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

Link retargeting is one of the most underrated growth tactics in modern marketing. Every time you share a link — to a news article, a partner blog, an industry report, or a YouTube video — you're sending traffic somewhere, but rarely capturing any of it. Link retargeting flips that script. It lets you drop a tracking pixel on anyone who clicks your shared links, even when those links point to websites you don't own.

In this guide, you'll learn exactly how to set up link retargeting from scratch, which platforms to use, how to structure your audiences, and how to launch your first remarketing campaign without wasting ad spend.

What Is Link Retargeting?

Link retargeting is a marketing technique that allows you to add retargeting pixels to shortened links, so any user who clicks the link is added to a custom advertising audience. Unlike traditional retargeting — which only works for visitors of your own website — link retargeting works on third-party content.

For example, if you share a Forbes article about your industry on Twitter using a shortened, pixel-enabled link, every person who clicks that link can later be retargeted with your ads on Facebook, Instagram, Google, LinkedIn, or TikTok. The user visits Forbes, but you build the audience.

Why Link Retargeting Works

• You leverage other people's content to grow your audience pool.
• You capture engaged users — people who clicked, not just scrolled past.
• You scale your retargeting list faster than relying on site traffic alone.
• You stay top-of-mind by following up with relevant offers.

How Link Retargeting Works (The Mechanics)

Behind the scenes, link retargeting uses URL shortening combined with pixel injection. Here's the simplified flow:

1. You create a short link using a URL shortener that supports retargeting pixels.
2. You attach one or more pixels (Meta, Google, LinkedIn, TikTok, X) to the link.
3. When someone clicks the short link, the shortener loads an intermediate page (or a 302 redirect with pixel-firing logic) that drops the cookie/pixel.
4. The user is then redirected to the final destination — they barely notice the delay.
5. The clicker is now in your custom audience on each ad platform, ready to be retargeted.

What You Need Before You Start

Before you set up your first retargeting link, gather the following:

• An ad account on at least one platform (Meta Business Manager, Google Ads, LinkedIn Campaign Manager, TikTok Ads, or X Ads).
• Your pixel IDs from each platform you plan to retarget on.
• A URL shortener that supports retargeting pixels — such as Lunyb, Rebrandly, Bitly, or Replug.
• A custom branded domain (optional but strongly recommended for trust and CTR).
• A clear campaign objective — what will you advertise to people who click your links?

How to Set Up Link Retargeting in 7 Steps

Follow this exact sequence to set up link retargeting properly the first time. The whole process takes about 30–45 minutes.

Step 1: Create Pixels on Each Ad Platform

If you don't already have pixels installed, create them now. Each ad platform calls them something slightly different:

• Meta: Meta Pixel (found under Events Manager).
• Google Ads: Google Ads Tag / Remarketing Tag.
• LinkedIn: Insight Tag.
• TikTok: TikTok Pixel.
• X (Twitter): Universal Website Tag.

Copy the Pixel ID (not the full script) for each. You'll only need the ID — typically a 15–16 digit number — to paste into your link shortener.

Step 2: Choose a Link Shortener That Supports Retargeting

Not all shorteners support pixel-based retargeting. Choose one that does. For a deeper comparison of features and pricing, see our 2026 Buyer's Guide to URL Shorteners.

Platform	Retargeting Support	Pixels Per Link	Starting Price
Lunyb	Yes	Multiple	Free tier available
Rebrandly	Yes (paid plans)	Multiple	$13/mo
Bitly	Limited	1–2	$8/mo
Replug	Yes	Multiple	$19/mo

If you're undecided, our honest review of Lunyb and our Rebrandly review walk through real-world use cases.

Step 3: Connect Your Pixels to Your Shortener

In your shortener's dashboard, navigate to the Pixels, Integrations, or Retargeting section. Add a new pixel by selecting the platform and pasting the pixel ID you copied earlier. Give it a clear name like "Meta — Main" or "LinkedIn — B2B 2026" so you can identify it later.

Repeat for every ad platform you plan to use. Most marketers start with just Meta + Google, then expand once they see results.

Step 4: Add a Custom Branded Domain (Optional but Recommended)

Generic shortener domains can look spammy and reduce click-through rates by 20–35%. A branded domain like go.yourbrand.com or yb.co dramatically increases trust. Most shorteners let you connect a custom domain via a CNAME DNS record.

Step 5: Create Your First Retargeting Link

Now build your first link:

1. Click "Create new link" in your shortener dashboard.
2. Paste the destination URL (e.g., a relevant industry article, your partner's blog post, a YouTube video, or a news story).
3. Customize the slug (e.g., /ai-trends-2026).
4. Attach the pixels you want to fire on this link.
5. Add UTM parameters for analytics tracking.
6. Save and copy your new link.

Test it by clicking the link yourself, then check your ad platform's events manager — you should see your pixel fire within a few minutes.

Step 6: Share Your Link Strategically

Distribute your retargeting link wherever your target audience hangs out:

• Social media posts — share useful third-party content on LinkedIn, X, Facebook, and Threads.
• Email newsletters — link out to industry news using your pixel-enabled shortener.
• Community forums — Reddit, Slack, Discord (only where allowed).
• Bio links — use a branded short link in your social bios.
• Guest contributions — link to your favorite resources from guest posts.

The goal: maximize legitimate, value-driven clicks that build your audience pool.

Step 7: Build Custom Audiences and Launch Ads

After 100–500 clicks have accumulated, head into your ad platform and create a Custom Audience from Pixel. Choose the time window (e.g., "All visitors in the past 30 days"). Once the audience reaches your platform's minimum size (1,000 on Meta, 100 on LinkedIn), you can run ads.

Start with a simple campaign:

• Audience: people who clicked your shared links.
• Creative: a relevant ad tied to the content theme they engaged with.
• Offer: lead magnet, free trial, webinar, or product demo.
• Budget: $5–$20/day to test.

Link Retargeting Best Practices

Match the Ad to the Content Theme

If your shared link was about "AI in healthcare," don't retarget those clickers with a generic offer. Speak to the same theme. Relevance dramatically improves conversion rates.

Segment by Topic

Create separate pixels (or use UTM-based audiences) for different content themes. Someone who clicked an article on "crypto regulation" is a different buyer persona than someone who clicked "NFT art trends." Treat them differently.

Don't Cloak or Mislead

Always link to content that genuinely matches the headline or context. Cloaking links violates ad platform policies and erodes trust quickly. Pixel-enabled links should feel completely transparent to the user.

Comply With Privacy Laws

GDPR, CCPA, and similar regulations apply. Make sure your destination pages and pixel use comply with consent requirements. Many shorteners offer built-in consent banners or geo-rules to restrict pixel firing in certain regions.

Use Frequency Caps

People hate seeing the same ad 40 times. Set frequency caps of 3–5 impressions per week to avoid ad fatigue and wasted spend.

Common Mistakes to Avoid

• Adding too many pixels per link. Each pixel adds a fractional delay. Stick to 2–3 platforms max per link.
• Forgetting to test. Always click your own link from an incognito window and verify the pixel fires.
• Ignoring branded domains. Generic shorteners get blocked on LinkedIn, Facebook, and inside corporate firewalls.
• Building one giant audience. Segment by content theme to keep relevance high.
• Running ads too early. Wait until your audience is at least 1,000 users on Meta before launching.

How Much Does Link Retargeting Cost?

The cost has two parts: the shortener subscription and the ad spend.

Component	Typical Monthly Cost
URL shortener with retargeting	$0–$50
Branded domain registration	$1–$2 (annualized)
Test ad budget	$150–$600
Scaled ad budget	$1,000+

Most small businesses start with under $200/month total and scale based on cost-per-acquisition. For shortener pricing details, our Rebrandly pricing review goes into depth on what each tier offers.

Measuring Success

Track these KPIs to know if link retargeting is working:

• Click-through rate (CTR) on your shared links.
• Audience growth rate — how many users you add per week.
• Retargeting ad CTR — should be 2–5x higher than cold traffic.
• Cost per acquisition (CPA) compared to cold campaigns.
• Return on ad spend (ROAS) — the ultimate scoreboard.

Frequently Asked Questions

Is link retargeting legal?

Yes, link retargeting is legal in most jurisdictions, but it must comply with regional privacy laws such as GDPR (EU/UK), CCPA (California), and LGPD (Brazil). You should ensure your destination pages have proper consent mechanisms, and many shorteners now offer built-in geo-restrictions to block pixel firing in regions that require explicit consent.

How many clicks do I need before I can start running retargeting ads?

Meta requires a minimum audience of 1,000 users, LinkedIn requires 300, and Google Ads requires 100 for display and 1,000 for search remarketing. Most marketers wait until they have a healthy buffer above the minimum (e.g., 2,000+ on Meta) before launching, since audiences shrink as the lookback window expires.

Can I add multiple pixels to one shortened link?

Yes — most modern shorteners like Lunyb support stacking multiple pixels on a single link. However, each additional pixel adds slight latency to the redirect, so we recommend limiting it to 2–3 pixels per link to keep the user experience fast.

Does link retargeting work for content I share on LinkedIn or X?

Absolutely — that's one of its primary use cases. You can share any third-party article using your pixel-enabled short link, and every engaged clicker becomes part of your custom audience. Just make sure your branded domain is whitelisted (LinkedIn occasionally blocks raw shortener domains).

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

Traditional retargeting only captures visitors who land on websites you own (where your pixel is installed). Link retargeting lets you build audiences from clicks on any destination — including news sites, partner blogs, and YouTube videos — by routing the click through a pixel-enabled short link first.

Final Thoughts

Link retargeting is one of the highest-leverage marketing tactics available in 2026. With minimal setup time and modest budgets, you can turn every link you share — even links to other people's content — into a long-term audience-building asset. Pick a reliable shortener, set up your pixels properly, segment your audiences by topic, and stay aligned with privacy regulations. Within 60–90 days, you'll have a warm audience pool that converts at 2–5x the rate of cold traffic.

Start small, test continuously, and scale what works.
