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

Link retargeting is one of the most underused growth tactics in digital marketing. It lets you show ads to people who clicked your shortened links — even when those links point to content you don't own, like news articles, industry blogs, or partner sites. If you've ever shared a great third-party article on social media and wished you could remarket to everyone who clicked, link retargeting is exactly the solution.

In this guide, you'll learn exactly how to set up link retargeting from scratch, which platforms to connect, how to build custom audiences, and how to structure your first campaign for maximum ROI.

What Is Link Retargeting?

Link retargeting is a marketing technique that adds a retargeting pixel to a shortened URL. When someone clicks the shortened link, the pixel drops a cookie in their browser, adding them to a custom audience you can later target with paid ads on platforms like Facebook, Instagram, LinkedIn, X, or TikTok.

Unlike traditional retargeting — which only works for visitors of your own website — link retargeting works with any URL you share, including third-party content. This dramatically expands the pool of people you can advertise to.

Why Link Retargeting Matters in 2026

• Larger audiences: Build ad audiences from content you don't own.
• Lower CPCs: Warm audiences typically convert 2-10x better than cold traffic.
• Content amplification: Every share becomes a lead-generation opportunity.
• Influencer & PR ROI: Capture value from press mentions and guest posts.

How Link Retargeting Works (The Technical Flow)

Before setting things up, it helps to understand the mechanics behind the scenes:

1. You create a short link (e.g., lunyb.com/xyz) that redirects to a target URL — this could be your site, a blog post, or a third-party article.
2. You attach one or more retargeting pixels (Facebook Pixel, LinkedIn Insight Tag, Google Ads tag, TikTok Pixel, etc.) to that short link.
3. When someone clicks the link, the browser briefly loads a redirect page that fires the pixel(s).
4. The pixel adds the visitor to a custom audience inside your ad platform.
5. You launch ads targeting that custom audience with a relevant offer.

The whole redirect happens in milliseconds — the user doesn't notice anything unusual, they just land on the destination page.

What You Need Before You Start

To set up link retargeting successfully, gather these assets first:

• A URL shortener that supports retargeting pixels (Lunyb, Rebrandly, Bitly, Replug, etc.)
• Active ad accounts on the platforms where you want to retarget
• Pixel IDs from each ad platform
• A list of URLs you plan to share (your own + third-party content)
• Landing pages and ad creative for the eventual retargeting campaigns

Step-by-Step: How to Set Up Link Retargeting

Step 1: Choose a Link Retargeting Platform

Not every URL shortener supports retargeting pixels. You need one that lets you inject third-party tracking scripts into the redirect flow. Popular choices include:

Platform	Retargeting Support	Free Plan	Best For
Lunyb	Yes	Yes	Marketers who want simple, privacy-respecting short links
Rebrandly	Yes (paid tiers)	Limited	Branded domains at scale
Replug	Yes	Trial only	Agencies running multi-pixel campaigns
Bitly	Enterprise only	Yes	Enterprise brands

Step 2: Install Pixels on Your Ad Platforms

Before you can add pixels to short links, they need to exist inside your ad accounts. Here's how to grab each pixel ID:

1. Facebook / Instagram (Meta Pixel): Go to Meta Events Manager → Data Sources → Add → Web → Meta Pixel. Copy the 15-16 digit Pixel ID.
2. LinkedIn Insight Tag: Campaign Manager → Analyze → Insight Tag → Install Manually. Copy the Partner ID.
3. Google Ads: Tools → Audience Manager → Your Data Sources → Google Ads Tag → copy the Conversion ID.
4. TikTok Pixel: Events Manager → Web Events → Manage → Set Up Web Events → copy the Pixel ID.
5. X (Twitter) Pixel: Ads Manager → Tools → Events Manager → create a new pixel and copy the ID.

Step 3: Add Your Pixel IDs to Your Shortener

Log in to your URL shortener and navigate to the retargeting or pixels section (naming varies). Add each pixel by:

1. Selecting the platform (Meta, LinkedIn, TikTok, etc.)
2. Pasting the Pixel ID
3. Naming the pixel clearly (e.g., "Meta - Main Brand")
4. Saving

Most platforms let you save multiple pixels so you can mix and match per campaign.

Step 4: Create a Retargeting-Enabled Short Link

Now you're ready to build your first retargeting link:

1. Click "Create Link" or the equivalent option in your dashboard.
2. Paste the destination URL (yours or a third-party article).
3. Choose a custom slug if desired (e.g., lunyb.com/industry-report).
4. In the pixel/retargeting section, select which pixels should fire on click.
5. Save the link and copy the shortened URL.

That link is now "pixel-loaded." Every click will add the visitor to your chosen custom audiences.

Step 5: Build Custom Audiences Inside Your Ad Platforms

Wait 24-48 hours after sharing your links so audience data begins populating. Then, inside each ad platform, create a custom audience based on website visitors filtered by the pixel that fired on your short-link redirect page.

For example, in Meta Ads Manager:

1. Audiences → Create Audience → Custom Audience → Website.
2. Choose the Pixel you set up.
3. Set condition: "People who visited specific web pages" and enter your shortener's redirect domain (or use "All website visitors" if the pixel is dedicated).
4. Set retention window (30, 60, 90, or 180 days).
5. Name and save the audience.

Step 6: Distribute Your Retargeting Links Widely

The bigger the click volume, the bigger the retargeting pool. Prioritize high-traffic channels:

• Organic social posts (LinkedIn, X, Facebook, Instagram bio links)
• Email newsletters
• Community shares (Reddit, Slack groups, Discord)
• Guest posts and press mentions
• Influencer collaborations
• QR codes on printed materials

A smart tactic: shorten third-party articles about your industry (Forbes pieces, TechCrunch coverage, viral news) and share them. You get to retarget people interested in your niche — for free.

Step 7: Launch Your Retargeting Ad Campaign

Once your audience reaches at least 1,000 people (Meta's minimum is 100, but 1,000+ performs better), create a campaign that speaks directly to their interest:

1. Select the custom audience built from your short-link clicks.
2. Match the ad creative to the topic they clicked (message-market fit).
3. Offer a clear next step: lead magnet, product demo, discount, or newsletter signup.
4. Start with a modest budget ($10-$25/day) and scale winners.

Best Practices for Link Retargeting Success

Segment Audiences by Topic

Instead of dumping every click into one audience, create separate short links (and audiences) per topic. Someone who clicked an article on "email marketing" should see different ads than someone who clicked "SEO tools."

Respect Privacy and Consent

Link retargeting uses cookies, so you must comply with GDPR, CCPA, and similar laws. Best practices:

• Disclose retargeting in your privacy policy.
• Only share links in contexts where users can reasonably expect tracking.
• Avoid retargeting sensitive topics (health, finance details, politics in some regions).

Use Branded Short Domains When Possible

Branded domains (like go.yourbrand.com) get higher click-through rates and feel more trustworthy than generic shorteners. Learn more in our honest review of Lunyb for one option that supports branded domains.

Refresh Content Regularly

Audiences decay quickly. Keep sharing new, click-worthy links every week to maintain a steady flow into your retargeting pool.

Common Mistakes to Avoid

• Not verifying pixels fire correctly: Use browser extensions like Meta Pixel Helper to confirm each pixel triggers on your short-link redirects.
• Retargeting too broadly: A single mega-audience wastes budget. Segment aggressively.
• Ignoring frequency caps: Showing the same ad 20 times a week annoys prospects.
• Skipping the offer: A retargeting ad without a strong CTA is a waste of pixel data.
• Mixing pixels for unrelated campaigns: Keep separate pixel setups for separate product lines.

Measuring Link Retargeting Performance

Track these KPIs weekly:

Metric	What It Tells You	Healthy Range
Click volume on short links	Audience growth rate	Depends on distribution scale
Audience size per pixel	Is the pool large enough to advertise?	1,000+ before launching
Retargeting CTR	Message-market fit	1-3% on Meta, 0.4-0.8% on LinkedIn
Cost per acquisition (CPA)	True ROI of the tactic	30-60% lower than cold traffic
Return on ad spend (ROAS)	Revenue efficiency	3x+ is a strong start

Advanced Tactics Once You're Comfortable

Stack Multiple Pixels on One Link

Attach Meta + LinkedIn + TikTok pixels to the same short link so you can retarget the same visitor across every major channel. This is especially powerful for B2B campaigns.

Build Lookalike Audiences

Once your retargeting audience reaches 1,000+ people, use it as a seed for lookalike (or "similar") audiences. This lets you prospect cold traffic that resembles your engaged clickers.

Integrate With Email and CRM

Send retargeting links inside email newsletters so subscribers who click get added to paid audiences too. This creates a powerful email + paid ad reinforcement loop.

A/B Test Destination Pages

Split traffic from the same short link between two landing page variants (via UTM parameters) and see which converts better. Compound wins over time.

Frequently Asked Questions

Is link retargeting legal?

Yes, when done in compliance with regional privacy laws like GDPR, CCPA, and ePrivacy. You must disclose tracking in your privacy policy and, in many regions, obtain consent through cookie banners on the destination pages. Never retarget in ways that violate ad platform policies (e.g., sensitive categories).

How many clicks do I need before launching a retargeting campaign?

Technically, Meta lets you run ads with as few as 100 people in a custom audience, but performance improves significantly at 1,000+. For LinkedIn, aim for 300+ matched members. Focus on distribution volume in the first 2-4 weeks before spending on ads.

Can I retarget clicks on links to other people's websites?

Yes — this is the core advantage of link retargeting. Because the pixel fires on the redirect page (which you control through the shortener), you don't need access to the destination site's code. Just remember: retargeting people who clicked a competitor's article works well; misleading them with irrelevant ads does not.

Does link retargeting work with iOS 14+ privacy changes?

It still works, but tracking is less precise. Apple's App Tracking Transparency and Intelligent Tracking Prevention reduce cookie lifetimes and opt-in rates. To adapt, combine link retargeting with server-side tracking, first-party data, and email-based audience uploads for better match rates.

How much does link retargeting cost?

The retargeting infrastructure itself is inexpensive — many URL shorteners offer pixel features on free or low-cost plans ($0-$29/month). The main cost is your ad spend. Start with $10-$25/day to validate, then scale winning campaigns based on ROAS.

Final Thoughts

Setting up link retargeting takes about 30 minutes but can transform how efficiently you spend on paid ads. By turning every shared link — including third-party content — into an audience-building asset, you dramatically expand your remarketing pool and reduce customer acquisition costs.

Start simple: pick one shortener, install one pixel, share five links this week, and launch your first retargeting campaign once you hit 1,000 audience members. From there, layer in more pixels, more segments, and more advanced tactics as you grow.
