Capture each URL before comparing it. Then check product identity, selected variation, commercial context and link ownership or destination.
Assign one status: aligned, unresolved, mismatched or unavailable. Record the reason and date rather than using a vague green check.
Map the chain before judging it
| Page | What it may add | What it does not prove |
|---|---|---|
| Album | Photos, captions, codes and contact clues | Current price, stock or checkout |
| Catalog result | Discovery context and possible source links | That every linked variation is identical |
| Marketplace source | Options, price basis and seller listing details | That an album uploader owns the listing |
| Reformatted or agent-ready link | A convenient route into another service | That the original URL and selected option were preserved |
Capture the chain before comparing it
Save the direct URL, visible page title, selected option, product code, destination domain and observation date for every step. If a link redirects, keep both the starting and final address. Screenshots can preserve context, but the direct URLs remain the primary record.
Run four match checks
- Identity: category, product code, visible design and key construction details agree.
- Variation: color, size, model and bundle describe the same option rather than only the same family.
- Commercial context: price basis, quantity, minimum order and included parts are not silently different.
- Destination: the final domain, seller identity and link role are recorded, especially after redirects.
Assign one status
Treat redirects and reformatted links as new evidence
A redirect can be routine, but it changes the chain. Check the final domain, page title, selected variant and whether query parameters were lost. Never describe a reformatted link as the original source unless the destination visibly preserves that source.
Handle a chain that splits into several possible sources
Some album or catalog pages lead to more than one marketplace result. Do not force them into a single straight chain. Give each branch its own row, preserve the starting page and compare identity, variation and commercial context independently. A branch with the same promotional photos but a different code remains a separate candidate.
Use the strongest independent clue first. An exact code that appears in the caption and source title is more useful than a similar thumbnail. A selected color or bundle is more useful than a broad product-family name. A price alone is a weak identity clue because unrelated options can share a number.
When one branch fails, do not silently replace its URL with the surviving branch. Mark the failed path unavailable and record why the other branch was retained. That history prevents a future reader from believing the remaining page was always the original source.
Finish the branch review with one sentence for each route: what aligned, what conflicted and which missing field matters. If two branches remain equally plausible, keep both unresolved; choosing one without a decisive clue would only hide uncertainty.
Worked example: similar photos, different option
An album and source listing share a code and show the same shoe model. The album caption says “grey,” while the source page defaults to white and includes several colors. The chain is unresolved until the intended color is selected or confirmed; it is not aligned merely because the model photos are similar.
