Understanding the difference between a dimension and a metric is important for developing frameworks for digital marketing strategy and goals. There is no better example that I can think of than reviewing the difference between landing pages and entrances. In theory, they are the same thing but in reality, the distinction is necessary. The number of sessions for the dimension landing page should match the number of entrances for a page. But, there is a difference in how each is used. You can also review where to find landing page and entrances in Google Analytics. But, to further understand the difference between one, the landing page, which is a dimension and entrances, which is a metric, you can only filter based on a dimension. I’ve explained previously that metrics for a landing page dimension are under the site content section of Google Analytics. You will also find the metric, entrances, under the Site Content dimension ‘All Pages’. But, if you drill down into other information underneath the behavior and site content section of Google Analytics, such as going into Behavior > Site Content > Content Drilldown you can set up a secondary dimension for specific page paths by landing page and filtering by site entrances is not an option.
Why is this important? Because you need to know the difference between a dimension and a metric in addition to knowing how to communicate the difference between landing pages and entrances to clients. If anything, it demonstrates your depth as a digital marketing consultant. If you’d like to learn more about dimensions and metrics in light of setting up and understanding digital marketing frameworks and how everything works together in defining goals, metrics, KPI’s, dimensions, and targets, I recommend further reading through Avinash Kaushik’s DUMB objectives article. When you really understand these terminology it will ensure your ability to establish digital marketing benchmarks for clients and provide results.
