Writing effective alt text involves a few key steps:
Be descriptive but concise. Aim to describe the image in a way that adds value without being overly verbose. Include keywords relevant to your content but avoid stuffing. This can aid in SEO and make your emails more searchable. Ensure the text is contextually appropriate. The alt text should align with the surrounding content and overall message of the email. Avoid phrases like “image of” or “picture of.” Screen readers already identify these elements as images, so this information is redundant.
