A homepage might say "Book a free call", the pricing page "Get started", the footer "Contact sales" and the blog "Talk to us". Four labels for one action. A free brand audit of your page copy will flag this on one page; this script shows it across the whole site.

Reading the output

  • One target, several labels: pick one label and use it everywhere.
  • One label, several targets: "Get started" that sometimes opens a form and sometimes a pricing page confuses people.
  • Vague labels: "Learn more" and "Click here" tell the user nothing.

Limits

This reads server HTML only. If your buttons render with JavaScript, extract the rendered DOM first. Class-name matching is a heuristic; adjust the regex to your theme.

Combine the inventory with a tone check per page. The blunt single-page roast in the War Room gives a quick blunt read of a single page if you want a second opinion.
