A roundup post holds several products in one frame or one gallery, and it converts better than a single-product post because it gives the shopper a choice inside your recommendation. LTK’s own guidance for top-performing posts is “4-8 products from 1-2 brands” with links to exact products (company.shopltk.com, accessed August 2026). The format is settled. Producing it is not.
The problem is cohesion. Six products bought over three months were photographed on three surfaces, in three colour temperatures, at three distances. Put them in one grid and the grid reads as a scrapbook. Shoppers scroll past scrapbooks.
Most creators solve this by pulling the brand’s product photos, which are consistent because a studio made them. That fixes the look and creates a rights problem, because those images belong to the brand.
This covers why cohesion moves the post, where your product images can legitimately come from, and how to bring eight mismatched shots to one set of lighting and staging.
Key Takeaways
The roundup format is what LTK recommends. Top-performing posts hold 4-8 products from 1-2 brands with exact product links (company.shopltk.com, August 2026).
Cohesion is the whole job. The products are fine. The mismatch between the photos is what makes a grid look amateur.
Match four things, in this order. Background, light direction, colour temperature, scale. Get those right and mixed source quality stops showing.
Brand photos are not a shortcut. LTK requires you to have the right to use any content you share, “even if it’s publicly available elsewhere” (company.shopltk.com, August 2026).
Shoot once, restage many times. One clean phone capture per product becomes flat lays, styled scenes and seasonal versions without touching the product again.
Roundups rerun. “Autumn boots” becomes “winter boots” with the same staging and different products. The second one costs a fraction of the first.
Commercial use starts at Pro. Affiliate posting earns commission. In DesignerBox the commercial license begins at Pro ($35/month), and the free plan watermarks output.
Why the roundup outperforms
Three things are happening in a roundup that a single-product post does not get.
Choice inside a recommendation. A shopper who does not want the black one may want the tan one. One post, several chances at the click.
More links, one piece of production. LTK’s cookie windows run 7 to 30 days across brand partners, “generally between 7-14 days on average” (onbrand.shopltk.com, accessed August 2026). Every product in the frame is a separate chance to open that window.
Saveable. A roundup is a reference. Shoppers save it and come back, which is a different behaviour from a like and a better predictor of a purchase.
The category economics support the effort. LTK groups brand partners by net commission rate: high is 11% or above, medium is 7% to 11%, low is 7% or below (onbrand.shopltk.com, August 2026). On the Mavely side, Later reported creators earning $3 million across the four-day Black Friday and Cyber Monday window in 2025, against $50 million in sales (later.com, December 2025). Roundups are what get published into those windows.
Roundups also carry the best return per unit of work on a commission programme, which is why they sit at the centre of the Mavely creator content workflow.
Where your product images can come from
Four sources, and they are not equivalent.
| Source | Can you post it? | Notes |
|---|---|---|
| Your own photo of a product you own | Yes | The only source with no conditions attached |
| Brand media kit or creator asset library | Yes, per its terms | Real permission. Read the usage terms, they often exclude paid promotion |
| Product-page or Instagram image from the brand | No | The brand’s copyright. An affiliate agreement is not an image license |
| Another creator’s photo | No | Their copyright, and LTK’s guidelines name this directly |
The full rules picture, including what LTK’s Community Guidelines say about AI and about content rights, is in AI content for LTK creators.
The practical consequence: your own capture is the raw material for almost everything. It does not need to be good. It needs to be yours, in focus, and lit well enough that the product’s real colour is visible.
The four things that must match
Cohesion is not a taste question. It is four measurable properties, and fixing them in this order is fastest.
1. Background. The single biggest offender. Eight products on eight different surfaces cannot be rescued by anything else. One surface across the set, or one surface family (all warm neutral, all stone, all linen).
2. Light direction. If half the products cast shadows to the left and half to the right, the eye reads it as a collage. Pick one direction and restage the outliers.
3. Colour temperature. Kitchen tungsten against window daylight is the difference between orange and blue on the same white shirt. Normalise the set to one temperature, usually daylight.
4. Scale. A handbag and a lipstick shot at the same frame size makes the lipstick look enormous. Keep relative size honest, then adjust the crop.
Get the first two right and mixed source quality mostly stops registering. Get all four and a phone-shot set reads as a studio set.
How to run it
Capture once per product. Plain surface, window light, one angle. Keep the file. This is the asset you restage forever.
Strip the background. Cutting every product out of its original setting is what makes a single background possible. It also lets you rebuild scale independently of how far away you stood.
Rebuild one scene for the whole set. A single surface, a single light direction, all products staged into it. This is the step that converts eight photos into one photograph.
Generate the variants. Once the set is coherent, alternate crops, a vertical version for Stories and a seasonal restyle come off the same source. LTK favours 9:16 for feed posts because it pairs with Stories and holds the screen longer.
Save the recipe. Surface, light, palette and staging written down or saved as a workflow. That is what makes next month’s roundup an assembly job.
In DesignerBox this maps onto the Flat Lay Studio, Background Remover and Styled Scene Generator apps, which run on the same product photo you uploaded. The background removal and the restaging are the load-bearing steps. Deeper technique for the format itself is in flat lay photography, and if your source captures are rough, low-resolution product images covers what can and cannot be recovered.
Roundups that rerun
The payoff in this format is not the first post. It is the fourth.
A roundup is a template with the products swapped. “Autumn boots under $150” and “winter boots under $150” are the same surface, the same light, the same crop, the same caption skeleton. Once the staging exists, a new roundup is a new set of cutouts dropped into a scene that already works.
Three template families cover most of a year:
- Seasonal. Same staging, new season’s products. Four posts a year per category
- Price band. “Under $50”, “under $100”. Same look, different tier
- Occasion. Gifting, travel, back to school. Recurring on a calendar you can see coming
The saved-workflow mechanic is what makes this cheap. Content batching covers running several of these in one sitting rather than one at a time, and Instagram product photos covers adapting the same set for the feed.
What this does not fix
Bad product selection. A coherent grid of products nobody wants is a well-photographed miss. The picks carry the post.
Colour accuracy on a restaged product. Restaging can shift a product’s rendered colour, and returns come out of your commission. Check the product’s real colour against the original capture before publishing, especially on apparel and makeup.
Products you do not own. Nothing here generates a legitimate image of a product you have never had. That is the constraint, and it is also the reason the output is safe to post.
Attribution beyond the cookie. A saved roundup that converts in six weeks converts outside most brand cookie windows, which average 7 to 14 days on LTK. Evergreen roundups earn less than their traffic suggests. Repost them.
FAQ
How many products should an affiliate roundup post include?
LTK’s guidance for top-performing posts is 4 to 8 products from 1 to 2 brands, with links to the exact products (company.shopltk.com, August 2026). Fewer than four gives the shopper little to choose from. More than eight makes each product too small to judge on a phone.
Can I use the brand’s product photos in my roundup?
Only with permission. LTK requires you to have the right to use any content you share, including images, “even if it’s publicly available elsewhere.” Some retailers grant asset rights in a creator media kit, and those terms often exclude paid promotion. A product-page image with no stated permission is the brand’s copyright.
How do I make products photographed at different times look consistent?
Match four things in order: background, light direction, colour temperature, then scale. Removing every product from its original background and restaging the whole set into one scene fixes the first two at once, which is where most of the visible improvement comes from.
What image size works best for LTK roundups?
LTK favours 9:16 because it pairs with Instagram Stories and keeps the post on screen longer while shoppers browse. Produce the set once and export a vertical crop alongside the square.
Do roundup images need an AI disclosure?
LTK does not require a label for ordinary AI editing such as background replacement or relighting. Some platforms require synthetic-media labels for photorealistic content, and those rules apply wherever you post. Your commission disclosure is required regardless, under both LTK’s guidelines and the FTC’s Endorsement Guides.
Which DesignerBox plan covers affiliate roundups?
Pro ($35/month) or higher, because affiliate posting earns commission and the commercial license starts at Pro. The free plan includes 112 credits and watermarks output, which makes it a test rather than a publishing tier. Details in DesignerBox pricing explained.
