First identify the page type
Source names describe ecosystems, not one consistent page format. The same spreadsheet may point to an image album, a single product, a seller storefront, a search page, or an agent-wrapped version of a marketplace URL.
Yupoo-style album
Usually image-led. Look for a product code, option note, recent date, contact or source clue, and a link that connects the album to a current item page.
Taobao or Weidian item
Usually a live listing with variants, a displayed price, seller information, images, and sometimes measurements. Confirm the selected option.
1688 listing
May use quantity tiers, multiple specifications, wholesale wording, or a price range. Check minimums and variants before reading the first amount as the item price.
Store or search page
Useful for discovery, but too broad to verify one row unless you can identify the exact item again.
Run the five-point match test
- Product type: Is it still the same kind of item?
- Visual identity: Do shape, color, design details, and main image agree?
- Exact option: Does the selected size, color, model, set, or quantity match the row?
- Details: Do the measurements, specifications, photos, and notes belong to that option?
- Price and status: Is the visible price tied to the same option and quantity, and does the listing appear active?
If one point fails, record it. If two or more fail, the row is usually no longer a fair basis for comparison.
Read the link as a chain, not a destination
A common route looks like this: spreadsheet row → directory or agent page → converted URL → marketplace listing → seller or album page. Information can change at each step. The title may be copied from an older listing, the default option may change, or the final page may be a broad search rather than the product.
Watch for option and price traps
| What you see | What may be happening | Useful next check |
|---|---|---|
| A surprisingly low amount | Lowest-priced accessory, deposit, smallest quantity, or different variant | Select the intended option and read quantity or tier wording |
| Main image matches, options do not | Listing changed or the row points to an old configuration | Compare current variant photos and remove the row if the option is gone |
| Several products on one page | Album, collection, or store rather than a specific listing | Find the exact code or source link before comparing |
| Size chart looks complete | Chart may belong to another style or generic store template | Confirm the chart label and selected product are connected |
| Redirect succeeds | URL conversion worked, but identity has not been checked | Repeat the five-point match test on the final page |
What a link converter can and cannot do
A converter or link extractor can help reveal or translate a source URL. That is useful when an agent wrapper hides the original marketplace page or when you need to compare the same source through another interface.
It cannot verify seller reliability, product quality, availability, measurements, compatibility, payment safety, or whether the spreadsheet note is current. Treat “converted successfully” as a navigation result only.
Know when to stop tracing
Stop when the trail becomes less specific instead of more specific. A broken product page that leads only to a store homepage, an album with no matching code, or repeated redirects without a stable item is not a puzzle you must solve.
- Remove the row if the current product cannot be identified.
- Keep it as “maybe” only when one clearly named check could resolve the uncertainty.
- Do not enter account, payment, identity, address, or order information on an unfamiliar page just to continue the trace.
- Use the official service connected with a transaction for login, payment, tracking, refund, or support questions.
Save a source-check note
Row cue: __ · final page type: __ · exact option matched: yes / no · price and option checked: yes / no · mismatch: __ · checked on: __.
Pair this note with the QC photo review. When the destination matches and the photos are clear, use the checklist to decide whether the row stays.
