https://support.google.com/analytics/answer/1008080It is a string like UA-000000-2. You must set it in the configuration of this plugin, to tell Analytics which account and property to send data to.
Then on every browser that you want to take out of analytics - call your site with appending ?disablega=true to the URL.
To activate it again, append ?disablega=false to your site.
There are also two workflows provided, that you can run to activate or deactivate analytics on this browser.
Note that if your URL already contains a "?" - then append &disablega=false to the URL. For example if you run it in Development or debug mode you might have to write "?debug_mode=true&disablega=true".
Note that it does not prevent loading resources from Google. It's just that the "tagging" calls will not run and no data will be attributed to your Google Analytics account.
You only need to run it once - it's then stored in your browser.
