Using Google Analytics
Google Analytics is a great free service for measuring traffic on up to five web sites. It can help you learn things like how many users are visiting your tumblelog — and how often, which of your posts are the most popular, which search terms visitors are finding you through, and where in the world your visitors are coming from.
Step 1. You'll need a Google/Gmail account. If you don't have one yet, it only takes a minute to sign up.
Step 2. Head to http://www.google.com/analytics/ and log in with your Google account.
Step 3. Click "Add Website Profile".
Step 4. Select "Add a Profile for a new domain".
Step 5. In the URL field, enter your tumblelog's URL. This will be something like "david.tumblr.com". If you're using a custom domain, enter that instead.
Step 6. Click "Continue".
Step 7. Highlight and copy the code that appears on the next page.
Step 8. Open your Tumblr Dashboard in a new window and click the "Customize" link.
Step 9. Paste the Google Analytics code into the "Description" field and click "Save".
Step 10. Go back to the Google Analytics window and click "Finish".
All done!
You should now see your tumblelog added to your Google Analytics "Website Profiles". It can take Google a little while to start displaying your traffic report. Until Google's system has started processing your data, its "Status" label should read "Tracking code not verified".
Now you can log into Google Analytics and click "View Reports" for detailed traffic metrics about your tumblelog.
