เครื่องมือตรวจสอบข้อความ alt ของรูปภาพคืออะไร?

กรณีการใช้งานทั่วไป

• Auditing a marketing landing page before launch to confirm no hero or product <img> ships without an alt attribute.

• Spot-checking a competitor's or client's live page to gauge how seriously they handle image accessibility.

• Triaging an accessibility complaint by getting a fast list of images that screen readers would announce as unlabeled.

• Reviewing a CMS template after a redesign to catch images where the author left the alt field blank.

• Building an SEO punch list, since search engines use alt text to understand images and missing alts waste that signal.

• Verifying that decorative images intentionally use alt="" rather than accidentally omitting the attribute entirely.
