Why Google Shopping Product Images are so important

3 days after hearing information people are likely to remember only 10% of it. However, if a relevant image is paired with that same information, people retain 65% of the information three days later. 

The challenge with online shopping is that people can’t touch or see the actual product. That’s why the role of images is enormous. 

Since customers base their purchasing decision on images, you need to stand out from your competitors in some way.

Grab attention with the image

The image is the largest part of the ad. Many customers typically decide on a product by looking at the following attributes in the following order: image, price, title. In Google Shopping, customers are immediately drawn to an image and then their eyes are drawn to the text.

In other words, the combination of images and text results in better campaign performance, no matter if we refer to a regular Shopping campaign or Performance Max. The image is the most important component of your ad also because that’s the first thing shoppers can compare with competitors.

By selecting the right image you can tell shoppers something important about your product, service or brand. Shoppers Crave for Images as they are easy to digest.

Google image shopping search

In 2024 images are more important than ever, because now your customers can find you by using an image.

The concept of shopping by image has revolutionized the online shopping experience, allowing consumers to explore a whole new way of finding and purchasing products. This innovative approach leverages AI technology to enable users to search for items using images rather than text-based queries.

Google Lens has paved the way for this transformative shopping experience. Through the Google app, users can use their phone's camera to visually search for products, opening up a world of possibilities in visual discovery.

Imagine spotting an eye-catching outfit on a passerby or in a magazine. With image search technology, you can simply take a photo of the item and use it to find similar clothing items online. 

Or when you come across a stunning piece of furniture or home decor in a friend's house or a design magazine, you can now effortlessly explore similar items by using image search. 

Google Shopping requirements for product image

If you want to be found in Google Shopping, there is a simple method: do what Google tells you.

Follow these Google Shopping image requirements: 

Google product image size 

Both too small and too big images will cause an error on your Google Merchant Center account and your listing will not go live. Pay the highest attention to the size requirements that Google provides:

→ Non-apparel images: at least 100 x 100 pixels

→ Apparel image: at least 250 x 250 pixels

→ No image larger than 64 megapixel

→ No image file larger than 16 MB

Image formats

Only the following formats are accepted:

  • GIF (.gif) (non-animated)
  • JPEG (.jpg/.jpeg)
  • PNG (.png)
  • BMP (.bmp) 
  • TIFF (.tif/.tiff)

Requirements for the URL

It is important to remember that Google will look at images and their links using crawlers and an algorithm, therefore getting the URL right is essential. 

The url submitted as [image_link] attribute in your feed must lead to the main image for the product.

The  URL requirements include:

  • The URL must start with either http. or https.
  • The URL must be in line with RFC 2396 or RFC 1738 - examples:
  • Space would be %20
  • A quotation mark (“) is %22
  • An octothorpe (#) is %23

Placeholder images

Placeholder images are not allowed aside from two exceptions: 

  • Within the categories Hardware or Vehicle & Parts. Illustrations are allowed here where necessary.
  • Paint, in any category. With these products, single-color images are accepted.

What to avoid with product images

  • Not allowed: Text on the image 

Since clear images of a product help to inform online shoppers, promotional text on ads is forbidden. If you want to add extra text, utilize the product description section.

  • Not allowed: Broken links

 Google must be able to read the link. If it can’t access the link, it won’t be shown, simple as that. Avoid adding spaces or other unreadable elements to your URL. Also, make sure you double-check the URL is still valid and hasn’t been moved or removed altogether.

  • Not allowed: Watermarks

 A watermark may seem like a great idea for branding but it is an easy way to land yourself disapproval. All items on Shopping ads require an image with an unobstructed view of the product that does not contain additional promotional elements.

  • Not allowed: Generic Images

Beware of the "generic images" disapproval! This happens when for some reason you don't have images for a product and you fill the image_link field with a default image, usually simply your company logo.

Pro Tip:  You can now automatically improve uploaded images. Ensure they meet requirements, and improve overall user experience with automatic image improvements.

Google Shopping images best practises

High image quality is strongly correlated with user engagement and clicks. By improving your image essence, you'll provide a better experience for the users who view your item and you might increase the performance of your Shopping campaigns.

1. Use the right Image

Make sure you’ve got the right images for the right product. This means setting up and parent/child attributes with all the right images too.

It rarely works to show a customer the wrong color, size, etc. Different product variations should have their proper pattern, size, and color annotated within your data feed, and the same goes for images.

If you use a feed tool such as DataFeedWatch you can create a rule that helps you avoid making mistakes such as matching the wrong picture with the wrong product variant.

The images you choose should help answer any questions a shopper has about the look and feel of the product.

2. Use high resolution and appropriate image size

A poor quality image won’t do your product any justice and could steer shoppers away from buying your product. 

Despite Google’s minimum size sitting at 100x100 pixels (250x250 for clothing & apparel) larger, high-quality images typically outperform smaller images.

CPC Strategy suggests using images 800x800 pixels or larger. These are more visually appealing and often depict exactly what the product is/does better than smaller images. 

It’s a good idea to hire a professional photographer to snap perfect pictures especially if your own skills are scarce.

Pro-tip: If you don't have an image suitable to be shown in your Google Shopping ads at the time, you can temporarily exclude some items from your feed - until you get the right images. In the DataFeedWatch tool, you can do this:

3. Focus on the image content

You must accurately represent the item you’re selling - this may seem obvious, but make sure that props or backgrounds aren’t overshadowing the item. It’s a must for your product to stand out.

The main image should be the photography of your product on a white background, so it won’t get lost in the shuffle. 

Whilst you know your product very well, keep in mind that this could be the first time a potential customer has seen it. A shopper may not get a good feel for the actual product and move on to the next listing. 

Note: Google recommends that the product should take up no less than 75% but no more than 90% of the full image.

4. Give your images some retouch

If you are creating the images themselves, for a more professional image, try to get your images retouched.

5. Use additional images

Make use of the additional_image_link attribute and add up to 10 extra images to your listing. Usually, additional images show the product from a different angle or with product staging elements.

Give the shoppers the best possible idea of what they are buying and how can they use it.

If you integrate with an automation tool to manage your Google Shopping feed, adding additional images is very easy. You do it using optional fields.

  • After selecting your shop and channel you just need to choose “Optional Fields” in your Mapping Tab.
  • Then you need to click “Add optional field” and find ‘additional_image_link’ in the pop-up list. It looks like this:
    Remember! You can add more images (up to 10) by adding this field many times in your data feed!
    • You need to click “Add field” in order to confirm your choice.
    • In the end map the added field choosing Rename, and then map the field with your image.

6. Test lifestyle images vs. plain images

Any retailer wants the campaign to be bland and uninspiring. To avoid wasting your ad spending check if the dynamic, lifestyle images suit your product or service better.

There was a social experiment conducted around how people react to images with very interesting results. Participants were presented with shopping ads with both lifestyle images and plain images of a clothing item itself. Out of the random group of people tested, 82% answered that they would be more likely to click on a shopping ad first if the image was of someone wearing the product rather than of the product by itself.

So investigate which: product images or lifestyle images are more suitable and find which works best for your brand.

Pro tip: If you're a Shopify store owner

When adding lifestyle photos for products in your store remember to use the same unique key in your lifestyle image file name.

If you use a DataFeedWatch tool creating your new feed with lifestyle images seems very easy. Configure your image_link attribute to look through your various input fields that may contain the lifestyle image you uploaded.

Below you can see an example of a rule within DataFeedWatch that will get DFW to find the image that contains your unique URL key.

7. Regularly conduct A/B Testing of images

The feed is not just a cold set of data. This concerns especially your product images.  How else you could discover what is the most vital component of your ad if not by making A/B tests.  Check images variations, analyze the results and apply adjustments to improve the performance of your ads. Take the guesswork out of the equation and find out what your customers respond to. 

Have a good overview of your Google Shopping images 

If you're a large company or agency, you'll probably need to manage many products in more than one data feed. Since product images are such an important part of any Google Shopping ad, it's important to have full control over whether all products have images and how good and optimized the images are. 

A good solution here would be using a feed tool like DataFeedWatch, where you can quickly take a look at all product images submitted via the image_link attribute. 

In fact, in our tool we have a section, where you can review all of the attributes that are in your feed, including product images.

To add images to your review section you need to click on 'Customize Columns' and tick image_link to add it to your overview.

In your DataFeedWatch tool you will now be able to see an extra column with an image for each of your products (or no picture in this column if the picture is missing in your feed).

  • use automatic image improvement feature

When you enable this feature, Google will attempt to automatically fix unaccepted images. And if the improvement is successful, the image will be replaced and the offer will be reapproved.

  • reupload feed

  • request manual review if needed

If you feel that this is no error within the feed, you can request a manual review. This can, however, take up to 7 days. Once items in the feed have been reviewed and approved, they can begin to show up within 24 hours.

Note: You may also come across pre-emptive item disapproval. This is where Google has run a manual review of the products and if they find something that doesn’t adhere to the requirements (such as watermarks), you will receive an email asking for the issues to be fixed with examples of products with the issue.

Image_link in Google Shopping data feed

An image link is a web address that, when clicked, takes users to the main picture of a product. To show this image link on Google Shopping, sellers need to use the [image_link] attribute.

Using the main product image with the [image_link] feature is a must for getting your products to appear on Google Shopping in ads and free listings. You have to use an image link for all the main product images to get the products live on Google.

Just remember to use the [image_link] feature only when you submit the main image to Google Shopping. If you want to submit additional product images to Google Shopping, you should use the [additional_image_link] feature.

Yous should also make sure to match the right image url with the right product, especially if you sell different variants. A simple rule can help with this.
