For Creators
A UGC portfolio has one job: convince a stranger with budget that your videos will work for their product. Most portfolios try to do that with volume and aesthetics — a wall of thumbnails and a nice Canva layout. But the person reviewing it is asking a narrower question than "is this person creative?" They're asking "will this hold my audience's attention?" Build the portfolio that answers that.
Reviewers skim. They'll open one or two videos, watch a few seconds, and form a judgment that the other ten videos never get to revise. That means a 12-video portfolio is riskier than a 5-video one: more chances to open the dud. Pick 4–8 pieces, lead with your strongest, and organize by what a buyer shops for — format (testimonial, demo, unboxing) and product category — so a skincare brand lands on your skincare work in one click, not after scrolling past your gadget reviews.
Brands buying UGC for paid social live and die by the opening — viewers decide within seconds whether to keep watching, and the reviewer knows it. So they'll judge your portfolio the way the feed judges an ad: by the hook. Before a video goes in the portfolio, watch its first three seconds muted, out of context. If it doesn't earn the next three, it either gets re-cut or stays out. Your portfolio should be a highlight reel of openings as much as a body of work.
Here's the asymmetry to exploit. Every portfolio claims the work performs; almost none can show it, because view counts from your own account measure your followers' loyalty, not the content's pull with strangers. Run each portfolio piece through PreTestAds: you get a predicted-attention percentile against 76 top-performing TikTok ads — scored by a neural model trained on brain-response data — plus a second-by-second attention curve. Put the number next to each video: "Top-quartile predicted attention vs. benchmark." A reviewer who has skimmed fifty walls of thumbnails stops at the one portfolio with measurements on it.
An empty portfolio isn't a blocker — unproven content is. Make spec ads for products you own and use, in the formats brands buy, and score each one before it earns a slot. The score does double duty for a beginner: it substitutes for the client results you don't have yet, and it's a private quality filter — a spec piece that scores weak teaches you to fix the opening before any brand ever sees it. Label spec work honestly as spec; paired with a strong score, it reads as initiative, not padding.
The score predicts attention and engagement with the content — it doesn't promise conversions, and your portfolio shouldn't say otherwise. Caption the numbers as what they are ("predicted attention vs. a benchmark of top-performing TikTok ads") and let client outcomes, where you can share them, carry the sales claims. Precision is the brand: the whole point of a measured portfolio is that you're the creator who doesn't hand-wave. Done well, the portfolio, your pitch, and your rate conversation all make the same argument from the same evidence — and if you sell through apply-to-brief platforms, the same scored portfolio is what wins the selection.
Score your portfolio pieces and show brands attention percentiles and curves — first analysis free, no card.
Score Your PortfolioA short intro, 4–8 videos organized by format (ad, testimonial, unboxing, demo) and category, and — the part almost everyone skips — evidence each piece performs: an independent attention score against a benchmark of top-performing ads, hook-strength numbers, and client results where you have permission to share them. Less is more: your weakest video sets the impression, not your best.
Spec ads: make real ads for products you already own, exactly as if the brand had briefed you. Then score them with an attention-prediction model so each piece carries evidence, not just effort. Two or three spec videos with strong scores against proven TikTok ads beat a dozen unscored ones — you're demonstrating both the craft and the result.
Fast and skeptically. They watch the first three seconds of one or two videos, check whether you've worked in their category, and look for any signal that separates you from the last fifty portfolios. View counts from your own account don't count for much — they came from your warm audience. Independent, content-level evidence that your videos hold attention with strangers is the signal they rarely see.
