How do you prioritize technical SEO issues when there are hundreds of problems?

A practical model is:

Priority ≈ Impact × Scale × Confidence ÷ Effort

For example, a canonical problem affecting 100,000 important product URLs is materially different from a missing meta description on 100 low-value pages.

Ask:

1. Are important URLs affected?
2. Is Google actually encountering the problem?
3. Does it affect discovery, rendering, indexation or consolidation?
4. How many URLs are affected?
5. What is the business value of those URLs?
6. Can the fix introduce migration or indexing risk?

Google's technical requirements are relatively small; passing them does not guarantee crawling, indexing or ranking. This is why an audit report should not be treated as a priority list automatically.
