There is a limit to how much data you may collect in the standard (free) edition of Google Analytics.
This is what the Google Analytics Terms of Service currently has to say about it under “2. Fees and Service”:
“Subject to Section 15, the Service is provided without charge to You for up to 10 million Hits per month per account. Google may change its fees and payment policies for the Service from time to time including the addition of costs for geographic data, the importing of cost data from search engines, or other fees charged to Google or its wholly-owned subsidiaries by third party vendors for the inclusion of data in the Service reports. The changes to the fees or payment policies are effective upon Your acceptance of those changes which will be posted at www.google.com/analytics. Unless otherwise stated, all fees are quoted in U.S. Dollars. Any outstanding balance becomes immediately due and payable upon termination of this Agreement and any collection expenses (including attorneys’ fees) incurred by Google will be included in the amount owed, and may be charged to the credit card or other billing mechanism associated with Your AdWords account.”
Please look at the official page for the Google Analytics Terms of Service for the latest updates to terms.
You may be seeing one of the following messages if you exceed that limit:
“You are exceeding our data limits, as outlined in our Terms of Service”, “You have exceeded our data limits, as outlined in our Terms of Service.”, “You are exceeding data limits”, “Your Google Analytics property has exceeded your limit of 10 million hits per month.”, “Your data volume exceeds the limit of 10M hits per month.”, or a similar message.
