How to optimize website images

1. 01

   Use an image with a purpose

   The image should explain, demonstrate, identify, compare, or support content.

2. 02

   Export appropriate dimensions

   Do not deliver a much larger file than the rendered size requires.

3. 03

   Choose an efficient format

   Preserve required transparency, detail, and compatibility.

4. 04

   Reserve layout space

   Provide width and height or an aspect ratio.

5. 05

   Write appropriate alternative text

   Describe meaningful function or use empty alt text when purely decorative.

6. 06

   Load responsibly

   Prioritize above-the-fold media and defer lower-priority images.

• The visible page matches the intended topic and audience.
• The page can be crawled, rendered, and indexed when intended.
• Claims, examples, code, and links have been checked.
• The page has a measurable next action or outcome.
• A future reviewer can understand what changed and why.

• Define the purpose and expected result of website images.
• Capture the current state using semantic structure, keyboard operation, focus order, labels, names, contrast, alternatives, errors, and assistive-technology behaviour.
• Identify the source template, component, plugin, content owner, and release path that controls the output.
• Prepare a test case, approval path, backup or rollback method, and post-release verification plan.

• Repeat automated checks, complete the relevant manual task, and record the browser and assistive-technology context.
• Check representative page types and edge cases instead of confirming only the example used during implementation.
• Confirm the change did not create repairing markup without checking the complete keyboard and screen-reader task.
• Record the implementation date, owner, release reference, evidence, and next review trigger.

Search visibility and user value improve when website images answers the real questions people bring to the page. For people implementing or reviewing website changes, that means covering the decision context, observable signals, implementation boundaries, and proof that the result works in production—not repeating a keyword or publishing a longer version of the same incomplete explanation.

Use the page as part of a connected topic cluster. Link the broad concept to focused implementation guides, definitions, checklists, examples, and the Asuruas workflow that can identify affected URLs. The goal is to help a reader move from discovery to a confident next action while giving search systems clear entities, relationships, and page purpose.

• Inspect keyboard and focus behavior.
• Inspect names, roles, labels, and instructions.
• Inspect heading, landmark, and reading order.
• Inspect contrast, motion, media, and error recovery.
