Technical eligibility, control 17 of 20
T-17 Control faceted-navigation URL spaces
P1Needs your evidence
Decide which filters deserve discovery and which create unbounded or low-value URL combinations. Canonicalisation is not an all-purpose crawl-budget solution.
- Priority
- High priority.
- Hard gate
- No
- Change class
- APPROVAL_REQUIRED: Required exact authority must be valid before the consequential action.
- Quality bucket
- Not scored
Evidence to review
- Parameter inventory, generated URL samples, server logs and indexation checks for each class.
How to implement
- Classify filters by distinct utility, inventory stability and real demand.
- Provide curated indexable landing pages only where justified.
- Normalise parameter order and repeated filters; define invalid and empty-result behaviour.
- Plan removals before applying crawl blocks to already indexed URLs.
How UltimateSEO checks this
Needs your evidence. No automated check covers this control, so it stays UNKNOWN until evidence is supplied.
