After an hour spending time reading about Google Analytics and Google Ads I find out that it is useless for a small blog on WordPress.com. If you want to use Google Analytics to demonstrate certain features for an e-Marketing assignment then WordPress can not help you. To be able to upload a plugin into a blog you will have to upgrade to WordPress.org. Basically you either have to buy a web server for a monthly/annual rate or host your own WordPress blog through its available software.
Once again this is no help to fellow student who wants to use Google Analytics features and the benefits it has for website owners. If a student is not gifted on I.T and does not have a personal made website then they will have to demonstate Google Analytics features with blank figures and diagrams.
May not be a strong demonstration but atleast you are showing how this free Google feature can benefit you or a business.
Hope this helps but for more information Google ‘WordPress.com vs WordPress.org’. This will help you understand the differences between them and which is best suited for your needs.
