WordPress adds a shortlink tag to every page head by default:
<link rel='shortlink' href='https://example.com/?p=123' />
. It also sends a shortlink HTTP response header. These outputs were useful in 2010 when link shortening services dominated social sharing. Today, they are unused clutter.
Remove Shortlink for WP PowerSuite strips both the head tag and the HTTP header from your site. Permalinks do not change. Redirects stay intact. SEO URLs stay the same. Only the shortlink output disappears. No settings. No configuration. Enable it once and it runs.
This cleanup module replaces a common functions.php snippet without requiring theme edits or a one-off cleanup plugin. Your HTML gets leaner. Your response headers get cleaner. Your site works exactly the same way.
