How to optimise Google Shopping product titles

A Google Shopping product title is the title value in your Merchant Center product data: the line a shopper reads under the image, and the text Google matches to searches.

Optimising it means putting the identifying details first, each one true for that exact variant. I counted the 11 example titles in Google’s title specification on 27 October 2026: their median is 41 characters of the 150 allowed. I checked each of Google’s rules here against the same page.

What are Google’s rules for Shopping product titles?

Google requires Shopping product titles of 1 to 150 characters that describe the same product as the landing page, name the variant’s details and carry no promotional text. A title that breaks a minimum requirement gets the product disapproved (Merchant Center title specification).

Fix eligibility before wording: a better title can’t help a disapproved product. The Merchant Center errors guide covers the issues to clear first.

Some product types have extra title rules of their own:

The rest of the specification is advice: use all 150 characters, put the most important details first, and add keywords such as the brand or “maternity” for apparel.

How long should a Google Shopping title be?

A Google Shopping title should be as long as its true details need, up to 150 characters, with the essentials in the first 70. Google says shoppers usually notice only the first 70 or fewer.

Google’s own examples don’t fill the space: half of them are 41 characters or shorter.

How long are the example titles in Google's own title specification?

Example title	Characters
AI-generated shoes (structured_title)	74
Shoes	52
Skater dress, small, black	47
Pixel 3 phone	47
Organic cotton T-shirt	46
Camera bundle	41
Android plush toy	37
Software subscription	37
Pixel 4 phone	36
Milk chocolate	22
Dark chocolate	22

The long one is the AI-generated title, which opens with a 17-character tagline, “Stride & Conquer:”. Google’s plain title for the same shoes uses 52 characters and starts with the brand.

Does Google change your product titles?

Yes. Google can rewrite a Shopping title for a search with Product Data Customization, using your landing page, images and other signals. When your title already fits the search best, it stays.

The rewrite draws on your own title, landing page and images, so accurate data there still decides what shoppers see. To opt out, ask your Google account manager or support team; Google says requests typically take 3–5 business days.

Which details should a Google Shopping title include?

A Google Shopping title should include the details a shopper uses to choose: product type, brand or model, and what separates this variant. The category decides which ones.

For example, with fictional brands (illustrative data), the patterns turn these titles into ones a shopper can choose from:

Fill each pattern with the words from your Shopping search terms report. Writing titles from shopper searches maps those words to attributes.

Worked example: one title from its feed attributes

Take a fictional brand, Aster, which sells a hiking boot called Trail 2. Its title is the model name alone, “Aster Trail 2”, which says neither what it is nor who it fits.

The new title is “Aster Trail 2 Men’s Hiking Boots, Black, Size 42”: 48 characters, all inside the visible 70.

Leave out “waterproof” and “best”, which the product data can’t support, and “free delivery”, which Google bans from titles. An unsupported claim is a misrepresentation risk.

How should titles handle product variants?

Each variant gets its own title with its distinguishing details, repeated in the matching attributes such as color, size and age_group. Variants share one item_group_id; each keeps its own ID, title and landing page. A title can change; the id never should, or the product loses its history.

Google’s skater dress example shows the pattern:

When a variant detail has no attribute, it goes in the title only. Google’s example is chocolate: “Organic milk chocolate” and “Organic dark chocolate” differ by flavour.

The landing page should open on the variant in the title, with that colour and size selected. A shopper who clicks “Black, Size 42” and lands on brown size 44 leaves.

How do you implement and check a title change?

A title change is done when the new value reaches the processed product in Merchant Center, describes the exact variant and matches the landing page. Saving the text is step two of six.

Where you make the change decides what else it touches:

Attribute rules (formerly feed rules) and supplemental sources both need the Advanced data source management add-on in Merchant Center (attribute rules). A supplemental source updates products that already exist; it can’t add or remove them.

For example, an attribute rule that sets title to brand, the model, gender, product_type, color and size builds the Aster title for every boot. Before applying it, test the draft and preview a product without a size: the rule still runs when one input is missing, so look for a title ending in “, Size”.

When titles come from a product information system, the PIM-to-Merchant Center workflow keeps source and submitted value in step.

For feed problems beyond titles, use the Google Shopping feed optimisation guide.

How do you test whether a new title works?

Test a new title on a group of products against a similar group you leave unchanged, over the same weeks, on orders and contribution after ad cost. A before-and-after read also picks up season, price and stock.

For example, a merchant changes the titles of 40 products and leaves 40 similar products alone. Clicks on the changed group rise 20%, which looks like a win.

Change over a title test: changed titles vs unchanged titles

Metric	Changed titles	Unchanged titles
Clicks	20%	12%
Orders	10%	9%
Contribution after ad cost	6%	7%

Against the unchanged group, the title added 8 points of clicks, 1 point of orders and 1 point less contribution. It drew clicks that didn’t buy.

Read the result after late conversions have come in, with budgets and prices held steady. A narrower title that filters out unsuitable clicks can win while the clicks chart looks worse.

Picking comparable groups by hand across thousands of products doesn’t scale. Product Segmentation segments every product on advertising clicks and return (ROAS or POAS) and writes the segment to a Merchant Center custom label.

Draw both groups from the same segment. Question Marks and Dogs get clicks but return less, so they are the first to test.

Can you write Google Shopping titles with AI?

Yes, in the structured_title attribute with its source type set to trained_algorithmic_media. Google requires that for every title written with generative AI; other titles can use either attribute.

If a product has both title and structured_title, Google uses title. Remove the plain title, or your AI-written one is ignored.

Give the model the product’s attributes and nothing else, then check each title against them. A model that calls the Aster boot “waterproof” writes a claim you would never type yourself.

Final thoughts

A good Shopping title describes one variant accurately, in the order a shopper scans it. The 150 characters are room for true details, not a target.

Start with the twenty products that get the most clicks, rewrite their titles from their attributes, and test them against twenty you leave alone.
