Merchant Center · rehall-eu
Content API + scheduled XML
Google reads attributes,
not intentions.
Most disapprovals are boring: a missing GTIN, an image under the size minimum, promotional text stuffed in a title, a price that doesn't match the landing page. Each one silently pulls a product off the Shopping tab, and you find out days later in a dashboard nobody checks.
NEXERA generates the feed from structured data, so those mistakes can't be typed in the first place. And everything is validated against Google's rules at build time: what leaves the platform is exactly what Merchant Center wants to receive.
Your PIM fields, fluent in Google.
Every Google attribute is mapped from the model once: titles from your localized copy, GTIN from the EAN field, prices from the market price list, images from the DAM in Google's preset. Custom attributes ride along as supplemental data. No per-product busywork, ever.
48 attributes auto-mapped · overridable per store

Caught at build time.
Not in your disapproval report.
Before a feed leaves NEXERA, every item runs the same checks Google will run, plus a few Google won't tell you about. Failures block the item, not the feed, and land on a worklist with a one-click fix where possible.
GTIN checksum
Every EAN is checksum-verified and length-checked. Placeholder codes and duplicates are flagged before submission.
12,128 / 12,128 valid
Image minimums
Hero images below Google's size floor are re-rendered from the DAM master automatically. No gray placeholder, no rejection.
100% ≥ 1200 px
Title policy
Promo phrases, ALL CAPS and over-length titles are detected. Auto-fix trims to the limit at a word boundary.
3 titles auto-trimmed
Price & availability parity
Feed price and availability are read from the same model your storefront syncs from. Parity is structural, not hoped for.

6,000 categories. Zero spreadsheet lookups.
Google's product taxonomy runs six thousand categories deep, and the right one moves your CPC. NEXERA's AI reads the product record and proposes the exact google_product_category, with a confidence score. You approve per category, not per product.
AI-suggested, human-approved · confidence shown per mapping
Category mappings inherit down your own category tree
Product type passed alongside for your own reporting
Nothing reaches Google before it's ready.
Products move through an explicit lifecycle: draft, review, published, archived, with role-based gates deciding who can promote. Incomplete products simply don't go out, so a half-finished item never becomes a disapproval. Every field change is logged with the author, the timestamp, the before and the after.
Role-gated transitions: editors draft, managers publish
Field-level diffs on every save
One-click rollback to any prior state

Supplemental feeds
Extra attributes ship as supplemental feeds keyed on item id: lifestyle image links, energy labels, whatever a campaign needs.

Availability that's true
Stock reads from the same inventory your storefront uses. When a SKU sells out, the feed says so on the next delta, not next week.

Feed apps patch.
The PIM prevents.
A feed app reformats whatever your store happens to contain. NEXERA fixes the data upstream, so the feed, the storefront and every other channel agree.
