Redirect Chain
A redirect chain occurs when a source URL goes through two or more redirects before reaching its final destination — for example, A → B → C → D. It's a classic SEO anti-pattern that burdens both crawlers and users.

Why It Matters
Google will follow up to ~10 redirects, but past 5 hops it increasingly treats them as wasted crawl budget and may drop the page from the index. Ahrefs research suggests ~27% of large-site audits contain URLs with chains of 5+ hops, and these pages lose roughly 15% of their ranking signals (PageRank, backlink authority) at each hop. For users, every hop adds DNS lookups and HTTP round trips, delaying page loads by hundreds of milliseconds.
Chain vs Loop
Chain: A → B → C — linear flow through multiple steps. Slow, but eventually reaches the final URL.
Loop: A → B → A — circular. Crawlers detect infinite loops and abandon crawling; browsers show ERR_TOO_MANY_REDIRECTS. Either way, the URL never gets indexed.
Common Causes
Successive site redesigns: Redirecting /blog → /posts in 2018, then /posts → /articles in 2022, without updating the original source all the way to /articles.
HTTP → HTTPS migration: http://site.com/page → https://site.com/page → https://www.site.com/page when protocol and www redirects are handled separately.
Case and trailing-slash normalization: Stacked rules like /Page → /page → /page/.
Internationalization (i18n): Multi-step flows like language detection → regional path → final page.
How to Fix
Flatten to a direct redirect: Skip intermediate hops and redirect the original URL straight to the final URL. Turn A → B → C → D into A → D, B → D, and C → D.
Consolidate server rules: Bundle protocol, www, case, and slash normalization into a single redirect rule.
Audit regularly: Run Screaming Frog, Ahrefs Site Audit, or Semrush Site Audit monthly to catch new chains.
Update internal links: Replace every reference to old URLs in content, navigation, and sitemaps with the final URL so you don't trigger redirects in the first place.
Keep redirects to one hop: Anything beyond a single hop starts costing you measurable SEO and performance.
