Choose the sourcing intent first
A buyer searching for shoes, hoodies, bags or electronics should not save every attractive listing. Start with one intent: similar sneaker, warm hoodie, budget bag, small accessory, or electronics model. Then compare only the proof that matters for that intent. This keeps the shortlist useful instead of turning it into a random feed.
Remove rows that cannot become decisions
Delete duplicate styles, old screenshots, listings without option names and rows that cannot be verified with one QC request. A smaller shortlist with clear source proof converts better than a larger list where the buyer still has to guess.
What to compare between sellers
Compare the parts a buyer will actually see after warehouse arrival: product shape, color name, size label, included accessories and packaging. If two sellers use the same display image, choose the one with clearer option names or better detail photos. If neither seller provides a checkable detail, the row should remain research only.
