About this tool
Inspect supplied filter-URL evidence before release while keeping crawl prevention, noindex, and canonical signals distinct.
Faceted Navigation Indexability Checker statically compares supplied filter URLs with declared canonical, robots, evaluated crawl, HTTP status, and result-count evidence. It classifies parameter keys and surfaces policy conflicts without fetching a page or determining Google's selected canonical or index state.
- Accepts pipe- or tab-separated URL, canonical, robots, evaluated crawl state, HTTP status, and result-count rows.
- Separates potentially valuable, unnecessary, tracking, unknown, repeated, and inconsistently ordered parameter evidence.
- Reviews prevent-crawl and potentially indexable policy conflicts without treating canonical, noindex, and robots.txt disallow as equivalent signals.
- Checks supplied zero-result evidence for the 404 behavior recommended by Google's current faceted navigation guidance.
How to use Faceted SEO Checker
Enter an absolute base URL, choose a prevent-crawl, potentially indexable, or observation strategy, and classify valuable and unnecessary parameter keys. Paste pipe- or tab-separated URL, canonical, robots, crawl, status, and result-count rows, then run an explicit inspection and review the bounded row evidence or JSON report.
When this tool is useful
- Audit category and search filter URLs before launching new faceted navigation templates.
- Review normalized crawler and deployment evidence when filtered pages start appearing in search unexpectedly.
- Compare parameter policy, canonical hints, noindex, evaluated crawl state, and empty-result status evidence without treating them as interchangeable.
Practical tips
- Define which parameters are valuable to searchers and which only create unnecessary combinations before choosing a crawl policy.
- Do not combine noindex with robots.txt disallow when Google needs to observe the noindex directive.
- Verify the supplied evidence with deployed crawls, response headers, rendered canonical tags, and internal discovery paths.
Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Review unnecessary filter combinations
Example input
Facet URL, clean canonical, noindex, evaluated crawl state, status, and result count
Expected output
Prevent-crawl gaps and blocked-noindex conflicts
robots.txt crawl prevention and noindex have different behavior and should not be treated as interchangeable.
Review potentially valuable facets
Example input
Brand and material URL variants with self canonical and allowed crawl evidence
Expected output
Policy conflicts, canonical shape, parameter order, and zero-result status evidence
The report checks the supplied contract while leaving live canonical selection and indexing unproven.
Validation checklist
- Classify valuable, unnecessary, tracking, and unknown parameter keys before interpreting rows.
- Keep crawl prevention, noindex, and canonical consolidation evidence conceptually separate.
- Verify robots rules, HTTP responses, rendered directives, internal links, result counts, and Search Console state with live evidence.
