The frame for this comparisonProduct data is a practice, not a project.
With a styling engine already reading your feed, first-pass fill is the easy part — the hard part is the second pass, nine months on, when the assortment has turned over and the vocabulary has drifted since anyone last looked.
01
Ground it
Mine every spec from every source.
Every value traced to a document you can open. The catalog is only as honest as what it was built from.
02
Align it
Aim the catalog at the buyer who actually buys.
Grounded data still loses if it answers questions nobody asked. Alignment is what turns specs into conversion.
03
Keep it alive
Product data is a practice, not a project.
Markets move, suppliers reissue, buyers change what they ask for. A catalog that is right in March is wrong by August unless something is watching.
