Why this matters
Blocking crawling of unnecessary filter combinations helps prevent crawl budget waste and index bloat on large ecommerce sites.
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.
- Analyze URL patterns for faceted parameters or directories.
- Add 'User-agent: * Disallow: *parameter=*' or 'Disallow: */parameter/*' rules to robots.txt.
- Test with robots.txt testing tool for correctness.
- Avoid blocking valuable sub-paths needed for indexing.
- Monitor crawl activity to confirm blocks.
Watch for
Robots.txt blocking does not guarantee deindexing; URLs with backlinks or followed internal links might remain indexed.
Definition of done
Robots.txt disallow rules exclude specified faceted URL patterns from crawl logs and Search Console crawl stats.
