Understanding the Photography Category
The Photography category, identified by the Google Product Taxonomy ID 39, is a specialized segment within the broader Cameras & Optics branch. It is designed to house equipment and supplies specifically dedicated to the process of taking, developing, and displaying photographs, rather than the imaging devices themselves. By correctly assigning the ID 39 or the full path 'Cameras & Optics > Photography' to your products, you provide Google with the precise information needed to categorize your inventory accurately within the Google Shopping ecosystem.
What Belongs in Photography (ID 39)
This category is intended for goods that facilitate the production and post-processing of photographs. Examples of product types found in the US market that fit this category include:
- Darkroom equipment: Such as film processors, enlargers, and complete starter kits for traditional chemical film development.
- Studio and lighting gear: This includes portable light stands, adjustable backdrop stand kits, and external flash units that feature wireless remote control capabilities for professional setups.
- Archival and storage supplies: Items designed for the long-term preservation of media, including slide storage boxes, negative storage units, and specialized bulk organizers.
- Mounting and finishing materials: Products used for final presentation, such as archival mounting corners, photo squares, and double-tack adhesive mounting films.
These items represent the core of the category: they are supportive tools that allow a photographer to manipulate light, process film, or organize the resulting prints and slides. Because this category sits at a level below general optics, it focuses specifically on the workflow and maintenance aspects of photography rather than the capture hardware itself.
What Does Not Belong Here
It is important to distinguish this category from its neighbours to ensure your products are indexed correctly. Items that do not belong in Photography (ID 39) include:
- Cameras: If your product is a digital or film camera, it belongs in the 'Cameras' category. Even if the camera is used for photography, the primary function of the device is image capture, placing it in the neighbouring 'Cameras' category.
- Optics: Binoculars, telescopes, rangefinders, and lenses intended for observation or precision measurement belong in the 'Optics' category.
- Camera & Optic Accessories: While this may seem similar, general items like camera straps, lens caps, cleaning kits, or battery grips for cameras should be placed in 'Camera & Optic Accessories' to ensure they appear alongside the hardware they support.
If you are unsure where an item fits, always evaluate the primary purpose of the product. If it is an essential part of the imaging device (like a lens) or a utility accessory for the camera body, choose the accessory category. If it is a tool for darkroom work, studio lighting control, or archiving, use Photography (ID 39).
When to Choose a Subcategory
The Photography category contains several distinct subcategories. You should always opt for the most specific subcategory available rather than the broad 'Photography' ID. For instance, if you are selling a specific piece of equipment for a darkroom, categorize it under 'Darkroom'. If you are selling items for lighting setups, use 'Lighting & Studio'. Using the most granular level possible improves the likelihood that your products are surfaced for relevant search queries. As a best practice, always check the 27 deeper categories within the four main subcategories mentioned (Darkroom, Lighting & Studio, Photo Negative & Slide Storage, and Photo Mounting Supplies) to see if a more precise home exists for your specific inventory.
Implementation in Your Feed
To accurately categorize your products in your Google Merchant Center feed, use the google_product_category attribute. You can utilize the numeric ID or the full path string. Both methods are effective, but the numeric ID is often preferred for feed management because it is language-independent. The values are as follows:
- Numeric ID: 39
- Full Path: Cameras & Optics > Photography
Remember that this attribute is optional. However, relying on automatic categorization can lead to errors. Manually assigning the correct category ensures that Google understands the context of your items. Note that the product_type attribute is a separate, free-form field that you should continue to use for your own internal classification; it does not replace the requirement for a valid google_product_category. Always ensure that your feed data is clean and consistently mapped to these standards to maintain high visibility in Google Shopping.
