Most WordPress redirect plugins execute on the template_redirect hook, which requires loading the entire WordPress theme and plugins first (adding 200ms+ overhead).
SearchNexa hooks into init, querying its indexed wp_searchnexa_redirects table and issuing 301/302 headers in sub-5ms before heavy queries run.
2. Automatic Slug Change Detection
When you rename a published post or page permalink, SearchNexa detects the URL change and automatically creates a 301 permanent redirect from the old URL to the new slug, preventing accidental 404 errors.
3. 404 Error Log & Remediation
The built-in 404 monitor captures broken internal or referral links. With one click, map any recurring 404 URL directly to a relevant live destination page.
