Introduction
When you move or delete pages on your Squarespace site, you risk creating broken links that frustrate visitors and harm your search rankings. 301 redirects solve this problem by automatically sending visitors and search engines from old URLs to new ones.
This chapter covers the fundamental theory behind 301 redirects and why they're crucial for maintaining a healthy Squarespace website. You'll learn how these redirects preserve your SEO efforts and keep your site navigation smooth for users.
Lessons
What is a 301 Redirect?
A 301 redirect is a permanent instruction that automatically sends visitors from one URL to another. When someone clicks a link or types in an old web address, the redirect instantly takes them to the new location without any action on their part.
Here's what makes 301 redirects special:
- They transfer link equity (ranking power) from the old URL to the new one
- Search engines understand the move is permanent and update their records
- Visitors never see error pages or broken links
Think of it like forwarding mail when you move house. The post office automatically sends letters from your old address to your new one, so nothing gets lost.
Why 301 Redirects Matter for Your Site
301 redirects serve two critical purposes that directly impact your site's success.
For search engines:
- They preserve your search rankings by transferring SEO value to the new URL
- They prevent search engines from indexing broken or outdated pages
- They help maintain your site's authority and credibility
For your visitors:
- They eliminate the frustration of hitting dead links
- They ensure smooth navigation even when content has moved
- They maintain a professional user experience
This is the bit most people miss: without proper redirects, you lose months or years of SEO work every time you restructure your site.
When to Use 301 Redirects
You'll need 301 redirects in several common scenarios:
Page deletions: When removing content permanently, redirect to the most relevant existing page rather than showing a 404 error.
URL changes: If you rename a page or change its slug, redirect the old URL to maintain any existing links and bookmarks.
Site restructuring: When reorganising your site structure, redirect old category pages to new ones.
Content consolidation: When merging multiple pages into one, redirect the old pages to the new combined page.
Domain changes: If moving to a new domain, redirect all old URLs to their new equivalents.
The key is being proactive. Set up redirects before making changes, not after you discover broken links.
How 301 Redirects Work on Squarespace
Squarespace handles 301 redirects through its URL Mappings feature, which you'll find in your site settings. When you add a redirect, Squarespace automatically implements the proper server-level redirect code.
The process happens instantly:
- A visitor requests the old URL
- Squarespace checks for any matching redirects
- If found, it immediately sends them to the new URL
- The visitor sees the new page without any delay
Squarespace supports both individual page redirects and pattern-based redirects for multiple pages, giving you flexibility in how you manage your site's URL structure.
Practice
Create a list of any pages you've deleted or moved on your current site. Check whether each old URL still receives traffic by typing it into your browser. If you find any dead links, note down what the most appropriate redirect destination would be for each one.
FAQs
What happens if I don't set up redirects?
Visitors will see 404 error pages, and search engines will remove the old pages from their index. You'll lose any SEO value those pages had built up.
Can I redirect to external websites?
Yes, you can redirect Squarespace URLs to external sites, but use this sparingly as it sends visitors away from your site.
How many redirects can I set up?
Squarespace doesn't publish a specific limit, but keep redirects organised and remove any that are no longer needed.
Do redirects slow down my site?
Properly configured 301 redirects have minimal impact on loading speed. However, avoid redirect chains where one redirect leads to another.
Can I redirect an entire section of my site?
Yes, you can use pattern-based redirects to redirect multiple pages at once, such as redirecting all blog posts from one category to another.
