Create concise image descriptions that explain the visual’s purpose without keyword stuffing or repeating nearby text unnecessarily.

Alternative text helps readers who cannot see an image understand its relevant content. The best description depends on context: a chart needs its main takeaway, while a product photo may need the product type and distinguishing feature.

How to approach it

Describe what matters for the page’s purpose and keep the wording natural. Avoid starting every description with “image of” when it adds nothing. Do not cram unrelated search terms into alt text, and do not duplicate a long caption word for word when the two serve different purposes.

Checks before you share

Keep an untouched source file, inspect the exported copy at full size, and confirm that the result suits its intended use. If the image contains private information, check the entire frame and its metadata before publishing.

Frequently asked question

Should alt text include keywords?

Only when they naturally describe the image; accessibility and accuracy come first.
