Product Titles and Descriptions for Google Shopping: Rules, Structure and Examples

The title is the most visible part of a Shopping listing and one of the main signals Google uses to understand what you sell. The description adds the detail behind it. Both have firm rules, and breaking them can lead to issues; following them well helps products match specific searches.

This guide covers both attributes: limits and requirements from Google’s documentation, practical structures by product type, before-and-after examples, how to handle AI-written text, and how to roll out changes across a catalog.

Title requirements at a glance

Google’s title attribute documentation sets these rules. The title is required for every product and corresponds to Product.name in schema.org markup.

Rule	Requirement
Length	1 to 150 characters; longer titles are truncated and get a warning
Accuracy	Must describe the product shown on the landing page
Variants	Must distinguish variants; include details like color, size or flavor
Specificity	Be specific about what the product is
Grammar	Professional grammar; no all caps for emphasis, symbols or HTML tags
Promotional text	No promotional text, price, sale wording, shipping or delivery dates, or other time-related information
Company name	Don’t include your company name
Whitespace	No extra spaces
Language	The majority must match the language of the data source; no gimmicky foreign characters

How Google suggests structuring titles

Google’s best practices are short and practical:

• Use the space available: up to 150 characters.
• Put the most important details first. Google notes shoppers usually notice the first 70 characters or fewer.
• Include keywords shoppers would use: the product name, brand and specific details such as “maternity” or “waterproof”.
• Include the brand where it helps differentiate the product.

Practical title structures by product type

These patterns are practitioner templates built on those principles, not Google requirements. Adjust the order to put whatever shoppers compare first at the front.

Product type	Suggested order
Apparel	Brand + gender or age group + product type + key attribute (material, fit, style) + color + size
Electronics	Brand + product line + model + product type + key spec
Home and kitchen	Brand + product type + key attribute (material, capacity, dimensions) + color or finish
Beauty and personal care	Brand + product name + product type + key attribute (skin type, scent) + size or volume
Auto and hardware parts	Brand + part type + compatibility or part number + key spec
Handmade or custom	Product type + material + style or design + size or color

Title examples: before and after

The products and brands below are invented, purely to illustrate the patterns.

Before	Problem	After
SALE!!! Cozy Sweater FREE SHIPPING	Promotional text, symbols, all caps, vague	Northvale Women’s Merino Wool Crew Neck Sweater, Forest Green, Medium
Model BX-27U	No product type or brand; meaningless to shoppers	Brightline BX-27U 27-Inch 4K Monitor, USB-C, Height-Adjustable Stand
Dutch Oven | Best Price | Shop Kettle & Co.	Price claim, company name, symbols	Kettle Craft Enameled Cast Iron Dutch Oven, 5.5 Qt, Cherry Red
Running Shoes	Doesn’t distinguish variants	Strideline Men’s Trail Running Shoes, Waterproof, Black, Size 10
Handmade Mug	Too generic to match specific searches	Handmade Stoneware Coffee Mug, Speckled Glaze, 12 oz, Sage Green

Notice what the improved titles do: each says what the product is, includes the details a shopper would filter by, and puts the variant (color, size) in the title. Nothing in them would need changing when a sale starts or ends.

Variants in titles

Each variant is a separate product in your feed, so each needs its own title. Google requires titles to distinguish variants, and asks you to also submit variant attributes such as color, size and age_group. For products like food, include design elements such as flavor in the title.

Variant titles should match what the landing page shows when that variant is selected. Google’s item group ID rules list title among the values that must match the page for each variant. The full setup is in how to manage product variants in feeds.

Practitioner tip: if your platform uses one product name for all variants, build variant titles in the feed by appending the variant values (for example, title + “, ” + color + “, ” + size) rather than editing hundreds of titles by hand.

AI-generated titles: structured_title and short_title

If you use generative AI to write titles, Google asks you to submit them in structured_title with the digital source type trained_algorithmic_media, rather than in the plain title attribute. If you submit both title and structured_title, Google uses title.

The same applies to descriptions: AI-generated text goes in structured_description. Google notes that a badly formatted structured value can cause a “Too many sub-attributes for the attribute” error.

Two related points from Google’s title documentation:

• short_title is available for Demand Gen campaigns.
• Google mentions a Product Data Customization feature for Shopping ad titles. Merchants can opt out through their account manager or support, which Google says takes 3 to 5 business days.

Description requirements

Google’s description attribute is required and corresponds to Product.description in schema.org. A missing description produces a warning and limited performance.

Rule	Requirement
Length	1 to 5,000 characters
Consistency	Consistent with the title and landing page
Scope	Describe only this product: no accessories, other products, business history or store policies
Promotional text	No price, sale wording, shipping, delivery dates or company name
Comparisons	No comparisons with other products, such as “even better than X”
Categories	No category paths; use google_product_category or product_type instead
Links	No links
Formatting	Professional grammar; no all caps or symbols; escape XML or JSON properly without double-encoding

What to include

Google recommends putting the most important details in the first 160 to 500 characters, and covering features and visual attributes: size, material, intended age range, special features, technical specs, shape, pattern, texture, design and variant details.

Description example

An illustrative description for the invented sweater from the title examples:

It leads with what the product is and what it’s made of, then covers fit, details, the variant, care and measurements. There’s no mention of price, delivery, the store or other products. Practitioner tip: start from your product page copy and remove anything that isn’t about the product itself, such as shipping banners and policy text that some themes include in the description field.

If your store sells used or refurbished goods, Google suggests using the words “new”, “used” or “refurbished” in the title or description so it can cross-check the condition attribute.

Improving titles across a whole catalog

Rewriting titles one by one doesn’t scale. There are three main routes, from most to least durable:

Route	How it works	Watch out for
Fix in your platform	Improve product names and variant data in Shopify, WooCommerce or your product system	Product page H1s change too, which is usually good but worth checking
Attribute rules	Prepend, Append, Find & Replace or Set to on the title attribute in Merchant Center	Needs the Advanced data source management add-on; test before applying
Supplemental data source	A sheet or file with id and a new title, matched to the primary source by ID	IDs must match exactly; feed titles can drift from page titles

Attribute rules are covered in feed rules and attribute mapping, and supplemental sources in supplemental feeds explained. Whatever the route, the title still has to describe the product on the landing page.

A sensible order of work

1. Fix rule breaks first: promotional text, all caps, symbols, company names, titles over 150 characters.
2. Add missing variant details (color, size) so each variant has a distinct title.
3. Restructure titles for products with high click potential, using the patterns above.
4. Improve descriptions that are missing, very short or full of non-product text.

Measuring the effect of title changes

Use Analytics > Products in Merchant Center to compare impressions, clicks and click-through rate before and after a change. Google’s performance documentation explains each metric and lets you filter traffic to ads or organic.

Practitioner tips: change one group of products at a time, note the date, and compare like-for-like periods, since seasonality and price changes also move these numbers. A title change won’t fix a disapproval, a price that isn’t competitive or a weak image.

When to get help

Title and description work is high-leverage but slow across thousands of products.
