Redirect Types 301 302 307: When to Use Each for SEO
Redirect types 301 302 307 explained: learn when to use each redirect, SEO impact, authority transfer, and how to fix chains and loops for rankings in SEO
Why redirect type matters for SEO
A redirect sends users and bots from one URL to another. The redirect type determines how much authority (PageRank) transfers to the destination URL, and what signal Google receives about the permanence of the move. Using the wrong redirect type can mean your destination page receives 0% of the original page's link authority, or that Google treats a permanent move as temporary — continuing to show the old URL in results. This can seriously damage your SEO performance, especially if high-authority pages are involved. In addition, incorrect redirects can create indexing confusion, where search engines waste crawl budget on outdated URLs instead of discovering new or updated pages. Over time, this leads to ranking instability, traffic loss, and weakened site structure. Proper redirect implementation ensures that both users and search engines are always guided to the correct version of a page without friction. It also helps maintain a clean website architecture, improves user experience by avoiding broken or irrelevant pages, and preserves long-term domain authority during site migrations, URL changes, or content restructuring.
301 redirects pass approximately 90–99% of the original page's link authority to the destination. 302 redirects pass little to no authority because Google treats the original URL as still valid. If you are moving a page permanently and want to preserve its rankings, always use a 301.
The 3 redirect types you need to know
Redirect chains — the silent authority killer
A redirect chain occurs when multiple redirects happen in sequence before the user or bot reaches the final destination: URL A → URL B → URL C → final page. Each hop in the chain loses a small amount of PageRank (estimated 10–15% per hop) and increases page load time. A chain of three redirects might deliver only 70–80% of the original page's authority to the final destination, compared to 90–99% from a single direct redirect.
Redirect chains accumulate naturally over time as sites are restructured, pages are moved, and domains are consolidated. A URL migrated three times over five years may have a chain of four or five hops connecting the oldest URL to the current one. Regular auditing prevents chains from growing.
The fix is always the same: update all redirects in the chain so they point directly to the final destination URL, bypassing all intermediate hops. A four-hop chain (A→B→C→D→Final) becomes four direct redirects (A→Final, B→Final, C→Final, D→Final).
Redirect loops — and how to identify them
A redirect loop occurs when URL A redirects to URL B, which redirects back to URL A (or through a longer chain that eventually returns to a URL already in the sequence). Loops return a "Too many redirects" error in browsers and cause Googlebot to abandon crawling the URL entirely. Common causes: incorrect .htaccess redirect rules, poorly configured SSL/HTTPS setup, www/non-www redirect conflicts, and CMS plugin conflicts.
RankAudit's redirect audit report identifies both chains and loops in your site's redirect structure. Fix loops by identifying which redirect in the sequence is incorrect — usually one rule that should not apply to the destination URL of another rule.
Common redirect scenarios and the right approach
| Scenario | Redirect type | Notes |
|---|---|---|
| Page permanently moved to new URL | 301 | Update all internal links to point directly to new URL; do not rely on redirect forever |
| Page deleted — good replacement exists | 301 to best relevant page | Do not redirect to homepage — find the closest relevant alternative page |
| Page deleted — no good replacement | 410 Gone (preferred) or 404 | 410 tells Google the page is intentionally gone; 404 signals it was accidentally removed |
| HTTP → HTTPS migration | 301 | Redirect all http:// URLs to their https:// equivalents; update canonical tags simultaneously |
| www → non-www (or vice versa) | 301 | Pick one version and redirect all traffic from the other permanently |
| A/B test landing page | 302 | Keep original URL indexed during test; switch to 301 after test concludes if change is permanent |
| Site migration to new domain | 301 | Every old URL must redirect to its equivalent new URL; avoid redirecting all old URLs to the new homepage |
