Crawl Architecture & Canonical Consolidation
Remediating faceted crawl traps, duplicate indexation, and crawl budget dilution across a multi-location commercial service portal.
EXECUTIVE SUMMARY
Website A operated an extensive multi-location directory where dynamic faceted filters generated over 14,000 indexable parameter permutations. Search engine bots were spending more than 40% of crawl activity on duplicate combinations rather than high-value local service hubs. By establishing strict canonical rules, refining robots crawl directives, and restructuring XML sitemaps, redundant URL indexation was eliminated while search visibility for primary regional landing pages strengthened.

Five-Dimension Honest Analysis
To ensure strict intellectual honesty, every case study separates what was directly observed, what was executed, what can reasonably be attributed, and what remains an unverified external factor.
