If you look at Google's current explanation on how to get your Analytics profile ID, they will tell you to look in the URL of your Google Analytics reports. I went ahead and looked at the reports to find a different URL structure that didn't include the id described. Anyway, here's a much easier way to find your Google Analytics profile ID.

Get analytics profile ID

1. Sign into your Google Analytics account.
2. Click on the 'Admin' tab on the top left of the screen.
3. Click on the account you want to find the profile ID for.
4. Click on the 'Account Settings' tab. Notice the 'Account id', this is your profile id.
