Measure the catalog
Find missing identifiers, weak product data, structured-data gaps, price and availability problems at SKU level.
Measure → Explain → Fix → Remeasure. Lumen shows which product data is weak, which competing domains appear in measured shopping searches, what changed between measurements, and the SKU-level fixes your team should implement next.
Find missing identifiers, weak product data, structured-data gaps, price and availability problems at SKU level.
Identify competing domains and sources appearing in the shopping searches Lumen actually measured.
Turn findings into prioritized product-level actions instead of another generic visibility score.
Compare before and after measurements for SKU issues, visibility and observed source changes.
Monitor SKU, visibility and source changes monthly or weekly according to your active plan.
Start with evidence. Scale catalog coverage and measurement cadence as you grow.
Explore Lumen with a 3-product preview.
One-time analysis for up to 1,000 products.
Ongoing measurement for up to 1,000 products.
For growing catalogs up to 5,000 products.
For established catalogs up to 25,000 products.
Configurable measurement for 25,000+ products.
Lumen establishes a baseline, documents the evidence, prioritizes fixes, and gives your team a path to remeasure the same signals after implementation.
Check my store free →Enter your store URL. We inspect the public catalog and product pages.
Compare public product details with OpenAI's published feed fields, then review six product-intent searches and their returned sources.
Receive evidence, catalog gaps, priorities, methodology and recommended fixes.
Implement the changes, then repeat the measurement to document what changed instead of relying on assumptions.
We check three public product pages for missing details that can make products harder to understand and find. The free scan does not include the six paid shopping-related searches.
This walkthrough shows how Lumen reviews a catalog, checks shopping-related searches, and turns findings into a prioritized fix list.
Lumen checks product details, pricing, availability, structured data and page content.

Exactly where product and catalog work should begin.
Lumen establishes a baseline, turns catalog gaps into SKU-level fixes, then remeasures the same storefront so your team can see whether the work actually changed the measurable signals.
Track ACP / ChatGPT commerce field coverage before and after fixes: product ID, title, description, URL, brand, seller, image, price and availability.
Measured as field coverage · 0–100See how many detected product issues remain, which high-priority gaps were reduced, and where regressions appeared after implementation.
Measured at SKU levelRepeat the measured shopping-query set and compare whether your storefront and competing source domains appear differently over time.
Provider and method always disclosedMove from diagnosis to an ordered implementation list instead of a generic SEO checklist. Remeasure after shipping the changes.
Fix → remeasure → proveThe value is not the audit alone. It is knowing what to change and having a measurement you can repeat afterward.
Yes. A completed assessment establishes the baseline. Later measurements compare recorded product issues, high-priority gaps, feed-field completeness and measured search evidence. Lumen reports the observed change; it does not invent attribution when the evidence cannot prove causality.
One storefront assessment covering up to 1,000 discovered SKUs/products, ACP / ChatGPT commerce feed-field readiness, Google Product/Offer checks, six Tavily shopping-related searches, competitor/source evidence, SKU-level priorities and a client-ready PDF fix plan.
No. No outside service controls third-party recommendations. Lumen improves measurable product-data readiness and records disclosed search evidence. Direct assistant measurements are only labeled as such when a legitimate provider integration exists.
An isolated audit tells you where you started. Monitoring remeasures the storefront, preserves change history and makes regressions visible, so you can see whether implemented work is moving the tracked signals.
If the completed $299 assessment contains no actionable, verifiable finding, you may request a refund of the assessment fee. This promise does not guarantee rankings, traffic, recommendations or sales.
The $299 one-time assessment covers one storefront. Lumen checks up to 1,000 discovered SKUs/products against OpenAI's published shopping-feed fields, reviews Google Product/Offer data, and runs six product-intent searches with Tavily Search. You receive the product sample, field-by-field coverage, pages and sources returned, competitor examples, and a prioritized, client-ready PDF fix plan. OpenAI feed access is currently limited to approved partners; this assessment prepares and reviews your public product data without promising approval, placement, or sales results.
