PDP SEO Checker

Free, no signup. Structurally check the primary Product or ProductGroup, selected offer, buy-box price, currency, availability URL and variant graph. JavaScript-only buy boxes and product feeds are not evaluated.

Built by Patrick Stox

Checks run from our server; we fetch the URL you enter and don't keep the results. 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 Deterministic detector example
HTML containing one Product, one USD Offer with price 10, https://schema.org/InStock, and a $10 price beside “Buy now” returns:
Product graph: 1 Product · 0 ProductGroup · 1 Offer. Primary entity: Product.
Primary offer: 10 USD with a valid currency code.
Availability: Valid Schema.org availability URL.
Buy-box consistency: Primary schema price matches the buy-box price.
 
 
 
How to use it
  1. Enter the canonical product detail page and select Audit.
  2. Review the Product, offer-price, availability, and consistency rows separately.
  3. Confirm a mismatch against source HTML and the selected variant before editing.
  4. Run a complete structured-data and merchant-feed validation afterward.
 
 
 
       
     
 
    
What the results mean
  • Product graph — totals for Product, ProductGroup and Offer entities, plus the structurally selected primary entity.
  • Primary offer — a positive price and recognized ISO 4217 priceCurrency on the primary product’s offer.
  • Availability — a recognized Schema.org ItemAvailability URL, not merely an availability property.
  • Buy-box consistency — the selected schema price matches a non-placeholder price found near the product purchase action.
  • Variant graph — unusually large variant sets and multiple competing top-level products are called out.
 
How it works
The protected endpoint supplies public raw HTML. The detector parses JSON-LD as JSON, walks typed entities and linked offers, ranks Product and ProductGroup candidates using page URL, graph position and offer evidence, then searches the bounded buy-box region around the purchase action. Cart totals, financing examples, placeholders and zero prices are excluded.
 
Features
  • Structural JSON-LD parsing rather than regular-expression extraction.
  • Product, ProductGroup and Offer totals.
  • Primary/selected product and offer identification.
  • Currency and Schema.org availability-URL validation.
  • Buy-box-scoped price comparison with noisy-price exclusions.
  • Variant-entity and competing-primary warnings.
 
Limitations
The primary-entity and buy-box selection are deterministic heuristics, not access to the store’s internal selected-variant state. The tool does not render JavaScript or inspect Merchant Center, feeds, reviews, shipping, returns, stock truth, or checkout behavior. Confirm warnings against the rendered selected variant before changing production markup.
 
Frequently asked questions
What does the PDP SEO Checker audit?
It structurally parses every JSON-LD block and Product schema graph, identifies the best primary Product or ProductGroup candidate, validates its selected offer, and compares that non-zero schema price with a price found inside the product buy box.
Does it validate Product rich-result eligibility?
No. It does not cover every required or recommended Product and Offer property or Google policy. Use a full schema validator after this focused consistency check.
Why is price consistency not evaluated?
The detector needs both a usable non-zero price on the primary schema offer and a recognizable price in the raw-HTML buy-box region. Cart totals, financing examples, placeholders, and $0.00 values are ignored.
Can it check JavaScript-rendered buy boxes?
No. The fetch audit reads raw HTML and may miss prices, variants, or availability inserted only after scripts run.
Does it check Merchant Center or product feeds?
No. Feed approval, shipping, returns, variants, identifiers, and Merchant Center diagnostics are separate from this page audit.

ツールについて
raw product schema、価格、在庫、表示価格の整合性を監査します。
商品ページの可視情報とProduct JSON-LDを比較し、購入可能なオファーの価格、通貨、在庫状態を確認します。
機能
  • Product JSON-LDの確認
  • 価格と通貨の検証
  • 在庫状態の整合性確認
  • 表示価格とスキーマ価格の比較
仕組み
raw HTMLとProduct JSON-LDから商品、Offer、価格、通貨、availability、表示価格を抽出し、同じ購入可能オファーを指すか比較します。欠落、不正、価格不一致、在庫不一致を証拠付きで分類します。
制限事項
  • 解析は入力または取得したHTMLに限られ、実際の購入可能性、在庫、決済、検索結果表示、売上を保証しません。
  • 価格や在庫は時間、地域、バリエーション、ログイン状態で変わる場合があり、観測時点以外を推測しません。
よくある質問
このツールは価格や在庫を更新しますか？
いいえ。観測したページと構造化データを比較するだけで、商品や在庫システムへ書き込みません。
価格が一致すれば商品スキーマは正しいですか？
保証されません。Productの識別、通貨、在庫、可視情報、ページの購入条件も合わせて確認してください。
バリエーション商品にも使えますか？
入力されたページとProduct構造化データの観測範囲で確認します。各バリエーションの価格・在庫・識別子が正しく対応しているか別途レビューしてください。
