Broken internal link
A broken internal link is a link from one page on a site to another same-site URL that fails to reach its intended usable destination.
What it means
The target may return 404 or 5xx, enter a loop, point to a malformed address or land on an unrelated replacement. A link that redirects is not necessarily broken, although updating controllable links to the final Canonical URL can remove latency and ambiguity.
Why it matters
Broken links interrupt user tasks, waste crawl requests and disconnect pages from the site's navigational context. They can also reveal incomplete migrations, deleted assets or case and trailing-slash rules that affect more than one template.
Example
A guide links to `/setup-old/`, which now returns 404 after a documentation migration. If `/setup/` is the verified equivalent, update the source link directly; if no replacement exists, remove or rewrite the surrounding instruction instead of redirecting to the homepage.
Common mistakes
Do not classify every 301 as broken, replace targets by string similarity alone or ignore links inside reusable templates. Avoid creating an unrelated redirect merely to make a crawler report green.
How AYSA handles this
Signals reviewed
Source URL and anchor, target response, redirect path, final canonical, template occurrence count
Problem AYSA can identify
AYSA can crawl internal hrefs and group broken or indirect targets by source template and final outcome.
Recommendation prepared
The proposal identifies the verified equivalent destination or recommends changing the source copy when no safe replacement exists.
Approval preview
The user reviews each source, anchor, current response, proposed target and number of affected occurrences.
Execution
AYSA can update approved links in supported WordPress content; shared theme code and application components may require developer deployment.
Verification
AYSA recrawls every changed source and confirms the link reaches the approved final 200 URL without unintended hops.
Limits
AYSA does not infer semantic equivalence from URL similarity alone and cannot repair destinations owned by third parties.

Quick answers
Frequently asked questions
Is an internal link that returns a 301 automatically broken?
No. It may still reach a valid destination, but updating the source to the final canonical URL can remove an avoidable hop and reduce future failure risk.
