How to Analyze Your Website's Performance

What the Metrics Mean

First, let’s look at what certain terminology refers to. Here’s a glossary to help you understand the key phrases you’ll encounter in any analytics tool, and how they relate to one another.

Page views: Each time someone loads a page on your site, it generates a page view, no matter who loads it and how often they load it. It’s a crude, but still widely used, measure of a site’s traffic.

Visits: This measure evaluates how many users have spent time on the site, regardless of the number of pages each user views.

Unique visitors: As its name suggests, this measure counts only the unique users who visit the site. If a particular visitor comes to the site every day, he or she counts only as a single unique.

Pages/visit: How many pages does each visitor see during a session? Higher numbers are considered better.

Average visit duration: How much time do users spend on the site during each visit? Longer is better.

Bounce rate: What is the percentage of users who view only one page on the site and then leave? Lower is better.

% new visits: This measure is the percentage of your traffic from first-time users who have never been to the site before. Generally, lower is considered better, as it means you’re encouraging repeat visits.

Google Analytics

The vast majority of websites that use an analytics tool rely on Google Analytics, for a couple of reasons. First, it’s easy to use and understand. Second, it’s free if your website has 10 million page views per month or less. (After that it’s a hefty $150,000 a year.)

Google Analytics is a powerful tool, but its price tag is its best feature: It's free.
Getting started with Google Analytics is easy. When you register (a standard Google account is all you need), you receive a unique snippet of code that you then place on your website’s template so that it appears on each page. Once you've done that, Google collects data every time a visitor’s Web browser loads that code.

After Google has collected some data (give it a few days at least), log in to your dashboard to see a default view of your site’s traffic metrics over the previous month. You’ll find the traffic graph (Visits is the default) up top. Below that, links to demographic and technical data appear, including information about the language of each user.

You'll spend most of your time manipulating the graph at the top. Use the drop-down arrow next to the date to tweak the timeline you’re analyzing, and use the Compare to past checkbox to overlay a past period’s data. You can swap between viewing Visits, Uniques, and Pageviews (among other metrics) by using the selector beneath the Overview tab.

Compare your site's performance across date ranges to measure the effectiveness of any changes you make.
On the left side of the screen are additional links to more detail, which can be useful. Clicking Demographics > Location will generate a nice map of where your visitors live (don’t be surprised if most are in the United States). Try using the chart type buttons beneath the graph to generate a more useful pie chart from this data.

The big draws in the sidebar are the Traffic Sources and Content links. Click Traffic Sources > Sources > All Traffic to see where your users are coming from. Under this header, the Search Engine Optimization > Queries link will give you a sense of the most popular search keywords that have the potential to lead to your site, and what portion of those clicks you’re grabbing. The Content > Site Content > All Pages link is where you’ll get an idea of what specific pages or products are generating the most traffic. Again, manipulate the timeline to ferret out long-term and short-term trends.

Google Analytics can connect to your AdWords campaign, allowing you to measure how your online ad campaign is performing.
One of Google Analytics’ selling points is its ability to connect to your AdWords campaign (so you can track whether your own ads are bringing in visitors). If you run ads on your site, click Content > AdSense > Overview to see which pages on your site are earning the most revenue (and how much). You’ll need to link them together in the AdSense tool first.
