Google Tag Manager related issues

If you tagged your site using Google Tag Manager, the following issues may prevent you from seeing data.

• Incorrect filter settings
  Incorrect filter settings can affect the data you see, and can inadvertently filter all of your data from your reports. In most cases, this occurs when users apply multiple "Include" filters. For details, see the article on Include and exclude filters.
• Unpublished container
  Check that you published your container after adding the Analytics tag. Changes made to a container do not take effect on a site until you publish the container. So, once you've added or edited tags, you'll need to publish the container in order to make your additions and changes live on the site.
• Tag not firing
  Read "Why is a tag not firing?" in the Google Tag Manager help center.

Analytics tracking code issues

• Did you paste your tracking code in the right place?
  Paste the tracking code right after the opening  tag. For more information, including how to find your tracking code, read Set up Analytics tracking.
• Using incorrect snippet and/or viewing the wrong account, property, or view
  If you track multiple websites and/or have access to multiple Analytics accounts, you might be using the snippet from another property, or you may be looking at reports in the wrong account, or for the wrong property and view. Make sure you are using the correct snippet for your property, and that your are looking at the correct account, property, and view. See Finding the Tracking Code for additional information.
• Extra whitespace or characters
  Be sure to copy the snippet and paste it directly onto your website using either a text editor or an editor that preserves code formatting. Don't use a word processor to copy the snippet from your account.  Doing so can add an extra space or change the quotation marks in the tracking snippet, which requires precise formatting in order to work.
• Customization Errors
  If you are making customizations to the tracking code, make note of the following:
  • function names are case sensitive and should have correct casing
  • boolean values (e.g. true or false) should not be enclosed in quotes
• Incorrect filter settings
  Incorrect filter settings can affect the data you see, and can inadvertently filter all of your data from your reports. In most cases, this occurs when users apply multiple "Include" filters. For details, see the article on Include and exclude filters.
• Other scripts on your page
  If you’re running other scripts on your page, make sure you’re not using any variables that Analytics uses. For more information on variables that the Analytics tracking code uses, visit the developer documentation for the Universal Analytics (gtag.js) JavaScript library.
