Google Shopping Feed Optimization: The Complete 2026 Checklist

Product titles: the single highest-impact field

Google reads your product title to decide which searches your product matches. It is the most important field in your feed, and most shops underuse it.

• Front-load the most important terms. Google weights the start of the title most heavily. Put brand and product type first, not last.
• Follow a structure that fits your category. For apparel, a reliable pattern is Brand + Product Type + Attributes (gender, colour, size, material). For electronics, Brand + Model + Key Spec. Match the structure to how people actually search in your category.
• Include the terms shoppers type. If people search "waterproof hiking boots", the words "waterproof" and "hiking" should be in the title, not buried in the description.
• Use the full character length where it helps. Titles can run to 150 characters. You do not need to fill it, but do not leave high-value terms out to keep it short.
• Do not keyword-stuff. A title that reads like a list of search terms hurts both relevance and click-through. Make it readable and informative.

If you only optimise one thing in your feed, optimise titles.

Product images: the thing shoppers actually click

Shopping is a visual format. Your image is what wins or loses the click before anyone reads a word.

• Use a clean main image on a white or neutral background for the primary product shot, in line with Google's image requirements.
• Aim for high resolution. Google increasingly favours larger, sharper images, and 500 by 500 pixels is a sensible minimum for most products, with higher resolution preferred.
• Avoid promotional overlays on the main image. Watermarks, "sale" badges and logos on the primary image can get listings disapproved.
• Add supplemental images so shoppers can see the product from multiple angles where the format supports it.

Required and recommended attributes

Google uses structured attributes to match, filter and rank your products. Missing attributes mean missed impressions.

• GTIN, brand and MPN. For products that have them, supply correct identifiers. They help Google match your product to the right searches and comparison surfaces.
• Product category (google_product_category). Set it accurately. The wrong category can put you in the wrong auctions.
• Product type. Use your own taxonomy here. It helps you structure campaigns and report on performance by your own categories.
• Availability and price. Keep these accurate and in sync with your site. Mismatches between feed and landing page are a common cause of disapprovals.
• Condition, colour, size, gender, age group, material, pattern. Supply every attribute that applies to your category. These power Shopping filters and improve match quality.

Pricing and availability accuracy

Google checks that the price and availability in your feed match your landing page. A mismatch can suspend products or your whole account.

• Keep your feed fresh. Use scheduled fetches or the Content API so price and stock updates reach Google quickly.
• Make sure currency and VAT handling in the feed match what the shopper sees on the page.
• Mark out-of-stock items correctly rather than leaving stale availability.

Descriptions still matter

Descriptions are lower weight than titles, but Google reads them.

• Put the most important details in the first 150 to 500 characters.
• Describe the product factually. Include materials, dimensions, use cases and the terms shoppers might search.
• Avoid promotional language ("best price", "buy now"), which adds nothing for matching and can trip policy checks.

Custom labels for campaign control

Custom labels do not affect matching, but they give you control over how you bid.

• Label products by margin, by bestseller status, by season, or by price band.
• Use those labels to split campaigns so you can bid more aggressively on high-margin or high-converting products and pull back on the rest.

Feed hygiene and disapprovals

A clean feed is a feed that actually serves.

• Check the Diagnostics tab in Merchant Center regularly and fix disapprovals promptly.
• Resolve policy issues at the product level before they escalate to account level.
• Watch for missing required attributes flagged as warnings; they suppress products silently.

A practical priority order

If you are starting from a messy feed, work in this order for the fastest gains:

1. Fix any account-level or widespread disapprovals first. A suppressed feed optimises nothing. 2. Rewrite product titles, starting with your highest-spend and highest-margin products. 3. Upgrade main images where they are low resolution or cluttered. 4. Fill in missing attributes, prioritising category, GTIN and the filter attributes for your category. 5. Add custom labels and restructure campaigns around margin and performance.

The bottom line

Feed optimisation is where you control which searches you win and how well you convert them. Titles and images do most of the heavy lifting, attributes power matching and filtering, and clean hygiene keeps everything serving. Pair a well-optimised feed with an authorised CSS for around 20% lower CPC, and you are getting the most out of every Shopping euro.
