| Brand-word or page-trace shortcut | Users who only want a rough first glance | Footers, brand words, DNS traces, and template fingerprints | This most easily merges the platform brand, frontage layer, and raw provider into one answer | Low | Use only as a first-pass screen |
| Teachable Hosting platform attribution | Users who need to judge whether the site, page, or content entry looks more like Teachable Hosting | course-site traces, student login, DNS or CNAME patterns, and platformized content-delivery behavior | It answers the platform direction, but it still cannot replace raw-network and seller-boundary judgment | Low-medium | Best as the main decision layer |
| Platform model plus raw-layer cross-check | Users who need to separate the platform model from final responsibility | Separate the online course platform entry point, content-delivery layer, and whether the real business backend or standalone site exists elsewhere; The Teachable Hosting platform layer does not automatically equal the raw provider, nor does it settle final seller, content-delivery, or standalone-origin boundaries | It needs more context and often ends in high confidence rather than absolute proof | Medium | Best as the final judgment path |
