A single 301 redirect has minimal impact on site speed. However, excessive redirect chains (multiple consecutive redirects) can slow down loading times. To ensure optimal performance, use direct redirects whenever possible. For instance, redirect Page A → Page C instead of Page A → Page B → Page C.
A 301 redirect is used to permanently redirect traffic from one URL to another. It’s commonly implemented when:
- A webpage’s URL changes.
- A website migrates to a new domain.
- Duplicate content needs to be consolidated to a single URL.
- Broken links need to be fixed by pointing to an active page.
The main downside is that returning visitors might not see the latest version of your site immediately. However, this can be managed with appropriate cache purging rules.
Disable the last setting you enabled and check if the issue persists. Use the plugin’s debugging tools to identify and fix the problem.
