Benefits of using Google Merchant Center

You might be wondering what GMC is used for. Let’s look at this tool’s significant benefits:
- Give businesses the ability to post and update product information, including images and prices, so that it will appear in relevant Google Shopping searches.
- Provide comprehensive monitoring and management over Google-based marketing and e-commerce. Google Merchant Center also interfaces with other Google services, such as Google My Business.
Next, Mega Digital will show you how to create a GMC account and a data feed for your products step-by-step.
What is a Google Merchant Center feed?
A Google Merchant Center feed is like a spreadsheet with important details about your products. It helps Google understand your products better and create ads for them in Google Shopping. You don’t have to choose keywords or write ads because Google generates ads based on the feed. Each section in the feed provides important details for Google to match your product to shopper searches. The key sections are product title, image, and category.
Product title

You should focus on your product title when you want to improve your Google Merchant Center feed. Why is it important? Because Google examines the product title first to decide which products match a shopper’s search. If your product title isn’t optimized, it’s unlikely that your product will be shown to people who want to buy it.

Product image

The product image is your product’s picture displayed on the left side of your product title. It is an essential component of your Google Merchant Center feed because People don’t click on ads with poor-quality images. To gain a new customer’s trust, you need to present a good and professional image, as it sets the first impression.
Product category
While your product title and image are visible to users, your product category is a behind-the-scenes attribute in your Google Merchant Center feed. Only Google uses it to understand which products are relevant to a user’s search. Your customers won’t see this information directly.
Here’s an example to illustrate the importance of product categorization. Suppose you sell bicycle shorts. You could categorize them as:
Suppose you sell laptop bags. You could categorize them as:
Electronics > Accessories > Bags
However, you’ll achieve better outcomes by categorizing them as:
Electronics > Accessories > Laptop Accessories > Laptop Bags & Cases

While Option 1 provides a general categorization, Option 2 offers a more specific classification tailored to laptop bags. By selecting Option 2, you increase the likelihood of your products being shown to customers searching specifically for laptop bags, leading to better outcomes for your business.

Online retailers have a few choices for creating product feeds for Google Merchant Center. There are a few options for online merchants to generate a product feed (data feed) for Google Merchant Center. Let Mega Digital guide you through the whole process.
Creating and optimizing data feeds automatically
In this case, you’ll simultaneously upload a whole feed’s data. Product feeds provide more efficient administration than uploading individual items. This is comparable to getting data from a Google Sheet, except the data will be obtained from a file on your site due to on-site structured data.
For this technique, you must maintain a Google Sheets page updated with all product information, including all required qualities and availability. This method generally offers the most flexibility and room to scale your campaigns.
- Go to the “Feeds” tab and then click to add a new feed.
- Then choose “Scheduled fetch”.
- Share the name of your feed file and set up a fetch schedule. Share the file’s URL and (if your URL is password protected, which it should be) the URL information.

While utilizing this strategy, you should have it “fetch” data at least once every day.
Using the Content API method
We highly advise you to use the Content API upload method. This will send all updated information to Google in real-time. You don’t have to wait for a scheduled retrieve or manually upload files; this integration does everything for you. Businesses should only utilize a single primary feed that serves as a critical data source for Google. This is easy to keep up with and maintain, which makes it an excellent choice. This is what we would do.
Go to the products page and pick “Feeds” then “Content API” to create a new feed.
You can hire an expert to assist you through all of Google’s requirements. With Mega Digital’s Google agency account rental service, we will assist you in setting up everything within a minute. Our 24/7 services ensure to keep up with your product information and that all the updates are correctly displayed in relevant Google Shopping. In addition, this can help you save more time and money focusing on your business.
Using the Content API approach, you may configure several rules to set, extract, or take the most recent product values from your site.

At this point, you may also add numerous nations to this stream, allowing your items to display to clients in new countries. This option is available while watching the primary stream.
Manually uploading a file
This is similar to the Google Sheets concept, except that you will upload the file to Google manually rather than having it collected automatically or on a timed basis. This requires more time and may result in product information delays. It’s worth considering for people with limited product inventories who are overwhelmed by other possibilities.
To get to the “Create a feed” page, follow the above procedures and select “Upload” as your method. All you have to do is submit the file type, which should be no more than 4GB.

Add products to Google Merchant Center
There are two ways to add products to Google Shopping: Add them manually or upload multiple using a spreadsheet.
Add them individually
We suggest using this option if you only have 10-15 products since it could take a long time to set up.
Step 1: Go to your Merchant Center account. Select Products, then click “All Products”.
Step 2: Choose the blue plus sign button.

Step 3: Enter your product identifiers; these include a unique product ID (such as Global Trade Item Numbers (GTINs) and Manufacturer Part Numbers (MPNs). Furthermore, brand names are also examples of standard unique product identifiers.
Not every product has a distinct product identification. But, if your product does have one, particularly a GTIN, using it can assist makes your advertising and listings richer and more straightforward to discover for customers. You will indicate this in the product data if your product does not have a UPI. Ensure you meet the requirement of unique product identifiers: https://support.google.com/merchants/answer/160161?hl=en
Step 4: Follow up on the next, fill in the product name, description, landing page URL, main image URL, availability, price, product category, and brand. We recommend you do keyword research and deeply understand your product to convert the most optimized information.
For example: With the title, you could consider putting in its characteristic, such as for jewelry, there are: Brand + Weight + Shape + Style + Material, so your name should be [Your brand] 14 yellow gold, Pedant, Classic.

Step 5: Provide the price, currency, and availability aligned precisely with your website, as wrong information may lead to being banned.

Step 6 (optional): Moving forward, you can add more detail to your product description, such as its condition, color, sizes, genders, or age groups. Make your edits, then click Save.
Add multiple products by Google spreadsheet
1. Go to Products, choose Feeds, then click the plus symbol.
2. Choose Google Sheets as your primary feed name and method of entry. There are also other methods to connect your data, yet as a beginner, we recommend that Google Sheets be easier for you to access and update your data.

3. You will choose “Create a template.” Choose this choice since it is the simplest.

4. This will create a template in Sheets for you to complete with the required product details.

5. Once you do this, grant Google access to this Sheet. You can manually acquire updates from the feed or schedule a fetch at a certain time.

Optimize your data feed tips
Make a plan for updating your product data feed as product information, availability, and pricing change. This is critical because Google will not display your product ads if your data feed does not match your website. Double-check your data feed with Google requirements: https://support.google.com/merchants/answer/7052112?visit_id=638150511079215006-550135120&rd=1
A good data feed is a critical component of the success of your Google Shopping targeting. Here are a few essential points to remember:
- Assure that your product titles and descriptions are keyword-rich and attractive to a potential buyer viewing your ad. Negative keywords can still be added to Shopping Campaigns to reduce unwanted traffic, but you need to be considered because it can accidentally cut your traffic
- If you’re working with foreign currencies, make sure prices are accurate. If not, Google won’t display your products.
- If you want to advertise in multiple countries, you’ll need a product data feed for each. Shopping Ads Campaigns are country-specific, so you must create a new campaign for each sales country.
- Product images can decide the success of your ads, so make sure they’re high quality! There should be no edited or watermarked product images, and the images should only show the product you’re selling. Images that are “family-friendly” perform best and are less likely to be suspended.
- It’s also great to notice any current promotions you’re running.
- Ensure that all destination URLs point to live pages rather than 404s or dead pages.
