Append "udm=14" to your Google searches to make this stuff go away (for now, until Google removes it).

You can add a custom search engine to your browser with something like:

  https://www.google.com/search?q=%s&udm=14

Sometimes that will glitch out on Chromium browsers. If so, try this variant:

  {google:baseURL}search?q=%s&udm=14
