Difference Between CNStats PRO and CNStats STD

All calculations are performed via visitors' access to the web-site pages.

Advantages:

• The system characteristics and abilities are sufficient for most projects.
• Easy installation.
• Additional software (crontab) is not required.

Disadvantages:

• It is impossible to guarantee correct script termination upon access via the browser, since the web-server can abort its execution at any moment. The longer the script execution time is, the greater the probability of such occurrence will be.

  Thus, there appears the possibility of loosing certain days from the statistics at a high server load, caused by incorrect counter reset at midnight (the lost days can be restored via the menu). Therefore, complex reports (for example, reports sent via e-mail) cannot be implemented at CNStats STD.

  (You can solve this issue at some servers with the help of PHP-functions set_time_limit() and ignore_user_abort(), but almost all providers forbid their usage).

• Due to irregular calling of additional function, the number of SQL calls, executed at the moment of counter loading, is greater than in CNStats PRO.

Complicated calculations are performed on the server at the specified time, regardless of visitors' access.

Advantages:

• The server generates reports at the specified time (at the moment of minimal load). It allows you to calculate characteristics modification dynamics (for example, changing of the number of jumps from a certain site, page, or search system).
• Executing complicated calculations on the schedule and reducing calls to the database increase the system efficiency and reliability.
• There is no issue with "lost days" in the statistics. The counter is reset at midnight correctly, regardless of the server settings and workload.
• The geographic module CNGeoip is included into the distribution kit.

Disadvantages:

• Additional requirements to the server: crontab access and possibility to execute perl scripts with DBI module. However, most hosting-providers give these opportunities at common tariff plans.
• Complicated installation: you should set up the rights for Perl-scripts correctly and then add them to crontab.

CNStats STD does not have this block.

This block of reports is intended for analysis of advertising campaigns effectiveness performed via Google.AdWords.

The reports display the log of jumps with possibility to display the advertisements design and format as well as rating of advertising sites (by Google.AdSense pages, sites, users).

This report displays changes in the number of jumps from the search engines.

The report requires regular manual generation.

The report does not require regular manual generation.

The report displays the list of referring pages for a particular period of time.

In addition to the list of referring pages for a particular period of time, the report also displays the dynamics in changes of the number of jumps from one or several pages for the last 90 days.

The report displays the list of referring servers for a certain period of time.

In addition to the list of referring servers for a certain period of time, the report also displays the dynamics in changes of the number of jumps from one or several servers for the last 90 days.

This report displays summary inforamtion on the effectivness of the advertising campaigns such as the number of clicks, the number of actions, cost per click, cost per action, average and total values.

Besides, the report also demonstrates the changes in the number of jumps from different advertising sites.
