For a long time, a UGC campaign was measured by its impressions and likes. A video with 500,000 views was considered a success. A creator with 100,000 followers was a good default choice.
These reflexes are outdated. And brands that continue to drive their UGC campaigns based on vanity metrics are missing what truly matters.
Why? Because UGC is no longer just a brand awareness lever — it has become a commercial performance engine. In The Feed Ep.06, Frans, Creative Strategist at Socialsky, is direct: "On social media, there are no silos. What performs organically feeds the ads. The learnings from creators inform the brand strategy. Everything is connected."
A piece of UGC content can have 800 views and generate 40 sales. Another can have 2 million views and zero conversions. The distinction does not lie in the views — it lies in the business data.
The concrete limitations of vanity metrics:
Measuring a UGC campaign means reading three layers of performance: creative quality, the ability to convert, and overall business return. Each layer has its own indicators.
These are the KPIs that evaluate the content itself — before the algorithm even gives it reach. They make it possible to very quickly identify which creatives deserve to be amplified and which should be dropped.
Hook rate (or thumbstop ratio)
Definition: percentage of people who continue watching the video after the first 3 seconds. Benchmark: >30% is considered a good hook in UGC ads.
Tool: Meta Ads Manager ("Videos played at 3 seconds" column ÷ impressions) / TikTok Ads Manager.
Why it matters: if fewer than 30% of people get past the first 3 seconds, the hook is not working. Regardless of the quality of the rest, the message is not getting through.
Watch time (completion rate)
Definition: percentage of viewers who watch the video to 25%, 50%, 75% or 100%.
Benchmark: >50% at mid-video = strong content. <25% = problematic drop-off.
Tool: Meta Ads Manager, TikTok Ads Manager, YouTube Analytics.
Ep.06 insight: over-scripted, over-controlled content generates an early drop-off. The audience senses the ad and skips. The creator's authenticity maintains attention.
Frequency cap
Definition: average number of times the same person sees the same creative.
Benchmark: above 3-4, the creative becomes fatigued. Rotation is necessary.
Tool: Meta Ads Manager.
These are the KPIs that link content to action. They answer the question: did the message trigger a behaviour?
CTR (click-through rate)
Definition: percentage of people who click the link after seeing the content.
UGC benchmark: 1% to 1.5% is considered performant for Reels and TikTok Ads. Below 0.5%, the call-to-action or targeting needs to be reviewed.
Tool: Meta Ads Manager, TikTok Ads Manager.
Conversion rate
Definition: percentage of visitors who complete the desired action (purchase, sign-up, etc.) after clicking.
Benchmark: varies significantly by sector and product price. To be compared with the baseline of other acquisition channels to establish UGC outperformance.
Tool: GA4 + Meta Ads Manager reconciled via UTM.
CPA (cost per acquisition)
Definition: budget spent to generate a conversion.
Benchmark: UGC campaigns show a CPA on average 30 to 50% lower than classic brand creatives. The absolute reference is your target CPA calculated from your margin.
Tool: Meta Ads Manager.
Add-to-cart and payment initiations
Definition: micro-conversions that indicate purchase intent, even without a final purchase.
Value: they allow you to assess the quality of generated traffic even when the final purchase rate is low (friction on the cart page, high price, long purchase timeline).
Tool: Meta Pixel, GA4.
These are the KPIs that speak to the CFO as much as the media buyer. They evaluate the campaign in its entirety, including production costs.
ROAS (Return on Ad Spend)
Definition: revenue generated ÷ advertising budget spent.
Benchmark: a ROAS >2.0 is generally the scalability threshold in e-commerce. The exact target depends on your gross margin.
Important note: the ROAS reported in Meta Ads Manager post-iOS 14 is often underestimated by 20 to 40% due to tracking constraints. Incremental ROAS (measured via test vs. holdout group) is more reliable.
Tool: Meta Ads Manager, Triple Whale, Northbeam.
Global ROI
Definition: (revenue generated − total costs) ÷ total costs × 100. The difference from ROAS: ROI integrates ALL costs — production, gifting, usage rights, media budget, agency fees.
This is the overall profitability metric of the campaign.
LTV (lifetime value)
Definition: average revenue generated by a customer over the entire duration of their relationship with the brand.
Why it matters in UGC: a customer acquired through authentic UGC often has a higher LTV than one acquired through classic advertising, because they entered the brand through trust rather than promotion. Crossing ROAS and LTV makes it possible to accept a higher CPA if retention is strong.
Tool: your CRM + GA4 + Klaviyo.
This is the most complex — and the most important — question of a multi-creator UGC campaign. Without a rigorous attribution system, you do not know what works, and you cannot scale what performs.
Since the iOS 14 changes in 2021, browser-side tracking alone (via cookie) has been significantly degraded. The answer: coupling the Meta Pixel (browser-side) with the Conversions API — CAPI (server-side).
What this enables:
Recommended configuration: Pixel + CAPI via direct integration (Shopify, WooCommerce) or via a third-party tool (Elevar, Stape). Target event quality score: >6 in Meta Events Manager.
To attribute a conversion to a specific creator, every link used in UGC content must be tagged with unique UTM parameters per creator.
Recommended UTM structure for UGC:
This system makes it possible to:
The attribution window defines the period during which a conversion is attributed to a click or view of your UGC content.
The 7-day click + 1-day view window is the Meta standard for UGC e-commerce. For products with a long purchase cycle (premium cosmetics, tech, B2B), an extended window may better reflect the reality of the customer journey.
One of the most underused angles in UGC reporting. A UGC video viewed at the top of the funnel does not always generate a direct conversion — but it initiates the purchase journey that concludes 7 days later via a Google search or an email.
Assisted conversions measure this indirect contribution. In GA4, the "conversion paths" report shows how many times a UGC channel appears in the journey before the final conversion, even if it is not the last touchpoint.
Ep.06 insight: Frans describes this phenomenon as the true hidden value of UGC: "A creator finds a sales argument that the brand had not thought of. It goes into the editorial calendar for the following month, and it feeds the paid strategy. Everything is connected."
Recommended tools for multi-touch attribution: Triple Whale, Northbeam, AppsFlyer.
Having data is not enough — you still need to draw clear decisions from it. The Kill / Sustain / Scale framework is the most effective method for continuously managing a portfolio of UGC creators.
Criteria: ROAS above target threshold + CPA below the defined target + hook rate >30% + watch time >50% at mid-video.
Action: increase the media budget on this creative. Order variations (new hooks, cropped formats). Ask the creator for a long and a short version. Integrate the product argument that stands out into the organic content strategy.
Criteria: KPIs around average, without marked over- or underperformance. Or: strong organic content that has not yet been tested in paid.
Action: test new hooks on the same video body. Use via whitelisting (distribution from the creator's account rather than the brand account). Observe assisted conversions before making a decision.
Criteria: ROAS below profitability threshold + CPA above target + hook rate <20% + rising CPA after 7 days.
Action: cut the budget. Analyse why: bad hook? Bad targeting? Landing page issue? Document to avoid making the same mistake in the next casting.
Ep.06 insight: "It's not a drama if it doesn't work. We move on. We test, we see what works, we push." — Frans, The Feed Ep.06. That is exactly the Kill / Sustain / Scale logic applied on a daily basis.
A good UGC report must be readable in 5 minutes and decision-ready in 10. Here are the columns you absolutely must have in your dashboard.
Recommended tool for centralising: Google Looker Studio connected to Meta Ads + GA4 + a manual Google Sheet for creator metadata. For more advanced teams, Triple Whale or Northbeam provide a unified view and automatic multi-touch attribution.
The 7-day rule: do not judge a UGC creative before a minimum of 7 days of distribution. The algorithm needs a learning phase (minimum 50 conversions) before delivering reliable data. A Kill / Scale decision made too early can kill a creative that was about to take off.
Measuring the ROI of a UGC campaign is a profession in its own right. Between setting up tracking (Pixel + CAPI + UTM), building the dashboard, reading the data and making optimisation decisions — every step requires time and expertise.
At Socialsky, reporting is not a delivery of numbers at the end of a campaign. It is a continuous loop: creative test → analysis → Kill / Sustain / Scale decision → new brief → new test. This cycle is built on our Creative Lab and our Talent Pool of 500+ creators activated through a rigorous process.
Our promise: no silos between organic and paid. What performs with a nano-creator via gifting becomes the creative tested in paid the following week. And what converts in paid feeds the organic editorial calendar for the month after.

Business KPIs (ROAS, CPA, conversion rate) must take priority over vanity metrics. The hook rate and thumbstop ratio (>30%) allow you to assess creative quality upfront, before even analysing conversion.
The combination of Meta Pixel + server-side CAPI + unique UTM parameters per creator makes it possible to reconcile Meta and GA4 data, and to isolate the contribution of each piece of content in the conversion journey.
The 7-day click + 1-day view window is the Meta standard for UGC e-commerce. It should be adapted to the product's purchase cycle: shorter for impulse purchases, longer for products that require more consideration.
Apply the Kill / Sustain / Scale framework: scale creators with ROAS above the target threshold and CPA below the defined target, maintain those who feed paid via whitelisting, and stop the others without waiting.
ROAS measures the revenue generated per euro spent on advertising. ROI integrates all costs (production, usage rights, gifting, agency fees, media) to evaluate the overall profitability of the campaign. ROAS drives daily optimisation; ROI evaluates the campaign in its entirety.
