Google Shopping Feed Optimization Checklist

Your product feed tells Google what you sell, what each item costs and whether it is available. Accurate data helps products remain eligible and gives Google's matching systems better information. It does not guarantee a particular click-through rate or ROAS.

Use this checklist alongside Google's current product data specification. Requirements change, and some attributes depend on product category and target country.

Start with eligibility and accuracy

Before rewriting titles, check the fields that can stop a product from serving:

• The product ID is stable and unique.
• The landing page works on desktop and mobile.
• Price and currency match the landing page and checkout.
• Availability matches the landing page, checkout and structured data.
• The primary image is accessible to Google and represents the product accurately.
• Shipping, tax and return information meets the rules for the target country.
• Required identifiers and category-specific attributes are present.

Merchant Center's "Needs attention" view should be the first stop. Fix disapprovals and broken data before judging a title or image test.

Write titles for identification, not keyword volume

Google allows up to 150 characters for the standard title attribute, but titles can be shortened in different placements. Put the details that help a shopper identify the item near the beginning.

A useful starting pattern is:

[Brand] [Product type] [Distinguishing attribute] [Variant]

For example, a title might state the brand, product type, material, colour and size. The order should reflect what matters in that category. A model number may matter more than colour for electronics, while size and gender may matter more for apparel.

Review each title for these points:

• It matches the product on the landing page.
• It describes one product rather than a list of variants.
• Relevant variant details such as size or colour are included.
• Promotional language, shipping offers and repeated keywords are removed.
• Capitalization and punctuation are readable.
• The most useful identifying terms appear early.

Submit each variant as its own item when Google's specification requires it, and connect variants with the same item_group_id. Keep the product ID stable when the item is updated.

Keep descriptions accurate and specific

The description field can contain up to 5,000 characters. Length alone is not the goal. Use enough detail to identify the product and answer the questions that matter before a click.

Include relevant facts such as:

• Material, dimensions or technical specifications.
• Intended use and compatible products.
• Care instructions or package contents.
• Variant information that matches the submitted item.

Do not add claims that the landing page cannot support. Remove store links, competitor comparisons, unrelated accessories and promotional text. If generative AI produced the description, follow Google's current rules for the structured_description attribute.

Check product identifiers

Identifiers help Google understand which product is being sold. Use the manufacturer's values rather than inventing or reusing them.

• Submit a valid GTIN when the manufacturer has assigned one.
• Submit the brand exactly as it appears on the product or packaging.
• Use MPN where applicable.
• Use identifier_exists only according to Google's specification. It is not a workaround for a missing identifier.

Incorrect identifiers can be more damaging than a blank optional field because they connect the item to the wrong product.

Review every primary image

The primary image should show the submitted product clearly and comply with the current image_link requirements.

Check that:

• The URL works and Google can crawl it.
• The image shows the whole product accurately.
• Text overlays, watermarks and promotional elements are absent.
• The product is large enough to inspect without being cropped.
• The image is sharp and uses a suitable background.
• Additional images add useful views rather than duplicates.

Lifestyle images are not universally prohibited. Google accepts them in some contexts when the product remains clear, and it provides a separate lifestyle_image_link attribute. Use the current category guidance instead of applying one background rule to every product.

Google has announced a minimum of 500 by 500 pixels for all product images, with enforcement beginning 31 January 2027. Check the official image page before a large image project because dates and requirements may change.

Add attributes that help identify or group the product

Optional in one category can be required in another. Review the specification for each target market.

Common fields to check include:

• color, size, material, pattern, gender and age_group for relevant apparel and variant products.
• google_product_category and the retailer's own product_type.
• condition for used or refurbished items.
• item_group_id for variants.
• Custom labels for campaign grouping, margin tiers, seasonality or other internal reporting needs.

Custom labels help you organise campaigns and reports. They do not replace customer-facing product attributes.

Keep price and availability in sync

Google requires submitted price and availability to agree with the product page. Price must also match checkout in the target currency.

Review:

• Base price and active sale price.
• Sale effective dates where used.
• Currency and tax treatment for the target country.
• in_stock, out_of_stock, preorder or backorder values.
• availability_date when required for preorder or backorder items.
• Structured data on the landing page.

Stores with frequent price or stock changes should use a feed, API or platform integration that updates often enough to keep those surfaces aligned. Monitor the result rather than assuming a connector is current.

Investigate disapprovals by cause

Issue	What to compare	Typical action
Price mismatch	Feed, page markup, visible page price and checkout	Correct the source that is stale
Availability mismatch	Feed, page and checkout status	Update the feed or site data
Image problem	URL access, content and current image requirements	Replace or re-host the image
Invalid landing page	Status code, redirects and mobile rendering	Repair the final product URL
Missing shipping data	Merchant Center settings and target-country rules	Add the required service and cost data
Identifier problem	GTIN, brand, MPN and identifier_exists	Submit the manufacturer's correct values
Policy issue	Product, claims and destination page	Read the cited policy and correct the underlying issue

Do not assume that one checklist catches a fixed percentage of disapprovals. Merchant Center names the affected items and policy, so work from that evidence.

Localize feeds for each target country

A feed used across markets still has to match the language, price, tax, shipping and legal information shown to shoppers in each country.

Check:

• Product text is written for the target language.
• Currency and tax treatment match the destination page and checkout.
• Shipping cost and delivery time are accurate for that country.
• Availability reflects inventory that can actually serve the market.
• Category and regulatory attributes follow the local specification.

A localized feed cannot fix a landing page or checkout that remains inconsistent with the market.

Use a review cadence that matches the catalogue

Set the review schedule from catalogue size, stock volatility and update frequency. A small catalogue with stable stock needs a different process from a large catalogue with frequent price changes.

A sensible starting cadence is:

Timing	Review
Automated or daily	Price, availability, source processing and new disapprovals
Weekly	High-spend products, rejected items and material data changes
Monthly	Search terms, product-level clicks, conversions, margin and feed completeness
Before a new market or season	Language, shipping, tax, promotions and category requirements

Adjust the schedule when Merchant Center warnings, stock volatility or campaign spend make a faster review worthwhile.

Measure feed changes without inventing a lift

Record the products and fields changed, then compare a suitable period before and after. Watch approval status, visibility, search-term relevance, clicks, conversion rate and contribution margin.

Traffic mix, bids, promotions and seasonality can move at the same time. Where volume allows, test a defined group of products rather than rewriting the whole feed and attributing every change in performance to the feed.
