How to verify an SEO fix without running another full crawl.

Keep the original evidence immutable

The crawl that created the task should remain available as historical evidence. Store a targeted result beside it with its own timestamp, scope, attempts, cache context, and rule version.

If a fresh check fails, the correct outcome is an inconclusive verification—not a mutation of the original finding.

Choose the correct verification role

• Re-parse source pages for links, canonicals, hreflang, and schema references
• Re-fetch targets for response, redirect, and asset outcomes
• Recompute the rule using the same stored normalization model
• Record URLs that could not be fetched instead of subtracting them from the denominator

Escalate to a full crawl when scope is global

Orphan detection, complete sitemap coverage, site-wide duplication, and some graph rules depend on a complete inventory. A targeted check should say when it cannot establish that inventory.
