded domains, provides analytics, and integrates with your existing marketing stack.

Step 2: Install Retargeting Pixels on Each Ad Platform

A retargeting pixel is a small snippet of code (or tracking ID) that ad platforms use to identify and track users. You'll need to create these pixels before you can attach them to short links.

Meta (Facebook & Instagram) Pixel

1. Go to Meta Events Manager.
2. Click Connect Data Sources and choose Web.
3. Select Meta Pixel, name it, and copy the 15-16 digit Pixel ID.

LinkedIn Insight Tag

1. In LinkedIn Campaign Manager, navigate to Analyze > Insight Tag.
2. Create a new tag and copy the Partner ID.

X (Twitter) Pixel

1. In X Ads Manager, go to Tools > Events Manager.
2. Create a website tag and note the Pixel ID.

Google Ads Remarketing Tag

1. In Google Ads, go to Tools > Audience Manager > Your Data Sources.
2. Set up the Google Ads tag and copy the Conversion ID.

TikTok Pixel

1. In TikTok Ads Manager, navigate to Assets > Events.
2. Create a web event and copy the Pixel ID.

Step 3: Add Pixels to Your Link Shortener

Once you have your pixel IDs, you need to register them inside your link shortener's dashboard so they can be attached to short links.

1. Log into your link shortener account.
2. Navigate to the Retargeting, Pixels, or Integrations section.
3. Click Add Pixel and choose the platform (Meta, LinkedIn, etc.).
4. Paste in the Pixel ID or Partner ID you collected in Step 2.
5. Give the pixel a clear label (e.g., "Meta - Main Account") so you can identify it later.
6. Save and repeat for each ad platform.

Most platforms let you attach multiple pixels to the same link, which means a single share can simultaneously feed retargeting audiences on Meta, LinkedIn, and X.

Step 4: Create a Retargeting-Enabled Short Link

Now it's time to create the actual link you'll share. The process typically takes under a minute.

1. In your shortener dashboard, click Create New Link.
2. Paste the destination URL (this can be your own site or any third-party article).
3. Choose your branded domain if available (e.g., yourbrand.co).
4. Customize the slug for readability (e.g., /industry-report-2026).
5. Under Retargeting Pixels, select which pixels to attach.
6. Click Create and copy the short link.

A good practice is to create a reusable "link template" that automatically attaches your default pixel set to every new link, so you never forget to tag a share.

Step 5: Share Links Strategically

Link retargeting only works if people actually click your links. The quality and relevance of what you share directly impacts the size and value of your audience.

High-Value Content to Share

• Industry research and reports that your target audience is actively searching for.
• Trending news in your niche, shared quickly to capture attention.
• Influencer interviews and podcasts that align with your buyer persona.
• Educational articles that solve a specific problem your product addresses.
• Case studies or data visualizations from reputable sources.

Where to Share

• Organic social media posts (LinkedIn, X, Facebook, Instagram bio).
• Email newsletters.
• Community platforms like Slack, Discord, and Reddit (where permitted).
• Guest posts and partner newsletters.
• QR codes on physical materials.

Step 6: Build Custom Audiences in Your Ad Platforms

Once links start getting clicks, your pixels will begin collecting audience data. The next step is turning that data into a usable audience.

Example: Creating a Custom Audience in Meta

1. Open Meta Ads Manager > Audiences.
2. Click Create Audience > Custom Audience > Website.
3. Choose the pixel you installed via your link shortener.
4. Set the rule to "People who visited specific web pages" and define a timeframe (30, 60, or 180 days).
5. Name the audience (e.g., "Link Retargeting - Industry Readers") and save.

Repeat similar steps on LinkedIn, X, Google, and TikTok. Most platforms require a minimum audience size (often 100-1,000 users) before you can start running ads to it, so give your campaigns time to accumulate clicks.

Step 7: Launch Your Retargeting Ad Campaign

Once your audience is populated, you can run ads tailored to the context of the link they clicked. This is where link retargeting delivers outsized ROI.

1. Create a new campaign in your ad platform.
2. Select the custom audience you built from your link clicks.
3. Craft ad creative that references the topic of the shared link (e.g., if you shared a report on cybersecurity trends, your ad should focus on your security solution).
4. Set a modest daily budget to start ($5-$20/day).
5. Monitor click-through rate, cost per click, and conversion rate after 7-14 days.

Best Practices for Link Retargeting

Match Ad Creative to the Shared Content

If someone clicked a link about remote work, don't retarget them with a generic brand ad. Instead, show them an offer that directly ties into remote work. Relevance is everything.

Use Branded Short Domains

Branded domains (like yourbrand.co/report) earn more clicks than generic ones because they feel trustworthy. Tools like Lunyb and Rebrandly support custom domains.

Respect Privacy Regulations

GDPR, CCPA, and other data protection laws apply to retargeting pixels. Make sure your website has a compliant cookie banner, your privacy policy mentions retargeting, and you only operate in jurisdictions where this is legally permitted.

Rotate Content Regularly

Don't rely on a single viral link. Share new content weekly to keep your audiences fresh and growing. Stale audiences lose effectiveness over time.

Segment Audiences by Link Topic

Attach different pixels or use different custom audience rules for different content categories. This lets you run laser-targeted campaigns for each segment.

Common Mistakes to Avoid

• Attaching pixels to irrelevant links. Only share content that attracts your actual target customer.
• Forgetting to test short links. Always click your own short link to confirm it redirects correctly and fires the pixel.
• Running ads too early. Wait until you have at least a few hundred users in your custom audience.
• Ignoring analytics. Review click data weekly to see which content drives the most audience growth.
• Breaking platform policies. Some ad networks restrict retargeting from third-party links; check each platform's rules.

Measuring Success

Track these key metrics to understand whether your link retargeting program is working:

• Click-through rate on shared short links.
• Audience growth rate in each custom audience.
• Cost per click (CPC) for retargeting ads compared to cold traffic.
• Conversion rate from retargeting campaigns.
• Return on ad spend (ROAS) compared to other acquisition channels.

In most cases, link-retargeted audiences convert 2-5x better than cold prospecting campaigns, making it one of the most cost-efficient tactics in modern digital marketing.

FAQ

Is link retargeting legal?

Yes, link retargeting is legal in most countries, but you must comply with regional privacy laws like GDPR (Europe), CCPA (California), and LGPD (Brazil). This typically means displaying a cookie notice, maintaining a privacy policy that discloses tracking, and honoring user opt-outs.

Do I need my own website to use link retargeting?

No. One of the biggest advantages of link retargeting is that it works even when you share links to content on other websites. However, you'll still need a destination (like a landing page or product page) for the ads you run to the retargeted audience.

How many clicks do I need before I can run retargeting ads?

Each ad platform has different minimums. Meta typically requires around 100 users, LinkedIn needs 300, and Google Ads needs 100 for display and 1,000 for search. Realistically, aim for at least 500-1,000 clicks before launching campaigns for statistical reliability.

Can I attach multiple pixels to one short link?

Yes. Most link retargeting platforms let you attach pixels from multiple ad networks to the same link. This way, one shared link can simultaneously build retargeting audiences on Meta, LinkedIn, X, and more, without extra work.

What's the difference between link retargeting and traditional retargeting?

Traditional retargeting only works for people who visit pages you own and control. Link retargeting works for anyone who clicks a short link you share, even if that link points to a third-party website. This dramatically expands the pool of people you can advertise to.

Final Thoughts

Setting up link retargeting is straightforward once you understand the moving parts: a capable link shortener, pixels installed across your ad platforms, and a thoughtful content-sharing strategy. The payoff is significant: you can build sizeable, engaged audiences without owning the content they came in through, then nurture them with highly relevant ad campaigns.

Start small with one or two pixels and a handful of high-quality links. Track your results, iterate on your content choices, and scale what works. Within a few months, link retargeting can become one of the most reliable, cost-effective channels in your marketing stack.
