The symptom is specific: important articles are isolated from the rest of the site. Start with the affected item and identify the decision or input that could produce this behavior.
Find the likely cause
New pages were published without navigation or contextual links.
Treat this as an explanation to verify against the actual work. Look at the input, the relevant decision, and the final result together. If the evidence does not support this diagnosis, investigate the mismatch before applying a convenient but unrelated fix.
Make the targeted correction
Add links from relevant established pages and suitable category navigation.
Internal links should help readers discover the next useful page and make relationships between pages understandable.
Check that the repair worked
Reach the article through normal site browsing without its direct URL.
Repeat the check on the final version that the reader or customer will encounter. An approved draft, a preview, and a published result can differ; the acceptance decision should concern the version people actually use.
Prevent the next related failure
A separate issue to watch for is this: aI inserts internal links into unrelated sentences. Place links where the destination answers the reader's next question.
Monitor the useful outcome
Track broken links, isolated pages, and meaningful clicks on contextual links.
Keep a short record of the original symptom, the evidence behind the diagnosis, and the result of the acceptance check. That record makes the solution reusable when the same condition appears again, without assuming that every superficially similar problem has the same cause.
