Why product data matters for AI shopping

Only a few products shown

A shopper describes what they need, and the AI assistant answers with a few products. Products outside that list are not seen.

Assistants read the feed

Assistants choose from the product feed and the facts on the product page. A well-designed page does not help when the data behind it is thin.

Feeds stop at the basics

Merchant Center requires a title, price, image, and stock. To compare products, assistants also need specs, compatibility, and buyer Q&A.

Missing facts get skipped

When the feed does not answer what the shopper asked, the assistant has nothing to match. It recommends a product that has the answer.

What is Shelf Edge?

Shelf Edge enriches your product feed for Google Shopping and AI shopping answers. Complete product data matches more shopper searches and brings more clicks and sales.

  • Finds missing attributes Highlights, specs, Q&A, related products, and variant details. In an average catalog, 40-50% of attributes are empty
  • Fills them from your own pages Facts from your rendered product pages first, AI only where the pages say nothing
  • Makes the feed ready for Google Shopping Each value follows Merchant Center rules and matches the live page

How Shelf Edge works

Connect your site to EdgeComet and your Google Merchant Center feed to Shelf Edge. It fills the feed from your product pages and sends changes only after you approve them.

  1. Step 1

    Store Connected

    Connect your site to EdgeComet through your CDN, then add your Google Merchant Center feed. Your current feed and feed tool stay as they are.

  2. Step 2

    Facts Extracted

    EdgeComet renders your product pages, and Shelf Edge takes the facts already there: specs, highlights, Q&A, reviews, and related products. AI fills only what the pages do not cover.

  3. Step 3

    Values Checked

    Each value is checked against the live page before it goes out. Price, stock, and title must match.

  4. Step 4

    Updates Approved

    You review and approve the updates, and Shelf Edge sends them to Google as a supplemental feed. ChatGPT delivery Coming soon

  5. Step 5

    Results Measured

    Clicks per product come from your own Merchant Center data, with filled products compared against untouched ones.

Which product attributes does Shelf Edge fill?

Google and ChatGPT read different product attributes. Shelf Edge sends each destination only the attributes it uses.

Shelf Edge features

Fill product attributes from your own pages, check them against the live page,
approve each change, and measure the results per product.

Fill

Product attributes from your own pages

Fill missing product attributes with facts from your rendered product pages. Let AI write only what the pages do not say, with the source shown on each value.

  • Use page data first Specs, highlights, Q&A, reviews, and related products from your product pages
  • See the source of each value Each value is tagged "From your page" or "AI-written" and marked as created or improved
  • Follow Google's content rules No promotional text, no prices or shipping in highlights, no repeated facts
  • Set your brand voice Describe the tone and the words to use or avoid in plain language
Impact: complete product facts across the catalog, without writing them by hand.

Check

Feed checks against the live page

Shelf Edge reads your live product pages and catches a wrong value in the feed before it reaches Google. The checks run before each push.

  • Price check The price on the page matches the price in the feed
  • Stock check Stock on the page matches the availability in the feed
  • Missing price check Each product in the feed shows a price on its page
  • Markup check The page and its product markup agree on price and stock
Impact: products with a price or stock mismatch are held back instead of being sent to Google.
Feed checked against the live page before sending to Google: price, stock and markup checks pass, one product is held back for a price mismatch, then fixed
Approve

Approval, rules, and rollback

Review each change before it goes out. Start with one category, check the results, then add more.

  • Set rules per field Always fill, fill only when empty, never fill, or use a fixed value
  • Limit by category or price range Start with one category, then expand to the rest of the catalog
  • Roll back any setting Draft, live, and earlier versions, restored in one click
  • Check the delivery log What was sent, when, and what Google accepted
Impact: you decide what goes live, and any change can be undone.

Measure

Per-product results from your own data

Measure the results per product in your own Merchant Center data. Compare filled products with untouched ones to see what changed.

  • Track clicks per product From Google Merchant Center, before and after filling
  • Compare filled and untouched products See the difference between the products Shelf Edge filled and the ones it did not
  • Follow AI referral traffic Visits from AI assistants to your product pages, with ChatGPT data once ChatGPT delivery is live Coming soon
  • See crawler fetches Which product pages Google and AI crawlers fetch, from EdgeComet data
Impact: a per-product answer to whether filling worked, in your own numbers.

All your questions answered

No. Shelf Edge adds a supplemental feed in Merchant Center. Your main feed and your feed tool stay as they are.

Not on Google. Google ignores AI-written titles when your own title exists. Shelf Edge leaves your titles alone.

No. A supplemental feed only adds facts to products that are already in your feed.

Yes, within Google's rules. Shelf Edge follows them: no promotional text, no prices or shipping in highlights, no repeats. Facts from your pages always come first.

Two connections. Your site connects to EdgeComet, which renders your product pages for Shelf Edge. Only bot requests go through EdgeComet, and your visitors load your site as before. Your Merchant Center account connects with the one permission level Google offers, read and write. Shelf Edge writes only to its own supplemental feed, and only after you approve the changes.

Fix it or remove it, or roll back to an earlier version in one click.

Any store with a Google Merchant Center feed and a site EdgeComet can connect to: through Cloudflare, Fastly, AWS, Nginx, or a custom setup. The store platform itself does not matter.

No code changes are needed. On Cloudflare, you connect EdgeComet from your Cloudflare account in about a minute. On Fastly, AWS, or Nginx, it is a routing change, and our team sets it up with whoever manages your CDN. Then you add your Merchant Center feed.

Look at clicks per product in your own Merchant Center data. Shelf Edge compares the products it filled with the ones it left untouched. You see the difference in your own numbers.
