Who Should Use This Document
This document provides a comparison of SmarterTools’ SmarterStats Web log analytics
and
SEO
software and the Google Analytics website statistics service. The comparison is
from the end user’s point of view.
Overview
Regardless of whether a website is designed for a business or individual, it is
important to collect and evaluate the site’s analytics. At a very basic level, this
involves tracking information about unique visits, page views, bounce rates and
conversion rates. Analyzing this data will help you predict visitor behavior and
modify your website design and/or marketing campaigns for improved success.
Methods for Gathering Website Analytics
The Web Analytics Association defines Web analytics as “the measurement, collection,
analysis and reporting of Internet data for the purposes of understanding and optimizing
Web usage.” There are two main methods for collecting website analytics: log file
analysis and script-based analysis.
Every time someone visits a website, the Web server records information about every
file request, i.e., the
HTML
files,
CSS
files, JavaScript files, graphic files,
PDF
documents,MP3s,
etc., and stores them in log files. These log files also include information on
site and Web server errors, page processing time, bandwidth used, visitor
IP
address, referring websites, and much more. Log file analyzers like SmarterStats
interpret this data to create website statistics and reports.
Alternatively, script-based analyzers like Google Analytics require the use of tracking
code (usually JavaScript) on each webpage that is to be tracked. As visitors surf
the website, the code places a cookie on their computer so they have a unique identifier
and can be tracked—provided the visitor is using a browser that supports JavaScript,
has cookies enabled and is not using security software to protect the browser.
Log Analyzers vs. Script-based Analyzers
Each method for gathering website analytics has its benefits and drawbacks. For
example, script-based analyzers only record data from pages that have the JavaScript
tracking code; any pages without the code will not have statistics available. This
is also one of the reasons log file analyzers report higher traffic (views, visits
and hits) than Google Analytics does, as the Web server log files track every interaction
visitors have with a website.
Similarly, because log file analyzers process log file data instead of relying on
forward-facing JavaScript, they have access to information that script-based analyzers
don’t (such as data relating to traffic from spiders and bots, server errors and
bandwidth statistics).
Accuracy of Statistics from SmarterStats and Google Analytics
As previously discussed, users of both analytics program may notice reporting discrepancies,
particularly in regards to visitor counts. Because of the limitations of script-based
analytics, Google Analytics will underreport or misrepresent some website statistics.
Consider:
-
When comparing data on website visits, it is important to realize that SmarterStats
and Google Analytics process data at different intervals. Google Analytics uses
a 30-minute window while SmarterStats uses a 20-minute idle timeout window. For
this reason, SmarterStats will report a higher number of visits for visitors that
keep the browser window open but do not navigate to new pages within the window.
-
Look at the referral reports in SmarterStats. Are there any referrals listed that
are part of the base domain (i.e., IP addresses or aliased domains)? These referrals
are not available in Google Analytics reporting.
-
Hits from people “borrowing” content from your website. Are people linking directly
to documents or images on your website? SmarterStats counts any request for those
files as visits and hits; Google never reports them because JavaScript can’t be
placed on files, just HTML pages.
In the end, SmarterStats provides more accurate website statistics than Google Analytics
because SmarterStats reports all requests to the server, not just what is tagged
with tracking code.
