What is Descriptive Alt Text?
Descriptive
alt text, short for alternative text, is an attribute added to an image tag in HTML. This text describes the appearance and function of an image on a page. In the context of
email marketing, alt text serves several essential purposes, enhancing both accessibility and user experience.
Accessibility: Alt text helps visually impaired users understand the content of images through screen readers.
Email Clients: Some email clients block images by default. Alt text ensures that recipients still receive your message even if images are not displayed.
SEO Benefits: While not as impactful as in web pages, alt text can contribute to the overall
SEO of your email campaigns.
Be Descriptive: Clearly describe what the image is about. Avoid vague terms like "image" or "photo."
Keep it Short: Concise descriptions are more effective and easier to read.
Use Keywords: Incorporate relevant
keywords naturally into the alt text.
Avoid Redundancy: Don’t repeat information already provided in the surrounding text.
Examples of Good and Bad Alt Text
To illustrate, here are examples of both good and bad alt text: Good Alt Text: "Red sports car on a racetrack during sunset."
Bad Alt Text: "Car."
Good Alt Text: "Woman holding a cup of coffee in a cozy cafe."
Bad Alt Text: "Woman."
