Sign-off is your last chance to change it

Most of the money in an influencer campaign is committed at one moment: when you approve the video. The fee is agreed, the post goes out, and any budget you put behind it as a paid advert follows the cut you signed off. After that you can count views, clicks and sales, but you can’t make the video better.

This year that moment comes quickly. Black Friday is Friday 27 November, and most Christmas videos will be signed off in the weeks before it. A few days spent checking a video now are worth more than any report in January.

Why a good influencer video can still miss

Influencer content is very good at getting watched. Zappi’s analysis of 3,303 social video adverts found that videos influencers made with brands stood out far more than polished brand adverts. But the same videos did much worse at making viewers link them to the brand.

People remember the video and forget whose it was. What helped most was showing the brand’s own distinctive assets in the video: its colours, pack, logo or sound (+0.70).

That is exactly what a moment-by-moment read is for: it shows where attention falls away, so you can see whether the brand arrives before it does, while the video can still be re-cut.

So the question isn’t only “will people watch it?” It’s “will they know it’s ours, and will they want it?”

Five things to check before you approve

1. The first three seconds. Does something happen before the thumb moves on?
2. The brand, early and clearly. Is the product, pack or name on screen while people are still watching, and is it said out loud?
3. The message you briefed. Would a viewer repeat the one thing you wanted them to take away?
4. The influencer’s own voice. Does it sound like them, or like a script they were handed? Their audience can tell.
5. One clear next step. A promo code, a link or a place to buy, said and shown.

Three ways to test, from quick to thorough

Here is what a predicted read looks like, from our sample Creative Testing report:

Decide what each answer means before you test

A test is only useful if it can change the decision. Agree up front which result leads to which outcome:

• Approve the video as it is.
• Ask for a re-cut. Most often: bring the brand into the first few seconds, or shorten the opening.
• Move the budget to a stronger video.

Put one round of edits in the influencer’s contract, so a re-cut is part of the deal rather than a favour.

Then keep the result. Once the video is live, compare what the test said with what happened: views, clicks, sales through the influencer’s promo code and, for a bigger campaign, what it did for the brand. Over a season you’ll learn how far to trust each kind of test, and whose videos land.

Justify reads both sides of that once the video is live: what each influencer sold through their promo code or link, once your Shopify or WooCommerce shop is connected, and, if you run a Brand Lift study, what the campaign as a whole did for the brand, measured with real people against a group who didn’t see it.

Your Christmas checklist

• Put a test date in the plan two working days before each sign-off date.
• Ask for the cut you’ll actually post or boost, with sound.
• Check the five things above, then test.
• Agree one round of edits in the contract.
• Write the result down, and look at it again in January.

A few days now is cheaper than a lesson in January.
