- The image
- The surrounding page content
- A way to edit the image’s alt attribute or equivalent
Poradnik krok po kroku
Identify the image’s purpose
Ask what the image adds to this page. A tutorial diagram, a product photo and a decorative texture have different roles.
Write the useful information
Describe the key subject or result in plain language. For a tutorial, include the relevant state or action rather than every visible detail.
Avoid repeating nearby text
Keep the description focused. If a nearby caption already explains part of the image, use the alternative text for the information still needed.
Handle decorative images appropriately
If the image is purely decorative, use the platform’s decorative-image setting or an empty alt attribute as appropriate. Do not fill it with unrelated keywords.
Read the page without the image
Review the surrounding text and the alternative text together. Confirm that the essential meaning still makes sense.
Wskazówki i rozwiązywanie problemów
- Complex charts or diagrams may need a longer text explanation nearby.
- Alternative text is not a place for keyword stuffing.
