Overview

A large enterprise site recovered indexation of important pages by eliminating crawl waste and resolving systemic technical blockers.

Business context

An enterprise technology company running a sprawling site of tens of thousands of URLs across products, support and resources. A significant share of commercially important pages were not being indexed, while crawlers spent budget on low-value parameter and faceted URLs.

Starting metrics

Share of important pages indexed
well below where it should be
Crawl budget spent on low-value URLs
high, dominated by parameters and facets
Discovered-but-not-indexed pages
a large and growing bucket
Internal link depth to key pages
too deep for reliable discovery

Problems identified

  • Pages not indexed pattern affecting a meaningful share of revenue-relevant URLs.
  • Crawl budget waste pattern as bots repeatedly fetched low-value parameterised URLs.
  • Redirect issues and chains adding friction to crawling and consolidation.
  • Orphan pages that received little or no internal linking and were rarely discovered.

Actions taken

  1. 1
    Ran a technical audit and log analysis

    Combined the Technical Audit and Log File Analysis frameworks to see where crawlers actually spent time versus where value lay.

  2. 2
    Contained low-value URL sprawl

    Applied crawl controls and canonicalisation to parameter and faceted URLs so budget flowed to important pages.

  3. 3
    Resolved indexability blockers

    Fixed the directives, redirects and templates that were keeping important pages out of the index.

  4. 4
    Reduced click depth to key pages

    Reworked internal linking so priority pages sat closer to the surface and orphan pages were connected.

  5. 5
    Monitored recovery

    Tracked indexation and crawl distribution over the engagement to confirm budget was reallocated to value.

Results

Share of important pages indexed
moved substantially closer to full coverage (illustrative)
Crawl budget on low-value URLs
materially reduced through controls and canonicalisation
Discovered-but-not-indexed bucket
shrank as blockers were resolved
Discovery of priority pages
improved as click depth fell

Timeline: roughly 4 months

Lessons learned

  • On large sites, indexation problems are usually crawl-budget problems in disguise.
  • Log files reveal what audits alone cannot: where crawlers genuinely spend their time.
  • Reducing click depth to priority pages does as much for discovery as any directive fix.
