Meta refresh and JavaScript redirects can work, but server-side redirects such as a 301 are faster, clearer and more reliable. Search engines can follow the other types, though they add delay and more room for error. Use them only when you cannot change server settings.
Server-side redirects
A server-side redirect happens before the page loads, using a status code such as 301. Browsers and crawlers understand it immediately, which is why it is the preferred method for moving pages.
Meta refresh redirects
A meta refresh is an HTML tag in the page that sends visitors on after a set delay. Search engines can follow it, but the page must load first, and visitors may see a flash of the old page. It is a fallback, not a first choice.

JavaScript redirects
A script changes the address after the page loads. Google can process these when it renders the page, but it is slower and depends on the script running correctly. It can fail if scripts are blocked or broken.
When each is acceptable
- Server 301: any permanent move.
- Meta refresh: only where server access is impossible, such as some hosted platforms.
- JavaScript: for app behaviour, not for moving indexed pages.
How to check what you have
View the page source for refresh tags and test the address in the redirect and status code checker. It will show server-side hops, so a page that looks redirected but shows a 200 is probably using one of the other methods. The HTTP header checker shows the raw response.
Fix it
Replace the tag or script with a server rule, which you can produce using the htaccess redirect generator. Keep it to a single hop, as explained in redirect chains and loops.
Frequently asked questions
Is a zero-second meta refresh the same as a 301?
Not exactly. It may be followed, but it does not behave as cleanly as a real status code.
Can I use JavaScript for A/B testing?
Yes, but keep the original address indexable and the final result clear.
