Solutions
What the platform is used for, by industry and by problem. The machinery is identical across all of them — only the list of sources changes.
All three run on the same machinery. Only the targets differ, which is why the second one is far quicker to stand up than the first.
Brand protection
Who is selling your product, in which country, at what price. Sellers are matched against your authorised-seller list, and those not on it are followed through owner, action and re-check. Whether a listing is counterfeit or unauthorised is decided by a person.
Commerce and retail
The gap between your own price and each market's selling price, tax aligned; what moved since yesterday; and when a listing disappeared. Nobody publishes it, so it has to be measured.
Evidence and compliance
What a page showed, in which country, on which date — kept so that it can be checked later.
Where to start
Start with what already hurts. None of these needs the others. Once one list of sources exists, the next is configuration rather than construction.
If you are undecided, read the measured case study — it records what was measured and how each comparison was made.
How to choose a tool sets out how to choose, use by use. What daily reading tells you is under what it can do.
