A plain-language explanation
External linking is placing links from one domain to resources located in another domain.
Where it helps in practice
An external link can support a source or extend a topic, but it should lead to a current and trustworthy destination.
The decision before implementation
Assess purpose, commercial relationship, opening security and future URL change before publishing.
A common mistake
A common mistake is treating External linking as a goal or proof of success on its own. It becomes meaningful only in the context of a user, a specific page and the decision it supports.
How to verify the result
Recheck failures, redirects, domain ownership and whether the destination still supports the surrounding claim.
A business takeaway
External linking should simplify work or improve the audience experience. At PAR HOUSE Agency we record the expected outcome and baseline before choosing configuration and optimisation scope.
