Key Takeaways
- 1For a limited budget, pay a freelancer for production skills you lack rather than choosing a larger package of deliverables.
- 2Fund the test with an advertising budget you can afford to risk, separate from production expenses and money required by existing profitable ads.
- 3Compare purchase costs before raising budgets for refreshed edits made with unused reactions and different questions, rather than just new captions on the same footage.
Street interviews turn product questions and reactions into ad creative. Plan product-specific questions, a lean shoot brief and a purchase-cost review.
Street interview ads are video ads built around a presenter asking people about a product or everyday problem. For a small store, use an attention-grabbing opening, add a clear call to action that tells viewers what to do next and compare different edits on Meta.
Creative rules for street interview ads
For e-commerce, consider street interview ads as a video format to test. Meta says videos can improve ad recall, boost engagement, build trust, increase sales and provide education. Build your interview around a question that connects the product to something a shopper cares about, such as convenience, taste or ease of use.
- Start the edit with the product question or a genuine reaction, then show what the participant is reacting to.
- Ask what the participant notices about the product without suggesting an answer or telling them which feature to praise.
- Ask whether the participant has used the product before filming. Label a new reaction as a first impression, and avoid using it to imply experience over time.
- Connect the response to a visible demonstration of the feature discussed. End with a call to action that leads to a page featuring the same product.
Sample script: “What would make you choose this for your daily routine?” Follow the response with a product demonstration and the closing line, “Shop the daily essentials collection.” Replace the collection name with the destination you actually advertise.
For viral street interview ads, STRAdvert defines “viral” as an organic post or paid ad that reached a large audience and produced a clear commercial outcome for the advertiser. Use that framing to keep the discussion about sales; don't let a viral label replace purchase reporting.
Write the question, opening and call to action before arranging the shoot.

A lean shoot brief for a small store
For interview videos, Meta's 2018 mobile-video announcement recommended aspect ratios of 1:1 and 4:5 for feed, 16:9 for in-stream and 9:16 for stories.
Plan your framing so faces and the product remain visible across those crops. Preview each crop with captions and the placement's interface visible, and adjust framing so important faces, product details and text stay clear.
Your shoot brief should specify the product, question, equipment, production responsibilities and deliverables before you commit money. Keep the concept narrow enough that you can explain the product without a long interview.
| Shoot essential | Put in the brief |
|---|---|
| Product and concept | Name the item, buying objection and question the interview should address. |
| Recording equipment | Bring a phone or camera, a microphone and headphones to check spoken audio. |
| Location | Pick a place where you can hear answers clearly and show the product without distracting clutter. |
| Participants | Name who will approach participants and explain the planned advertising use. |
| Footage and edits | Ask for raw footage, separate responses and edits with different openings. Specify the placement crops and caption positioning in the brief. |
Before filming, assign the production tasks below. Ask a qualified lawyer to review permission to film participants and use their footage in advertising for your location and intended markets.
- Choose who will interview participants and demonstrate the product.
- Assign someone to collect and store the completed documentation before recording or using participant footage.
- Choose who will collect the raw footage and check that edits match the participant's answers.
Use DIY production when you can handle public interviewing, sound and editing. Hire a freelancer for the skill you lack; consider an agency when you need recurring production managed for you.
For a limited budget, prioritize the missing production skill over a larger package of deliverables. Ask for a quote that lists footage, edits and production responsibilities before committing to the shoot.

A purchase-focused Meta campaign test
Compare your interview edits by recorded purchases and ad spend per purchase. For purchase-focused ads, use the sales objective and send viewers to the product page that matches the interview.
Before interpreting zero purchases or comparing purchase costs, follow StillFiring's advice: put a real purchase through and confirm that it appears in the ad platform's own reporting; a green checkmark or an app saying “connected” is not proof that tracking works. If that purchase does not appear, resolve the tracking problem and repeat the check before comparing purchase costs.
Compare them over the same reporting period, and keep the settings used to credit purchases to ads consistent across the comparison.
Set an advertising budget from what you can afford to risk, separate from production costs. Keep money needed for existing profitable ads outside that budget.
For your campaign report, record each edit's spend, purchases and advertising spend per purchase over the same reporting period. Judge your edits by purchases and ad spend per purchase, with your store's margin setting what you can afford to spend to acquire an order.
Hypothetical: a $50 order with $30 in product, fulfillment and other variable costs leaves $20 before ads. If you want to retain $5, your advertising allowance is $15 per purchase: $50 minus $30 minus $5.
Once purchase recording is confirmed and an edit has spent its planned allowance, pause it if it has no purchases or purchase costs above your allowance; prioritize affordable edits with lower purchase costs. If purchases remain sparse across the test, revisit the question, demonstration and offer before paying for more footage.

Fresh footage and creative longevity
Interview creative can cost more per result over time because people may engage less after repeated exposure, according to Meta's Business Help Center. It calls an audience seeing the same creative too many times creative fatigue.
Save unused reactions and different questions for future edits instead of relying on new captions over the same footage. Compare the refreshed edits' purchase costs before increasing their budgets. Review creative fatigue recovery options when purchase costs rise.
To compare fatigue timing, review purchase costs from launch for street interview edits and user-generated content (UGC) in your own account. Track when each format's purchase costs rise before deciding which footage to refresh.
According to Meta, opportunity score can include experimentally proven creative fatigue recommendations when eligible. The score itself, including a high score, does not reflect actual or future performance.
