Skimlinks respects all pre-existing affiliate links on a page, and we do not overwrite any links that already have affiliate tracking.
Our script will only re-write unadulterated merchant links without affiliate tags where an affiliate link is available.
Please note that some links may still show as re-redirecting through Skimlinks (go.redirectingat) however this is only for tracking purposes. These links will come through to us as 'Unaffiliated' and will appear in the "Unaffiliated Clicks" section in The Hub.
If you would like us to rewrite your affiliated Amazon links, you can use our special Amazon Overwrite tool. This feature can be switched on from within the Tools menu.
