1. How many Sessions per month your site receives.
Think of Sessions as the number of times someone visits your site to accomplish something. Maybe they arrive via search, or by directly typing in your URL, or by clicking a link in a social media share. However they arrive, and however long they stay, a “session” has started.
The official Google Analytics definition of a session is a group of interactions one user takes within a given time frame on your website (and Google Analytics defaults the time frame at 30 minutes).
What’s a good number for you? There’s no way to answer that. But you might be interested in knowing that I’ve pulled the monthly numbers you see in this tutorial directly from a restaurant in San Diego with a single-location.
