Data Processing

The data processing in UA is visitors based instead of visit (sessions based). This is not the case with Google Analytics, Classic and Google Urchin. Apparently, Universal Analytics is visitors centric rather than visit centric.

Data integration

Data integration across multiple channels is not possible in Google Urchin and Google Classic, but you can integrate data across multiple devices and platforms through Google Universal Analytics.

Dimensions & Metrics

Google Urchin and Google Classic does not allow you to define your own dimensions and metrics, but you can create and use your own dimensions and metrics to collect types of data in Universal Analytics. In Universal Analytics, through custom dimensions, you can import additional data into your analytics account.

Cookies

Google Analytics and Google Urchin can use up to 7 cookies (_utma, _utmb, _utmc, _utmt, _utmz, _utmx, _utmy) to collect visitor’s usage data. Now _utmc cookie is not used in ga.js anymore but is still set on the user’s hard disc for interoperability with urchin.js and _utmc cookie expires as soon as you close the browser window. Universal Analytics can use only 2 cookies (_ga and_gat).

Variables

Google Urchin and Google Analytics use custom variables instead of custom dimensions as custom dimensions are not available in Google Analytics. Universal Analytics uses custom dimensions instead of custom variables though custom variables are still available in Universal Analytics.

Technical knowledge

To use all features of Universal Analytics, you require good technical knowledge as compared to Google Classic and Google Urchin.

If you don’t have good technical knowledge, you will have a hard time using custom dimensions, custom metrics, and integrating data across multiple device and platforms.

In Universal Analytics, from e-commerce tracking, event tracking to cross domain tracking is implemented differently.

User Interface

The user interface of reports for Universal Analytics, Google Urchin and Google Analytics look the same. The difference is only how to collect, integrate, and process the data and once you start using custom dimensions and custom metrics, Universal Analytics reports start looking different from the Google Analytics, and Google Urchin report.

JavaScript Library

  • Google Urchin uses a urchin.js JavaScript library.
  • Google Analytics uses a ga.js JavaScript library.
  • Universal Analytics uses an analytics.js JavaScript library.
  • Google Tag Manger uses a gtm.js JavaScript library.

E-commerce tracking

Universal Analytics provide advance e-commerce tracking called enhance e-commerce. E-commerce tracking is not available in Google Analytics and Google Urchin.

Differences between Analytics Tags and Tag Manager

Google Analytics tags (Urchin, Classic, and Universal) is basically for generating the reports and statistics about your website. A report provides statistical data like how many people visited your website, what are the sources and medium, what browser and devices they used, which pages are popular, etc. This can happen once you put the tag is the JavaScript code on all of your website pages. Once a user comes to your site, that script runs on the page loading time and let the Google Analytics servers know that they are visiting the site right now. In case you want to track how many people visited a specific feature and maybe you want to group a set of pages together or count some similar but different URLs as being the same page. Now you need unique tags for all these different features and groups of pages, so that Google can identify which feature or type of page got used or visited. Now it's complicated! You have multiple tags, and you only want the tags to "fire" sometimes (e.g. don't fire unless they click this button or use this feature.) Google Tag Manager makes it easier to deal with this chaos of tags by giving you chance to define rules for when your tags should fire.
It additionally lets you test your tags to ensure they go off when you load the correct page or click a certain button. This is done by putting the Tag Manager's code on your website instead of the actual tags, the tag manager outputs the tags for you. Google Tag Manager gives you another advantage that you can change your tags and the way they work without changing the source code of your website instead you just change it from the Google Tag Manager website, and it will give a different code on your pages dynamically when they're loaded in the visitor's browser. So, we can pass information from one data source like a website to another data source like Analytics through Google Tag Manager.

Conclusion:

Universal Analytics is the latest Google analytics tracking code used to track your website. This comes with features like User-ID to collect engagement data on various platforms, collect data from any digital device using analytics SDKs, features like custom dimensions and metrics, enhanced e-commerce tracking and enhanced configuration options.
