Automated score
Important issues to address
At a glance
Axe rules in a real browser. Not a substitute for manual testing.
Score 50/100 based on automated checks — 1 finding, highest severity: moderate.
What this means: Treat this as a prioritized to-do list from automation—not proof everything is fixed, and not a substitute for manual checks when it matters.
Findings by severity
This report is not indexed by search engines by default.
We list the highest-severity rule types first (critical and serious before moderate and minor). Each card explains how the issue can affect real tasks—forms, navigation, reading text—not just a rule name.
Up to five priority rule types (deduplicated by rule ID). Start here before reading every row in the full breakdown—guides open in plain language, with technical references optional.
Why it matters
Fixing it reduces friction for people using keyboards, screen readers, or zoom.
Ensure that the page, or at least one of its frames contains a level-one heading
Page should contain a level-one heading
Rule ID: page-has-heading-one
Follow this path to turn the report into real fixes, then confirm with a new scan—no account required.
Fix the items above on real user paths
Checkout, signup, contact, and main navigation matter more than obscure pages.
Use our guides where they match
Each “Open fix guide” links to a short article. Browse the issue library for more.
Verify with quick manual checks
Tab through forms and menus; note anything you cannot reach or operate without a mouse. Spot-check with zoom and your OS screen reader if you can.
Run a fresh scan to see if the score moves
Use Run a fresh scan below—each run gets its own link so you can compare before and after without logging in.
Use a checklist for important launches
Pre-launch accessibility checklist covers common gaps automation misses.
Keep improving over time
Fix repeated patterns (headers, cards, nav) before one-off pages. After updates, rescan and keep both report links to see what changed. One automated pass does not catch everything—use it as a structured starting point, not the final word.
Every finding from this scan—open when you need the complete list.
Findings are grouped by category when the scanner provides one. Fix higher severity items in each group first.

Grouped by automated severity. Each rule links to our issue guide when we have a match.
Blocks or severely harms access for some users—fix before release when possible.
None in this bucket for this scan.
Serious findings—often forms, names, or major contrast failures on key UI.
None in this bucket for this scan.
Moderate and minor rules—still worth fixing in templates to avoid repetition.
Pair fixes with the pre-launch checklist and WCAG in plain English.
Methodology, comparison, sharing, and caveats—open when you need them.
Automated checks found many issues or several high-impact ones. Triage by severity and fix templates before one-off pages.
This URL scored 50/100 on our automated summary. For orientation only, we show an illustrative blended average of 62/100 from sample public scans (not a live industry census). Your page is below that reference point (-12 points).
WCAG 2.1 Level AA is the conformance target most teams cite for policy. Automated scans surface many (not all) AA-related patterns; manual testing still covers context, state changes, and complex interactions.
