Why and When You Need to Implement Website Redirects
Imagine you've just launched a beautiful, redesigned website. The URLs are clean, the structure is logical, and everything is new. But what happens to the old pages that customers have bookmarked and search engines have indexed? Without proper instructions, users will hit a '404 Not Found' error, and your hard-earned search engine rankings will plummet. This is the critical problem that website redirects solve.
A website redirect is a way to send both users and search engines to a different URL from the one they originally requested. It's an essential tool for maintaining user experience (UX) and preserving search engine optimization (SEO) value. You might need to implement website redirects in several common scenarios:
- Website Redesigns or Migrations: When you change your site's structure, platform (e.g., moving to Next.js), or domain name.
- Deleting or Consolidating Pages: When removing a page, you should redirect its traffic to the next most relevant page.
- Fixing Broken Links: To point outdated links to their new, correct locations.
- Vanity or Marketing URLs: Creating short, memorable URLs that forward to a longer, more complex page (e.g., vertex-web.com/promo -> vertex-web.com/services/special-promotion-2025).
This guide will walk you through the entire process, from planning your URL mapping to executing the technical implementation and verifying the results.
Understanding the Key Types of Redirects
Before you begin, it's crucial to understand the different types of redirects and their specific use cases, as choosing the wrong one can negatively impact your SEO.
301 Redirect (Moved Permanently)
This is the most common and important redirect for SEO. A 301 redirect tells search engines that a page has permanently moved to a new location. Consequently, search engines like Google will transfer the vast majority of the old page's link equity (ranking power) to the new page. Use a 301 redirect for any permanent URL change.
302 Redirect (Found / Moved Temporarily)
A 302 redirect indicates a temporary move. It tells search engines to keep the original URL indexed and not to pass any link equity to the new, temporary URL. This is useful for A/B testing page variations or redirecting users to a temporary promotional page without affecting the original page's ranking.
307 and 308 Redirects
These are more technical HTTP 1.1 successors to the 302 and 301 redirects, respectively. The key difference is that they preserve the original request method (e.g., POST, GET). A 307 is a temporary redirect, and a 308 is a permanent one. For most standard website redirection tasks, 301s and 302s are sufficient, but modern frameworks like Next.js often use these for greater precision.
How to Implement Website Redirects: A Step-by-Step Guide
Follow these steps to ensure your URL forwarding strategy is sound, secure, and SEO-friendly.
Step 1: Create a URL Redirection Map
Proper planning is 90% of the battle. Before writing a single line of code, you need to map every old URL to its corresponding new URL. A simple spreadsheet is the perfect tool for this.
- Crawl Your Existing Site: Use a tool like Screaming Frog SEO Spider or Semrush to get a complete list of all URLs on your current website.
- Create a Spreadsheet: Make two columns: 'Old URL' and 'New URL'.
- Map the URLs: For each URL in the 'Old URL' column, find the most relevant corresponding page on your new site and place it in the 'New URL' column. If there's no direct equivalent, redirect to the parent category page or the homepage as a last resort. Never redirect everything to the homepage, as this can be seen as a soft 404 by Google.

Step 2: Choose Your Redirection Method
Redirects can be implemented on the server (server-side) or in the browser (client-side). For SEO, server-side redirects are always the preferred method. They are processed faster and are more clearly understood by search engine crawlers. We will focus primarily on these.
Step 3: Implementing Server-Side Redirects
The implementation method depends on your web server or technology stack. Here are the most common approaches:
Method A: Using .htaccess on Apache Servers
If your website is hosted on a server running Apache (common for many WordPress and PHP sites), you can add redirect rules to your .htaccess file, which is located in your website's root directory.
To redirect a single page (301):
Redirect 301 /old-folder/old-page.html https://www.vertex-web.com/new-folder/new-page.html
To redirect an entire domain to a new one:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^olddomain.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.olddomain.com [NC]
RewriteRule ^(.*)$ https://www.newdomain.com/$1 [L,R=301,NC]Method B: Using Nginx Configuration
For servers running Nginx (known for high performance), you'll edit your site's configuration file, typically found in /etc/nginx/sites-available/.
To redirect a single page (301):
location = /old-page.html {
return 301 https://www.vertex-web.com/new-page.html;
}To redirect an entire domain (server block):
server {
listen 80;
server_name olddomain.com www.olddomain.com;
return 301 $scheme://newdomain.com$request_uri;
}Method C: Using Modern Frameworks (like Next.js)
At Vertex Web, we build many of our high-performance sites with Next.js. This framework has a built-in, elegant way to handle redirects directly within your project configuration.
You can add your redirect rules to the next.config.js file:
// next.config.js
module.exports = {
async redirects() {
return [
{
source: '/about-us',
destination: '/about',
permanent: true, // This creates a 301 redirect
},
{
source: '/services/old-service',
destination: '/services/new-service',
permanent: true,
},
{
source: '/promo',
destination: '/special-offer',
permanent: false, // This creates a 302 redirect
},
]
},
}This method is clean, version-controllable, and easy to manage, showcasing the power of modern web development stacks.
Step 4: Verifying and Testing Your Redirects
Once you've implemented your redirects, you must test them. Do not skip this step!
- Manual Testing: Enter several old URLs from your map into your browser and ensure they redirect to the correct new URLs.
- Use Browser Developer Tools: Open your browser's developer tools (F12 or Ctrl+Shift+I), go to the 'Network' tab, and enter an old URL. You should see the request receive a 301 or 302 status code before forwarding to the new page.
- Use an Online Tool: Use a free online HTTP status code checker to test a list of your old URLs. This can help you verify the status codes in bulk.
- Crawl Your List: For large-scale migrations, use a tool like Screaming Frog to crawl your list of old URLs and verify that they all redirect correctly to their intended destination with the correct status code.

Common Issues and Troubleshooting
Even with careful planning, you might encounter issues. Here are a few common problems and how to solve them.
- Problem: Redirect Chains. This happens when URL A redirects to URL B, which then redirects to URL C. Chains slow down your site for users and crawlers and can dilute link equity.
Solution: Use a crawler to identify chains and update your redirect rules to point the original URL directly to the final destination (A -> C). - Problem: Redirect Loops. This occurs when URL A redirects to URL B, and URL B redirects back to URL A, creating an infinite loop that will crash the browser.
Solution: This is almost always a logic error in your redirect map or rules. Carefully check your mapping for any circular references. - Problem: Using a 302 for a Permanent Move. A common mistake is using a temporary redirect for a permanent change.
Solution: This is a simple fix. Change the status code in your redirect rule from 302 to 301. Verify the change is live.
