Why ScanLyser
How ScanLyser compares
Other tools focus on one dimension. ScanLyser covers all five in a single scan.
Accessibility-only, SEO-only, and overlay tools each cover at most a fraction of these capabilities.
AI-powered
Smarter analysis with AI
ScanLyser goes beyond rule-based checks. AI-powered analysis evaluates content quality, readability, heading semantics, alt text, and meta descriptions - catching issues that automated rules alone would miss.
-
Content quality analysis
Detects placeholder text, thin content, and readability issues.
-
Alt text evaluation
Goes beyond "has alt text" to assess whether descriptions are actually useful.
-
SEO content gaps
Identifies missing topics and semantic relevance issues in your content.
Content Quality
3 pages contain placeholder "Lorem ipsum" text that should be replaced with real content.
Alt Text
12 images use generic alt text like "image" or "photo" — recommend descriptive alternatives.
Heading Semantics
About page skips from H1 to H4, breaking the document outline hierarchy.
Meta Descriptions
5 pages share identical meta descriptions — unique descriptions improve click-through rates.
