What the Audit Prioritizes

Better image SEOEnhanced accessibilityLower loading timeFewer defective resources

Test area: Images and Media.

Missing alt attribute in the product image

Illustrative values, not customer findings. Existing audit-check L61: Informative images have an alt attribute.

Example URL: https://example.org/produkt/beispiel
Observed value: img_missing_alt = 2: two informative images without alt attribute.
Expectation in the check: img_missing_alt = 0.
When the statement applies: Applies to analyzable images in HTML; correctly marked as decorative images are not a missing attribute.
Limit of the statement: An existing alternative text can still be inappropriate. The count value does not replace an editorial evaluation.

Why this area is important

Images and media influence image SEO, loading time, accessibility and user trust. Hero images, product images and media in important landing pages directly affect perception and technical quality.

Risk without testing

Missing alt texts, defective resources, too large files or LCP-related image problems can worsen visibility, accessibility and performance. In shops and local industries, images are often an underestimated conversion factor.

For whom particularly relevant

Relevant for shops, service providers, hotels, restaurants, real estate, practices, portfolios and all websites with visual proof of performance or product.

Typical findings in the audit

important images have missing or meaningless alt texts
Media resources provide error status or slow responses
Image sizes and formats do not fit the location
Hero or product images burden the first visible area

Recommended implementation

Formulate alt texts for informative images concretely and contextually
Clean up defective or blocked image resources
Optimize formats, dimensions and compression per template
Prioritize LCP-related images and use lazy loading consciously

Frequent Questions: Images & Media

The most important classifications before starting an analysis.

Are alt texts still important?

Yes. Alt texts support accessibility, image understanding and context. You should describe what is relevant to the page content, not just repeat keywords.

Why does the audit also consider images as a performance topic?

Large or incorrectly loaded images are often among the most important loading time problems. This is why Seitenreport combines media quality with performance and UX signals.
