What Information Should Image Links Contain During Routine Website Checks?

Why Are Image Link Details Important?

In routine website checks, image links typically refer to the alt attribute, title attribute, and image file names of <img> tags. These details not only affect user experience (e.g., displaying alternative text when an image fails to load) but also influence how search engines interpret image content. Proper settings can enhance the visibility of images in search results, while meaningless stuffing may have negative effects. Therefore, understanding what information to include is essential.

Alt Attribute: Core Content Description

The alt attribute is the most important text alternative for an image. During routine checks, it is recommended to include the following in the alt attribute:

• Main content of the image: For example, "red smartphone front view" instead of just "phone".
• 1-2 relevant keywords: Naturally incorporate page topic keywords into the description, but avoid forcing unrelated terms.
• Image function: If the image is a button or icon, describe its function, such as "search button".

Avoid using meaningless words like "image" or "photo", and do not stuff multiple keywords or repeat the page title in the alt attribute.

Title Attribute: Supplementary Information or Hints

The title attribute provides additional information, typically displayed on mouse hover. During routine checks, consider including:

• Image name or brief description: For example, "2025 new smartwatch preview".
• Link destination: If the image is clickable, hint where it leads, such as "View product details".
• Copyright or source (optional): For example, "Image provided by partner", but generally not recommended for direct display in the user interface.

Note: The title attribute is not mandatory and should not be added to every image. Use it only when the information shown on hover is helpful to users.

Image File Names: Concise and Keyword-Rich

File names also serve as clues for search engines to understand images. During routine checks, it is recommended to:

• Use descriptive file names: For example, "blue-widget-side-view.jpg" instead of "IMG_1234.jpg".
• Separate words with hyphens: This makes it easier for search engines to recognize.
• Avoid overly long names or meaningless characters: Keep it concise for easier management.

Common Mistakes and Precautions

Issues often encountered during routine checks include:

• Repetitive alt attributes or similarity to surrounding text: This wastes optimization opportunities; aim for uniqueness.
• Adding excessive text to decorative images: For purely decorative images, it is recommended to leave the alt attribute empty (alt="") to avoid interfering with screen readers.
• Overusing the title attribute: Unnecessary title attributes can create redundancy and may be seen as spam by search engines.

It is advisable to check website images quarterly to ensure that all important images have accurate alt descriptions and standardized file names. For key assets like product images and service graphics, pay extra attention.

Summary

During routine website checks, the alt attribute of image links should focus on describing content and naturally incorporating keywords; the title attribute is optional for supplementary hints; file names should be concise and include keywords. Avoid stuffing, repetition, and meaningless content. These practices align with user experience and help search engines understand images, but remember not to sacrifice readability and authenticity for optimization.
