Redirect chains

A URL that reaches its destination through two or more redirects costs every visitor and every crawler extra round trips.

Do this: Point the first URL straight at the final destination. Every extra hop is a full request: DNS, connection, TLS and response.
PassNo URL redirects more than once.
MediumURLs reach their destination through two or more redirects.

The fix, in one snippet

Example to adapt Collapse the chain into one rule
return 301 https://www.example.com$request_uri;

Illustrative values. Change the paths, hostnames and options to match your own site before using it.

The sections below explain what is tested, why it matters and the alternatives.

What we test

The crawler follows redirects one hop at a time and records the full chain for each URL: every intermediate address and its status code. This check reports any URL that needed two or more hops to resolve.

A single redirect is normal and is not reported. Two or more is a chain, and the evidence shows each step so the shortcut is obvious.

Why it matters

Each hop is a full request: DNS, connection, TLS handshake, response. On a mobile connection a two-hop chain can add half a second before the first byte of real content arrives.

Search engines follow a limited number of hops, and although the modern limit is generous, signals weaken along a chain and Google's own guidance is to keep chains to one hop. Long chains also make debugging harder: when something breaks in the middle, the symptom appears on a URL that has nothing obviously wrong with it.

Chains accumulate. A site moves to HTTPS, then to a new domain, then restructures its URLs, and each migration adds a hop to rules nobody revisits.

How to fix it

Collapse each chain so the first URL redirects straight to the final destination. Rewrite the rules rather than adding another one on top:

# before: three hops
http://example.com/old  ->  https://example.com/old
                        ->  https://www.example.com/old
                        ->  https://www.example.com/new

# after: one hop, and canonical host and scheme applied together
return 301 https://www.example.com/new;

Put the scheme and host canonicalisation in a single rule at the edge, and keep path-level redirects in one table that is reviewed at each migration. Then update the internal links that still point at the old URL: a redirect is a safety net, not a substitute for a correct link.

Where this fits

Redirect chains is check 7 of 10 that the seo & site health audit runs under indexing and crawlability, ordered the way they are worth fixing. That ordering is the point: Fixing this one while the check above it still fails buys less than it looks like.

Fix this one first

Above it in the same category sits Linked pages blocked by robots.txt (medium), where a page you link to internally but disallow in robots.txt sends contradictory signals and wastes the link. An attacker who has that does not need this, so it is the better use of the same hour.

What fixing this still leaves open

Redirect chains closes one route in. Immediately below it: Sitemap URLs are live and indexable, where every URL in a sitemap is a claim that the page exists and should be indexed; XML sitemap published and declared, where an XML sitemap lists the URLs you want crawled and when they last changed; robots.txt present and usable, where robots.txt is the first file a crawler asks for.

Found in the same scan

The seo & site health audit reports this alongside checks from other categories that are at least as serious, including Broken internal links, where an internal link that returns an error is a dead end for the reader and a wasted request for the crawler, and Duplicate body content, where two pages with identical body text are one page at two addresses, and search engines will pick one of them for you. A single run of seo & site health audit answers all of them at once.
