- DestinationThe link opens the expected product-detail environment rather than a generic homepage or search.
- IdentityThe live title and primary images describe the same product as the saved card.
- VariationThe intended size, colour and version still exist and can be selected.
- Current detailsThe live price and availability replace the snapshot values for the decision.
- EvidenceAny QC or measurement information required for the shortlist is still accessible.
Match stable features before small styling details
Compare product type, silhouette, major colour blocking, closure and obvious model features. Seller titles may be abbreviated or translated, so do not require identical wording. However, a different product type, major design change or unrelated image means the saved card can no longer support the decision.
Select the intended variation before trusting the amount
A listing can remain live while the desired size or colour disappears. Some listings display a low starting price belonging to another option. Choose the required variation, confirm stock and record the amount shown for that exact selection.
Recognise soft failures
| Result | Meaning | Action |
|---|---|---|
| 404 or unavailable message | The listing cannot currently be used | Return to the category |
| Homepage or search redirect | The original item reference was not preserved | Do not continue by assumption |
| Different product | The destination content changed | Remove it from the shortlist |
| Missing option | The listing is live but not actionable for your need | Compare an alternative |
| Matching live listing | The saved card still provides a useful route | Continue with size and evidence checks |
Keep the listing check separate from product approval
A matching live page confirms that the link still represents the intended product. It does not authenticate the item, approve the seller or guarantee the condition of a warehouse unit. Apply the QC and sizing checks after the link passes.
Replace the function, not only the image
When a link fails, return to the same category and reuse the original requirements: use, budget, measurements, construction and evidence. The closest-looking alternative is not automatically the closest practical replacement.
Browse every current categoryRecord what was checked and when
A useful maintenance note distinguishes active, changed, unavailable and mismatched links. The catalogue on this site changes only after an intentional data refresh and review; it does not silently replace products every time the server starts.
Review the published update historyGive every checked link one unambiguous state
A simple status prevents a technically live but unusable listing from remaining in the same bucket as a verified match. Record the state beside the check date and the exact reason for any failure.
| Status | Use when | Next action |
|---|---|---|
| Verified match | Product, intended option and current details agree | Continue to QC, sizing and total-cost checks |
| Changed | The product is recognisable but price, options or important details differ | Update the saved record before comparing it |
| Unavailable | The item or required variation cannot currently be selected | Keep it out of an actionable shortlist |
| Mismatched | The link opens a different item, generic page or unrelated destination | Remove or replace the route |
| Needs evidence | The listing matches but a decision-critical measurement or image is missing | Pause and request the exact missing evidence |
When several people maintain a shortlist, use the same status names and keep the previous result rather than silently overwriting it. That small audit trail shows whether a listing expired, changed options or was replaced deliberately.
A link verified during research can change later. Repeat the identity, variation and price check immediately before using it for an order decision.
Link checking FAQ
How do I know whether a LoongBuy spreadsheet link is still valid?+
Open it in a new tab and confirm that the live page loads the intended product, image, title, options and price. A page that merely loads is not enough when it redirects to a generic search or different item.
Why does a product link show a different item?+
A seller or destination catalogue may replace, remove or remap a listing after the saved snapshot. Return to the relevant category and choose another current candidate rather than relying on the old card.
Is an out-of-stock page a broken link?+
The URL may still work technically, but it is not currently actionable. Treat unavailable stock, missing required options and removed variations as reasons to pause and compare an alternative.
Should I trust the spreadsheet price when the live page is different?+
No. The live selected option is the current source for price. The spreadsheet value is a reference captured during a previous catalogue refresh.
Where can I find an alternative to an expired item?+
Return to the item's category page and compare products serving the same use. Keep the original requirements and measurements so the replacement remains like-for-like.
