Already have a link? Check whether it still matches. Comparing several items? Build a small shortlist. Unsure about the photos? Use the category guide. Getting irrelevant results? Simplify the search.
Choose your situation
What are you trying to solve?
Each path ends with a concrete action, so you can return to the product decision instead of collecting more reading.
I already have a link
Confirm the current title, option, images, source, and destination before comparing the item.
Check a shared link →I need to judge photos
Use different inspection points for shoes, clothing, bags, watches, and electronics.
Read QC photos →I have too many options
Reduce the list with a time-boxed workflow and an explicit stop rule.
Build a shortlist →Task-based guides
Read for the next decision
These are independent guides. They do not verify listings or provide transaction support.
How to read QC photos by product category
Separate identity, shape, construction, sizing, and packaging evidence instead of judging a photo set by image count.
Open the QC guide →How to check a shared product link
Confirm that the route, listing, option, and source still describe the same item before the link enters your shortlist.
Check a shared link →A 15-minute product-shortlist method
Move from a long sheet to two or three explainable candidates with timed passes and stop rules.
Start the workflow →Turn a vague spreadsheet search into a useful query
Build queries around product family, one descriptor, one evidence need, and—only when useful—a source marketplace.
Repair the search →Understand platform names in shared spreadsheets
Find out why an old platform label can stay attached to a link, what that label may explain, and what still needs checking on the live page.
Read the platform guide →How to use a Tangbuy spreadsheet
Treat each row as a research prompt and learn what should happen before an external product page is saved.
Read the main guide →Understand weight before comparing prices
Separate item weight, packed weight, dimensional risk, route inputs, and estimates that still need confirmation.
Review shipping weight →Leave each guide with one concrete check
Before you return to the product list, decide what you will inspect next: a measurement, a missing photo angle, the current option, the original source, or the packed weight. If the guide did not narrow the question, choose a more specific route above.
