Which Pages Should I Update First When My Packaging Changes but the Product Itself Stays the Same?

Is it really the same product?

Check before you say so. GS1's rules for barcode numbers treat several packaging changes as changes to the trade item that need a new GTIN:

• A change in declared net content, such as 500 g to 450 g.
• A change of more than 20% in any physical dimension or in gross weight.
• Adding or removing a certification mark, such as kosher, UL or CE.
• A change to the primary brand on the pack.
• Adding, changing or removing a price printed on the pack.

If any of these apply, you have a changed product in data terms, and your pages should say what changed. If only the design, colours or artwork changed, the product and its barcode normally stay the same. A new size with the old price also needs careful wording: saying "same product" when the quantity fell will cause complaints.

In what order should you update pages?

Merchant Center's image guidelines ask for images that accurately display the entire product. So an old-pack main image is worth replacing once the new pack is what customers receive.

What should the sentence say?

Be exact about what changed and what did not:

"From March 2026, [product] comes in a new carton. The recipe, ingredients and 400 g size are unchanged. You may see both packs in shops for a few weeks."

Name the unchanged facts that shoppers care about: formula or recipe, ingredients, size, and price if unchanged. Avoid "New!" or "Improved" on the pack or page when only the packaging changed. Buyers and assistants take those words to mean the product changed. The FTC's advertising guidance notes that at least one FTC advisory opinion suggested a six-month limit on using "new" for a newly introduced product. A redesign is not a new product at all.

Why do assistants misread packaging changes?

• "New look" becomes "new formula". Summaries turn packaging news into product news unless the text rules it out.
• Two images, two products. Retailers showing the old pack and your site showing the new one look like two different items.
• Old listings disappear. If you remove the old-pack listing or change its URL, assistants may say the product was discontinued, a pattern explained in why Perplexity describes your product as discontinued when the product page is still live.
• Counterfeit worries. Shoppers who receive an unfamiliar pack ask whether it is genuine, and answers may repeat the worry if no official page explains the change.

What should the packaging FAQ answer?

• "Why does [product] look different?"
• "Has the recipe or formula changed?"
• "Is the size the same?"
• "Is the new packaging genuine?"
• "Why do shops have both versions?"
• "Can I recycle the new packaging?", if recyclability was the reason.

Keep the page live for at least as long as both packs are in circulation, and link it from the product page. It gives assistants an official page to cite when shoppers ask whether [product] changed.

What about retailers and marketplaces?

Retailers update images on their own schedules, often through product data services or supplier portals. Send new assets with the same identifiers, a short change note and the date the new pack ships. Check the listings that assistants cite most after two or three weeks. A retailer still showing the old pack is not a problem during the changeover. A retailer describing the product as "new formula" is, and needs correcting.

How should you handle the changeover period?

For a few weeks or months, both packs will be in shops, in customers' cupboards and in photos online. Plan for it:

• Show both packs on the product page, labelled "new packaging" and "previous packaging", until retail stock of the old pack has sold through.
• Keep one product URL. Do not create a new page for the new pack and delete the old one; that is what makes a product look discontinued.
• Brief customer service with the same sentence used on the page, so answers match.
• Tell reviewers and bloggers who feature the product, with images, so their updates use your wording.
• Set a date to review the page, when the old pack should be gone, and remove the old image then.

How do you test what assistants say?

Ask ChatGPT, Gemini, Perplexity and Google's AI features, several times each:

• "Did [product] change its recipe?"
• "Why does [product] packaging look different?"
• "Is [product] discontinued?"
• "Is the new [product] packaging real or fake?"
• "What size is [product]?"

Record whether answers describe the change correctly, and which sources they cite. Retest a month after the change, and again when the old pack has left the shelves. How to check that customers are sent to current pages is covered in how to test whether AI gives customers an outdated order tracking URL.

What might an illustrative case look like?

Consider an illustrative granola brand that moved from a plastic bag to a paper pouch with a new design, keeping the recipe and 500 g size. Its product page showed the new pouch with a "New!" badge, and the old listing was deleted. Within a month, assistants answered "Did [brand] granola change?" with "yes, [brand] recently launched a new recipe". They also described the plastic-bag version as discontinued. The brand removed the badge and restored the product page with both images. It added the sentence "Same recipe, same 500 g, new paper pouch", published a packaging FAQ, and sent new images to its retailers. A month later, most answers said only the packaging had changed, citing the FAQ.

What do people ask about packaging changes?

Do we need a new barcode for a new design?

Not for a redesign alone, in most cases. GS1's triggers that can apply to a packaging change are a new declared net content, a change of more than 20% in any dimension or gross weight, adding or removing a certification mark, a change of primary brand, and adding, changing or removing a price printed on the pack; a limited-time promotional pack keeps its consumer GTIN but needs new case and pallet GTINs. Check the rules for your change.

Should we keep old-pack images online?

As secondary images during the changeover, clearly labelled, then archive them.

How long should the packaging FAQ stay?

Until the old pack has left the shelves, and ideally longer. It costs little and answers a question people keep asking.
