A redirect is a mechanism that automatically sends users and search engine crawlers from one URL to another. For online store owners, redirects are one of the most important tools in technical SEO.
Incorrectly configured redirects can lead to traffic loss, indexing issues, and lower search engine rankings. Properly implemented redirects, on the other hand, help preserve link equity, prevent 404 errors, and ensure that products and categories remain accessible to both users and search engines.
How Does a Redirect Work?
When a user or a search engine bot requests a page, the server returns an HTTP response. If the page has been moved, renamed, or removed, the server can respond with a redirect status code.
The browser or crawler then automatically loads the new URL specified by the server.
The process looks like this:
Old URL → Server → Redirect Response → New URL
For example:
Old URL:
https://store.com/product123New URL:
https://store.com/catalog/product123Visitors are usually redirected without noticing the transition.
Main Types of Redirects
301 Redirect (Moved Permanently)
A 301 redirect indicates that a page has been permanently moved to a new URL.
This is the most important redirect type for SEO because search engines understand that the old page has permanently changed its location and should transfer most of its ranking signals and link equity to the new page.
When to Use a 301 Redirect
- Changing URL structures
- Updating SEO-friendly URLs
- Migrating to a new domain
- Merging pages
- Replacing discontinued products with alternatives
Example
Old URL:
/smartphone-apple-iphone-13New URL:
/iphone-13A 301 redirect should be configured between these URLs.
302 Redirect (Found / Temporary Redirect)
A 302 redirect indicates a temporary move.
Search engines understand that the original URL may return in the future, so they typically continue indexing the old page.
When to Use a 302 Redirect
- Temporary promotions
- A/B testing
- Website maintenance
- Temporary content replacement
A 302 redirect should not be used for permanent URL changes.
307 Redirect
A 307 redirect is a modern version of a temporary redirect.
It is primarily used by developers because it preserves the original HTTP request method.
From an SEO perspective, it behaves similarly to a 302 redirect.
Meta Refresh Redirect
A Meta Refresh redirect is performed by the browser using HTML rather than by the server.
Example:
<meta http-equiv="refresh" content="5;url=https://store.com">This method is considered outdated and is generally not recommended for SEO purposes.
Why Are Redirects Important for SEO?
Preserving Link Equity
If a page has backlinks and established rankings, deleting it without a redirect can result in the loss of valuable SEO authority.
A properly configured 301 redirect transfers most of that authority to the destination page.
Preventing 404 Errors
A 404 error indicates that a page no longer exists.
A few 404 errors are normal, but large numbers of broken pages can negatively impact user experience and reduce the overall quality of a website.
This is especially important for ecommerce stores with thousands of products.
Maintaining Rankings After URL Changes
When category structures or product URLs change, search engines may treat the new URLs as completely new pages.
Without redirects, rankings and traffic can drop significantly because the SEO value accumulated by the old pages is lost.
Eliminating Duplicate Content
The same page may be accessible through multiple URLs:
http://store.com
https://store.com
https://www.store.com
https://store.comSearch engines may treat these versions as duplicate pages.
Redirects help consolidate all versions into a single canonical URL.
Redirects in Ecommerce
Redirects play a critical role in ecommerce because product catalogs change constantly.
Common scenarios include:
Product Removal
When a product is permanently discontinued, you should:
- Redirect to a similar product.
- Redirect to the most relevant category.
- Return a 410 Gone status if no suitable replacement exists.
Product URL Changes
Whenever a product URL is modified, the old URL should be redirected to the new one using a 301 redirect.
Category Structure Changes
Example:
Old structure:
/catalog/smartphones/apple/New structure:
/apple/smartphones/All old category URLs should redirect to their new equivalents.
Domain Migration
When moving a website to a new domain, every old URL should be redirected to the corresponding new URL using a 301 redirect.
This is one of the most critical stages of any SEO migration project.
Common Redirect Mistakes
Redirect Chains
Bad example:
Page A
↓
Page B
↓
Page CEach additional redirect increases loading time and makes crawling less efficient.
Better approach:
Page A
↓
Page CRedirect Loops
A redirect loop occurs when pages redirect back to one another.
Example:
A → B
B → AThis results in browser errors and inaccessible pages.
Using 302 Instead of 301
This is a common mistake after website redesigns or migrations.
Search engines may continue indexing the old URL, preventing the new page from inheriting its SEO value.
Redirecting Everything to the Homepage
Many websites redirect deleted products to the homepage.
Search engines often consider these redirects irrelevant because the destination page does not match the original content.
Whenever possible, redirect users to the most relevant alternative page.
For large online stores, regular technical audits are essential because catalog updates often create broken links, redirect chains, and indexing issues.
Special attention should be paid when importing products from ERP systems such as 1C, MoySklad, or other inventory management platforms. Changes to identifiers or SEO URLs can easily result in lost organic traffic if redirects are not configured correctly.
Best Practices for Redirect Management
To ensure optimal SEO performance:
- Use 301 redirects for permanent URL changes.
- Avoid redirect chains whenever possible.
- Eliminate redirect loops immediately.
- Redirect deleted products to the most relevant alternative page.
- Regularly audit your website for broken links and redirect issues.
- Test redirects after migrations, redesigns, or catalog updates.
- Monitor indexing and crawl reports in Google Search Console.
Redirects are a fundamental component of technical SEO. They help preserve rankings, maintain link equity, prevent 404 errors, and improve the user experience when website URLs change.
For PrestaShop ecommerce websites, redirects are especially important because product catalogs constantly evolve. Products are removed, categories are reorganized, and SEO-friendly URLs are updated on a regular basis.
A properly configured 301 redirect is not merely a technical adjustment—it is a critical tool for protecting organic traffic, maintaining search engine visibility, and preserving ecommerce revenue.
