The Link Checker provided in Associates Central does not work correctly with links that are copied from Associate Central or the Site Stripe. It is designed only to check the tagging for a URL linking to Amazon.com. This tool is intended primarily for people constructing or modifying their own Associate links to Amazon.com.
Using the Build Links/Widgets tools when signed in to Associate Central will automatically include the Associate ID or Tracking ID that you have selected. The Link Checker does not check the tagging for our served links such as Omakase, Recommended Product Links or other Widgets.
