Audit Results
The SERPInsight Image Audit
The "Alt" (Alternative) text attribute is the primary way search engines and screen readers understand the context of an image.
Auditing images manually is tedious. Our tool automates the process by scanning your entire page DOM, extracting every image tag, and categorizing them based on Accessibility (WCAG) and SEO best practices.
How our tool works
-
1
HTML Parsing
We fetch the raw HTML of your URL and parse the Document Object Model (DOM) to find all
<img>elements. -
2
Attribute Analysis
We check specifically for the presence of the
altattribute and whether it contains descriptive text. -
3
Categorization
Images are flagged as Missing (Critical), Empty (Decorative), or Good based on standard accessibility rules.
Understanding Image Metrics
The gold standard. Text that accurately describes the visual content.
For users with visual impairments, Alt Text is the only way they know an image exists.
If alt is missing, screen readers often read the file name (e.g., "IMG_123.jpg").
Spacers or shapes should have alt="" to tell screen readers to ignore them.
Google Images is a huge traffic source. Optimized Alt text helps you rank there.
If an image fails to load, the browser displays the Alt text as a fallback.
