Redirects don't hurt SEO when done correctly. A properly implemented 301 redirect transfers your page's link equity to the new URL, preserving your search rankings. Problems only arise when you use the wrong redirect type, create redirect chains, or rely on slow HTML-based redirects.
This article covers how each redirect type affects your SEO, common pitfalls to avoid, and 6 best practices for implementing redirects without losing rankings. For a broader overview of redirect types and implementation methods, see our Complete Guide to URL Redirects.
Key Takeaways
- 301 redirects preserve SEO value by transferring link equity from old URLs to new ones. They are the safest choice for permanent URL changes.
- 302 redirects do not transfer link equity. Use them only for genuinely temporary moves like A/B tests or maintenance pages.
- Redirect chains (A redirects to B redirects to C) waste crawl budget and weaken SEO signals. Always point directly to the final destination.
- HTML meta-refresh redirects are the worst option for SEO. Search engines can't read them, and they don't pass any link value.
- A fast, reliable redirect service with automatic HTTPS support minimizes the performance impact that slows down page loads and hurts rankings.

What is a redirect?
So before we dig a little deeper, it might be good to go over some basics. If you're new to all this technical stuff, you might be wondering, what even is a redirect?
A redirect will send users and search engines to a different URL than they initially landed on. So, in other words, a redirect is a way to automatically move your visitors to the right location.
There are many reasons why you'd want to implement a redirect. For instance, because you migrated to a new domain or merged websites, and you want to automatically redirect from the old URLs to the new ones. A redirect ensures visitors will always land on the right page.
Types of redirects you can use
There are different types of redirects you can use. The most commonly used is the 301 redirect, followed by the 302 redirect. If you plan to make permanent changes to the URL of a page, you'll want to use a 301. When making temporary changes, you'll want to use a 302.
- A 301 redirect signals a permanent move. It tells browsers and search engines that a page has been moved permanently and redirects users to the new location. With the permanent redirect, the SEO value is automatically moved to the new URL.
- A 302 redirect signals a temporary move. It tells browsers and search engines that a page has been temporarily moved. This also means the SEO value is not transferred.
Aside from 301 and 302 redirects, there are two more redirects that you can use. These are 307 and 308 redirects. A 308 signals a permanent move, just like a 301. And a 307 signals a temporary move, just like a 302. The main difference between 308 and 301 redirects, or between 307 and 302 redirects, is the way in which the request is made. The use of 308 and 307 redirects over 301 or 302 redirects is not recommended, though. Only if you have a particular use case that specifically suits them.
How do redirects affect SEO?
Redirects can affect SEO in several ways. However, the ways they affect SEO largely depend on the type of redirects that are used. Here's a quick overview of the types of redirects and their influence on SEO.
Permanent redirects (301 and 308)
If you're using 301 or 308 redirects, the redirect will be permanent. This also means that the link value or SEO value from the source URL will be transferred to the destination URL. With a permanent redirect, you can preserve your SEO value. The new destination will simply inherit all link equity, and maintain its visibility in search engines.
Temporary redirects (302 or 307)
302 or 307 redirects are temporary redirects. Using these types will probably have a greater effect on your SEO than using permanent ones. With temporary redirects, the link value will not be transferred from the source URL to the destination URL. Search engines will continue to index and rank the original URL instead of the redirected one. This means the visibility in search engines will not be properly maintained for the new URL.
Meta refresh redirects
Using Meta-refresh redirects, also referred to as HTML redirects, is not advisable. They hurt your SEO in a major way. This type of redirect is implemented on a page level, rather than on the server level. This means search engines can't read them. They won't be able to know where the redirect is pointing to.
General SEO tips for implementing redirects
So, now that you know all about redirects, let's dive into the practical stuff. What's the best approach to the implementation of redirects without hurting your SEO? Here are some SEO tips for implementing redirects.
When a permanent change is made to your URL, make sure you use a permanent redirect. As we’ve discussed above, with a permanent redirect the SEO value of your old URL will be transferred to the new one.
In a redirect chain, a redirect points to another redirect, and then to another. Search engines will generally only follow a maximum of 5 redirects. So it’s best to avoid redirect chains altogether. But if you feel you need to use them, adjust the links placed on the website to mitigate this issue.
Meta refresh redirects (HTML redirects) are much slower than the general HTTP redirects such as 301, 302, 307, and 308. They also don’t pass on any link value, as discussed above.
It’s important to choose a redirect service that maximizes the speed of the redirects. This reduces the chance of users leaving the site because of slow loading times. And this, in turn, will help maintain your SEO value.
Search engines like secure pages. So, always ensure that you redirect to a secure page, with the HTTPS version of the URL. This means your SSL certificates should always be up to date. But don’t worry, a redirect service like redirect.pizza can automatically handle this for you.
Sometimes, websites maintain multiple versions of a website that can be visited. For instance, a version with the www-prefix in the URL and a non-www version of the URL. This can be seen as duplicate content by search engines and will hurt your SEO. If you’d like to keep multiple versions of a URL available for the same page, rather redirect one to the other.

No. When implemented correctly, a 301 redirect preserves almost all of your page's SEO value. It tells search engines that a page has permanently moved and that link equity should transfer to the new URL. Problems only occur when you create redirect chains, redirect to irrelevant pages, or use the wrong redirect type.
A 301 (permanent) redirect is the best choice for most SEO scenarios. It transfers link equity from the old URL to the new one, helping the new page inherit the original page's search rankings. Only use a 302 (temporary) redirect when you plan to restore the original URL later, such as during maintenance or A/B testing.
Not in the traditional sense. A 302 redirect tells search engines the move is temporary, so they continue indexing the original URL rather than transferring link equity to the destination. If you leave a 302 in place for months, Google may eventually treat it as a 301, but this is unreliable. Use a 301 redirect for permanent changes.
The redirect itself works instantly for visitors. The SEO impact takes longer. Search engines typically need days to weeks to recrawl the old URL, follow the redirect, and update their index. For competitive keywords, it can take 2-3 months before you see the full ranking transfer. Keep your redirects active for at least one year.
The redirects themselves are not the problem. What hurts SEO is redirect chains (multiple hops), redirect loops, and redirecting to irrelevant pages. Each hop in a chain adds latency and dilutes the SEO signal. Google follows up to about 5 hops, but best practice is to always redirect in a single step from source to final destination.
