Using retargeting pixels

A retargeting pixel is a tiny piece of code that an advertising platform (Meta, TikTok, Google, Pinterest, Snap) gives you. You install it on your link page. When a visitor arrives, the pixel quietly tells the ad platform 'this person was here.' Later, when that visitor scrolls Instagram or watches a TikTok, the platform can show them your ad — because it recognises them as someone who already engaged with you.

You're not collecting personal data yourself. You're not stalking anyone. You're paying the ad platform for another shot at someone who already showed interest in you.

Why this matters for creators specifically

Link-in-bio visitors convert at much higher rates than cold audiences — typically 3–5× better. Retargeting them is the single highest-ROI form of paid acquisition available to creators. A $5–10/day budget retargeting your warm audience often outperforms a $50/day cold-targeting budget.

Before adding a pixel to LinkStacked, you need the pixel ID from your advertising platform. Here's where to find it for each major platform.

Meta (Facebook + Instagram) Pixel

Go to Meta Business Manager → Events Manager → Data Sources → Pixels. Create a new pixel if you don't have one (the wizard takes about 2 minutes), or copy the ID from an existing pixel. The ID is a 15–16 digit number.

Google Ads Tag

In Google Ads, go to Tools & Settings → Shared Library → Audience Manager → Your data sources. Find your Google tag ID — the format is "AW-XXXXXXXXX" (10 digits after the dash).

TikTok Pixel

In TikTok Ads Manager, go to Assets → Events → Web Events → Create Pixel. After creation, copy the pixel ID from the setup screen. The ID format is a string of letters and numbers, typically 20+ characters.

Pinterest Tag

Pinterest Ads → Conversions → Tag Manager. Create a tag if you don't have one and copy the Tag ID (a 13-digit number).

Snap Pixel

Snap Ads Manager → Events Manager → Pixel. Create a pixel and copy the ID — Snap pixel IDs are GUIDs (long, hyphenated strings of letters and numbers).

In your LinkStacked dashboard, go to Settings → Integrations → Retargeting pixels. Click "Add pixel".

1. 1Select your platform from the dropdown (Meta, Google Ads, TikTok, Pinterest, Snap)
2. 2Paste your pixel ID into the field
3. 3Optionally name it for reference (e.g. "Meta — Spring Campaign", "Google — Brand")
4. 4Toggle "Active" to enable the pixel immediately
5. 5Click Save

You can add multiple pixels — for example, one Meta + one Google + one TikTok — and they'll all fire simultaneously on every public profile page view. Performance impact is negligible (a few KB of script per pixel).

After adding your pixel, verify it's working. The five minutes you spend on verification saves you three months of wondering whether your pixel is broken when audience size doesn't grow.

Verification tools by platform

• Meta: Install the "Meta Pixel Helper" Chrome extension. Visit your profile. The extension shows a green check when the pixel fires correctly.
• Google: Install "Google Tag Assistant" Chrome extension. Enable recording, visit your profile, and check the tag list for "AW-XXXXXX" with a green status.
• TikTok: "TikTok Pixel Helper" Chrome extension does the same.
• Pinterest: Pinterest Tag Helper Chrome extension.
• All platforms: Check Events Manager (or equivalent) in your ad dashboard. PageView events should appear in real-time test mode within 30 seconds.

Cross-checking in the platform dashboard

Each platform has a real-time event tester. Meta's is in Events Manager → Test Events. Google's is in Tag Assistant. TikTok's is in Pixel Setup. Visit your profile, then check the tester for a PageView event in the last 60 seconds.

Pixels are legal and standard practice. But your visitors should know they're being tracked, and increasingly so should regulators. The ethical line and the legal line are converging.

What LinkStacked handles automatically

• Cookie/tracking banner: appears automatically when retargeting pixels are active.
• Visitor opt-outs: respected automatically — pixels don't fire for visitors who decline tracking.
• Region detection: stricter consent flows for EU visitors (GDPR), US visitors in California (CCPA), and other regulated regions.
• Consent log: stored anonymously and retrievable on request for compliance audits.

Best practices for ethical retargeting

• Be honest in your ads. Retargeting works best when ad creative is continuous with the original content — not when you bait-and-switch.
• Limit frequency. Show the same ad to the same person more than 3–5 times in a week and conversion drops sharply (and they start to resent you).
• Use exclusion audiences. Once someone converts, exclude them from further retargeting on that product. Showing them the same offer they just bought is a waste of ad budget and a bad experience.
• Respect retention windows. EU GDPR allows 13-month max retention for tracking cookies. Most platforms default to shorter than that anyway.

Once you have at least 1,000 unique pixel-tracked visitors, you can run a meaningfully effective retargeting campaign. Below that threshold the audience is too small for the ad platforms to optimise reliably.

Setup checklist

1. 1Create a custom audience in your ad platform: 'All website visitors in the last 30 days' is a solid starting point
2. 2Set up a campaign at $5–10/day budget targeting that audience
3. 3Use creative that's continuous with what they saw before — same face, same brand colours, same energy
4. 4Run for 7–10 days and watch cost-per-click and cost-per-conversion
5. 5Iterate the creative — most retargeting underperforms because the ad creative is too generic

Lookalike audiences (the next-level move)

Once you have 5,000+ unique visitors in your pixel data, you can ask the ad platform to build a 'lookalike audience' — people who behave similarly to your visitors. Lookalikes from pixel data are dramatically better than lookalikes from email lists, because the underlying signal (visited link page) is closer to actual purchase intent than a passive follow.
