How to write a product catalogue that marketplaces and Google can read

Search boxes and filters read your catalogue before any buyer does. Fill titles, attributes and variants from one master sheet, the same way on every channel, and the right buyer's search will find the listing.

You list the same hand-tufted rug on Amazon, Flipkart and your own store. It sells on one and sits on the other two. The product is identical, so the listing is the problem: a size field left blank, a colour typed as "Peacock" where the filter only knows "Blue", four colours entered as four unrelated products. Fill titles, attributes and variants from one master sheet, the same way on every channel, and the search box and filter panel can match your product to the buyer already looking for it.

Who reads your catalogue before a buyer does?

Software does. A marketplace's search, its filter panel and Google's shopping results all read your listing as a set of fields, not as a page. A buyer taps "Wool", "5 x 8 ft" and "Blue", and sees only listings whose fields hold exactly those values. Your careful description often goes unread. If the size field is empty, the rug is invisible to everyone who filtered by size.

Then the person arrives, reads the first line of the title on a small screen and decides whether to tap. The title has to carry the facts they filtered on, in their words.

Build one master sheet before you touch a seller panel

What you need is a single spreadsheet that holds every fact about every product, and one house rule: nobody types a value straight into a seller panel. Each channel's upload file is filled from the sheet. When the sheet is wrong, it is wrong everywhere, and it gets corrected once.

ColumnWhat goes in itThe rule
SKUYour code for this exact itemOne code per size and colour, never reused
Parent IDThe code shared by every variant of one designSee the variant rule below
Product typeThe buyer's word: "living room rug", "steel tiffin box"Not your trade's word
Deciding attributeThe one fact the buyer chooses onGoes into every title
MaterialFabric, metal, plastic gradeOnly what your supplier's bill or a test supports
Colour, filter valueThe value from the channel's colour listPicked from your own fixed list, mapped per channel
Colour, display name"Peacock", "Rust", "Bottle green"Free text, shown to the buyer
Size as sold"5 x 8 ft", "King", "500 ml", "Pack of 3"Matches the channel's size list; measured from your product, not copied from the supplier
In the boxEverything the buyer receivesAnti-slip pad, lids, cables, the manual
GTIN or barcodeThe number printed on the pack, if the product has oneLeave blank for handmade or private-label goods; never invent one
HSN codeAs classified by your CANeeded for GST invoices; never guessed
Title, one column per channelYour site and each marketplaceBuilt from the columns above, never typed fresh

A title formula that holds on every channel

Brand, product type, deciding attribute, size or pack, then variant. For the rug: "[Brand] Hand-tufted Wool Rug for Living Room, 5 x 8 ft (152 x 244 cm), Geometric, Peacock".

The deciding attribute changes with the product, and choosing it is most of the work. For a mixer grinder it is the wattage and the number of jars. For a phone cover it is the exact phone model. A pressure cooker buyer chooses on capacity and whether the base works on induction. Scroll through the questions buyers send you; whatever they ask most belongs in the title.

Cut "best", "premium quality" and "hot sale". They push the size off a title the phone screen cuts short.

On your own site, give Google a fuller title and a description in your own words. Pasting the marketplace description there puts you in competition with your own text on a far bigger website.

When to group variants, and when to split them

Group sizes, colours or pack counts under one parent when a buyer would compare them side by side and nothing else changes. Split them into separate products when the material, the design or the contents of the box change, because a review of one would mislead the buyer of the other.

Sellers get this wrong both ways. Four colours listed as four products scatter the reviews. A wool rug and a cheaper viscose version under one parent collect complaints about "the pile" that apply to only one, and the next buyer cannot tell which.

In the feed you send to Google, give every variant its own SKU, price and photograph, then tie them together with the feed's group ID. A blue rug shown in a red photograph is a return waiting to happen.

For example: a tufted rug unit in Bhadohi

Imagine a family unit in Bhadohi (an invented case, with invented figures) selling hand-tufted wool rugs on two marketplaces and a Shopify store. Three people list products, each from memory. One design is "Peacock" on the store, "Teal" on one marketplace and "Multicolour" on the other. The second marketplace asks for size in centimetres. The team had only ever sold in feet, so they left it blank. Every colour is its own listing.

The rugs are good. On the second marketplace they vanish when a buyer filters by size, and on both they vanish when the filter is "Blue".

None of it needed a new photographer. The team built the master sheet and a colour map: display name "Peacock", filter value "Blue" everywhere. They measured every finished rug in both units instead of converting the feet on the order slip. Each design's colours went under one parent. Every channel's file is now uploaded from the sheet, so the next correction happens once. It was not clean at first: about 40 of the 300 listings (invented figures) were rejected on the second marketplace for a unit mismatch and had to be fixed by hand.

When the catalogue is not your problem

Seller dashboards on the larger marketplaces show how often each listing was seen and clicked. A listing that is seen and clicked but not bought has a price, photograph, review or delivery problem. If it is barely seen, start with the catalogue. With ten products on one marketplace, skip the full sheet: fix the titles, fill every filter field and stop.

What to do this afternoon

Pick the products that sell on one channel and stall on another. Open each one on every channel where you list it, side by side, and write down every value that differs: colour names, sizes, what is in the box, the order of words in the title. That list is the first draft of your master sheet. How buyers search in each product category is covered in the e-commerce sales and marketing section, and e-commerce and marketplace marketing is the service that sits around it.

Questions

Questions owners ask.

Should my product titles be the same on Amazon, Flipkart and my own website?
The facts should be identical; the order and length can differ. Keep brand, product type, the deciding attribute and the size in every title, then fit the wording to each channel's template. What must never differ is a value. A rug sold as 5 x 8 ft on one channel cannot be 6 x 9 ft on another.
Do I need a GTIN or barcode for every product?
Not always. Branded goods sold widely carry one, and Google and the larger marketplaces have a field for it. Handmade and private-label goods may not have one, and each platform has its own route for that, so read its current help page before you pay for barcodes.
How many attributes should I fill in?
Every field a buyer could filter on, and every one you can state truthfully. Leave a field blank rather than guess. A wrong fabric or a wrong wattage brings a return and an angry review, and both cost more than a missed filter.
Can I use the supplier's product description?
Use it as a source of facts, not as your copy. Check every number against the product in your hand, then write the description in your own words. The same supplier text is probably sitting on dozens of other listings, and some of its claims may not be true of your batch.
