HTML Checker Example Report — Structure, Headings & SEO Validation
This example shows the AIPageSEO HTML Checker for a landing page. The report validates HTML document structure, heading hierarchy, image alt text, meta tags and structured data — finding 2 errors and 4 warnings across 70+ checks with specific line-level fix guidance.
6 images missing alt text
6 <img> elements have no alt attribute. Images without alt text are invisible to screen readers and lose image search ranking potential. Fix: Add descriptive alt text to each image. For decorative images use alt="" to indicate they can be safely skipped.
Heading hierarchy skips H2 → H4
The page jumps from H2 to H4 in two places, skipping H3. This breaks document structure for screen readers and weakens the page outline for crawlers. Fix: Change the H4 elements to H3, or add H3 headings between the H2 and H4.
Title too long — 68 chars (target 50–60)
Your title will be truncated in SERPs. Shorten to under 60 characters keeping the primary keyword at the start: "SaaS Pricing Plans — ExampleApp" is 33 chars and clear.
Meta description too short — 94 chars (target 150–160)
66 characters unused. Expand your description to include secondary keywords and a specific call to action: "Compare ExampleApp plans from £9/month. 14-day free trial, no credit card required. Start today."
2 external links missing rel="noopener noreferrer"
External links opening in a new tab (<a target="_blank">) without rel="noopener noreferrer" expose your page to a security vulnerability (reverse tabnapping). Add the rel attribute to all outbound links.
No schema markup detected
No JSON-LD structured data found. Adding SoftwareApplication schema with pricing information would enable rich results and improve AI citation probability.
