Collection: Business of Catalogue Optimisation – Building Sales-Ready Catalogues
A client is preparing to add several hundred products to an established catalogue.
The new range is ready. Supplier information is available. Images have arrived. Categories need to be decided, attributes mapped and product pages prepared.
The project can look straightforward.
There are more products to add, so the agency needs to establish how those products will enter the catalogue and what needs to happen before they can be published.
Sometimes that is exactly the job.
If the existing catalogue is coherent and the incoming products contain the information required to follow it, growth may largely be a matter of applying an established approach to more products.
But an established catalogue contains more than product records.
Over time, it can accumulate useful product information and established ways of describing, classifying, comparing and distinguishing products.
A furniture catalogue may already record width, depth and height separately because those dimensions help shoppers compare products. An electronics catalogue may already record the compatibility relationships shoppers need to identify the right accessory or replacement.
The incoming products are therefore not joining an empty catalogue.
They are joining one that may already contain useful product knowledge built up across the existing range.
The question is what happens to that usefulness when the new range becomes part of it.
Consider a furniture retailer adding a new sofa supplier.
The supplier provides good product information.
Each sofa has a title, description, materials, images and dimensions.
Nothing obvious is missing.
But the retailer’s existing sofas record width, depth, height and seat height as separate pieces of information.
Those dimensions do more than complete the specification table.
They allow similar products to be compared consistently. They may support other parts of the catalogue where the shopper needs to understand whether a sofa will fit their space.
The new supplier provides one dimensions field:
2150 × 920 × 850 mm.
The underlying information is there.
But it is not yet represented in the same way.
If the agency simply imports what the supplier provides, every new product can still have accurate dimensions. The individual product pages may still look complete.
If those dimensions are imported in that form, the catalogue may no longer be able to use them consistently across the larger range.
The same issue can appear with compatibility information, materials, technical specifications, fit, capacity or any other product knowledge that has become useful beyond the field in which it first appeared.
An established catalogue therefore contains more than the information currently visible on its product pages.
It also contains decisions about which information matters and how that information needs to be represented if the catalogue is going to use it consistently.
Catalogue growth brings another set of products into those established information patterns.
Supplier information does not need to be poor for this problem to appear.
Two suppliers can describe the same useful characteristic accurately in different ways.
One may provide structured attributes. Another may place the same information in a specification table. A third may include it in descriptive copy.
Each product can be correct.
Yet the catalogue may not be able to use all three records in the same way.
Consider a catalogue selling cordless tools and accessories.
Its existing battery products record the tool platform they are compatible with. That information helps shoppers distinguish between batteries that may look similar but work with different equipment.
A new supplier range also provides accurate compatibility information.
But it appears as sentences inside each description.
Someone reading the product page can find the answer.
The catalogue, however, may no longer be able to use compatibility consistently across the full range without first restructuring that information.
Nothing necessarily went wrong during the import.
The new products arrived with the facts they needed.
The same compatibility knowledge is now represented differently across the catalogue.
That difference matters because catalogue growth can multiply it.
A few incoming products may introduce one competing convention. Several hundred can establish that convention across a substantial part of the range.
The catalogue has more products and more information than before.
But some of the product knowledge it previously handled consistently has become less consistently usable across the expanded catalogue.
This is why looking only at the completeness of the incoming products can miss part of the growth problem.
The agency also needs to consider how those products will participate in what the existing catalogue already helps shoppers do.
The existing catalogue should not automatically become the standard for the incoming range.
It may contain outdated terminology, duplicated attributes or structures that no longer serve the products well.
Protecting the catalogue therefore does not mean preserving every existing field, attribute or convention. The useful distinction is between the product knowledge and the structure currently holding it.
If existing sofas record the same dimension under several names, the agency should not reproduce those competing conventions across the new range. It needs to establish whether the dimension remains useful and how it should be represented across the expanded catalogue.
Growth does not create an obligation to preserve everything already there. It creates a reason to decide what should continue before additional products carry existing and incoming conventions across a much larger range.
That decision is made through the way the incoming products become part of the catalogue.
Adding 500 products does not only create 500 more records to prepare and publish. It also determines how those products will record and present product knowledge alongside the existing range.
If every new range introduces its own terminology, attribute structure and level of detail, those differences accumulate alongside the products themselves.
The first addition may be manageable.
The next supplier can introduce another approach.
A later range can add a third.
Eventually the catalogue may contain the right information in many places while making it increasingly difficult to use that information consistently across similar products.
That outcome is not inevitable.
An existing catalogue can grow substantially while remaining coherent.
Incoming supplier information can already match the catalogue’s requirements closely enough that very little intervention is needed.
But that can only be established by looking at both sides of the change.
What is coming in?
And what existing product knowledge does the new range need to support?
The first question tells the agency what the new range provides.
The second reveals whether the way that information is represented will continue, improve or weaken the usefulness already established within the catalogue.
Growing an established catalogue therefore means extending more than its product count.
It extends the way the catalogue represents useful product knowledge.
Before defining how incoming products should be structured, the agency needs to understand which existing product knowledge should remain usable across the larger catalogue.
When an agency is asked to grow an established catalogue, the scope should not be defined only by the number of incoming products or the fields available in the new source.
The agency also needs enough understanding of the existing catalogue to recognise the product knowledge that matters across the range.
That may mean identifying which existing distinctions support useful filtering, comparison, compatibility, classification or product understanding.
It may mean checking whether the incoming source contains the same underlying information and whether it represents that information in a compatible way.
And it may mean deciding that an existing convention should be improved rather than carried forward unchanged.
The appropriate response should remain proportionate.
If the catalogue already has a dependable approach and the incoming range fits it, growth may require little more than applying that approach consistently.
Where the new range represents important product knowledge differently, the agency needs to resolve how that knowledge should be carried into the expanded catalogue before volume turns the difference into a much larger condition.
The objective is not to delay catalogue growth or preserve the existing catalogue exactly as it is.
It is to understand what useful product knowledge the larger catalogue still needs to carry.
Before defining the scope and method of significant catalogue growth, agencies should establish which existing product knowledge needs to remain usable across the expanded catalogue and what will be required to make the incoming information support that use.
