The main principle behind the Reports Constructor is that in any report you can choose one of the result rows and "go deeper”, leaving the current choice as a limit for the next "deeper" report. For example, you choose report “by sites”, then click on one of the sites, choose report “by search engines” and see what search engines have brought visitors to this particular site. You can go deeper until the list of reports available is over.
You can save any report that you've created in the Reports Constructor. After saving it will be available in the section “All reports”. And the most important is that every saved report automatically becomes a part of the Caching and Archiving functionalities of the tracker.
The Reports Constructor filter allows you to limit the reports by a certain date or time period. A number of built-in time periods is always available to you and you can always create your own time periods.
In many reports you will find summarized data at the bottom.
1. Column sums + Minimum, Average and Maximum values.
These data is only displayed when the number of the rows in the report does not exceed the limit set by you in the filter (by default it is 20). Otherwise it will be impossible to calculate the sum of columns.
The sum is based on the displayed rows in the report. For all the columns where the number of unique visitors is displayed, the sum value can potentially be not equal to the actual sum of the unique visitors. For example, if you are viewing a “site report”, and a visitor has visited not only one but several of the sites, he/she will be counted in several report rows. The number of unique visitors will be correct for each particular row, while the sum of the values in the rows will be incorrect because one and the same visitor will be counted several times.
The very bottom line reflects the real sum that is calculated in the database. This sum counts one and the same visitor only once, therefore the values can be less than in column sums (but they are correct).
Since the calculation of this value requires a separate query to the database and this query will take as long (or even longer) as the full report, we decided to make it optional.
However, in the cached reports this data is available immediately.
Only a few report columns need to be explained.
1. Hits (same as "Page views”)
It is the number of page views done by all the visitors that satisfy the conditions of the current report and particular row in the report. Note that it is not the number of different pages, but the total number of page views.
2. Unique visitors (in the columns of sales and actions)
These columns reflect the number of unique visitors who have made actions or sales, and not the number of unique actions or unique sales.
These columns display the relation of unique visitors who have made actions or sales to the total number of unique visitors.
