Enterprise tool for website platform migrations. Scan before, scan after, compare differences.
Problem: When migrating to a new platform, SEO elements break silently (titles, meta, canonicals, URLs).
Solution:
- Scan old site → baseline
- Scan new site → post-migration
- Compare → see exactly what changed
| Field | Severity |
|---|---|
| Missing URLs (404) | Critical |
| New noindex | Critical |
| Status code changes | High |
| Title changes | High |
| Canonical changes | High |
| Hreflang changes | High |
| Redirect changes | High |
| Meta description | Medium |
| H1 changes | Medium |
| OG tags | Medium |
| Image alt text | Low-Medium |
