Faceted Navigation Auditor
Free, no signup. Paste category parameter URLs to classify filters, actions, sort, pagination, tracking, and unknown keys. The audit stays in your browser and never crawls beyond the supplied list.
No evidence bundle loaded.
Add interaction and accessibility-tree evidence
Runs entirely in your browser — nothing you paste is uploaded or stored. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.
Sample report Built-in deterministic example
…/shoes?color=blue&size=10: filter, filter
…/shoes?compare=123: action
…/shoes?sort=price&page=2: sort, pagination
…/shoes?utm_source=newsletter: tracking
Advice: Remove crawlable action URLs where possible, then review filter combinations separately.
How to use it
- Paste up to 150 absolute HTTP(S) category URLs, one per line.
- Select Audit facets, or load the built-in deterministic example.
- Review each parameter type and any over-parameterized row.
- Use server logs, crawl data, index coverage, and search demand before deciding which combinations should be indexable.

What the results mean
- filter — common product/category attributes such as color, size, brand, price, or category.
- action — add-to-cart, remove, compare, wishlist, quantity, or buy controls that should be reviewed for crawlable links.
- sort — sort, order, or view controls.
- pagination — page, p, or offset keys.
- tracking — common campaign/click identifiers.
- unknown — no rule matched; inspect its purpose manually.
- trap — a row has more than five parameters, or the supplied list crosses the shared calendar/high-cardinality pattern thresholds.
How it works
The browser parses each supplied URL with the native URL API, classifies every query-key name through explicit regular-expression rules, and applies row-level and grouped-pattern warnings. Calendar groups over 60 unique URLs and other groups over 100 are labeled with the same deterministic caps used by the crawl frontier. If any row includes a recognized filter, it returns the canonical/noindex review reminder. No requests leave the browser.
Features
- Up to 150 supplied URLs.
- Six transparent parameter classes, including common ecommerce filters and action controls.
- Optional no-new-crawl evidence join from a shared audit bundle.
- Safe DOM output for user-supplied URLs.
- Built-in example and actionable validation errors.
- Entirely client-side processing.
Limitations
Parameter names do not reveal content value or indexability. The tool does not crawl links, test robots/canonicals/noindex, read logs, or observe Google. Pattern counts apply only to the pasted list; the row warning and grouped thresholds can flag legitimate URLs or miss traps outside the sample.
Frequently asked questions
What is faceted navigation?
Faceted navigation lets users filter or sort a listing by attributes such as color, size, brand, or price. Each combination can create a distinct parameter URL.
What parameters does the auditor recognize?
It recognizes common filter names, action parameters such as add-to-cart, compare, and wishlist, sort/order/view, page/p/offset, and tracking parameters such as utm_, gclid, and fbclid. Everything else is labeled unknown.
Does every filter URL need noindex or a canonical?
No. Some combinations deserve crawlable landing pages, while others should be consolidated or blocked from crawling. Decide from demand, uniqueness, internal links, and crawl behavior rather than applying one rule universally.
Does this tool crawl my navigation?
No. It audits only the absolute URLs you paste, up to 150 rows. It cannot discover combinations, measure crawl volume, or confirm directives.
What triggers the trap warning?
A supplied URL with more than five query parameters is labeled Too many parameters. That is a simple row-level warning, not proof of an active crawl trap.

Informazioni sullo strumento
Esamina la navigazione a faccette per trovare combinazioni indicizzabili, duplicati, canonical, noindex e percorsi che sprecano crawl.
Funzionalità
- Analisi di parametri, link di faccetta e segnali canonical.
- Raggruppamento di combinazioni equivalenti o potenzialmente duplicate.
- Finding su crawl budget, indicizzazione e collegamenti interni.
- Report locale con esempi di URL e limiti dichiarati.
Come funziona
Incolla URL o HTML della navigazione, configura i parametri e avvia l’audit. Rivedi combinazioni, segnali e priorità prima di cambiare route o regole.
Limitazioni
- Il checker analizza gli URL e l’HTML forniti, non il comportamento completo dei crawler o del server.
- Un finding è un invito alla revisione: intenzione, catalogo e policy determinano la soluzione appropriata.
Domande frequenti
Ogni parametro deve essere bloccato?
No. Valuta valore per utenti e ricerca, canonical, contenuto unico e policy prima di decidere.
Il report modifica il robots.txt?
No. Mostra osservazioni e proposte; ogni modifica al server o alle route resta una decisione separata.
Un URL duplicato è sempre dannoso?
Dipende da contenuto, canonical e discovery; il finding chiede di verificare sovrapposizione e intento.
