Google has added Category and Sale Duration properties to its merchant listing structured data, giving retailers a way to feed more precise product information into search. It is a small, free ranking signal that most businesses will ignore. The ones that implement it get more accurate product visibility for the cost of an afternoon.
Structured data is you telling the machine exactly what you sell. Skip it and you are letting the machine guess, and the guess is rarely in your favour.
Google has added two new properties to its merchant listing structured data. Category and Sale Duration. They give retailers a way to hand Google more precise information about a product, so it can be matched and shown more accurately in search results. In the same week, Google quietly dropped the "Next" from Merchant Center Next. It is now just Merchant Center.
Structured data is one of the least glamorous jobs in marketing and one of the most quietly effective. It is the difference between Google guessing what your product is and Google knowing. These two new fields let you be specific about category and about when a sale runs, and specificity is what gets a product surfaced to the right search.
Why it matters
As more of search shifts to AI answers and automated product surfaces, the machines doing the matching can only work with what they can read. A product with clean, complete structured data is legible to those systems. A product without it is a blur, and a blur does not get cited, matched or shown.
For Australian retailers, this is a rare thing. A ranking improvement that costs time, not media budget. Most competitors will not bother, because it is technical and unglamorous and nobody gets praised for it. That is exactly why doing it is an edge.

What to do about it
Add the new Category and Sale Duration properties to your product markup. It is a small job with a direct payoff.
Audit your existing structured data first. Missing or broken markup is costing you visibility you already paid to earn with the product.
Treat structured data as feeding the AI layer, not just classic SEO. The systems reading your pages need it to cite you.
Get the basics complete before the extras. Price, availability and product identifiers matter more than any single new field.
Assign it to someone and check it shipped. Technical SEO dies in the gap between "we should" and "we did".
This is not a headline change. It is a small, free lever that improves how accurately your products show up in a search environment that increasingly runs on what machines can read. The businesses that keep their structured data clean will quietly out-surface the ones that never got around to it.
