Google Analytics

Google Analytics (www.google.com/analytics/) is in a class by itself. It offers substantially more functionality than the basic tools above, but is free (as opposed to the more advanced tools listed below).

Unlike tools such as Webalyzer or AWStats, you need to install Google Analytics on your site, which involves pasting a chuck of HTML (provided by Google) into every page. This obviously requires a bit of HTML know-how, but if you know what you're doing, shouldn't require too much effort. Depending on the size of your site and how it's set up, installing the Google Analytics code might take anywhere from a couple of minutes to a few hours. Once the code is added, Google displays your statistics in a custom reporting interface that you can view online.

In addition to the reports offered by tools like Webalizer or AWStats, Google allows you to find out how often visitors come to your site, tracks visitor conversion across a series of pages, compares the behavior of different types of visitors (such as new versus returning, or those from different referring sites), and much more. A selectable date range allows you to analyze any given time period, instead of being limited to a monthly view (as you are with AWStats and Webalizer). Google has a nifty feature that allows you to look at a rendered version of the site and see the percentage of people that clicked each link on a given page. It also offers robust integration to track the performance of any Google AdWords you have purchased.

Because the Google Analytics package is in an indefinite beta stage, some of the experts we consulted with cited occasional problems. Several reported difficulty in getting Google to show up-to-date stats, while others noted a very occasional loss in historic stats for an entire site. Google's customer service supports this product primarily through automated emails, so you may have little recourse if you encounter problems. The method by which this tool monitors traffic results in lower numbers (such as fewer visitors, and fewer page views) than some other methods. Also, keep in mind that Google offers its product for free because it makes money by watching you; by using Analytics, you're agreeing to let Google store your information and use it for aggregate reports.

Nevertheless, Google Analytics is widely used and widely liked. If you're building a new Web site, or have a bit of HTML knowledge, Google is a great free option for surprisingly robust analytics.


More Powerful Analytics Packages

If you find you're running into substantial limitations with Google Analytics, and you're ready to invest in a more predicable and powerful package, there are plenty of available options. The following tools give you substantially more control than any of the above packages; more powerful metrics; much more freedom to perform detailed user segmentation; the ability track detailed patterns; and, oftentimes, sophisticated data charts (such as trees or interactive layouts) that make it easier to track complex sites.

* ClickTracks (www.clicktracks.com). ClickTracks offers solid mid-priced to top-end analytics packages targeted toward non-technical marketing folks. Both an online version (similar to Google Analytics; you add a piece of code to your site and view the reports online) or an installed version (on your Web server) are available. ClickTracks is easy to use and offers many options for on-the-fly analysis of what different types of visitors are viewing on your site. Hosted packages are available at $25 a month, $99 a month, and $239 a month, and installed software ranges from $295 to $10,000 and up. Free trial versions of the hosted options are available on ClickTrack's Web site.
* WebTrends (www.webtrends.com). The well-known WebTrends has a broad user base and offers a variety of hosted and installed packages ranging in price from about $25 to $1,000 a month or more. While it's unclear if the less inexpensive packages offer much more than Google Analytics, their top-level products certainly do, with detailed data-mining features, including segmentation, click paths, conversion reporting, and a number of predictions and alert functionalities (for instance, you can be notified if your site reaches a certain level of traffic). Several of the experts we consulted with report that WebTrends is harder to use than others in this category, especially for non-technical staff. Their customer service, however, is easy to reach and helpful.
* WebSideStory HBX Analytics (www.websidestory.com). WebsideStory's HBX Analytics (formally HitBox) is widely regarded as one of the most powerful and usable hosted analytics solutions, appropriate for complex and highly trafficed Web sites. Like WebTrends, WebSideStory offers a wide range of price points, but is best known for its high-end products.
* Omniture's SiteCatalyst (www.omniture.com). Like HBX Analytics, SiteCatalyst is a powerful hosted analytics package directed at complex and high-traffic sites. It offers powerful segmentation and data-mining features that integrate with the tools's other functions, like email campaigns and site search. Usability is also a strength. SiteCatalyst starts at about $1,000 per month for a package that would support the site volume of most medium- and even large-sized nonprofits.
