Remarketing with Google Ads: Strategies for 400-800% ROAS

In practice: the vast majority of your website visitors don't buy on their first visit. Remarketing brings them back – and typically far cheaper than cold traffic. In this guide, you'll learn remarketing strategies for 400-800% ROAS.

What is Remarketing?

Remarketing (also retargeting) shows ads to people who have already visited your website.

Example:

1. User visits your online shop, adds product to cart
2. Leaves website without purchase
3. Sees your display ad the next day: "10% discount on your cart!"
4. Returns and buys

Why so effective?

• ✅ 90% cheaper: CPC €0.20-0.80 instead of €2-5
• ✅ 3-5x higher CR: Warm leads instead of cold traffic
• ✅ Higher AOV: Returning visitors often buy more
• ✅ Brand Recall: Multiple touchpoints = higher trust

Performance comparison:

• Cold Traffic: CPC €3, CR 2%, CPA €150
• Remarketing: CPC €0.50, CR 6%, CPA €8

18x cheaper per conversion!

The 4 Main Remarketing Types

1. Standard Display Remarketing

What: Banner ads on millions of websites (Google Display Network)

For whom: All visitors to your website

Setup:

Google Ads → Create Campaign → Display
→ Goal: Sales / Leads
→ Audience: Website visitors

Best Use: Brand awareness, broad reach

Cost: CPC €0.20-0.60

2. RLSA (Remarketing Lists for Search Ads)

What: Ads in Google search for previous website visitors

Example:

• User visits your shop, doesn't buy
• A week later they google "running shoes buy"
• Your ad appears (with higher bid, because you know: they know you!)

Setup:

Search campaign → Audiences → Observation
→ Add website visitors
→ Bid adjustment: +50-150%

Best Use: High-intent keywords with known visitors

Cost: Like search ads, but higher ROI

3. Dynamic Remarketing (E-Commerce)

What: Shows exactly the products the user viewed

Example:

[Display ad]
"You viewed these products:"
[Nike Air Zoom Pegasus 40 - €129]
[Adidas Ultraboost - €159]
"Now 15% off!"

Setup: Requires product feed (Google Merchant Center)

Best Use: E-Commerce with many products

Performance: Often 2-3x better CR than standard remarketing

4. Video Remarketing (YouTube)

What: Video ads on YouTube for website visitors

Best Use:

• Brand building
• Product demos
• Testimonials

Cost: CPV €0.05-0.20 (extremely cheap!)

Remarketing Setup: Step by Step

Step 1: Install Google Ads Tag

Method A: Google Tag Manager (recommended)

GTM → Create Tag → Google Ads Remarketing
→ Enter Conversion ID
→ Trigger: All Pages
→ Publish

Method B: Direct

Google Ads → Tools → Audience Manager
→ Audience Sources → Google Ads Tag
→ Code on all pages

Test: Go to website, then check in Google Ads: "Audience size" should be >0

Step 2: Create Audiences

Basic segments:

1. All Visitors

Audience Manager → + New Audience
→ Website visitors
→ Name: "All Visitors 30 Days"
→ Duration: 30 days

2. Cart Abandoners (E-Commerce)

→ URL contains: "/checkout" or "/cart"
→ URL does NOT contain: "/thank-you"
→ Duration: 30 days

3. Product Page Visitors without Purchase

→ URL contains: "/product/"
→ URL does NOT contain: "/thank-you"
→ Duration: 30 days

4. Past Customers (Exclusion or Upsell)

→ URL contains: "/thank-you"
→ Duration: 540 days (max)

Step 3: Time-Based Segmentation

Why important? Intent changes over time.

Setup:

Audience 1: "Hot Leads" (0-7 days)
Audience 2: "Warm Leads" (8-30 days)
Audience 3: "Cold Leads" (31-90 days)

Different messages per segment!

The Remarketing Sequence Strategy

Day 1-7: Urgency & Incentive

Audience: Fresh visitors (highest intent!)

Message: Discount offer

"Still thinking? 10% off with code: WELCOME10"
"Only valid for 48 hours!"

Bid: +100-150% (aggressive!)

Channels: Display + RLSA

Why: Highest conversion probability

Day 8-30: Social Proof & Trust

Audience: Visitors who didn't convert

Message: Build trust

"Over 10,000 satisfied customers"
"★★★★★ 4.9 out of 5 stars"
[Show customer testimonials]

Bid: Standard

Channels: Display + YouTube

Why: Overcome purchase barriers (trust)

Day 31-90: Educational Content

Audience: Cold leads

Message: Value instead of sales

"The 10 Best Running Tips for Beginners"
"Free Guide: Finding the Perfect Running Shoe"

Bid: Low (-30%)

Channels: Display + Video

Why: Re-engagement through content, not blatant advertising

Advanced Remarketing Tactics

1. Cross-Sell & Up-Sell (for existing customers)

Setup:

Audience: "Running Shoe Buyers"
→ URL contains: "/thank-you"
AND Product ID Parameter

Campaign: "Upsell Premium Socks"

"Thanks for your purchase! Complement your running shoes:
Premium Running Socks - Now 20% off for existing customers"

Performance: 500-800% ROAS (extremely cheap, high CR)

2. Abandoned Cart Recovery

The most profitable remarketing form!

Sequence:

1-2 hours later: Email + Display

"You forgot something in your cart!"

24 hours: Incentive

"Cart waiting! + Free shipping on orders today"

3 days: Urgency

"Last day! Products in cart almost sold out"

Conversion Rate: 15-30% (!) vs. 2-4% for cold traffic

3. Customer Match (Email Lists)

What: Upload your customer list → Remarketing in Google

Setup:

Audiences → + New Audience → Customer List
→ Upload CSV with emails

GDPR: Consent required!

Use Cases:

• Exclude existing customers from acquisition campaigns
• VIP customers with exclusive offers
• Upsell/Cross-sell

Match Rate: 40-70% (Google finds these emails)

4. Similar Audiences (Lookalikes)

What: Google finds people similar to your visitors

Setup:

Audience → + Similar Audience
→ Base: "Buyers last 90 days"

Size: 10-50x larger than original list

Performance: 30-50% worse than remarketing, but 2x better than cold traffic

Use Case: Scaling when remarketing pool too small

Budget & Bidding Strategies

Budget Allocation

Recommended split:

Cold Traffic (Acquisition): 60-70%
Remarketing: 30-40%

Why not 100% remarketing?

• Need new traffic for remarketing pool
• Remarketing audience exhausts itself

Remarketing Budget Distribution:

Cart Abandoners: 40% (highest ROI)
Product Page Visitors: 30%
All Visitors: 20%
Similar Audiences: 10% (Testing)

Bids by Segment

Hot Leads (0-7 days, Cart Abandoners):

• Bid: +100-150% vs. Cold Traffic
• Reason: 10x higher conversion probability

Warm Leads (8-30 days):

• Bid: +20-50%

Cold Leads (31-90 days):

• Bid: -20-40% (keep cheap)

RLSA (Search):

• Bid adjustment: +50-100% for visitors

Creative Strategies

Display Ad Best Practices

Format Mix:

• Responsive Display Ads (automatic)
• • Custom HTML5 Banners (for A/B tests)

Elements that work:

1. Product image (what they viewed)
2. Discount badge ("20% OFF")
3. Urgency ("Only 24h left!")
4. Social Proof ("10,000+ customers")
5. CTA button ("Get it now")

A/B Test Ideas:

• 10% vs. 15% vs. 20% discount
• "Buy now" vs. "Get it now"
• Product image vs. Lifestyle image

Dynamic Creative

What: Ads automatically adapt to users

Setup (for E-Commerce):

Campaign → Ads → Dynamic Ads
→ Connect feed (from Merchant Center)

Shows automatically:

• Products user viewed
• With current prices
• Possibly with sale prices

Performance Lift: +50-100% vs. static ads

Common Remarketing Mistakes

Mistake #1: Forgot Frequency Capping

Problem: User sees your ad 50x/day → annoying!

Solution:

Campaign → Settings → Advanced Settings
→ Frequency Capping: Max 3-5 impressions per day

Mistake #2: Too Long Membership Duration

Problem: 540 days remarketing → irrelevant after 3 months

Better:

• Cart Abandoners: 30 days
• Product Pages: 60 days
• All Visitors: 90 days

Mistake #3: No Segmentation

Problem: All visitors treated equally

Reality:

• Cart Abandoners: 15% CR
• Homepage Visitors: 2% CR

Solution: Separate campaigns with different bids

Mistake #4: Only Display

Wasted Potential: RLSA often more profitable!

Use all channels:

• Display Remarketing
• RLSA (Search)
• YouTube Remarketing
• Gmail Remarketing
• Discovery Ads Remarketing

Mistake #5: Not Excluding Existing Customers

Problem: You advertise to people who already bought

Solution:

Campaign → Audiences → Exclusions
→ Exclude "Buyers last 30 days"

Exception: Upsell campaigns!

Remarketing & GDPR

Important: Remarketing requires consent (Cookie Consent)

Compliance:

1. ✅ Cookie banner with opt-in (not just opt-out)
2. ✅ Privacy policy mentions remarketing
3. ✅ Google Consent Mode V2 (mandatory from March 2024)

Consent Mode Setup:

GTM → Configure Google Consent Mode
→ Ad Storage = Requires Consent

Impact: 30-60% smaller remarketing audience (cookie rejection)

But: Compliance > Growth

How does remarketing work with Google Ads?

Google Ads Tag tracks website visitors, saves them in audiences (GDPR compliant with consent). Later, these users see your ads on Google Display Network, YouTube, Gmail, or in Google Search (RLSA). Only those who visited your website see remarketing ads. Membership duration: 1-540 days.

Is remarketing GDPR compliant?

Yes, with consent! Required: Cookie banner with opt-in (not just info), privacy policy mentions remarketing, Google Consent Mode V2 implemented. Without consent: No remarketing tracking. Impact: 30-60% smaller remarketing pool due to cookie rejection, but legally safe.

What's the difference between remarketing and retargeting?

Terms are used synonymously, mean the same: ads for website visitors. "Remarketing" = Google's term, "Retargeting" = generic term. Technically no difference. Both: User is tagged, sees ads later. Google calls it "Remarketing", Facebook "Retargeting".

How big does my remarketing list need to be?

Display Remarketing: Min. 100 active users (last 30 days). RLSA: Min. 1,000 active users. Google Customer Match: Min. 1,000 emails. Optimal: 5,000-10,000+ for stable campaigns. Below minimum: Campaign won't run. Recommendation: 5,000+ traffic/month for remarketing start.

Which remarketing strategy works best?

Cart Abandoner Remarketing: Highest ROI (800-1500% ROAS), 15-30% CR. Sequences by time: Day 1-7 discount, Day 8-30 social proof, Day 31-90 content. Dynamic Remarketing (E-Commerce): Shows exactly viewed products, 600-1200% ROAS. RLSA: +50-100% bid adjustment for visitors in Search.

How often should remarketing ads appear?

Frequency Capping: Max 3-5 impressions per day, max 15-20 per week optimal. Too much: Annoys users, brand damage. Too little: Not effective. Cart Abandoners: Higher frequency ok (5-7/day first 3 days). Display: 3/day. RLSA: No cap (only in search).

Is remarketing worth it for small businesses?

Yes, especially! Benefits: 90% cheaper than cold traffic, works with small budget (from €200/month), highest ROI of all channels. Requirements: Min. 3,000-5,000 website visitors/month for sufficient list. Under 1,000 visitors/month: First traffic generation, then remarketing.
