Google Ads Shopping Feed

Currency & scope note (last reviewed 2026-07-19): Platform mechanics referenced here (character limits, campaign-type names, feature availability, thresholds, benchmark figures, policy specifics) reflect general practice as of the review date above and are not guaranteed current — ad platforms change quickly. Verify anything mechanical against the platform's live documentation before relying on it for a real launch, real spend, or a compliance-sensitive decision. This is an independent, unofficial resource, not affiliated with or endorsed by any platform named in it, and nothing here is legal, tax, or financial advice.

Purpose

Get a Merchant Center product feed structured, populated, and optimized so Shopping and Performance Max campaigns have accurate, competitive, policy-compliant product data to serve against.

Trigger Conditions

• "Optimize my product feed for Shopping/PMax"
• "My Shopping ads aren't showing for [product]"
• "Merchant Center disapprovals / feed errors"
• "Improve my product titles/images for Shopping"

Required Inputs

• Merchant Center account access status and feed source (native ecommerce platform integration, scheduled fetch, or manual upload)
• Product catalog size and category
• Current feed health status (disapprovals, warnings, if known)
• Whether promotions/sales pricing need to be reflected dynamically

Core Capabilities

Feed Structure & Attributes

• Required attributes (id, title, description, link, image, price, availability, GTIN/MPN/brand) and category-specific required attributes (e.g., apparel needs size/color/gender)
• GTIN requirement nuance — most products need one; flag when a product legitimately qualifies for an exemption
• Product category (Google product taxonomy) accuracy — miscategorization suppresses Shopping eligibility and PMax asset group matching

Title & Description Optimization

• Front-load titles with the terms buyers actually search (brand + product type + key attributes) rather than internal SKU naming
• Category-specific title formulas (apparel: brand + gender + product type + attribute + size/color; electronics: brand + model + key spec)
• Descriptions should expand on attributes/use case, not duplicate the title verbatim

Feed Health & Diagnostics

• Reading Merchant Center diagnostics: disapprovals (policy) vs. warnings (missing/weak data) vs. demoted items
• Common disapproval causes: missing GTIN, price/availability mismatch with landing page, prohibited content, image policy violations (watermarks, placeholder images, text overlay)
• Price/availability accuracy — mismatches between feed and landing page are both a policy risk and a user-trust/conversion killer

Feed Rules & Supplemental Feeds

• Feed rules for transforming/enriching data at scale (e.g., appending brand to title, normalizing GTIN format) without editing the source feed
• Supplemental feeds for adding data the primary feed lacks (custom labels for segmentation, promotional overlays)
• Custom labels for grouping products by margin, season, bestseller status — used later for bid/campaign segmentation in google-ads-campaign-builder/google-ads-optimization

Feed-Driven Segmentation

• Custom labels enabling priority-based campaign structuring (bestsellers vs. long-tail, high-margin vs. low-margin)
• This segmentation is what makes Shopping/PMax bid strategy meaningfully controllable rather than one flat pool of products

Workflow

1. Confirm feed source and current health status (pull Merchant Center diagnostics if available).
2. Fix disapprovals/critical errors first — these fully block impressions for affected products.
3. Audit and rewrite titles/descriptions for the highest-value or worst-performing products first, not the whole catalog uniformly.
4. Verify price/availability accuracy against live landing pages.
5. Set up custom labels for segmentation if the account will need tiered bidding by product priority.
6. Recommend feed rules/supplemental feeds for any systematic data gaps rather than manual one-off fixes.
7. Hand off segmented feed structure to google-ads-campaign-builder for Shopping/PMax campaign structuring.

Outputs

• Feed health summary (disapprovals/warnings, root causes)
• Optimized title/description formulas by product category
• Custom label segmentation scheme recommendation
• Feed rule recommendations for systematic fixes

Rules

• Always fix disapprovals before optimization work — a disapproved product gets zero impressions regardless of how good its title is.

• Never let feed price/availability drift from the live landing page; this is both a policy violation risk and a direct trust/conversion problem.

• Don't rewrite an entire large catalog's titles uniformly without prioritizing by revenue/impression share first.

• Verification gate: before this skill's output is used to spend real money, submit a compliance-sensitive claim, or go to a client as final, verify the mechanical specifics (limits, thresholds, policy rules) against current platform documentation and get explicit human sign-off — do not treat this skill's output as launch-ready without that check.
