Facebook Ads Retargeting: Step-by-Step Setup Guide

Q: Does retargeting work without the Meta Pixel?

You can retarget using on-platform data such as video viewers, page engagers, and lead form openers without the pixel. However, website-based retargeting requires the pixel. The pixel is always worth installing regardless of whether you plan to run ads immediately.

Q: How long should my retargeting window be?

It depends on your sales cycle. For impulse purchases use 7–14 days. For considered purchases such as services, software, or high-ticket items use 30–60 days. For long B2B sales cycles use up to 180 days.

Q: Is retargeting affected by iOS privacy changes?

Yes. Apple's App Tracking Transparency framework reduced the accuracy of pixel-based retargeting for iOS users. Meta recommends using Conversions API alongside the pixel for more reliable tracking, as CAPI sends conversion data directly from your server to Meta, bypassing browser-based restrictions.

Q: Will people know they are being retargeted?

Facebook shows a Sponsored label on all ads. Some users notice the correlation between browsing a site and seeing related ads, but most do not. What they will notice is whether your ad is relevant and useful, which is why personalised retargeting copy outperforms generic ads.

By Conversite · 6 minute read

Most people who visit your website don't convert on the first visit. Research consistently shows that 97–98% of first-time website visitors leave without taking action.

Facebook retargeting lets you stay in front of those visitors after they leave. Instead of starting from scratch with cold audiences, you're re-engaging people who already know your brand — which is why retargeting campaigns typically have conversion rates 2–3× higher than prospecting campaigns.

This guide walks through the complete setup: installing the Meta Pixel, building your retargeting audiences, creating your campaign, and writing ads that actually convert warm traffic.

What Is Facebook Retargeting?

Facebook retargeting (also called remarketing) is a strategy that shows ads specifically to people who have previously interacted with your business — by visiting your website, watching your videos, engaging with your Facebook or Instagram page, or submitting their contact information.

When someone visits your website, a small piece of code called the Meta Pixel fires and records that visit. Facebook then matches that visitor to a Facebook or Instagram user and allows you to target them with ads.

The result: your ads reach people who are already familiar with your brand, rather than complete strangers.

Step 1: Install the Meta Pixel

The Meta Pixel is the foundation of all website-based retargeting. Without it, Facebook has no way of knowing who visited your site.

Create Your Pixel

Go to Meta Events Manager
Click + Connect data sources → Web
Name your pixel (use your business name — you only need one pixel per ad account)
Click Continue

Install the Pixel on Your Website

You have three options:

Option A: Manual installation (paste into your website)

In Events Manager, select Install code manually
Copy the base pixel code
Paste it into the <head> section of every page on your website — before the closing </head> tag
If you're on HubSpot, go to Settings → Tracking & Analytics → Tracking Code and paste it in the additional scripts field

Option B: Partner integration (easiest) Meta has direct integrations with most major platforms. If you're on Shopify, WordPress, Squarespace, or Wix:

In Events Manager, select Use a partner integration
Choose your platform
Follow the guided steps — no manual code needed

Option C: Google Tag Manager If you're using GTM:

In GTM, create a new tag → Tag type: Custom HTML
Paste the Meta Pixel base code
Set trigger to All Pages
Publish the container

Verify Your Pixel Is Firing

Install the Meta Pixel Helper Chrome extension. Visit your website — the extension icon should show your pixel ID with a green indicator, confirming it's firing correctly.

Step 2: Set Up Standard Events

The base pixel tracks page views by default. To build more specific retargeting audiences (people who added to cart but didn't purchase, people who reached a specific page), you need to add standard events.

Key standard events to implement:

Event	When to fire	Use case
ViewContent	Product/service page	Retarget page viewers
Lead	Thank-you page after form submit	Exclude converted leads
InitiateCheckout	Checkout start page	Cart abandonment retargeting
Purchase	Order confirmation page	Exclude purchasers
Contact	Contact page visit	Warm audience targeting

How to add an event (manual method): Below your base pixel code, add the event code. For a thank-you page:

fbq('track', 'Lead');

For a product page:

fbq('track', 'ViewContent', {

content_name: 'Product Name',

content_category: 'Category',

value: 0.00,

currency: 'USD'

});

Place event codes on the specific pages they correspond to — not on every page.

Step 3: Build Your Retargeting Audiences

Now that your pixel is collecting data, you can build Custom Audiences from your website visitors.

How to Create a Website Custom Audience

Go to Meta Ads Manager → Audiences
Click Create audience → Custom audience
Select Website as the source
Choose your pixel
Define the audience rules

Audience Segments to Create

All website visitors (30 days)

Rule: All website visitors
Time window: Last 30 days
Use for: General retargeting to anyone who visited your site

All website visitors (90 days)

Same as above but 90-day window
Use for: Broader awareness retargeting, lower frequency

Specific page visitors

Rule: People who visited a specific page (e.g. your pricing page, services page)
Use for: High-intent retargeting — these people showed strong purchase intent

Visitors who didn't convert

Rule: Visited website → Did NOT trigger Lead or Purchase event
Use for: Re-engage people who browsed but didn't take action

Video viewers (25% / 50% / 75%)

Source: Video → select specific videos from your Facebook/Instagram
Use for: Retarget people who watched your video content — warm but not yet on-site

Page engagers

Source: Facebook/Instagram account → People who engaged with your page or posts
Time window: Last 60–90 days
Use for: Re-engage social followers who haven't visited your site yet

Lead form openers

Source: Lead form → People who opened but didn't submit
Use for: Re-engage people who showed intent but didn't complete the form

Step 4: Create Your Retargeting Campaign

Campaign Structure

Campaign (Retargeting)

├── Ad Set 1: Hot — Website visitors (last 14 days)

├── Ad Set 2: Warm — Website visitors (15–30 days)

└── Ad Set 3: Engaged — Page engagers + video viewers

Splitting by recency lets you show more aggressive offers to recent visitors (who are closest to converting) and softer reminder ads to older visitors.

Campaign Settings

In Ads Manager, click + Create
Select your objective — for most retargeting campaigns:

Leads if you're collecting form submissions
Sales if you're tracking purchases
Engagement if you're retargeting to build familiarity before a conversion push

Name your campaign clearly: "Retargeting — [Month Year]"

Ad Set Settings

1. Budget: Start with $10–20/day per ad set. Retargeting audiences are small — overspending on a small audience leads to ad fatigue fast.

2. Audience: Select your Custom Audience from Step 3. If your audience is very small (under 1,000 people), consider expanding the time window or combining audiences.

3. Exclusions — critical: Always exclude people who have already converted:

Add your Lead or Purchase Custom Audience as an Exclusion
This prevents you from wasting budget showing "Sign up" ads to people who already signed up

4. Placement: For retargeting, start with Automatic placements. Facebook will allocate across Facebook Feed, Instagram Feed, Stories, Reels, and Audience Network based on performance.

Step 5: Write Retargeting Ad Copy

Retargeting ads work differently from cold-audience ads. Your audience already knows who you are — your copy should reflect that.

Principles for Retargeting Copy

Acknowledge they've already shown interest (subtly) Don't be creepy ("We saw you visited our website!") but do speak to someone who's already aware. "Still thinking it over?" is subtler than "Hi, we tracked you."

Remove friction from the next step What stopped them from converting? Common barriers: price uncertainty, time commitment, trust. Address these directly.
- "No contract. Cancel anytime." (removes commitment fear)
- "Free 30-minute call — no obligation." (removes time/sales pressure)
- "Join 2,000+ marketers already using this." (adds social proof)

Use a different offer or angle to each recency tier
- Recent visitors (1–7 days): Direct reminder. "You were just looking at [service/product] — here's what you need to know."
- Older visitors (8–30 days): Softer nudge with new information. "New guide: [topic relevant to what they viewed]."
- Engagers who haven't visited: Value-first. Share a useful piece of content to bring them to the site.

Test carousel ads with your most visited pages Carousel format lets you show multiple pages or products in one ad. For service businesses, use carousels to highlight different service categories or case studies.

Step 6: Set Up Frequency Caps

The biggest mistake in retargeting is showing the same ad to the same person 20 times. Ad fatigue kills retargeting performance fast.

Recommended frequency caps:

Hot audiences (1–14 days): Max 3 impressions per week
Warm audiences (15–45 days): Max 2 impressions per week
Older audiences (45–90 days): Max 1 impression per week

How to set frequency caps in Meta Ads Manager: In your ad set settings, under Optimisation & delivery, set Frequency cap to your desired limit. Note: frequency caps are only available with Reach objective campaigns. For conversion campaigns, monitor frequency in reporting and pause/rotate ads when frequency exceeds 3–4.

Step 7: Measure and Optimise

Key metrics for retargeting campaigns:

CTR: Should be higher than prospecting campaigns. Under 1% suggests ad fatigue or irrelevant creative.
Frequency: Monitor weekly. Above 4–5 frequency signals ad fatigue — rotate your creative.
Cost per result: Compare against your prospecting campaigns. Retargeting CPL/CPP should be lower.
ROAS (for e-commerce): Retargeting typically delivers 3–5× the ROAS of prospecting.

Weekly optimisation checklist:

Check frequency per ad set — rotate any creative above frequency 4
Compare performance across recency tiers — if recent visitors outperform, shift budget there
Add new exclusions as people convert
Refresh creative every 3–4 weeks to prevent fatigue

Frequently Asked Questions

How many website visitors do I need before retargeting works? You need at least 100 people in a Custom Audience before Meta will serve ads. In practice, 500+ visitors gives the algorithm enough data to optimise. If your website traffic is low, start by building audiences over a longer time window (60–90 days) and combine with video viewers and page engagers.

Does retargeting work without the Meta Pixel? You can retarget using on-platform data (video viewers, page engagers, lead form openers) without the pixel — but website-based retargeting requires the pixel. The pixel is always worth installing regardless of whether you plan to run ads immediately.

How long should my retargeting window be? Depends on your sales cycle. For impulse purchases: 7–14 days. For considered purchases (services, software, high-ticket items): 30–60 days. For long sales cycles (B2B, enterprise): up to 180 days.

Will people know they're being retargeted? Facebook shows a small "Sponsored" label on all ads. Some users notice the correlation between browsing a site and seeing related ads, but most do not. What they will notice is whether your ad is relevant and useful — which is why personalised retargeting copy outperforms generic ads.

Is retargeting affected by iOS privacy changes? Yes. Apple's App Tracking Transparency (ATT) framework, introduced in iOS 14.5, reduced the accuracy of pixel-based retargeting for iOS users. Meta recommends using Conversions API (CAPI) alongside the pixel for more reliable tracking. CAPI sends conversion data directly from your server to Meta, bypassing browser-based restrictions.
