Guidelines For Listing 3C Products

Key Points:

• Use the recommended title structure.
• Fill in all key attributes accurately.
• Use clear, authentic product images.
• Ensure the detail page includes all required sections.
• Avoid absolute claims and misleading information.

• Mobile Phones/Tablets/Computers and Accessories
• Audio devices (headphones/speakers/microphones)
• Smart wearables (bands/watches)
• Household small appliances (for example, routers, set-top boxes, power adapters, chargers, data cables, power banks)
• Other 3C digital electronic products and accessories

Product Title

[Brand] + Core Category + Key Specifications/Parameters + Applicable Scenarios/Devices + Unique Selling Points
Example:
[Apple] iPhone 15 5G Smartphone 256GB, Unicom Network, Dual SIM Dual Standby.

Best Practices

• Brand Name: If a product has a brand, it shall be indicated and be consistent with the brand field in the attributes.
• Core category terms:
  • Mobile phones
  • Tablets
  • Routers
  • Bluetooth earphones
  • Power banks
  • Data cables
• Key specification parameters: Capacity (128GB), power (65W), interface type (USB-C), network standard (5G), size (27-inch monitor).
• Applicable devices: "Compatible with iPhone/Android/laptop" (especially important for accessory products).
• Selling points and features: "Fast charging, noise reduction, Wi-Fi 6, 4K, 120Hz".

What to Avoid

• Absolute terms: "Number one", "Best in the industry", "Lifetime warranty against damage", "Never overheat", "100% non-heating". Using prohibited absolute terms may result in your product listing being de-boosted or removed.
• Obvious false or unreasonable efficacy: "Signal never drops", "Never runs out of power", "Never crashes".
• Brand/Model/Specification inconsistent with the actual situation: Ordinary chargers are labeled as "original official chargers", or incorrect memory/power ratings are marked.
• Unauthorized or infringing "XX lookalike" or "imitation of a certain brand".

Product Attribute

• Attributes are an important basis for buyers to search for products. Providing inaccurate attributes may lead to product removal. The following are the general attributes of 3C products:
• Brand:
  • Should be consistent with the brand information in the title and details.
  • Avoid impersonating well-known brands or using misspellings that are confusingly similar to other brands (such as differing by 1 letter).
• Model:
  • Use official models, such as "iPhone 15", "WH-1000XM5", "RT-AX86U"
  • Self-developed products should have a unified internal naming system to avoid multiple confusing model numbers for the same product.
• Color/Appearance: Use standard color names (Black / White / Silver / Blue), and avoid using non-standard color names such as "Popular Color" as official attributes.
• Compatible Devices:
  • Accurately fill in the applicable devices, especially for accessory products, such as "this phone case is suitable for iPhone 15/16/17";
  • Specify the applicable device rather than the applicable brand. For example, avoid describing the product as "this phone case is suitable for Apple" in this case.
• Size/Dimensions: length × width × height / diameter / thickness.
• Key technical attributes (depending on the product category).
• Mobile phones/tablets: Memory (RAM - Random Access Memory), Storage (ROM - Read-Only Memory), Screen size, resolution, Number of SIM cards, Battery capacity.
• Headphones/Speakers: Connection method (wired/Bluetooth), interface type, whether it supports noise reduction, whether it has a microphone.
• Projector: Resolution, brightness, size, interface type.
• Monitor: size, resolution (1080p/2K/4K), refresh rate, panel type (such as IPS (In-Plane Switching) for better color, TN for faster response, or VA for high contrast), interface type (for example, HDMI, DP).
• Charger/Data Cable/Power Bank: Include rated power, voltage/current range, capacity (mAh), interface type (for example, USB-A, USB-C, Lightning), and supported fast charging protocols (for example, Power Delivery (PD), Quick Charge (QC)).
• Handheld game console: screen size / resolution, battery capacity, supported systems (Android / Windows / proprietary system).
• Smartwatch: screen size, resolution, touch type (full touch / touch + physical buttons), battery capacity/endurance.
• USB Flash Drive / External Hard Drive / Solid State Drive (SSD) External Hard Drive: Capacity (for example, 32GB, 64GB, 1TB), Interface Type (for example, USB-A, USB-C, Dual Interface), and Enclosure Material (for example, Metal, Plastic).
• Router: Frequency band (2.4G/5G), speed, number of antennas.

Best Practices

• Information is true and accurate, without false labeling:
  • Avoid labelling 4G phones as 5G
  • Avoid labeling a 4600mAh battery as 5000mAh
  • Avoid writing the 18W charger as a 65W fast charger
• Key attributes should be filled in (even those marked as "optional" by the platform):
  • Power supply/battery products shall indicate capacity, input/output parameters.
  • Storage classes shall indicate capacity and actual available capacity specifications.
• Consistent with the title and details:
  • If the title claims "256GB", the attribute must be 256GB to avoid inconsistency.
  • Information such as color, model, and interface type should avoid self-contradiction.

Product Images

Best Practices for Main Image

• The main body of the product should be centered, and the main body should occupy the main area of the image (approximately ≥80%).
• The main image should display the core product actually being sold, and should not use only a concept image to replace the physical product.

Best Practices for Other Images

• Physical object images from different angles: front/back/side/top/bottom.
• Close-ups of key interfaces/buttons: interface types (USB-C/HDMI), button layout, SIM card slot.
• For smaller products (such as USB flash drives and data cables), handheld or proportional objects can be used to demonstrate their size. Avoid using PS or AI-generated images to alter the true proportions.
• Screen category: When displaying the screen's visual effects, it should ensure authenticity and not mislead through exaggerated rendering (such as extremely narrow borders or extremely unrealistic brightness).
• Scenario Usage Images:
  • Such as earphone wearing demonstrations, routers placed in homes, usage of laptops connected to monitors,
  • If other expensive equipment or accessories appear in the image, it should be stated whether they are included in the sale or merely for illustration.
• Size Specification: Use wireframes/annotations to show product dimensions (length, width, height), cable length, weight. Use local units of measurement (for example, use inches instead of centimeters).

Practices to Avoid

• Avoid showing other products that are unrelated to the item for sale or may mislead consumers. For example, do not show a set of items (like headphones, a charger, and a case) if only the headphones are being sold.
• Images that are clearly inconsistent with the brand/model (for example, using pictures of the latest model to sell an older version). Using misleading images can lead to product removal.
• Using false comparison images, such as exaggerating the comparison between "before and after signal enhancement" and using fake signal icons.
• The image contains dangerous usage methods (for example, battery exposed to high temperature/near a fire source).
