Do 301 Redirects Pass Link Juice? What Google Says

Yes, 301 redirects pass link juice. Google's own documentation and public statements confirm that a permanent redirect carries PageRank from the old URL to the new one. In 2016, Google's Gary Illyes said there is no dilution at all with 301, 302, or other 3xx redirects. The juice survives the move, as long as the redirect is set up correctly.

What Google has actually said about 301 redirects

Google's documentation on redirects describes 301s as the standard way to tell Google a page has permanently moved. Google's Gary Illyes went further in 2016, stating that any 30x redirect — not just 301 — passes full PageRank with no dilution. Before that, many SEOs believed each redirect hop lost a small amount of value, similar to how a link used to lose a fraction of its juice. Google closed that debate directly, as reported by Search Engine Land.

This matters for anyone doing link juice work. It means you do not need to panic about ranking loss every time you redirect a page. The bigger risks come from how the redirect is built, not the redirect type itself.

Redirect chains and loops still cause problems

No PageRank dilution does not mean chains are harmless. A chain happens when URL A redirects to B, which redirects to C, and so on. Google's John Mueller has recommended keeping chains under five hops for URLs that get crawled often, according to Search Engine Journal. Long chains slow down crawling, waste crawl budget on large sites, and can simply fail if a browser or crawler gives up before reaching the final URL.

A redirect loop is worse. That happens when A redirects to B, and B redirects back to A. Browsers and crawlers detect the loop and stop, so the page never loads. Any juice pointed at that URL goes nowhere.

HTTP to HTTPS moves and domain migrations

Moving from HTTP to HTTPS, or moving an entire site to a new domain, relies on the same rule. A clean, one-to-one 301 redirect from every old URL to its matching new URL passes the link juice built up over years. The mistake most sites make is redirecting everything to the homepage instead of the matching page. That breaks the topical match Google uses to judge relevance, and it wastes most of the value in the old backlinks.

Before a migration, export your full URL list and your backlink list. Map every old URL to its closest new equivalent. Redirect page to page wherever possible, not page to homepage.

Why irrelevant redirects can become soft 404s

If you redirect an old page to a page with a completely different topic, Google may treat the result as a soft 404. That means Google decides the redirect does not actually satisfy the original URL's intent, and it may stop counting the redirect as a real page move. Google's guidance on HTTP status codes explains how mismatched redirects get flagged this way.

The fix is simple: only redirect to a genuinely related page. If no related page exists, consider a 410 (gone) instead of forcing a bad redirect. A wasted redirect is no better than a broken link for internal link juice or external link value.

Practical tips for keeping the juice flowing

• Redirect page to page, not page to homepage, whenever a close match exists.
• Keep chains to one hop. Update old redirects to point straight to the final URL instead of stacking new ones on top.
• Check your redirects with a crawler after any migration, not just once at launch.
• Never redirect to an unrelated page just to preserve a backlink count.
• If you buy or earn new links, check that the target URL is live and not mid-redirect before publishing.

This is the same care we apply when placing links for clients. A link is only as good as the page it lands on, before and after any redirect.
