Affiliate content ages, and inaccurate content converts badly and damages trust.
WHAT CHANGES
Prices, particularly renewal prices Plan limits and what is included Control panel interfaces and screenshots Features added or removed Your own experience, if you move or your usage changes
WHY IT MATTERS
A reader following your tutorial who finds the interface does not match, or the price is different, stops trusting the rest of it and frequently does not order.
A REVIEW ROUTINE
Once or twice a year, go through your affiliate content and check:
Prices quoted, against current pricing Screenshots, against the current interface Feature claims, against what is actually offered Links, which break silently Anything you said about your own use that is no longer true
WHAT TO DO WITH OLD CONTENT
Update it rather than leaving it. An article that ranks well is worth maintaining; rewriting the outdated parts preserves its position and its conversions.
If something is no longer accurate and you do not intend to update it, remove the recommendation rather than leaving a misleading one.
