Why this matters
Blocking crawling of faceted URLs with low value prevents overuse of crawl budget and indexing of thin or duplicate content, improving discovery of important pages.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Identify URL patterns representing low-value or infinite facet combinations.
- Add Disallow rules in robots.txt using wildcards matching these URL parameters or paths.
- Test robots.txt rules using Google Search Console's robots tester tool.
- Monitor crawl stats and index counts for improvement.
- Refine blocking rules as site navigation evolves.
Watch for
Robots.txt disallow does not guarantee non-indexing if URLs have backlinks; improper patterns can lead to inconsistent blocking.
Definition of done
Search engine crawlers are prevented from accessing low-value faceted URLs, reducing crawl errors and index bloat.
