Link Redirect

A link redirect is a server instruction that sends a visitor from one URL to another automatically. When someone clicks a redirected link, the server returns an HTTP status code (such as 301 or 302) and the visitor’s browser loads a different URL instead of the original. Redirects are used to handle moved pages, consolidate duplicate URLs, shorten long links, and route users to region or device-specific content.

How Link Redirects Work

A link redirect happens at the HTTP level before the page even loads. The exchange takes three steps.

1. The browser sends a request to the original URL like https://example.com/old-page.
2. The server responds with a redirect status code (such as 301 Moved Permanently) and a Location header pointing to the new URL.
3. The browser follows the Location header and requests the new URL automatically.

The visitor sees the destination URL in the address bar, not the original. The whole process usually completes in a few hundred milliseconds. Search engine crawlers follow the same logic, so a redirect tells Google where a page now lives.

A redirect response looks like this in raw HTTP:

HTTP/1.1 301 Moved Permanently
Location: https://example.com/new-page

Why Link Redirects Matter

Redirects keep traffic and SEO signals intact when URLs change. Without them, every link to a moved page returns a 404 error, and the page’s ranking, backlinks, and bookmarks all break.

Google’s John Mueller has stated that 301 redirects pass “the vast majority” of ranking signals to the destination URL. That makes redirects the standard tool for site migrations, HTTPS upgrades, domain changes, and URL restructures.

Redirects also serve marketing use cases. Branded short links use a 301 redirect under the hood: a clean URL like linkutm.co/launch resolves to a long campaign URL with UTM parameters attached. The visitor sees the short link, the analytics platform sees the full tagged URL.

Types of Link Redirects

Redirects fall into two broad groups: server-side (HTTP status codes) and client-side (HTML or JavaScript). Server-side redirects are stronger for SEO and performance.

Server-Side Redirects

• 301 Moved Permanently. The page has moved for good. Browsers and search engines update their records. Use this for site migrations and removed pages.
• 302 Found (Moved Temporarily). The redirect is temporary. The original URL keeps its ranking. Use this for A/B tests, geo-targeting, or maintenance pages.
• 307 Temporary Redirect. Same intent as 302 but stricter. The HTTP method (GET, POST) cannot change between the original and destination URL.
• 308 Permanent Redirect. Same intent as 301 but preserves the HTTP method. Less common but useful for API endpoints.
• 303 See Other. Forces a GET request on the destination, regardless of the original method. Used after form submissions to prevent duplicate POSTs.

Client-Side Redirects

• Meta refresh redirect. An HTML tag (<meta http-equiv="refresh" content="0;url=...">) that redirects after a delay. Slow and weak for SEO.
• JavaScript redirect. Uses window.location to send the visitor elsewhere. Works only if JavaScript runs.

For full guidance on each type, see linkutm’s URL redirect types guide.

When to Use Each Redirect

The right code depends on whether the move is permanent and whether the HTTP method matters.

Situation	Recommended redirect
Permanent URL change	301
Site migration to new domain	301
HTTP to HTTPS upgrade	301
A/B test on a page	302
Temporary maintenance redirect	302 or 307
Region-specific routing	302
Form submission post-process	303
API endpoint move (preserve method)	308

Using the wrong code costs SEO equity. A 302 used for a permanent move tells Google to keep the original URL indexed, splitting ranking signals between two pages.

Common Link Redirect Issues

Most redirect problems fall into a small set of recurring patterns. Each one slows the page and weakens SEO.

• Redirect chains. URL A redirects to B, which redirects to C. Google’s John Mueller recommends keeping chains under five hops, but ideally chains should be flattened to a single redirect.
• Redirect loops. A redirects to B, which redirects back to A. The browser fails with ERR_TOO_MANY_REDIRECTS and the page never loads.
• Mixed-case mismatches. A 301 from /Page to /page works, but if internal links still point to /Page, every visit triggers an extra redirect.
• Wrong status code for the use case. 302 for a permanent move splits SEO equity between the old and new URL.
• Missing redirects after migration. Old URLs return 404 instead of redirecting, breaking inbound links from search and external sites.

linkutm’s redirect checker traces the full chain behind any URL and flags loops or unnecessary hops before they affect users.

Frequently Asked Questions

What is a link redirect in simple terms?

A link redirect is an automatic forward from one URL to another. When a visitor opens the original link, the server tells the browser to load a different URL instead. The visitor lands on the new page without doing anything extra.

How does a URL redirect work?

The server returns an HTTP status code (such as 301 or 302) and a Location header pointing to the new URL. The browser reads the header and requests the new URL automatically. The whole exchange happens in a fraction of a second before the page renders.

What is the difference between a 301 and 302 redirect?

A 301 redirect is permanent and a 302 is temporary. A 301 tells search engines to update their index and pass ranking signals to the new URL. A 302 tells them to keep the original URL indexed because the redirect will be removed later.

Do link redirects affect SEO?

Yes. A 301 redirect passes most ranking signals to the destination URL, while a 302 keeps them on the original. Long redirect chains slow page load and dilute crawl efficiency. Use the right status code and keep redirects to a single hop.

How do I check if a URL has a redirect?

Use a redirect checker tool or open the browser developer tools network tab and look at the response headers. A redirect shows a 3xx status code and a Location header. The full chain (if any) is visible in the network log.

To audit your existing links for chains, loops, or wrong status codes, run them through linkutm’s redirect checker.
