The Watch List is a way to keep track of the campaigns, ad groups or keywords that you want to check back on. So if you mark something on the watch list, you'll get a dashboard of the campaign, ad group, or keyword you are watching when you log into your account on the Dashboard page.

It doesn't do anything to your keyword or ranking. It's just a way to easily keep track of your tests.

I hope that makes sense.
