The link that quietly disappears

The link that quietly disappears

Grouping this week's threads on permanence, because it's the most under-tracked failure.

— A Reddit thread: links removed 60–90 days after purchase once the seller assumed the buyer stopped checking.
— An agency post notes some hosts swap your dofollow to nofollow silently, which is harder to catch than full removal.
— A forum reply shares a fix: set up automated monitoring on every placed URL and screenshot the live link plus its attribute at delivery.

Editor's note: 'permanent' in a listing is a promise, not a guarantee. Without monitoring you're paying for links that may not exist by the time they'd start mattering. Track attribute changes, not just presence.

Pick of the week: the thread comparing link-monitoring tools people actually run on edits.
