301 vs 302 Redirects: Preserving Your Backlink Value

You spent real money getting a link pointed at /features/analytics. Six months later your team rebuilds the site, the URL becomes /product/analytics, and now you need to know one thing: does the link you paid for still count? This is where the 301 vs 302 redirects question stops being academic and starts costing money. In the next few minutes you'll learn exactly what each redirect signals to Google, when to use which, and how to move a page that already has purchased backlinks without quietly throwing that value away.

Key takeaways

• Both 301 and 302 redirects now pass full PageRank, so the old "302 kills your link juice" warning is outdated.
• The difference is about canonicalization and intent: a 301 says "this move is permanent, index the new URL," a 302 says "keep the old URL, this is temporary."
• Redirect chains and loops are the real equity killer, not the redirect type. Every extra hop is a chance for crawlers to give up.
• When you move a page that has bought links, redirect the exact old URL straight to the closest matching live page, never the homepage.
• Audit your redirects regularly with Google Search Console and a crawler so you catch broken hops before they waste link equity.

What a 301 and a 302 actually signal to Google

A redirect is a server instruction that says "the thing you asked for lives somewhere else, go here instead." The number is an HTTP status code that tells the browser and the search engine why.

A 301 means "Moved Permanently." It tells Google the old URL is gone for good and the new one should take its place in the index. Over time Google drops the old URL from search results and shows the new one.

A 302 means "Found" (the original spec called it "Moved Temporarily"). It tells Google the move is short-term, so it should keep the original URL indexed and ranking while the detour is in place.

That last part is the practical difference. It is not about how much link equity flows. It is about which URL Google ends up treating as the real one.

The link equity question, settled

For years SEOs repeated that 301s pass "link juice" and 302s leak it. That advice is now wrong. Google's Gary Illyes confirmed that PageRank is not lost through any 30x redirect, and John Mueller has called the idea that 302s don't pass PageRank a myth. Google itself has explained that 301 redirects pass PageRank the same way a link does.

So if equity flows through both, why does the choice still matter? Because Google uses redirects as a canonicalization signal. A long-running 301 tells Google to fold the old URL into the new one and show the new one. A 302 tells Google to keep showing the old one. Pick the wrong signal and you end up with the wrong page ranking, or two competing URLs splitting attention, even though no PageRank technically "disappeared." For a deeper look at how that value moves around your site, see our guide to link equity for SaaS.

When to use a 301 vs a 302

Here is the simple rule: ask whether the move is permanent. If you never plan to bring the old URL back, use a 301. If the old URL will return and you want it to keep ranking in the meantime, use a 302.

Situation	Use	Why
Renamed or restructured a URL for good	301	Permanent move, transfer ranking to the new URL
Merged two blog posts into one	301	Consolidate signals onto the surviving page
Migrated HTTP to HTTPS or changed domain	301	Permanent, you want the new version indexed
Retired a feature page, sending users to the closest match	301	The old page is gone for good
Running an A/B test between two page versions	302	Temporary, keep the original URL indexed
Geo-routing visitors to a regional page	302	Original URL should still rank globally
Page is down for maintenance, sending to a temporary notice	302	You're bringing the real page back
Limited-time promo or seasonal landing page	302	The original returns after the campaign

The mistakes usually go one direction: people reach for a 302 because it feels safer when the move is actually permanent. Google can eventually treat a long-lived 302 like a 301, but you're leaving the canonical decision up to Google's guesswork instead of telling it plainly. For permanent moves, a 301 removes the ambiguity.

Do redirects lose link equity in practice?

In theory, no. In the real world, equity leaks for reasons that have nothing to do with the status code. Three things actually cost you value:

1. Relevance drift. Google passes PageRank when the destination is a reasonable continuation of the original page. If you redirect a retired pricing page to your homepage, Google can treat that as a soft 404 and ignore the equity entirely. The closer the new page matches what the old one was about, the more value survives.

2. Redirect chains. Every extra hop between the link and the final page is friction (more on this below).

3. Time and trust. Even a clean 301 takes time to fully consolidate. Google's documentation notes that 301s are a strong canonicalization signal but not an absolute command, so a redirect that points at an irrelevant or low-quality page won't recover full value no matter how correct the code is.

The takeaway for a link buyer: the redirect type rarely loses you equity. Pointing the link at the wrong page does.

Redirect chains and loops: the quiet equity drain

A redirect chain is when a URL redirects to another URL, which redirects to another, before reaching the live page: /old-page goes to /newer-page, which goes to /final-page. Each hop adds latency, burns crawl budget, and gives Googlebot another point to potentially stop following.

Google has said it will follow up to about five hops before giving up for that crawl, and Ahrefs recommends keeping chains to a single hop. Browsers are even less patient, which hurts the human visitors who clicked your link.

A redirect loop is worse: /a points to /b, and /b points back to /a. Visitors hit an error, crawlers can't index anything, and any link pointing into that loop is dead weight.

These problems compound over years. A SaaS site that has been through two redesigns and a domain change often has links pointing at URLs that redirect three or four times. The fix is to collapse chains: update each redirect so the original URL points directly to the final live URL in a single hop. Broken and dead-end pages cause the same slow bleed, which we cover in broken and orphaned pages that waste link equity.

How to move a page that already has purchased backlinks

This is the scenario that matters most if you've been buying links. You've invested in backlinks pointing at a specific URL, and now that URL has to change. Here's how to keep the value.

1. List the URLs with links before you touch anything. Pull your backlink profile in Ahrefs, Semrush, or Search Console and note every page that has earned or purchased links. These are the URLs you must protect. If you don't have a system for this yet, our backlink tracking guide walks through building one.

2. Map each old URL to its closest live equivalent. The destination should cover the same topic and serve the same intent. A guide redirects to the new guide, a feature page to the new feature page. Avoid the lazy "send everything to the homepage" move, which is the most common way SaaS teams lose equity during a migration.

3. Use a 301, one hop, exact-to-exact. Redirect the precise old URL (including any trailing slash or parameter variant that has links) directly to the final destination. No chains, no intermediate steps.

4. Keep the redirect in place permanently. Don't remove it after a few months. As long as that old URL has even one inbound link, the redirect needs to stay so the equity keeps flowing.

5. Confirm the new page is indexable. Make sure the destination returns a 200 status, isn't blocked by robots.txt, and isn't itself canonicalized to a third URL. A redirect into a noindexed page wastes the link.

6. Re-verify the link target with your supplier if you can. If a link was placed recently and you control the anchor URL through a marketplace order, it's often cleaner to update the live link to point at the new URL directly rather than rely on a redirect at all. A direct link beats a redirected one every time.

Auditing your existing redirects

You can't preserve value you can't see. Run this audit at least quarterly, and always before and after a migration.

Google Search Console. Open the Pages report under Indexing. Look for the "Page with redirect" and "Not found (404)" buckets. A URL that has backlinks but shows up as a 404 is leaking equity right now. The "Soft 404" bucket is a red flag that a redirect is pointing somewhere Google considers irrelevant.

A crawler. Run Screaming Frog or Ahrefs Site Audit and filter by response code. These tools flag redirect chains and loops directly, and most will show the full hop path so you can see exactly where to collapse a chain. Ahrefs' redirect guide is a solid reference for reading those reports.

A header checker. For any single high-value URL, check the raw HTTP response to confirm it returns a real 301 (not a 302, JavaScript redirect, or meta refresh). Server-side 301s are the most reliable, so prefer them.

Cross-reference the broken or chained URLs against your backlink list from earlier. Fix the ones with links first. That's where your money is.

Common redirect mistakes that waste link equity on SaaS sites

• Redirecting everything to the homepage. It's fast, it's tempting, and Google often treats it as a soft 404, dumping the equity. Map to relevant pages instead.
• Leaving 302s on permanent moves. The old URL keeps competing in the index and you never cleanly consolidate signals onto the new page.
• Stacking redirects over multiple redesigns. Each redesign adds a hop. After a few years you're running four-step chains nobody documented.
• Forgetting protocol and www variants. http://, https://, www, and non-www should all resolve to one canonical version in a single hop. Miss one and links pointing at that variant get stranded.
• Removing old redirects too soon. A redirect with even one inbound link is still doing a job. Pulling it 404s that link.
• Redirecting into a noindexed or canonicalized page. The destination has to be the real, indexable page, not another signpost.

Avoiding these is the same discipline as picking quality links in the first place. If you want the broader checklist, our list of SaaS link building mistakes pairs well with this one.

The bottom line

The 301 vs 302 redirects debate isn't really about which one preserves link value, because both pass equity now. It's about telling Google the truth: permanent moves get a 301, temporary ones get a 302, and every redirect points at the closest live page in a single hop. Get that right and your paid backlinks keep working through every redesign and rename.
