The Numbers Game: Web Site Statistics

When was the last time you looked at your web stats? Many museums and galleries are not aware that they have access to statistics and analytics for their web sites. Every web server maintains statistics in some form or other, and most of them will be running software that changes the arcane log files into meaningful information.

Through web statistics, you can identify high traffic areas of a web site, find out where visitors are coming from, and see how long they spend. But the first thing everyone wants to know: how many people are actually visiting my site?

It is important to note the difference between "hits" and "visitors" (or "sessions"). A "hit" is registered for each and every resource that is accessed on the site; if a page has 4 images on it, 5 "hits" are recorded (1 for the page itself, and 4 for each of the images). Talking about how many "hits" a web site gets in a month is not a very meaningful statistic, what most people are really interested in is how many "visitors" or "sessions" they have recorded.

A "visit" is generally defined as one or more transactions between the Web server and a specific IP Address (every computer on the internet has a unique identifier, or IP address). A session will expire after a certain amount of inactivity (usually 15 minutes). This means that if I visit a web site twice in a week, it will register as two separate visits; if I follow an external link off of a site, but then go back to the site shortly after, it will probably be a continuation of the same visit.

Though usually the most requested statistic, the number of visitors is just one thing you can learn from your web analytics. While "number of visitors" may be a great justifier for the site, or leveraged for funding, many of the other statistics are more functional on a day to day basis, as they give you hints on how to tune your site.

Page views, for example, show you which pages on your site are being requested the most. Is it a page that is buried, but people are still finding it somehow? Is it a page that should have timely information, but that hasn't been updated in weeks (or months)? Maybe it's time to rethink the navigation on the site to make these popular pages easier to find? Usually we assume that our main page is the one that is visited the most, sometimes this isn’t the case.

Your stats can also show how long people are spending on your site. A little advice: don't get discouraged! It may seem that an average session time of one or two minutes is very low, but many visitors are coming to your site to find specific information, not to spend an afternoon. In any given month, the Art Gallery of Greater Victoria website will have only about 15% of its visitors spend more than 2 minutes each and, hey, we're ok with that! We also get a few hundred people a month at the other end of the scale, spending 30 minutes or more on the site.

Finally, some analytical packages such as Livestats (www.deepmetrix.com) allow you to view who is currently on your site, and to track progress through their "click path". If they are having trouble getting from a to b, you can see this in their session, and address it. If many visitors are following the same route (eg. Home page -> current exhibits -> exit) you can think about adding enticements to other parts of your site in a prominent location along their typical route.

Ultimately, statistics can be interesting to browse and can provide a sense of satisfaction when your web site is drawing many visitors, but are at their most valuable when their information is used to repair problems and increase the overall visitor experience.
