Adding alternative tags (alt tags) and alternative text (alt text) to images used in community forums or articles is an important step in making content more inclusive. Alt tags refer to the HTML attribute, while alt text provides a written explanation of the image. This feature helps members using screen readers understand the image content, even though the alt tag itself remains invisible to users who aren't utilizing such tools.
Important Note
There is no need to include phrases like "image of," "picture of," or "screenshot of" in the alt text. Instead, focus on delivering a precise and meaningful description of the image to ensure clarity for individuals using screen readers or those with visual challenges.
Example of an Alt Tag
Alt tag: Golden sunset over the ocean with waves hitting the rocky shoreline.
Description: A stunning view of a golden sunset over the ocean, with waves splashing against the rugged coastline.
In this example, the alt tag "Golden sunset over the ocean with waves hitting the rocky shoreline" provides a succinct description, ensuring that visually impaired users understand the essence of the scene.Why Alt Tags and Text Are Important
Accessibility: Alt tags offer a textual alternative to images, ensuring users with visual impairments can comprehend the content and its context via screen readers.
SEO Advantages: Search engines rely on alt tags to analyze image content. Adding relevant keywords can enhance search rankings and help users discover the content more efficiently.
Contextual Clarity: Alt tags provide context to the image, ensuring that it complements the surrounding content and delivers the intended message.
Backup Content: If an image fails to load, the alt tag appears instead, giving users insight into what was originally intended to be displayed.
Enhanced User Experience: Proper alt tags contribute to a more inclusive and engaging experience by making content accessible to all users.
Best Practices for Using Alt Tags and Text
Be Descriptive: Use clear and concise descriptions that accurately reflect the image. Instead of generic names like "image1.jpg," opt for meaningful descriptions such as "Team collaborating around a table in a modern workspace."
Consider Context: Think about how the image fits into the overall content and provide details that reinforce its relevance.
Avoid Redundancy: Skip generic phrases like "image of" and focus directly on the description. For example, "Child joyfully flying a colorful kite in the park."
Smart Keyword Use: Incorporate relevant keywords naturally, but avoid overloading the alt tag with them.
Keep It Concise: The description should be brief yet informative, ensuring it effectively conveys the image content.
Handling Decorative Images: If an image is purely decorative and does not provide meaningful content, use an empty alt tag (alt="") to prevent screen readers from focusing on it.
