When selling auto parts online, product images aren't just pretty pictures—they're the digital equivalent of customers holding the part in their hand. After managing Google Shopping campaigns for numerous automotive clients, I've seen firsthand how image quality can make or break listing performance.
Google enforces specific image standards for auto parts that directly impact your visibility and conversion rates. These requirements aren't random rules but designed to help shoppers clearly see what they're buying, which is crucial when fit and compatibility are key concerns.
In this guide, I'll walk you through the technical requirements, common disapproval reasons, and proven optimization strategies to help your auto parts listings shine in Google Shopping.
Success in Google Shopping starts with understanding the fundamental technical requirements for your auto parts images. These specifications form the foundation of any successful product listing, especially in the automotive category where precise part identification is crucial.
Google has established clear guidelines for image size, format, and URL structure that all auto parts merchants must follow. Meeting these requirements is your first step toward approval and visibility.
Google sets specific size parameters for product images, with particular considerations for auto parts due to their detailed nature.
At a minimum, all auto parts images must be at least 100x100 pixels to be accepted in Google Merchant Center.
However, meeting the minimum requirement isn't enough for competitive listings. While 800x800 pixels serves as a standard baseline, the recommended resolution for auto parts is now 1500x1500 pixels to showcase the fine details that customers need to see.
Be careful not to exceed the maximum limits, though. Google caps image resolution at 64 megapixels with a file size limit of 16MB.
The following table summarizes the image size requirements for auto parts in Google Shopping:
From my experience working with performance auto parts retailers, images closer to the recommended 1500x1500 pixels consistently outperform those meeting only minimum requirements.
Google Shopping accepts several image file formats for auto parts listings, giving merchants flexibility in how they prepare their visual assets.
The platform supports JPEG, PNG, GIF, BMP, and TIFF formats for product images.
Additionally, the WebP format is now supported, which can provide better compression while maintaining image quality—a valuable option for detailed auto parts images with many visual elements.
In some limited cases, Google makes exceptions for placeholder images with auto parts like paint colors or components that are visually identical across variations.
When choosing between formats, consider these factors:
Image Format
In our campaigns for automotive clients, I've found JPEG and PNG formats to be the most reliable choices, with WebP gaining popularity for its efficiency.
The URL structure for your auto parts images must follow specific technical requirements for Google Shopping to properly access and display them.
All image URLs must begin with either http:// or https:// (with the latter being strongly preferred for security reasons).
Any special characters in your image URLs must be properly URL-encoded to prevent crawling issues. This is particularly important for auto parts with model numbers or specifications in the file name.
In your product feed, you'll need to include the direct image link in the [image_link] field, with the option to add multiple angles using the [additional_image_link] attribute.
Here's an example of properly structured image URLs for auto parts:
When working with our automotive parts clients, I always recommend using consistent naming conventions for image files and implementing proper URL structures from the start to avoid feed errors.
Beyond technical specifications, Google maintains strict guidelines about what can and cannot appear in your auto parts images. These content requirements ensure shoppers can clearly see the product without distractions.
For auto parts sellers, understanding these content guidelines is essential to prevent disapprovals and maintain a professional appearance in search results.
Google prohibits certain elements in product images that can mislead shoppers or distract from the actual part being sold.
One common issue is promotional overlays such as "Free Shipping" or "50% Off" text added to images. These are explicitly prohibited and will cause your listings to be disapproved.
Generic placeholder images are also not allowed for most auto parts. The exception is for software products, icons, or parts that are truly identical across variations.
Additional elements that should be avoided include:
I've seen many auto parts retailers struggle with these requirements, especially when transitioning from marketplaces like eBay that are more permissive about promotional text in images.
To showcase auto parts effectively within Google's guidelines, focus on clean, clear photography that highlights the product's details.
When possible, include multiple angles of auto parts using the additional_image_link attribute. This is especially important for complex components where customers need to verify fit and compatibility.
For optimal performance, follow these content best practices:
These approaches help potential customers verify they're ordering the correct part, which is crucial in the automotive aftermarket where fit issues can lead to high return rates.
Understanding why Google might disapprove your auto parts images helps you avoid common pitfalls that can delay your listings or reduce their effectiveness.
I've helped many automotive clients troubleshoot disapproved listings, and image issues are among the most frequent culprits.
The most straightforward reason for disapproval is insufficient resolution. Any image below 100x100 pixels will be automatically rejected by Google Merchant Center.
Low-resolution images not only risk disapproval but also perform poorly even if accepted. When selling detailed components like sensors or engine parts, higher resolution is necessary to show important details.
A more complex issue some auto parts sellers encounter is AI misflagging, where Google's automated systems incorrectly identify parts as prohibited items.
This happens particularly with parts that might resemble weapons or dangerous components to an AI system. For example, certain exhaust components, specialty tools, or performance parts might trigger automated flags.
When this occurs, you'll need to appeal the decision through Google Merchant Center by explaining the true nature of the product.
Another common disapproval reason is incomplete or misleading imagery for bundled products. When selling a kit or set of parts, the image must accurately represent all components included.
For example, if selling a complete brake kit with rotors, pads, and hardware, your primary image should show all these components, not just the rotors or pads alone.
The following table outlines common disapproval reasons and how to resolve them:
Through our work with aftermarket auto parts retailers, I've found that proactively addressing these issues before submitting feeds saves tremendous time and prevents revenue loss from delayed approvals.
Beyond meeting Google's requirements, implementing these best practices will help your auto parts images stand out and perform better in Google Shopping campaigns.
For auto parts, detail is everything. Customers often need to see specific features to ensure compatibility with their vehicle.
At a minimum, aim for 1000x1000 pixel images for all auto parts to ensure details are clearly visible.
Pay special attention to capturing:
The ability to zoom in on these details can significantly reduce customer questions and returns for incompatible parts.
One of the most underutilized features in Google Shopping for auto parts is the additional_image_link attribute, which allows you to show multiple angles of your products.
Google Shopping allows you to include up to 10 additional images per product using this attribute in your feed.
For auto parts, I recommend including at least these angles when possible:
These multiple views help customers verify the part matches what they need, increasing confidence and reducing returns.
Some of the most effective auto parts images include contextual shots showing the part installed on a vehicle.
Including images of parts in their installed state helps customers understand positioning, fit, and appearance. This is particularly valuable for visible components like lights, grilles, and body parts.
When creating contextual shots:
While maintaining a clean white background for your primary image, these contextual shots in additional images can significantly improve conversion rates by helping customers visualize the part on their own vehicle.
The quality of your auto parts images directly affects your Google Shopping campaign performance. Let's examine the data on how improved images impact key metrics.
High-quality images have a direct correlation with improved click-through rates in Google Shopping campaigns for auto parts.
According to data from Google Merchant Center, listings with clear, high-resolution images that follow best practices consistently outperform those with basic or low-quality images.
This makes intuitive sense—automotive customers need to be confident they're ordering the right part, and clear images provide that reassurance at the critical moment of decision.
For auto parts in particular, visual confirmation is essential in the purchase decision process.

This reliance on visuals is even higher for complex or appearance-related parts where fit and finish are critical factors.
The impact of quality images extends beyond initial clicks to actual purchase conversions.

To clarify, these aren't promotional overlays within the product image (which are prohibited), but rather additional contextual images that showcase the product's benefits in the additional_image_link attribute.
The table below summarizes the performance impact of various image improvements:
Note: These improvements represent industry averages and may vary based on specific product categories and competitive factors.
Google regularly updates its requirements and recommendations for product images. Staying current with these changes is essential for maintaining compliance and competitive advantage.
In recent updates, Google has increased its recommended image resolution for auto parts from the previous standard.
The latest recommendation for optimal performance is now 1500x1500 pixels, up from previous standards.
This increase reflects both improvements in online shopping interfaces and consumers' expectations for detailed product views, particularly important for auto parts where small details matter.
Google has also strengthened its enforcement of policies regarding text overlays in product images.
Recent algorithm updates have improved detection of promotional text and watermarks within images, leading to more stringent enforcement of clean image requirements.
For auto parts sellers who previously used text-heavy imagery, this means updating product photos to comply with current standards is increasingly urgent.
Based on current trends, we can anticipate further refinements to image requirements that auto parts sellers should prepare for:
Staying ahead of these changes by implementing best practices now will position your auto parts listings for continued success.
