301 vs 302 Redirects: Which One Protects Domain Authority?

When you move a domain, migrate a brand, or consolidate two properties, one small technical decision quietly determines whether years of accumulated authority follow you—or evaporate. That decision is the redirect type. Get it right and search engines treat your new address as the rightful heir to the old one's ranking signals. Get it wrong and you're rebuilding from zero.

The choice usually comes down to two status codes: the 301 and the 302. They look nearly identical in a browser—both send a visitor from one URL to another—but to a search engine they mean very different things. Understanding the 301 vs 302 redirect for domain authority question isn't pedantry; it's the difference between protecting a digital asset and accidentally devaluing it.

What a Redirect Actually Tells a Search Engine

A redirect is an HTTP response. When a crawler or browser requests a URL, the server can answer with a status code that says, in effect, "That's not here anymore—go over there instead." The specific code communicates why the resource moved and, critically, whether the move is permanent.

That single distinction—permanent versus temporary—is what governs how link equity, indexing, and ranking signals get treated. Search engines don't guess your intent; they read the status code and act accordingly.

The 301: Moved Permanently

A 301 redirect tells search engines the resource has moved for good. The old URL is retired; the new one is its permanent replacement. In response, engines consolidate the old URL's signals—backlinks, historical trust, indexing priority—onto the destination. Over time, the old URL drops from the index and the new one inherits its standing.

This is the redirect you want whenever authority preservation is the goal: rebranding, moving to a stronger name, switching from HTTP to HTTPS, or merging domains. It is the load-bearing mechanism behind nearly every authority-preserving migration.

The 302: Found (Temporary)

A 302 redirect signals a temporary detour. The message to search engines is: "The original URL is still the real one—keep it indexed—but for now, send visitors here." Because the move is framed as temporary, engines are inclined to keep the original URL indexed and retain ranking signals on it rather than transferring them to the destination.

That behavior is exactly right for genuinely temporary situations—a seasonal landing page, an A/B test, a maintenance detour—and exactly wrong when you're permanently relocating an asset and expect the new address to accumulate authority.

The Core Difference for Domain Authority

Here's the operator's summary, stripped of jargon:

• Use a 301 when you want the destination to inherit the source's authority. Permanent moves, consolidations, rebrands.
• Use a 302 when you want the source to retain its authority while sending traffic elsewhere temporarily.

If your intent is to transfer domain authority from an old name to a new one and you deploy a 302, you've told the engines the opposite of what you meant. They may keep indexing the old URL, split signals, or simply decline to pass the equity you were counting on. The rankings you built don't move—they stall, tethered to a URL you intended to abandon.

The redirect type is a statement of intent. A 301 says "this is the new home." A 302 says "hold my place." When authority is the asset, ambiguity is expensive.

Has Google Softened This Distinction?

It's worth being precise here, because the guidance has evolved. Google has stated that both 301 and 302 redirects can pass PageRank, and that its systems have grown better at inferring intent even when a webmaster picks the "wrong" code. Google's own redirect documentation reflects this more forgiving posture.

But "can pass equity" is not the same as "will pass equity cleanly, quickly, and reliably." Relying on a search engine to correctly guess that your temporary redirect is actually permanent introduces avoidable risk and delay. The 302's default behavior is to keep the original indexed. Why fight the algorithm's baseline assumption when a 301 states your intent unambiguously? For any permanent move, the 301 remains the disciplined choice—and it removes a variable you don't want to gamble on during a migration.

Where Operators Get This Wrong

The failure modes are predictable, and they cluster around three habits.

1. Default server or plugin settings

Many platforms and redirect plugins issue a 302 by default, on the theory that a temporary redirect is "safer" if you change your mind. For a permanent migration, that default silently undercuts your authority transfer. Always confirm the actual status code your server is returning—don't assume.

2. Treating a permanent move as temporary "just in case"

Founders sometimes deploy a 302 during a rebrand because they're not fully committed. Understandable—but if the new domain is the future, hedging with a 302 delays authority consolidation and can leave both URLs competing in the index. Commit, then use a 301.

3. Redirect chains and mismatched codes

A clean redirect points source directly to final destination with a single hop. Chains—A redirects to B redirects to C—dilute signals and slow crawling, and mixing 301s and 302s in the same chain muddies your intent further. We break down the full list of these pitfalls in 7 Common 301 Redirect Mistakes That Kill Domain Authority.

How to Verify You're Using the Right Redirect

Don't trust the interface—verify the response. A few practical checks:

1. Inspect the HTTP response header using a command-line tool or a redirect checker. Confirm you're seeing 301 Moved Permanently, not 302 Found.
2. Test the full path from source URL to final destination and confirm it resolves in one hop with the correct code the whole way.
3. Map every important URL, not just the homepage. Deep pages with valuable backlinks deserve individual, matching redirects to their equivalent destinations.
4. Monitor in Search Console after deployment to confirm the old URLs drop out and the new ones climb.

The HTTP specification (RFC 7231) is the authoritative reference on what each status code formally means, if you want to ground your implementation in the standard.

Putting It Into a Migration Plan

Choosing 301 over 302 is one decision inside a larger sequence. The redirect type sets your intent; execution determines whether authority actually transfers—and how fast. If you're consolidating two properties into one, our step-by-step 301 redirect consolidation playbook walks through the full process. For a single old-to-new move, see how to 301 redirect an old domain to preserve its authority.

Two related questions come up constantly once the redirects are live: how much equity actually moves, and how long it takes. We cover both in how much link equity a 301 redirect passes and how long it takes a 301 redirect to transfer authority. Reading those alongside this piece gives you a complete mental model before you touch a single server configuration.

The Bottom Line

For permanent moves where you want the destination to inherit ranking signals, use a 301. Reserve the 302 for genuinely temporary detours where the original URL should stay indexed. The distinction is simple, but the consequences compound—especially when the authority you're protecting represents years of investment in a name.

That's the lens we bring to every domain in our inventory: a name isn't just an address, it's an asset with a history and a trajectory worth protecting.
