Simple 404 Keyword Insertion

Description

Simple 404 Keyword Insertion creates a page called “404-page” on activation. When a visitor hits a 404, the plugin serves that page with a [404-keywords] shortcode replaced by the sanitized keywords from the request URI. This helps create SEO-friendly 404 pages that reflect the content the visitor was looking for.

  1. Upload the plugin to /wp-content/plugins/.
  2. Activate it through the Plugins menu.
  3. The plugin will automatically create a page with the slug 404-page. Edit it to add your preferred 404 message, using the [404-keywords] shortcode wherever you want the request keywords to appear.
Why does my 404 page return a 200 OK status instead of 404?

This is intentional. To serve the keyword-aware page so search engines can index it, the plugin sends a 200 OK (“soft 404”) rather than a true 404 response. This is the plugin’s core behavior. Note that search engines generally discourage soft 404s for genuinely missing content, so enable this deliberately on sites where keyword-aware landing pages are worth more than strict 404 signaling.

How do I customize the 404 content?

Edit the 404-page Page that the plugin creates on activation, like any other Page. Place the [404-keywords] shortcode wherever you want the keywords from the failed request URL to appear.
