SEO Redirects Explained: 301 vs 302 Best Practices
Learn SEO redirect basics: 301 vs 302 differences, best practices, tools, and case studies. Avoid ranking drops by using the right redirect for permanent/temporary site changes.
Assuming you have just redesigned your website or moved to a new domain, only to soon see your Google ranking plummet and traffic drop by 40% within a month. You feel confused because you have been following all the "rules" for launching a new website, but later you discovered the problem, which is that you missed a key step: using the correct SEO redirect. This issue is actually overlooked by many people, but its impact is not small: according to the Ahrefs SEO report in 2025, at least 62% of small businesses and marketers abuse redirects (such as using temporary 302 when permanent 301 is needed), resulting in restricted search permissions and revenue losses. Even worse, fixing redirection errors may take 3-6 months of recovery time, which is not short and is an irreversible loss for your business.
The main way to avoid this problem is to understand the difference between 301 and 302 redirects, when to use each redirect, and follow the best practices for SEO redirects. We have also provided a detailed introduction to various aspects of SEO redirects in this article: from what they are and how they affect search engines, to tools for gradually implementing and avoiding errors. Whether you are launching a new website, merging pages, or fixing damaged links, these strategies can keep your website SEO valuable and maintain traffic stability.
What is SEO redirection?
Before delving deeper into 301 and 302, let's first understand what SEO targeting is: essentially, it is a server-side directive that sends users and search engines from one URL to another. Many people also see it as a "roundabout symbol" of the internet. When someone attempts to access an old page (such as Yoursite. com/old blog), a redirect will send them to a new page (such as Yoursite. com/new blog).
Why is SEO redirection a trend?
Redirects not only provide users with a good experience, but they are also very important for maintaining your SEO value:
- Passing on link benefits: When other websites link to your old URL, appropriate redirects will pass the 'link juice' to the new page, keeping your ranking unchanged. If there is no redirect, these links will be broken and your website ranking will definitely not be as good as before.
- Repairing damaged links: 404 error (page not found) can make users feel frustrated and cause rankings to drop. Google's 2025 Webmaster Guide lists damaged links as the primary factor for low crawling efficiency. The redirect will convert the 404 to a functional page.
- Manage website changes: Whether you're rebranding, merging two pages, or simplifying URLs (such as from Yoursite. com/product/blue-shirt-123 to Yoursite. com/blue-shir), redirects ensure that users and search engines find the right content.
LSI Keyword Context: How redirects adapt to SEO
LSI keywords such as "link equity protection" and "crawling budget optimization" are associated with SEO redirection. For example, 301 redirects retain 90% -95% of the link rights (according to Google's 2025 Search Center update), while misused 302 may waste crawling budgets as search engines constantly check old URLs, assuming they will revert back to the original URL.
301 redirect: permanent SEO redirect
A 301 redirect (also known as a "permanent redirect") tells search engines: "This page has been permanently moved, and you need to update your index to a new URL. ”This is the most common and influential type of SEO redirect 301, which is crucial for maintaining SEO value during long-term changes.
What you must know about 301 redirection:
Link equity transfer: As we mentioned before, a 301 redirect will transfer approximately 90-95% of the link equity from the old page to the new page. That's why they are the gold standard for permanent moving.
Index update time: Google usually updates its index to a new URL within 1-4 weeks, but for low permission websites, it may take longer.
User experience: Users rarely pay attention to 301 redirects because their response speed is very fast, and they will basically be automatically sent to a new page within 1-2 seconds.
When will 301 redirection be used?
Here are some scenarios and times where you can use SEO to redirect 301:
- Domain Reshaping: If you change your domain name (e.g. oldbrand. com → newbrand. com), you need to reset the 301 redirect and link each old URL to the corresponding new URL.
- Case study: In 2025, a fitness brand changed its name from "FitGear" to "ActivePro" and implemented 301 redirects on all product pages (e.g. FitGear. com home shoes → Activepro. com/women's shoes). They retained 85% of their organic traffic as redirects passed through link equity, while similar brands that did not use redirects experienced a 40% decrease.
- Page Merge: If you merge two similar pages (such as two blog posts about "Beginner Yoga") into one, 301 will redirect the two old URLs to the new merged page.
- URL Simplification: If you clean up messy URLs (such as Yoursite. com/blog/2023/10/15-yoga tips → Yoursite. com/blog/yoga tips), use a 301 redirect to the new simplified URL.
- Website structure overhaul: When you reorganize the content of the website (for example, moving the "Blog" section to the "Resources" section), 301 will redirect old category pages to new category pages.
How to implement 301 redirection (step by step)
The implementation of this step may vary depending on the platform, but the following are the most common methods:
- WordPress: Use SEO redirection plugins such as redirects (free) or Yoast SEO (advanced). Install the plugin, go to 'redirects', select' 301 permanent redirection ', and then enter the new and old URLs.
- CPanel: Log in to cPanel, go to "redirects", select "301", enter the old path (e.g./old page) and new URL, then click "add"
- HTAccess file: For sites on Apache servers, edit HTAccess file (accessed using tools such as fileZilla) and add the following code:
- Redirects to 301/old page html ：https://yoursite.com/new-page.html
- Pro Tip: Always redirect to the 'related' page and do not send all old URLs to your homepage. For example, redirecting from "yoga tips. html" to "beginner yoga. html" is better than redirecting to the homepage (which can confuse search engines and users).
302 redirect: Temporary SEO redirect
302 redirect (temporary redirect) will tell search engines: "This page has temporarily moved, but it will still retain the old URL in your index because it will be restored soon. ”Unlike 301, 302 does not pass links to new pages as they are only applicable for short-term changes.

Key facts about 302 redirection
- Link equity behavior: Google retains old URLs in its index and attributes most links to it, rather than new pages. That's why abusing 302 (for permanent changes) can lead to a decrease in ranking.
- Use case duration: 302 redirects should be used for 1-30 days. If you need a longer redirection time than this, it may be permanent (using 301).
- User experience: Like 301, 302 is seamless for users as they will be automatically sent to new pages.
When will I use 302 redirection? (Realistic Scene)
Use SEO redirection 302 in the following temporary situations:
- Website maintenance: If you are updating a page (such as editing product descriptions or repairing damaged features) and need to temporarily disable it, please redirect the URL to the "maintenance page" with 302.
- Example: An e-commerce website used a 302 redirect on its "Black Friday deals" page when updating prices. After 24 hours, they removed the redirect and the page retained its ranking because Google knew it was temporary.
- A/B testing: If you are testing two versions of a page (for example, version A and version B of a login page), use 302 to send some traffic to version B. This ensures that Google does not index version B as a permanent page.
- Temporary Promotion: If you want to redirect users to a limited time promotion page (such as the "Holiday Promotion" page that expires in 2 weeks), please use 302. After the sales end, you can delete the redirect and send the user back to the original page.
Errors to avoid when using 302
The biggest mistake with 302 is using it for permanent changes. For example, a study by SEMrush in 2025 found that 41% of marketers used 302 redirects when renaming a domain, resulting in an average decrease of 35% in organic traffic. Always ask: 'Will this redirect last for more than a month?' If so, please use 301.
Best practices for SEO redirection (avoiding unnecessary expenses and waste)
Even if you know the difference between 301 and 302, sometimes a small mistake can affect the results of your SEO optimization in specific operations. You can refer to the following best practices for SEO redirection to achieve successful results as much as possible:
First, check the existing redirects
Before adding a new redirect, it is best to use the SEO redirect checker to review your current redirect. Tools such as Screaming Frog (up to 500 free URLs) or Ahrefs Site Audit can help you achieve:
Find and identify damaged redirects (such as redirecting to a 404 page).
Search for redirect chains (such as URL A → URL B → URL C), which waste budget and slow down user speed. Targeting 1:1 redirection (URL A → URL C directly).
The logo has been misused with 302 (for example, 302 that has been in use for 6 months).
Case study: A 1000 page blog used Screaming Frog to review redirects and discovered 75 redirect chains. Fixing them to a 1:1 direct search can reduce crawling time by 30% (according to Google Search Console data) and improve the ranking of target keywords by 20%.
Avoid redirection loops
The redirect loop (such as URL A → URL B → URL A) is a nightmare for users and search engines as it traps them in an infinite loop, resulting in 404 errors or timeouts.
To prevent this cycle from occurring:
Before setting up a redirect, you also need to carefully check the URL (for example, ensure that you do not redirect the new URL back to the old URL).
After implementation, use the SEO redirect checker to scan the loop.
Redirects to relevant pages (not just the homepage)
As mentioned earlier, 'homepage redirection' (sending all old URLs to your homepage) is a common error. They confuse users (for example, someone being sent to the homepage when searching for a specific product) and confuse link rights. On the contrary:
Redirects the product page to a new version of the same product.
Repost blog posts to similar or updated posts (e.g. redirect the 2023 "SEO Tips" post to the 2025 "Search Engine Optimization Tips" post).
Update internal links after redirection
Redirects can fix external links (from other websites) and user bookmarks, but if you still insist on updating internal links (from your own website) to directly point to the new URL. This will lead to:
Reduce dependence on redirects (faster page loading).
Improve crawling efficiency (search engines do not have to follow redirection to find content).
Professional tip: Use tools such as Sitebulb to find internal links to old URLs. Most tools support exporting lists directly, which makes it easier to update.

Case study: How a small business fixed redirection errors (and restored traffic)
In 2025, a local bakery in Denver launched a new website, but soon they discovered two key redirect errors on the website:
They used 302 redirects to all old product pages (such as oldsite. com/blueberry Muffins) instead of 301 yuan.
They redirect all old blog posts to the homepage (instead of related new posts).
Within two months, their organic traffic decreased by 55% compared to the previous month, and their ranking in "Denver Bakery" dropped from page 1 to page 4.
How will it be repaired in the future?
- Replace 302 with 301: Using their WordPress SEO redirect plugin (redirect), they changed all product page redirects to 301.
- Fixed homepage redirection: They created a 1:1 redirect for old blog posts (e.g. oldsite. com/bakery tips → newsite. com/blog/bakery prompts) instead of sending them to the homepage.
- Reviewed with Screaming Frog: They used free tools to find and fix 12 redirect loops and damaged redirects.
The repaired result:
Organic traffic has recovered by 70% (returning to pre-release levels).
The ranking of "Denver Bakery" returns to page 1 (3rd place).
The sales of product pages from organic traffic increased by 45%.
