Redirects are the invisible plumbing of the internet. Every time a website restructures its URLs, changes domain names, or consolidates duplicate pages, redirects are what prevent the old links from breaking. Without proper redirects, every blog post, backlink, and bookmarked URL pointing to the old location becomes a dead end that shows a 404 error page.
This guide covers the different types of redirects, when to use each one, and how to implement them on the most common hosting platforms.
301 Permanent Redirects
A 301 redirect tells browsers and search engines that a page has permanently moved to a new URL. This is the most important redirect type for SEO because it transfers approximately 90 to 99 percent of the original page ranking power to the new URL. Search engines update their index to replace the old URL with the new one.
Use 301 redirects when you rename a page, move content to a new URL structure, change domain names, or consolidate multiple pages into a single page. If you are restructuring your website, 301 redirects are how you preserve the SEO value you have built over time.
302 Temporary Redirects
A 302 redirect tells browsers and search engines that a page has temporarily moved. The key difference from a 301 is that search engines keep the original URL in their index instead of replacing it with the new one. The ranking power stays with the original URL.
Use 302 redirects when you are running A/B tests, temporarily taking a page offline for maintenance, or redirecting users to a seasonal promotion that will end soon. If you use a 302 when you should have used a 301, search engines may continue indexing the old URL indefinitely and your new URL will not receive the full ranking benefit.
Implementing Redirects with htaccess
On Apache web servers, the most common way to implement redirects is through the htaccess file in your site root directory. A simple 301 redirect uses the Redirect directive followed by the old path and the new full URL. For pattern based redirects that apply to multiple URLs, use RedirectMatch with a regular expression.
For example, if you moved all your blog posts from the root directory into a blog subdirectory and removed a prefix from each filename, a single RedirectMatch rule can handle every post with one line. This is far more maintainable than writing individual redirect rules for each page.
Redirects on Cloudflare Pages and Netlify
Static hosting platforms like Cloudflare Pages and Netlify handle redirects through a special _redirects file placed in your site root. Each line in the file specifies a source path, a destination URL, and a status code separated by spaces. The syntax is clean and readable compared to htaccess regular expressions.
Cloudflare Pages also supports a _headers file for setting custom HTTP headers and a bulk redirect feature through their dashboard that lets you upload hundreds of redirect rules at once. Netlify processes redirect rules in order and supports both path matching and query string matching.
Common Redirect Mistakes
Redirect chains occur when URL A redirects to URL B, which then redirects to URL C. Each hop adds latency and dilutes SEO value. Always redirect directly from the old URL to the final destination, even if the URL changed multiple times over the years.
Redirect loops happen when URL A redirects to URL B and URL B redirects back to URL A. The browser detects the infinite loop and displays an error page. This typically happens when competing redirect rules in different configuration files contradict each other.
Keep Your Links Working Forever
Broken links cost you search rankings, referral traffic, and client trust. Every restructured URL needs a corresponding redirect to preserve the value of every link that was ever shared, bookmarked, or indexed by search engines.
