Optimizing a Google Shopping feed: titles, images, GTIN

Optimizing a Google Shopping feed isn't about stuffing 10 keywords in the title. It's patient work on a dozen fields that, combined, take a ROAS from 2 to 5. This guide lists the real levers and how Seegea activates them in a few days.

A Google Shopping feed isn't a checkbox. It's a living asset you work on week after week. Merchants reaching 4+ ROAS all share the same reflex: they optimize the feed, not just bids.

Here are the 5 levers that, combined, make the difference — and how Seegea activates them without CSV roundtrips or back-office time drain.

Seegea works on your source catalog

Lever 1 — Structured, exhaustive titles

Google favors titles where brand appears first, followed by product type, key attributes (size, color, capacity) and possibly gender. 70 characters are the visible display, but the full 150 characters are used for matching.

Seegea generates these structured titles from existing attributes, in 1 click, on multi-selection. 500 titles reworked in 5 minutes instead of a week.

Lever 2 — Enriched descriptions

Description is underused. Google parses all the text to determine which queries match your listing. An 800-character description with the right business terms can double long-tail impressions.

1-click AI description

500-1000 character generation, with product attributes, benefits and long-tail search terms.

Fast human validation

Editor validates, adjusts or regenerates. Typical rhythm: 30 s per listing with review.

Bulk edit by category

Apply a description pattern to a whole category, respecting each listing's specific attributes.

Lever 3 — Compliant, attractive images

  • Resolution: 1000×1000 minimum, ideally 1600×1600
  • Background: neutral for main, lifestyle for secondary
  • Weight: WebP compression for Core Web Vitals
  • Consistency: uniform style across the category

Lever 4 — GTIN and required attributes

A missing GTIN is a strong negative signal for A9 Shopping. Same for age_group, gender, color, size in fashion. Seegea filters incomplete listings and fixes them in bulk.

Lever 5 — Precise Google categorization

google_product_category must point to the right leaf of Google's official taxonomy (not just "Apparel"). Precise categorization improves query matching and Performance Max segmentation.

The cumulative effect of these 5 levers on a 2,000-SKU catalog translates within a few weeks into +30 to +60% impressions and mechanical CPC decrease. But you need a way to execute without spending 2 months.

What makes the difference over time

A Google Shopping feed optimized once works for 2 months. A continuously optimized feed is a durable edge. The right setup: every new product created is automatically enriched to the same standards as the 500 you just optimized.

Built in France between Annecy and Chantilly, Seegea is designed for acquisition and product teams who want to industrialize that quality. We support you by email and Google Meet to calibrate patterns within the first week.

FAQ

Google Shopping recomputes impressions 24-72h after a feed update. For ROAS, expect 2 to 4 weeks for Performance Max to re-learn your optimized listings.
