Web Statistics Definitions
Hits represent the total number of requests made to the server during the given time period (month, day, hour etc..).
Files
represent the total number of hits (requests) that actually resulted in
something being sent back to the user. Not all hits will send data,
such as 404-Not Found requests and requests for pages that are already
in the browsers cache.
Tip: By
looking at the difference between hits and files, you can get a rough
indication of repeat visitors, as the greater the difference between
the two, the more people are requesting pages they already have cached
(have viewed already).
Sites is the number of unique
IP addresses/hostnames that made requests to the server. Care should be
taken when using this metric for anything other than that. Many users
can appear to come from a single site, and they can also appear to come
from many IP addresses so it should be used simply as a rough gauge as
to the number of visitors to your server.
Visits occur when some remote site makes a request for a page
on your server for the first time. As long as the same site keeps
making requests within a given timeout period, they will all be
considered part of the same Visit. If the site makes a request
to your server, and the length of time since the last request is
greater than the specified timeout period (default is 30 minutes), a new Visit is started and counted, and the sequence repeats. Since only pages
will trigger a visit, remotes sites that link to graphic and other non-
page URLs will not be counted in the visit totals, reducing the number
of false visits.
Pages
are those URLs that would be considered the actual page being
requested, and not all of the individual items that make it up (such as
graphics and audio clips). Some people call this metric page views or page impressions, and defaults to any URL that has an extension of .htm, .html or .cgi.
A KByte
(KB) is 1024 bytes (1 Kilobyte). Used to show the amount of data that
was transferred between the server and the remote machine, based on the
data found in the server log.
Common Definitions
A Site is a remote machine that makes requests to your server, and is based on the remote machines IP Address/Hostname.
URL - Uniform Resource Locator. All requests made to a web server need to request something. A URL is that something,
and represents an object somewhere on your server, that is accessible
to the remote user, or results in an error (ie: 404 - Not found). URLs
can be of any type (HTML, Audio, Graphics, etc...).
Referrers
are those URLs that lead a user to your site or caused the browser to
request something from your server. The vast majority of requests are
made from your own URLs, since most HTML pages contain links to other
objects such as graphics files. If one of your HTML pages contains
links to 10 graphic images, then each request for the HTML page will
produce 10 more hits with the referrer specified as the URL of your own
HTML page.
Search Strings
are obtained from examining the referrer string and looking for known
patterns from various search engines. The search engines and the
patterns to look for can be specified by the user within a
configuration file. The default will catch most of the major ones.
Note: Only available if that information is contained in the server logs.
User Agents are a fancy name for browsers. Netscape, Opera, Konqueror, etc.. are all User Agents, and each reports itself in a unique way to your server. Keep in mind however, that many browsers allow the user to change it's reported name, so you might see some obvious fake names in the listing.
Note: Only available if that information is contained in the server logs.
Entry/Exit pages are those pages that were the first requested in a visit (Entry), and the last requested (Exit). These pages are calculated using the Visits logic above. When a visit is first triggered, the requested page is counted as an Entry page, and whatever the last requested URL was, is counted as an Exit page.
Countries are determined based on the top level domain
of the requesting site. This is somewhat questionable however, as there
is no longer strong enforcement of domains as there was in the past. A
.COM domain may reside in the US, or somewhere else. An .IL domain may
actually be in Israel, however it may also be located in the US or
elsewhere. The most common domains seen are .COM (US Commercial), .NET
(Network), .ORG (Non-profit Organization) and .EDU (Educational). A
large percentage may also be shown as Unresolved/Unknown, as a
fairly large percentage of dial-up and other customer access points do
not resolve to a name and are left as an IP address.
Response Codes are defined as part of the HTTP/1.1 protocol (RFC 2068; See Chapter 10). These codes are generated by the web server and indicate the completion status of each request made to it. |
