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.

ツールについて
カテゴリURLのパラメータを分類し、フィルター、アクション、並べ替え、ページネーション、トラッキング、不明なキーをクロールせずに監査します。
最大150件の絶対HTTP(S)カテゴリURLを貼り付け、行ごとのパラメータ種別と過剰パラメータ警告を確認します。
機能
- 最大150件のURL入力
- ECフィルターとアクションを含む6つの透明なパラメータ分類
- 追加クロールなしの監査バンドル結合
- ブラウザー内の安全なDOM出力と決定論的な例
仕組み
ブラウザーのURL APIで各URLを解析し、明示的な正規表現ルールでクエリキーを分類します。行単位とグループ単位の警告を適用し、カレンダー系60件超、その他100件超のグループには決定論的な上限を示します。認識されたフィルターがあればcanonical・noindexの確認を促します。
制限事項
- パラメータ名だけでは内容やインデックス登録可否は分かりません。リンクのクロール、robots・canonical・noindex、ログ、Googleの状態は確認しません。件数は貼り付けた一覧だけを対象にし、正当なURLを警告したり、サンプル外のトラップを見逃したりする場合があります。
よくある質問
ファセットナビゲーションとは何ですか？
色、サイズ、ブランド、価格などの属性で一覧を絞り込んだり並べ替えたりする仕組みです。組み合わせごとにパラメータURLが増えることがあります。
監査が認識するパラメータは何ですか？
一般的なフィルター、add-to-cart・compare・wishlistなどのアクション、sort・order・view、page・p・offset、utm_・gclid・fbclidなどのトラッキングを認識します。
すべてのフィルターURLにnoindexまたはcanonicalが必要ですか？
いいえ。需要、独自性、内部リンク、クロール挙動から、インデックス可能なランディングページにする組み合わせを判断してください。
