Writing effective alt tags involves a few key steps:
Be Descriptive: Clearly describe the image. For example, "A woman holding a smartphone" is more informative than "Smartphone." Keep It Concise: Aim for brevity while retaining essential information. Ideally, alt text should be under 125 characters. Avoid Redundancy: Do not repeat information that is already in the text near the image. Use Keywords: Incorporate relevant keywords naturally to enhance SEO.
