Who this is for
Merchant with thousands of products that arrived without a category in your tree.
A catalogue import left products uncategorised and sorting them by hand would take days.
The result
Each product gets one leaf category from your list or the value 'review', never a category that is not in your tree. On products you labelled and we have not seen, the share placed correctly is reported, and doubtful products go to review and count as misses.
What is included
- One product file of up to 20,000 products and a category tree of up to 300 leaf categories you own
- One leaf category or 'review' for each product
- A held-back test on 50 products you label
- Per-category results where there are enough held-back products, and a list of weak categories
- The script and the steps to run it
You receive
- The product file with a category or 'review' on every row

What is not included
- Creating, renaming or merging categories
- Resolving disputes about what a product is

What we need from you first
- The category tree as a list, and how many leaf categories it has
- How many products are uncategorised
- No real records, personal data or credentials in the first enquiry
Never send passwords, keys, customer records or confidential code in the first enquiry. Secure handover is agreed after scoping.
How we check it is done
- Of the 50 held-back products, at least 45 get the category you labelled; review counts as a miss. 45 of 50 shows the true rate is at least 80% with 95% confidence. The report also shows the score from giving every product the most common category, and the pass counts only if our score beats it by the margin agreed in writing.
- Every category in the output exists in your tree. One invented category fails the whole test.
- 5 products that fit no category, which you add and we do not see beforehand, land on 'review'.
- Per-category results are reported for categories with at least 5 held-back products, and any of those with fewer than 60% correct is listed as weak; other categories are listed as too few to judge.
You inspect the results and the review list, and sign off in writing. Payment follows sign-off.
When we would stop or decline
- The category tree is disputed inside your team
- You want new categories invented
- A marketplace taxonomy applies that you cannot supply
- The two labellers agree on fewer than 17 of 20
Questions
Will it create new categories?
No. Only categories in your tree are used. Anything doubtful goes to 'review'.
How is accuracy checked?
On 50 products you labelled and we did not see. The result describes products like the sample.
Do I need this for Google Shopping?
Google says the category is optional. Check what each of your channels needs first.
