Omniture Site Catalyst: Props ,eVars and events
Omniture SiteCatalyst is one of the most advanced web analytics solutions available in the market today. SiteCatalyst's advanced reporting capabilities generate over 150,000 report combinations. Traffic reporting lets you analyze all aspects of visitor activity, such as traffic patterns, popular channels, referred technology and finding methods used .
So How does SiteCatalyst collect data?
The SiteCatalyst data collection process is fairly basic. After proper development time, the SiteCatalyst code (or Code to Paste) is placed in the HTML source code on the desired pages of their production web site(s).
Props, eVars and events :
At the heart of SiteCatalyst's data collection methodology are Props, eVars and events. Props and eVars are variables that store data and pass them on to the data collection server, whereas events help in triggering data collection by these variables. Let's look into the variables in a little more detail:
Props and eVars:
Custom Insight Variables, also called props or property variables, are counters that count the number of times each value is sent into SiteCatalyst. They also enable you to correlate custom data with specific traffic-related events. s.prop variables are embedded in the SiteCatalyst code on each page of your website. Through s.prop variables, SiteCatalyst allows you to create custom reports, unique to your organization, industry, and business objectives. For example, if you are an automobile manufacturer you may be interested in seeing "Most Popular Car Model" to complement your "Most Popular Pages" report. You can accomplish this by allocating one of your traffic properties to represent car model and then implement your code to pass in car model on the appropriate pages.
There are endless business questions that can be answered through the Custom Insight Variables, depending on what you are capturing from your website. The following list contains a few common goals and objectives.
§ Understanding user navigation through the web site
§ Understanding internal user search behavior
§ Segmenting traffic by navigation or category
§ Segmenting visitor behavior by demographics
An important thing to note is that Props are non persistent variables. The values that are populated in these variables last only within the context of the particular page.
eVars (or Custom Conversion Insight Variables) are used to identify how well specific attributes or actions contribute to success events on your site. For example, for a media site, eVars may be used to identify how well internal promotions bring visitors to register. When a visitor clicks on the internal promotion, an eVar can be used to store a unique identifier for that promotion. When the same visitor completes registration and a custom success event is fired, the original unique identifier will receive credit for the registration event.
eVars are persistent variables and can be used to store a particular value throughout a session unless over written. They can be used to tie success events to custom variable.
Events are triggers that help in collection of data. For example in case you want to check how many time a certain product has been viewed, you can use an event that is fired each time that product page is viewed. Omniture offers predefined and Custom events which will discussed a later post.
