Hi @joyao ! Thank you for the PR. Look like we are breaking compatibility here. With this change, following configuration will not work anymore:

services:
  googleAnalytics:
    ID: G-MEASUREMENT_ID

Do we want to force user to use analytics configuration from site.Params.analytics.services.google.id ? In that case, we should also provide a way do specify respectDoNotTrack under site.Params.analytics.services.google section.

I think both methods should be supported. I’ll fix it and thanks for your suggestion.

Hi @hossainemruz, under the "{{ with .google }}" condition, my original changes support both project custom settings and original settings as following, and have been tested.

analytics:
  enabled: true
  services:
    # Google Analytics
    google:
      id: G-H4LBG7NDFZ
      respectDoNotTrack: false

services:
  googleAnalytics:
    ID: G-H4LBG7NDFZ
privacy:
  googleAnalytics:
    disable: false
    respectDoNotTrack: true

So I just add the "respectDoNotTrack" part.
