Google Merchant Center

Monitor competitor prices straight from your Merchant Center catalog.

Connect Google Merchant Center once and Comptrace uses your existing product feed to match comparable competitor offers and track their prices. No manual competitor URL lists, no duplicate catalog upkeep.

Catalog access is read-only. Comptrace never changes your products or prices.

Read-only access, AI matching, automatic competitor discovery

Comptrace reads your Merchant Center catalog to identify each product, then uses its identifiers (GTIN, MPN, brand, title, category, URL) to AI-match comparable competitor offers and discover competitors via Google. You skip building and maintaining competitor URL lists, and access is read-focused: Comptrace never edits, publishes, or reprices anything in your account.

  • Reuses your existing GMC feed instead of asking you to re-upload a catalog
  • Matches products automatically using GTIN, MPN, brand, title, and category
  • Discovers competitor offers via Google rather than manual URL lists
  • Read-only by design: no changes to your products, prices, or listings
  • Your catalog, competitor rows, and scraped prices stay private to your workspace

Not ready to connect? Start with one product

You do not need a Merchant Center connection to see how Comptrace works. Paste one product URL or write an exact description to check public competitor offers, then connect your catalog when recurring, catalog-wide monitoring makes sense. Already-supported public URLs preview almost instantly; new or harder products can take up to about 15 minutes, so the request is stored and followed up rather than dropped.

  • Preview results from one product URL before committing to a connection
  • Supported public URLs return matches and prices almost instantly
  • Harder products are queued for up to ~15 minutes, then followed up
  • Coverage gaps appear as exceptions with status and timestamps, never hidden
  • A public product check changes nothing in your store or Merchant Center account

Integrations

Start competitor price monitoring from Google Merchant Center, a CSV product feed, or a guided import. Comptrace matches catalogs to rivals automatically.

Price mismatch fixes

Fix Google Shopping price mismatches: see why feed and landing-page prices drift, and use scraped-at evidence to catch and resolve them fast.

Google Shopping price monitoring

Turn Google Shopping listings into traceable competitor price evidence: AI-matched offers, scraped-at timestamps, price rank, average gap, and trend.

CSV Import

Import a CSV product feed to monitor competitor prices. Map URLs, titles, prices, GTIN, MPN, and brand, validate rows, then track gaps privately.

Brand monitoring

Brand price monitoring across retailers: track who sells your products, spot price changes, and review match evidence with scraped-at timestamps.

Prices stay private

Your workspace is logically isolated. No catalog field, imported price, or scraped result ever feeds into another account.

Matching is explainable

AI uses product text, identifiers, imagery, retailer pages, and Google-discovered data to decide whether offers are comparable.

Metrics are action-oriented

Price rank, average gap, trend direction, and scraped-at timestamps tell teams what changed and whether the data is fresh.
