How to send a strong correction report

How corrections are handled
- The report is reviewed against the formula and expected use case.
- If the issue is confirmed, the calculation logic, copy, schema, redirects, or sitemap status can be updated.
- High-risk issues affecting finance, health, construction, tax, or engineering pages receive higher priority.
- Weak pages may stay noindexed until the correction and explanation quality are strong enough.
