Explanation
Analysis of Correct Answer(s)
The correct definition is that a tag is a small snippet of code that is placed on every page of a website.
- Small Snippet: Tags are intentionally designed to be lightweight pieces of code (typically JavaScript) to minimize their impact on a website's loading speed and performance.
- Every Page: Modern tracking strategy, such as with the Google tag (gtag.js), requires site-wide implementation. Placing the tag on every page allows for comprehensive measurement of the entire user journey, enables robust audience building for remarketing, and provides the necessary foundation for firing specific conversion events on particular pages (e.g., a "thank you" page after a purchase).
Analysis of Incorrect Options
- Large snippet: This is inaccurate. Performance is critical, so tags are optimized to be as small and efficient as possible.
- Placed on the home page only: This is too restrictive. It would prevent the tracking of user activity on any other page, making it impossible to measure conversions or understand user behavior across the site.
- Placed on the conversion page only: This describes a more specific piece of code called an event snippet, which signals a conversion action. However, the main global site tag must already be present on all pages, including the conversion page, for the event snippet to function correctly. This option confuses the general tag with a specific event-tracking code.
