How to Vet UGC Creators Before Paying (Using Competitor Ad Data)

How to Vet UGC Creators Before Paying (Using Competitor Ad Data)

Stop picking creators from portfolios. Start finding them in your competitors' ads that are spending $10K/day.

The Problem with Portfolio-Only Vetting

Most guides tell you where to find UGC creators. They list platforms, discuss pricing, and show you red flags in a portfolio. It’s a discovery-first approach.

You see follower counts, production quality, and a reel that looks good. You hire them. You pay $300–$800 for a batch of content.

Then you run the ads.

The CPM is high. The CTR is low. The ROAS never hits target. You wasted the creator fee and the ad budget testing content that doesn’t convert.

Follower counts and aesthetics lie. A creator with 100K followers might make beautiful content that never sells. A creator with 5K followers might be the secret weapon behind a brand spending $50K/day.

The risk isn't just the creator fee. It's the lost time, the burned ad budget, and the delayed launch. You need a way to see which creators are already driving sales for brands like yours — before you ever send a DM.

Using Competitor Ad Data as Your Source of Truth

A portfolio shows you what a creator can make. An ad library shows you what a creator has made that a brand decided to spend real money on.

That’s the difference. One is potential, the other is proof.

When a brand duplicates a UGC video ad 15 times and runs it for 60 days across three countries, they’ve validated that creator’s performance with thousands of dollars in ad spend. They’ve done the testing for you.

Your job is to find those ads and reverse-engineer the creator.

The scaling signals you’re looking for:

• Long runtime. An ad running 25+ days has survived the initial testing phase. It’s profitable, or it would have been killed.
• High frequency. One ad duplicated 5, 10, or 15 times is a brand scaling a winning creative. They’re pouring budget into it.
• Cross-platform presence. The same creator appearing in a brand’s TikTok Spark Ads and Meta video ads is a strong signal.
• Spend data. In the EU/UK, you can see real daily spend. EUR 1,000+/day on a single UGC ad is a cash cow.

These signals don’t exist in a portfolio. They only exist in the ad platforms where money changes hands.

Step 1: Find Competitors Running UGC Ads

Open Brandsearch Discovery.

Set your platform filter. For UGC, that’s usually Meta and TikTok. UGC thrives on these platforms.

Use the format filter. Select Video.

Now, search for your product category or niche. Be broad at first — “skincare”, “fitness supplement”, “pet toy”.

The goal isn’t to find one perfect ad. It’s to find brands in your space who are actively running UGC-style video ads.

Scroll. Look for the tell-tale signs of UGC: someone holding the product in their home, talking to the camera, raw cuts, text overlays. It feels native, not produced.

When you find one, click into the brand. You’ll land in Brandsearch Brand Analysis.

Step 2: Analyze the Brand’s Creative Arsenal

You’re now inside a competitor’s ad strategy. Go to the Hooks tab.

This tab isolates the first 3-5 seconds of every winning video ad. It’s where you’ll see patterns.

Are most of their top-performing videos from the same 2-3 faces? That’s your shortlist.

Next, go to the Scripts tab. This shows full AI-transcribed ad scripts. Scan them. You’re looking for consistency in delivery, tone, and hook structure across multiple ads from the same creator.

A creator who appears in 5 different scripts, each with a different hook but the same authentic delivery, is a recurring asset.

Finally, check the Creative Tests tab. This groups ads by visual strategy. Look for a cluster labeled “UGC Creator - [Name or Style]” or “Authentic UGC”. This tab tells you how the brand categorizes and tests their creator content.

Step 3: Vet the Creator’s Performance in the Wild

You’ve found a brand and identified a recurring creator in their ads. Now, you need to validate that creator’s impact.

Go back to Discovery. This time, search for the brand name you just analyzed.

Add a filter for Running Days: 25+. This filters out flash-in-the-pan tests and shows you what’s working long-term.

Now look for the creator’s face. Scroll through the brand’s ad history.

What you want to see:

• Multiple ads featuring the same creator.
• Ads with long runtimes (60+, 90+ days).
• If in the EU/UK, check the spend column. Is there real budget behind these ads?
• Look at the Rank. An ad climbing in rank (e.g., from 1200 to 300) is being scaled aggressively.

A creator appearing in one ad that died after 4 days is a test. A creator appearing in 8 ads, all running 40+ days, with one ad holding a top 500 rank, is a proven winner.

The ultimate signal: find the same creator creating ads for multiple non-competing brands in your niche. That creator understands how to sell a category, not just a single product.

Red Flags No Portfolio Will Show You

Portfolios show the best work. Ad libraries show everything — the winners, the tests, and the corpses.

Static Ads vs. Scaling Ads.

A UGC ad that’s been running for 90 days but sits at a flat, low rank (e.g., 5000) might be coasting. It’s not necessarily bad, but it’s not being scaled. A UGC ad that jumped from rank 2000 to 400 in 30 days is on fire. Prioritize creators behind the climbing ads.

Creative Fatigue Signals.

In the Brand Analysis overview, look at the ad scaling chart. If a brand’s ad count spiked 60 days ago with UGC creatives and has been flat or declining since, those creatives might have fatigued. The creator’s style might be played out for that audience.

The One-Hit Wonder.

A creator who has one fantastic ad that scaled, but whose other 5 ads for the same brand died in under a week, is inconsistent. You want creators with a repeatable process, not one lucky shot.

How to Contact and Brief a Vetted Creator

You found a creator in a competitor’s scaling ads. Now what?

Don’t lead with “I saw you in my competitor’s ads.” It’s awkward.

Find their social handle (usually in the video watermark or easily searchable). Look at their profile. They likely have a “Brands I’ve Worked With” highlight or a link to a UGC platform.

Your outreach is simple: “Loved your work for [Competitor Brand]. We have a similar product in the [Niche] space and think you’d be a great fit. Here’s what we’re looking to test.”

Because you’ve seen their converting work, your brief can be specific. “We saw great performance on problem-solution hooks for [Competitor]. We’d like to test a similar angle focusing on [Your Unique Angle].”

You’re not guessing. You’re giving them a direction they’ve already proven they can execute successfully.

Building a System, Not a One-Time Hire

Vetting one creator is a task. Building a pipeline of proven creators is a system.

Create a Brandsearch Swipe File folder called “UGC Creators”.

When you’re researching competitors in Discovery or Brand Library and spot a winning UGC ad, save it to that folder. Add a note with the creator’s handle and the competitor’s name.

Over two weeks of casual research, you’ll build a list of 10-15 creators whose faces are associated with scaling ads in your niche. That’s your talent pool.

Refresh this list every quarter. Creators burn out, styles change, and new stars emerge in the ad data.

The Free Starting Point

You don’t need a paid tool to start thinking this way.

Install the free Brandsearch Chrome Extension.

When you land on a competitor’s Shopify store, click the extension. You’ll instantly see their traffic, top ads, and tech stack. Click “View All Ads” to jump into their ad library. Look for the UGC videos. See who’s in them.

It’s a zero-cost way to shift your mindset from portfolio-scrolling to ad-data-scouting.

The Bottom Line

Picking UGC creators from a portfolio is guessing. Picking them from your competitors’ scaling ad campaigns is strategy.

The data exists. The ads are public. The spend signals are there.

Your next winning creator isn’t on a marketplace page. They’re in the ad library of a brand that’s already paying to scale their content every single day.

Find them there, and you pay for performance — not potential.
