Definition: Image Alt Tags, also known as alternative text or alt attributes, are HTML attributes applied to image tags to provide a textual description of the images. They serve as a placeholder text that displays if the image fails to load, ensuring accessibility and enhancing user experience.
Purpose: The primary function of Image Alt Tags is to improve web accessibility for users with visual impairments by providing descriptive text that screen readers can interpret. Additionally, they contribute to better search engine optimization (SEO) by allowing search engines to understand the content and context of images, which can aid in improving website rankings.
Best Practices: Effective Image Alt Tags should be concise yet descriptive, accurately reflecting the content of the image while incorporating relevant keywords where applicable. Avoid keyword stuffing and redundant phrases like "image of" or "picture of," as they do not add value and may negatively impact SEO efforts.
