Use Heading Structure Checker and Landmark Structure Checker as distinct steps in a clear workflow, with practical checks for beginner workflow, quality, privacy, and common mistakes.
Open Heading Structure Checker first when its stated purpose matches the result you need now. Use Landmark Structure Checker only when it solves a separate next task.
This guide is for designers, developers, editors, and site owners. Start with Heading Structure Checker when your immediate task is to check common heading structure issues and receive practical improvement guidance. Move to Landmark Structure Checker only when you also need to check common landmark structure issues and receive practical improvement guidance.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Landmark Structure Checker solves a genuinely different next step.
Both tools sit in Accessibility Tools, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
Check common heading structure issues and receive practical improvement guidance.
Check common landmark structure issues and receive practical improvement guidance.
Inputs: Text, HTML, labels, or checklist input, Primary color or size, Secondary color or size, and Context.
Example: Example: open the Heading Structure Checker, enter a small realistic sample, review the assumptions and result, then refine the input before using the output.
Check: Combine automated checks with keyboard testing, screen-reader review, and current WCAG guidance.
Inputs: Text, HTML, labels, or checklist input, Primary color or size, Secondary color or size, and Context.
Example: Example: open the Landmark Structure Checker, enter a small realistic sample, review the assumptions and result, then refine the input before using the output.
Limit: This automated check can find common issues but cannot certify full WCAG conformance. Include manual testing with keyboard and assistive technology.
Write down the exact format, number, decision, or artifact you need. This prevents unnecessary work and makes it easier to choose between the two tools.
Use representative values or a copy of the source—not your only copy. Remove information the task does not need, especially personal or confidential data.
Check labels, units, assumptions, and selected options. Review the first output before using it as the input to another tool.
The second tool should solve a distinct next task. Do not process the same input twice merely because both tools appear in the same guide.
Validate with non-sensitive sample data, inspect edge cases, and test in a safe environment before production use. For important legal, medical, financial, immigration, academic, or production decisions, confirm with an authoritative source or qualified professional.

Start with Heading Structure Checker when its required input matches what you currently have. Move to Landmark Structure Checker only when it solves the separate next step described in this workflow.
Heading Structure Checker and Landmark Structure Checker have separate purposes, inputs, and outputs. The comparison keeps those roles clear so you do not repeat the same task unnecessarily.
Combine automated checks with keyboard testing, screen-reader review, and current WCAG guidance. Also use the page checklist and the current official source relevant to your decision.
Yes. Each tool works independently. Use only the step that matches your current task, and keep the other as an optional follow-up.
