First off, I'm not a developer, but a site owner running wordpress. my site has some Amazon affiliate URLS. What is happening is some rogue javascript is running and changing the referral ID's of the HTML code only from a google search specifically (If I load a page directly the HTML doesn't change). Basically I'm trying to figure out how to locate it, I figure that by looking at the html section I can trace what javascript is changing the HTML? With that information maybe I can help find it or pass that on to the hosting company to remove the file.
For example: in the website shows : https://amazon.com/49684095/?tag=properamazontag the javascript runs and changes to: https://amazon.com/49684095/?tag=douchebagscammercode
I hope it makes sense.
I have disabled javascript in the browser and confirm that the HTML code doesn't change, so I know it's a javascript issue.
