Why redirect chains kill SEO and site speed
A redirect is any HTTP response that sends the browser somewhere else — usually a 301 (permanent) or 302 (temporary). Every redirect adds a round trip to the network: DNS lookup, TCP handshake, TLS negotiation, HTTP request. On a fast connection that's 100–300ms per hop. On mobile, it can be 500ms or more. A three-redirect chain from http://example.com → https://example.com → https://www.example.com → https://www.example.com/en/ can add 1.5 seconds before your page starts loading.
Google also loses some ranking signal at each hop. A single 301 passes ~99% of link equity; three chained 301s pass noticeably less. And after five hops, most search engines just give up and don't index the destination at all.
