Find duplicate headings, same-text links and unnamed repeated landmarks that make a page hard to scan by ear

Repeated labels checkFreeFor developers and designers

15/day

free runs a day, no sign-in.

Before: what you give it

The example input, as typed in. You give it a page address.

<main><section><h2>The longest runs on Broadway</h2><a href="/runs">The longest runs on Broadway</a></section><nav><a href="/">Home</a></nav><nav><a href="/x">Shows</a></nav><a href="/a" aria-hidden="true" tabindex="-1"><img src="a.jpg" alt=""></a><a href="/a">Phantom</a><div id="x"></div><div id="x"></div></main>

After: what comes back

The first lines of a real run on that input. Nothing here is edited by hand.

Source: pasted input. Read 1 headings, 4 named links, 3 landmarks and 1 ids from 13 elements. Skipped 1 headings and links that are aria-hidden or hidden, because a browser leaves them out of the accessibility tree.
Findings: 3 (heading-and-link-same-text 1, unnamed-duplicate-landmark 1, duplicate-id 1).

[MEDIUM] heading-and-link-same-text: "The longest runs on Broadway"
  Heading H2 and link to /runs share the same text, in <section>. Screen reader users hear the phrase twice. Give the link its own wording (what is at the other end), or make the heading the link.
[MEDIUM] unnamed-duplicate-landmark: 2 navigation landmarks, 2 without a name
  Landmark lists show the same word 2 times. Add aria-label to each (for example "Primary" and "Footer"). Unnamed: <nav>, <nav>.
[MEDIUM] duplicate-id: id="x" x2
  On <div#x>, <div#x>. Labels, aria-labelledby and anchors resolve to the first match only.
