Most marketers obsess over ROAS when measuring retargeting campaign performance. While return on ad spend matters, relying on ROAS alone is like driving while looking only at your speedometer—you're tracking one important metric but missing critical information that determines whether you're actually heading in the right direction.

Traditional metrics like clicks, impressions, and even ROAS don't tell the full retargeting story. Retargeting campaigns operate fundamentally differently than prospecting campaigns, requiring a unique set of success indicators. A campaign with strong ROAS might be underperforming if frequency is through the roof. Another campaign with modest ROAS could be your best performer when you account for incremental lift and assisted conversions.

This guide reveals the complete metrics framework for measuring retargeting success. You'll learn which KPIs actually matter, how to interpret them in retargeting context, and how to build a measurement system that drives better optimization decisions.

Core Retargeting Metrics That Matter

Beyond basic performance indicators, these metrics provide insight into retargeting effectiveness:

Incremental Conversion Rate

The difference in conversion rates between users exposed to retargeting ads and those who aren't. This is the single most important retargeting metric because it measures actual impact, not just correlation.

How to calculate: Set up a holdout group representing 5-10% of your retargeting audience who won't see ads. Compare conversion rates: Example: If exposed users convert at 8% and control converts at 5%: 
Incremental Lift = (8% - 5%) / 5% = 60% lift
This means retargeting is driving a 60% increase in conversions beyond baseline. Without measuring incremental lift, you can't distinguish between correlation (retargeted users convert) and causation (retargeting caused conversions). Example: If exposed users convert at 8% and control converts at 5%: 
Incremental Lift = (8% - 5%) / 5% = 60% lift
This means retargeting is driving a 60% increase in conversions beyond baseline. Without measuring incremental lift, you can't distinguish between correlation (retargeted users convert) and causation (retargeting caused conversions). Target Range: 30-80% incremental lift is strong performance. Above 100% suggests highly effective retargeting or that your holdout test needs refinement. Below 20% indicates retargeting is adding minimal value. View-Through Conversion Rate (VTCR) Conversions from users who saw your retargeting ad but didn't click, then later converted. This metric is crucial because retargeting often works through awareness and consideration, not direct response clicks. Calculation: Available in most ad platforms' reporting: 
VTCR = View-Through Conversions / Impressions
Example: 500 view-through conversions from 2,000,000 impressions = 0.025% VTCR
View-through conversions typically represent 30-50% of total retargeting conversions for awareness and consideration campaigns, but only 10-20% for conversion-focused campaigns. Target Range: View-through should represent 20-40% of total retargeting conversions. If it's below 10%, your creative may not be memorable enough. Above 60% suggests users are actively avoiding clicking your ads. Return Visit Rate Percentage of retargeting ad recipients who return to your site within the measurement window, regardless of conversion. Calculation: 
Return Visit Rate = Unique Return Visitors / Unique Users Reached
Example: 10,000 users saw your retargeting ads, 3,200 returned to your site: 
Return Visit Rate = 3,200 / 10,000 = 32%
This leading indicator shows whether your ads successfully drive consideration before conversion happens. Use our ROAS Calculator alongside return visit tracking to understand the full funnel. Target Range: 15-30% return visit rate is typical. Below 10% suggests weak creative or poor message match. Above 40% indicates strong interest but may signal conversion rate optimization opportunities on-site. Engaged View Rate Percentage of users who engage with your ad (hover, pause video, expand) without clicking. This metric indicates creative resonance and message relevance. Available on platforms supporting engagement metrics: 
Engaged View Rate = Engaged Views / Total Impressions
Target Range: 5-15% for static ads, 20-40% for video ads. Low engaged view rates suggest creative isn't capturing attention even when served to interested audiences. Cost Per Return Visit How much you spend to get each user back to your site, measuring retargeting efficiency before conversion. Calculation: 
Cost Per Return Visit = Total Ad Spend / Total Return Visitors
Example: $5,000 spend driving 3,200 return visits: 
Cost Per Return Visit = $5,000 / 3,200 = $1.56
This metric helps diagnose whether ROAS issues stem from traffic acquisition costs or on-site conversion problems. Target Range: Should be 40-60% of your target CPA. If return visit cost is reasonable but conversions are low, focus on landing page optimization rather than ad optimization. Conversion Assist Rate Percentage of conversions where retargeting played a role but wasn't the last click. This reveals retargeting's contribution to multi-touch conversion paths. Available in multi-touch attribution reports: 
Assist Rate = Assisted Conversions / (Last-Click Conversions + Assisted Conversions)
Example: 200 last-click conversions, 300 assisted conversions: 
Assist Rate = 300 / (200 + 300) = 60%
Target Range: 40-70% is typical for retargeting. If assist rate is very high (>80%), your retargeting may be excellent at warming users but poor at closing. If very low (<20%), you may be getting last-click credit for conversions driven by other channels. These core metrics provide a complete view of retargeting performance beyond simple ROAS measurements. Track them weekly to identify trends before they significantly impact campaign efficiency.

Frequency and Reach in Retargeting Context

Frequency management is critical for retargeting success. Unlike prospecting campaigns where you continuously reach new users, retargeting works with finite audiences where overexposure creates waste and irritation. Frequency Metric Average number of times each user sees your retargeting ad within a time period. Calculation: 
Frequency = Total Impressions / Total Reach
Example: 800,000 impressions served to 100,000 unique users: 
Frequency = 800,000 / 100,000 = 8 impressions per user
Optimal Frequency Ranges:
  • Awareness Retargeting: 3-5 impressions per week
  • Consideration Retargeting: 5-8 impressions per week
  • Conversion Retargeting: 7-12 impressions per week
  • Cart Abandonment: 8-15 impressions over 7 days
Red Flags:
  • Frequency above 15: Almost certainly experiencing diminishing returns and wasted spend
  • Frequency below 2: Likely not achieving sufficient exposure for retargeting to work effectively
  • Rapidly increasing frequency: Audience saturation, need to expand or refresh
Frequency Segmentation Analysis Don't just track average frequency—segment performance by frequency levels: Example Analysis:
  • Frequency 1-3: ROAS 3.2x, 15% of conversions
  • Frequency 4-7: ROAS 5.8x, 50% of conversions
  • Frequency 8-10: ROAS 4.1x, 25% of conversions
  • Frequency 11+: ROAS 2.3x, 10% of conversions
This reveals that 4-10 impressions drives optimal performance, while frequency above 11 delivers poor returns. Use this data to set frequency caps that maximize efficiency. Effective Reach Percentage of your retargeting audience that sees your ad at optimal frequency (not too low, not too high). Calculation: 
Effective Reach = Users at Optimal Frequency / Total Users Reached
Example with optimal frequency 4-10 impressions:
  • 30,000 users saw ads 1-3 times
  • 45,000 users saw ads 4-10 times
  • 25,000 users saw ads 11+ times
Effective Reach = 45,000 / 100,000 = 45%
Target Range: 60-75% effective reach. Below 50% indicates either insufficient budget (too many users at low frequency) or poor frequency management (too many at high frequency). Above 80% suggests good frequency distribution. Reach Depletion Rate How quickly you're exhausting your available retargeting audience. Calculation: 
Reach Depletion Rate = 7-Day Reach / Total Audience Size
Example: 80,000 users reached in 7 days from 200,000-person audience: 
Reach Depletion Rate = 80,000 / 200,000 = 40% per week
At this rate, you'll reach your entire audience in 2.5 weeks. High depletion rates (>50% weekly) indicate you'll quickly saturate audiences and need expansion strategies. Target Range: 20-35% weekly reach depletion for sustainable retargeting. Above 50% requires audience expansion. Below 15% suggests underinvestment or overly restrictive targeting. Unique Reach Rate Percentage of your total addressable retargeting audience you're actually reaching. Calculation: 
Unique Reach Rate = Unique Users Reached / Total Retargeting Audience Size
Example: Reached 75,000 unique users from 250,000-person retargeting pool: 
Unique Reach Rate = 75,000 / 250,000 = 30%
Target Range: 40-70% for most campaigns. Below 30% indicates either insufficient budget or technical delivery issues. Above 80% suggests you're approaching audience saturation. Frequency and reach metrics work together to show whether you're distributing impressions efficiently across your audience or concentrating them wastefully on the same users repeatedly. Monitor these weekly alongside CPM metrics to understand total retargeting efficiency.

View-Through Conversions Explained

View-through conversions (VTC) are often misunderstood and underutilized in retargeting measurement. Unlike click-through conversions where a user clicks your ad then converts, view-through conversions occur when users see your ad without clicking, then later convert. Why View-Through Matters for Retargeting Retargeting builds awareness and consideration, not just direct response. Many users need to see your ad multiple times before they're ready to take action. They might see your retargeting ad on mobile while commuting, then convert hours later on desktop after remembering your brand. View-through conversions capture this awareness-driven behavior that click-through metrics miss entirely. View-Through Attribution Window The time period after seeing an ad during which conversions count as view-through. Common settings:
  • 1-day view: Conservative, captures only conversions very likely influenced by the ad
  • 7-day view: Moderate, balances attribution accuracy with capturing legitimate influence
  • 28-day view: Aggressive, risks overcrediting ads for conversions driven by other factors
Recommended: Use 1-day view-through windows for retargeting to avoid overcounting. Retargeting audiences are warm and high-intent, so legitimate ad influence should drive faster conversions. View-Through Conversion Rate Benchmarks Typical VTC rates by campaign type: Awareness Retargeting:
  • View-through: 50-70% of total conversions
  • Click-through: 30-50% of total conversions
Consideration Retargeting:
  • View-through: 35-50% of total conversions
  • Click-through: 50-65% of total conversions
Conversion/Cart Abandonment:
  • View-through: 15-30% of total conversions
  • Click-through: 70-85% of total conversions
If your view-through rate significantly differs from these benchmarks, investigate: High VTC (>70% of conversions):
  • Possible ad avoidance—users interested but not clicking ads
  • Landing page concerns—users prefer direct site entry
  • Attribution window too long—capturing coincidental conversions
  • Strong brand recall—ads driving consideration without clicks
Low VTC (<15% of conversions):
  • Creative not memorable or distinctive
  • Poor frequency—not enough exposures for awareness impact
  • Attribution window too short—missing legitimate influence
  • Audience already highly familiar with brand
Calculating View-Through Value Assign appropriate value to view-through conversions in ROAS calculations: Conservative Approach: Count view-through at 50% weight 
Weighted Revenue = (Click-Through Revenue × 1.0) + (View-Through Revenue × 0.5)
Example:
  • Click-through revenue: $20,000
  • View-through revenue: $15,000
  • Weighted revenue: ($20,000 × 1.0) + ($15,000 × 0.5) = $27,500
Moderate Approach: Count view-through at 70% weight 
Weighted Revenue = (Click-Through Revenue × 1.0) + (View-Through Revenue × 0.7)
Example:
  • Weighted revenue: ($20,000 × 1.0) + ($15,000 × 0.7) = $30,500
Full Credit Approach: Count view-through at 100% weight (platform default) 
Total Revenue = Click-Through Revenue + View-Through Revenue
Example:
  • Total revenue: $20,000 + $15,000 = $35,000
Choose your weighting method based on your view-through attribution window and retargeting strategy. Shorter attribution windows (1-day) justify higher weighting. Longer windows (7-28 day) should use conservative weighting. View-Through Incrementality Testing The most accurate way to measure view-through value is incrementality testing:
  1. Create a holdout group of 10% of retargeting audience
  2. Show ads with impression tracking but prevent conversions from being counted
  3. Compare actual conversions between impression-only group and full campaign group
  4. Calculate incremental lift from impressions alone
This reveals true view-through impact separate from click-through effects. View-through conversions are particularly valuable for retargeting because they capture the awareness and consideration benefits that make retargeting effective. Don't ignore them, but attribute them carefully to avoid overcounting campaign value.

Attribution Windows for Retargeting

Timeline diagram showing different attribution windows including 1-day, 7-day, and 28-day with their impact on retargeting conversion results
Attribution windows determine which conversions get credited to your retargeting campaigns. These settings dramatically affect reported performance, often creating 30-50% variance in ROAS for identical campaigns. Click-Through Attribution Windows Time after clicking an ad during which conversions count: 1-Day Click:
  • Best for: Short sales cycles, impulse purchases, promotional offers
  • Pros: Attributes only very direct conversions, minimizes overcounting
  • Cons: Undercounts retargeting influence on consideration-driven purchases
  • Typical impact: Shows 20-35% lower ROAS than 7-day
7-Day Click:
  • Best for: Standard e-commerce, most B2C purchases, SaaS trials
  • Pros: Captures typical decision cycles, industry standard for comparison
  • Cons: May overcount for very short cycles, undercount for longer cycles
  • Typical impact: Balanced attribution, standard baseline
28-Day Click:
  • Best for: High-consideration purchases, B2B, expensive items, complex decisions
  • Pros: Captures extended decision periods, accounts for research cycles
  • Cons: May attribute conversions that would have happened anyway
  • Typical impact: Shows 40-70% higher ROAS than 7-day
View-Through Attribution Windows Time after seeing an ad during which conversions count (without clicking): 1-Day View:
  • Recommended for: Most retargeting campaigns
  • Rationale: Warm audiences should convert quickly if ad drives action
  • Impact: Conservative VTC counts, minimizes coincidental conversions
7-Day View:
  • Recommended for: Awareness-focused retargeting, complex products
  • Rationale: Allows for consideration period after ad exposure
  • Impact: Moderate VTC counts, balances capture and accuracy
Choosing Attribution Windows Match attribution windows to your typical customer journey: Same-Day Purchase Cycle (impulse purchases, low-ticket items):
  • Click: 1-day
  • View: 1-day
  • Example products: Fashion accessories, consumables, digital products
Short Purchase Cycle (1-7 days):
  • Click: 7-day
  • View: 1-day
  • Example products: Standard e-commerce, subscription trials, promotional offers
Medium Purchase Cycle (1-2 weeks):
  • Click: 7-day
  • View: 7-day
  • Example products: Higher-ticket e-commerce, software purchases, service signups
Long Purchase Cycle (2-4 weeks+):
  • Click: 28-day
  • View: 7-day
  • Example products: B2B solutions, expensive equipment, complex services
Platform Default Settings Know your platform defaults to avoid unconscious attribution choices:
  • Meta (Facebook/Instagram): 7-day click, 1-day view
  • Google Ads: 30-day click, 1-day view
  • TikTok: 7-day click, 1-day view
  • LinkedIn: 30-day click, 1-day view
  • Pinterest: 30-day click, 1-day view
These differing defaults make cross-platform ROAS comparison misleading without standardization. Attribution Window Strategy
  1. Standardize across platforms: Use same windows for all retargeting campaigns
  2. Document your settings: Note attribution windows when reporting ROAS
  3. Test window sensitivity: Compare performance at different windows to find optimal setting
  4. Adjust conservatively: Err toward shorter windows for retargeting warm audiences
  5. Segment reporting: Track both conservative (1-day click) and moderate (7-day click) ROAS
Multi-Window Reporting Example Report ROAS across multiple attribution windows to understand sensitivity: Campaign spend: $10,000
  • 1-day click ROAS: 3.2x ($32,000 revenue)
  • 7-day click ROAS: 4.8x ($48,000 revenue)
  • 28-day click ROAS: 6.1x ($61,000 revenue)
This shows significant attribution window sensitivity. The "true" ROAS likely falls in the 4-5x range, with 1-day undercounting delayed conversions and 28-day overcounting coincidental ones. Attribution Window Impact on Optimization Attribution settings affect not just reporting but active optimization:
  • Campaign Budget Optimization: Shorter windows favor high-intent audiences, longer windows favor awareness tactics
  • Bid Strategy: Longer windows support higher bids by crediting more conversions
  • Audience Selection: Shorter windows reward recency (recent visitors), longer windows reward reach
Choose attribution windows intentionally based on your business model and customer behavior, then standardize them across all campaigns for consistent measurement. Review our CPA Calculator using standardized attribution windows for accurate cost per acquisition tracking.

Calculating Incremental Lift

Incremental lift is the gold standard metric for measuring retargeting effectiveness. It answers the critical question: How many conversions happened because of retargeting that wouldn't have occurred otherwise? The Incrementality Problem Basic ROAS measurement suffers from a fundamental flaw: it credits retargeting with all conversions from retargeted users, even those who would have converted without seeing any ads. This is called the baseline or organic conversion rate. For retargeting, baseline conversions are particularly high because you're targeting users who already visited your site and showed interest. Some percentage will naturally return and convert without any additional advertising. Setting Up Incrementality Testing Create a holdout experiment to measure true incremental impact:

Step Create Holdout Group

Randomly select 5-10% of your retargeting audience to exclude from seeing ads. This control group experiences no retargeting while the treatment group sees your normal campaign.

Step Track Both Groups

Monitor conversions from both groups over the same time period (typically 30-60 days).

Step Calculate Incremental Lift

Example Data:
  • Control group (no ads): 10,000 users, 400 conversions = 4.0% conversion rate
  • Treatment group (with ads): 90,000 users, 4,500 conversions = 5.0% conversion rate
Calculate Incremental Lift: 
Incremental Lift % = ((Treatment Rate - Control Rate) / Control Rate) × 100
Incremental Lift % = ((5.0% - 4.0%) / 4.0%) × 100 = 25% lift
This means retargeting is driving a 25% increase in conversion rate beyond the baseline.

Step Calculate Incremental Conversions

Incremental Conversions = Treatment Conversions - (Treatment Users × Control Rate)
Incremental Conversions = 4,500 - (90,000 × 0.04) = 4,500 - 3,600 = 900
Out of 4,500 total conversions, only 900 were incremental—directly caused by retargeting.

Step Calculate Incremental ROAS

Incremental ROAS = (Incremental Conversions × Average Order Value) / Ad Spend
Assuming $100 AOV and $30,000 ad spend: 
Incremental ROAS = (900 × $100) / $30,000 = $90,000 / $30,000 = 3.0x
Meanwhile, basic ROAS would show: 
Basic ROAS = (4,500 × $100) / $30,000 = $450,000 / $30,000 = 15.0x

The apparent 15x ROAS dramatically overstates true impact because it credits retargeting with all conversions, including the 3,600 that would have happened anyway.

Incremental Lift by Audience Segment

Different retargeting audiences show different baseline rates and incremental lift:

Cart Abandoners:
  • Baseline conversion rate: 8-15% (high—many already intend to purchase)
  • Typical incremental lift: 20-40%
  • Interpretation: Retargeting provides gentle reminder but most were likely to convert
Product Viewers (No Cart):
  • Baseline conversion rate: 2-5%
  • Typical incremental lift: 50-100%
  • Interpretation: Retargeting significantly increases conversion likelihood
Homepage/Category Visitors:
  • Baseline conversion rate: 0.5-2%
  • Typical incremental lift: 100-200%
  • Interpretation: Retargeting has strong impact on lower-intent users

This reveals that retargeting often delivers highest incremental lift (percentage increase) on lower-intent audiences but highest incremental conversion volume on high-intent audiences.

Ongoing Incrementality Monitoring

You can't run holdout tests constantly, but you can estimate incremental lift:

Method 1: Periodic Testing

Run incrementality tests quarterly or biannually to establish baseline rates, then apply those rates to ongoing performance.

Method 2: Statistical Modeling

Use historical data to model expected baseline conversion rates based on user behavior characteristics, then compare actual conversions to modeled baseline.

Method 3: Platform Tools

Meta offers Conversion Lift Studies and Google provides experimental approaches through campaign experiments to measure incrementality.

Incremental Lift Benchmarks

Realistic incremental lift by retargeting strategy:

  • Dynamic Product Retargeting: 40-80% lift
  • Static Brand Retargeting: 30-60% lift
  • Sequential Messaging: 50-90% lift
  • Cart Abandonment: 20-50% lift
  • Cross-Sell Retargeting: 60-100% lift

Lower lift percentages aren't necessarily worse if the baseline rate is high—absolute incremental conversions matter more than lift percentage.

Using Incremental Lift for Optimization

Once you know your incremental lift, you can:

1. Calculate true incremental ROAS for accurate profitability analysis

2. Compare segments to identify which audiences benefit most from retargeting

3. Optimize frequency by testing how lift changes at different frequency levels

4. Set realistic targets based on incremental rather than apparent performance

5. Allocate budget toward highest-lift segments and campaigns

Incremental lift transforms retargeting from a correlation metric (retargeted users convert) to a causation metric (retargeting causes conversions). This is the difference between reporting activity and proving value.

Platform-Specific Retargeting Metrics

Different platforms provide unique metrics that offer additional insight into retargeting performance. Here's what to track on each major platform:

Meta (Facebook/Instagram) Specific Metrics Cost Per 1,000 People Reached:

Different from CPM (cost per 1,000 impressions), this shows cost to reach unique users. For retargeting with high frequency, you'll serve many impressions to each user, making cost per people reached 3-5x higher than CPM.

Target: $5-$15 for retargeting campaigns

Hook Rate (Video Ads):

Percentage of users who watch at least 3 seconds of your video. Indicates whether your opening creative captures attention.

Target: 40-60% for retargeting (should be higher than prospecting)

Hold Rate (Video Ads):

Percentage of users who watch at least 15 seconds or to completion. Shows message resonance.

Target: 15-30% for retargeting

Outbound Click Rate:

Percentage of impressions that result in clicks to your website. Different from CTR which may include other engagement.

Target: 1.5-3.5% for retargeting (significantly higher than prospecting's 0.5-1.2%)

Google Display Network Specific Metrics Active View Viewable Impressions:

Impressions where at least 50% of the ad was visible for 1+ seconds. Indicates actual exposure quality.

Target: 70-85% viewability rate

Relative CTR:

Your CTR compared to other advertisers targeting the same placements. Shows competitiveness of your creative.

Target: 1.0x or higher (matching or beating competitors)

Engagement Rate:

Interactions with rich media ads (expansions, video plays, etc.) divided by impressions.

Target: 3-8% for interactive display ads

TikTok Specific Metrics 6-Second Video Views:

Users who watched at least 6 seconds of your video ad. Key engagement threshold on TikTok.

Target: 30-50% of impressions for retargeting

Video Play Actions:

Users who actively engaged (pause, rewind, expand) with your video.

Target: 5-12% of video views

Average Watch Time:

Average duration users watched your video ad.

Target: 8-12 seconds for 15-second ads, 12-18 seconds for 30-second ads

LinkedIn Specific Metrics Social Actions:

Likes, comments, and shares on your sponsored content.

Target: 1-3% engagement rate for B2B retargeting

Lead Form Open Rate:

For lead gen campaigns, percentage of clicks that open your lead form.

Target: 40-60% (retargeting should show higher rates than cold traffic)

YouTube Specific Metrics View-Through Rate (VTR):

Percentage of impressions where user watched 30 seconds or to completion.

Target: 15-30% for retargeting (2-3x higher than prospecting)

Earned Actions:

Subscriptions, playlist additions, and watch time gained from users who engaged with your ad.

Target: Track trend over time; increasing earned actions show strong content resonance

Platform Comparison Framework

Track these standardized metrics across all platforms for comparison:

1. Effective CPM: Cost to reach 1,000 unique users at optimal frequency

2. Qualified Click Rate: Clicks that result in site visits over 10 seconds

3. Return Visit Rate: Site visits from ad recipients / users reached

4. Cost Per Return Visit: Total spend / total return visits

5. View-Adjusted ROAS: ROAS accounting for view-through conversions

6. Incremental ROAS: ROAS after removing baseline conversions

These normalized metrics allow you to compare retargeting efficiency across platforms despite different interfaces and native metrics.

  5. Set segment-specific ROAS targets based on incremental data
Quarter 1:
  1. Complete initial incrementality testing cycle
  2. Implement multi-touch attribution tracking
  3. Develop creative refresh schedule based on frequency/performance data
  4. Build automated alerts for key metric thresholds
  5. Create stakeholder reporting templates
The Measurement Mindset Shift

Traditional advertising measurement asks: "How much revenue did this campaign generate?"

Advanced retargeting measurement asks: "How much incremental revenue did this campaign generate that wouldn't have occurred otherwise, accounting for baseline conversions, multi-touch attribution, and both click and view-through mechanisms?"

This shift from correlation to causation, from apparent to incremental performance, transforms retargeting from a supplementary tactic into a precisely measured, systematically optimized revenue driver.

By implementing the metrics framework outlined in this guide, you'll move beyond surface-level ROAS numbers to understand the true contribution of your retargeting campaigns. You'll identify which audience segments deliver real incremental value, which frequency levels maximize efficiency, and how retargeting fits into your broader multi-channel attribution model.

Start with the essential metrics this week, build your measurement infrastructure this month, and refine your approach this quarter. The result will be retargeting campaigns you can measure accurately, optimize confidently, and scale profitably.

Measurement isn't just about reporting what happened—it's about understanding why it happened and what to do next. Build your complete retargeting measurement system, and you'll transform uncertainty into strategic advantage.
