이 도구에 대해
Review image alt text exports before publishing so accessibility gaps, repetitive descriptions, and over-optimized patterns do not weaken relevance and UX signals.
The Image Alt Text Checker audits alt attributes across your image inventory for missing values, duplicate boilerplate, keyword stuffing, and file-name placeholders masquerading as descriptions. It separates decorative images that legitimately need empty alt from content images that require meaningful text.
- Parses rows in URL|image|alt|context format and normalizes page URLs with an optional base URL.
- Flags missing alt text, duplicate descriptions, generic or filename-style wording, and short or overly long alt copy.
- Supports tracked keyword checks plus repeated-term limits to catch likely keyword stuffing.
사용 방법 Alt Text Checker
Upload a crawl export or paste image data that includes each image URL and its alt attribute. The checker categorizes every image by alt quality, flags rows that are empty when they should not be, and highlights overly repetitive or machine-generated descriptions that need human rewrites.
When this tool is useful
- Audit image metadata exports before launching templates, migrations, or new content hubs.
- Detect missing alt text, duplicate descriptions, and generic placeholders in one QA pass.
- Prioritize image rows where alt text quality, keyword coverage, and accessibility intent are out of sync.
Practical tips
- Keep alt text descriptive and intent-focused rather than repeating the same keyword phrase across many images.
- Use empty alt text only for truly decorative assets and document that intent in your context column.
- Avoid file-name style alt text and rewrite it in natural language that explains the visual meaning.
이 도구를 찾는 이유
Alt text serves triple duty: it powers image search visibility, provides essential context when images fail to load, and is the primary description screen readers announce to visually impaired users. Missing or low-quality alt text means lost ranking opportunities in image search and potential accessibility violations under WCAG guidelines.
