Here are the metrics options for your custom report.
After that, enter a name that describes your group of metrics and add the metrics, or table columns (see image).
You can also click on Add Dimensions; adding more than one offers the opportunity to drill down into the data. To limit your report to a portion of the data, click on Add a Filter. Once you're satisfied with your settings, save your report.
In this case, I've restricted the report to portions of the visitors and content metrics and set up one dimension option.
When you save your report, Google Analytics places that information into a graphic as seen here:
Be aware that this custom reporting technique, while effective, doesn't give you access to all the data that may interest you. For example, I wanted to access the popular keywords that people were using to find my site.
To find that information, I had to go back to the Standard Reporting tab and, in the options on the left, drill down into the settings. The path was: Traffic Sources: Sources: Search: Overview. Once In the Primary Dimension section, click on Keyword for that information.
There's a lot of information on that screen, so here's a look instead at the Primary Dimension section on its own. In this screenshot you see the most popular keywords, how many visits, the amount of time spent on the page and so on. (There's more data to see, but I cropped that for the sake of visibility.)
Using this data will help you improve client/customer retention, as you can see what keywords bring visitors to your site and keep them there.
