No canonical tag
Why it matters
Without a canonical, parameter and variant URLs compete with each other.
What to do about it
Add a self-referencing canonical to every indexable page.
The engine generates this fix itself using the add_self_canonical strategy. It arrives in your queue as a complete artefact, because an incomplete fix never reaches the queue, and once you approve it the change is pushed and the page re-fetched to confirm it is live.
How it is weighted
These are the values the scoring actually uses, not a description of them. Priority is derived from all three rather than chosen, which is why a high-impact, low-effort finding surfaces above a severe one that would take a quarter to fix.
- Severity
- medium
- Impact
- 40% of the weight this category can carry
- Effort
- 20%, where 100% is a project rather than a change
- Confidence
- 80% that a hit is a real problem rather than a pattern we misread
- Area
