Identify the differences
Check whether the searches used the same image, account tier, category and filtering options. A logged-out preview may not expose the same source details as an entitled account.
Make the comparison useful
- Record date, service and visible settings.
- Compare identical permissioned inputs.
- Separate unavailable features from missing matches.
- Review provider documentation for regional availability.
If one account uses a limited demonstration, its empty result is not evidence that a full index has no copy. Likewise, a region-specific feature restriction is different from a poor visual match.
Respect access boundaries
Do not evade geographic or account restrictions to force a comparison. Choose a service legitimately available for your task and describe the limits of the environment you tested. A clear account of the conditions is more informative than an unexplained claim that one provider “works everywhere”.
