Implementing rollup reporting in Google Analytics

If your company run several websites, sub-domains and/or mobile apps to promote various brands/regional business units and you want to understand the overall performance of your company and also compare the performance of individual brands/ business units to each other then you need to set up rollup reporting in your Google Analytics account.

Rollup reporting is simply the reporting of data in aggregated form from multiple digital properties (websites, mobile apps).

For example if you have setup separate websites for each country (abc.com, abc.co.uk, abc.com.au,abc.in etc) then through rollup reporting you can aggregate all of your websites data in one view and see aggregated global performance metrics and/or compare the performance of various country specific websites to each other.
