How to Enrich Product Titles in Google Merchant Center: 3 Steps

Product title enrichment is the process of optimising your Google Merchant Center titles to improve relevance and performance. If you run Google Shopping or Performance Max campaigns, your product feed matters more than most people realise. And within that feed, your product title is the most important attribute.

Google uses your product titles to match your products to search queries. A weak title means missing traffic. A well structured title means more impressions, better click-through rates, and lower costs.

The numbers back this up. A Search Engine Land case study found that keyword rich product titles produced an 18% uplift in CTR, and where there was an exact match between the search query and the title, CTR increased by 88%. And a controlled A/B test conducted by performance marketing agency Socium Media, using DataFeedWatch, found that enriching Google Shopping titles produced a 25% increase in ROAS and a 12.5% increase in CTR compared to the original titles.

If your titles are just pulling default names from your ecommerce platform like "Blue T-Shirt", you're losing sales. Here's how to fix that.

Why Product Titles Matter

According to the Google Merchant Center's rules of 2026, you first need to understand these.

The basics:

• Titles have a strict 150 limit
• Google displays only the first 70 characters on screen before cutting off
• ALL CAPS will get your items disapproved
• Promotional text like "Free Shipping" or "20% Off" is not allowed in titles

Google's algorithm reads your title to match user queries. So getting this right is the most direct way to improve your Google Shopping performance.

Frequently Asked Questions

What characters are prohibited in titles?

You cannot use promotional language, ALL CAPS, HTML tags, or special symbols like !, $, or *. Google's product data specifications also prohibit gimmicky punctuation and excessive capitalization.

How many characters are displayed on mobile?

Google typically shows around 70 characters on both mobile and desktop before truncating with an ellipsis. This attribute is why front loading your most important keywords matters.

Do titles need to match my website exactly?

Not exactly, but they should describe the same product. Google recommends keeping your titles consistent with your landing page to avoid a poor shopper experience.

Pros and Cons of Title Enrichment

‍

Step 1: Use the Right Structure for Your Product Category

The structure of your title determines how well Google can match it to the right search queries. Getting it wrong means showing up for irrelevant searches or not showing up at all.

There is no single formula that works for every product. What you include depends on what you sell. Start by mapping the key attributes for your category. Think or, color, size, material, gender, or model number. Then combine them in the right order.

Here are some structures that work:

Common Title Mistakes vs Best Practice

Step 1 FAQ

Do I need to include every attribute in every title? No. Include only the attributes that are relevant to how people search for that specific product. A power tool title requires a model number. A t-shirt title requires the color and size. Focus on what drives the search.

Should my Google title match my website title exactly? Not necessarily. Your website title is written for shoppers browsing your store. Your feed title is written to help Google match your product to search queries. They can differ, as long as both describe the same product accurately.

‍

Step 2: Put the Most Important Keywords First

Your most important information is required to appear at the front of your title. Google cuts off display at around 70 characters, and if your company or product type is buried at the end, shoppers simply will not see it.

This is called front loading, and it is one of the most impactful changes you can make to an existing feed.

How to do it:

• Lead with brand and product type. That is usually what people search for first.
• Push secondary details like SKU numbers or minor variants toward the end. Google still reads them, but they do not require to take up the visible space.

Here is a quick example:

Bad title: Classic Fit V-Neck T-Shirt, 100% Cotton, Navy Blue, Polo Ralph Lauren, Size Large

The company appears too late and gets cut off. The user just sees a generic shirt.

Good title: Polo Ralph Lauren Men's Classic V-Neck Cotton T-Shirt, Navy Blue, Large

The company, gender, and item type are all visible straight away. It matches what someone would actually search for.

‍

Step 2 FAQ

What if my brand name is long? Still lead with it. Brand recognition drives clicks, especially in competitive categories. If the brand takes up 25 characters, you still have 45 characters of visible space for the item type and a key attribute.

Should I use all 150 characters? Yes, where possible. Google recommends using the full character limit to provide as much context as possible. Just make sure every word is useful. Do not pad titles with repeated keywords or filler words.

Test Your Titles and Keep Improving Them

Writing a better title is not a one-off task. The best-performing feeds are the ones that get reviewed and updated regularly.

Once you have a structure in place, start testing different versions to see what actually drives clicks and conversions.

Google recommends running experiments to find out which optimisation approaches work best for your products and audience. For example, try adding color to your apparel product titles and measure how your key performance metrics differ. You can use custom labels in Google Merchant Center to tag different product groups and compare how each performs in your campaigns.

‍

One simple approach is to look at your Search Terms report inside Google Ads. Use tools like Google Trends or Search Console to find queries with proven performance, then check whether those terms appear in your current titles. If they do not, that is a clear signal to update them.

Google's product data specifications change regularly, and prices, availability, and other product details keep shifting dynamically, which is why you need to keep revisiting your feed rather than treating it as something you set up once and leave. Build in a monthly review of your top selling products as a minimum. You can create multiple versions of your product titles and track their performance over time, and you can also use A/B testing to compare two different titles and determine which one performs better, giving each title enough time to collect data before making a decision.

Step 3: Use Feed Rules and Supplemental Feeds to Scale

If you have thousands of products, you cannot rewrite every title by hand. And you should not have to change your website titles either. Those are written for shoppers. Your Google feed titles are written for the algorithm.

You can keep them separate using two tools inside Google Merchant Center.

Feed Rules

Feed rules let you build logic that rewrites your titles automatically using the data already in your feed. If your feed includes separate attributes for brand, color, and size, you can tell Google to stitch them together. Go to your feed settings in GMC, select Feed Rules, and create a rule for the title attribute. Set it to combine fields like brand + title + color + size. Google then builds the enriched title without you touching your website.

Supplemental Feeds

If your product data is messy or missing attributes, feed rules may not be enough. A supplemental feed solves this.

It is usually just a Google Sheet linked to your main feed. Here is how it works:

1. Export your product IDs and current titles
2. Add a new column called title
3. Use formulas like CONCATENATE or AI tools to build optimised titles in bulk
4. Upload the sheet to GMC as a supplemental feed

Google matches the item IDs and replaces your old titles with the new ones.

Step 3 FAQ

How long does it take for title changes to take effect? In most cases, enrichment deployed through a supplemental feed can be live within two weeks. After that, allow another two to four weeks for performance data to reflect the changes before drawing conclusions.

What if I do not have separate attributes for brand and color in my feed? This is exactly what the supplemental feed solves. You can manually add those columns in a Google Sheet and map them to your product IDs without touching your website or ecommerce platform.

The Result

Better product titles give Google better information about your products. That leads to more relevant search matches, higher click through rates, and lower cost per click over time.

Start with your top 20% of products. Apply these three steps and check your impressions and clicks after two weeks. The data will show you whether it is working.
