Using google analytics at least a few days a week there are some sections that I check regularly that are interesting (referrals, on-page SEO, conversion goals, and my created dashboard) but when I venture from this norm, I can find some fascinating stuff. What is everyone's go-to section that they HAVE to check when using GA? Your fellow curious analytics user BeckySEO
Mainly the acquisition section to check where my traffic is coming from. Beside that I also check the Technology section to see what resolutions my visitors are using when I am planning to swop stuff on my websites.
EVENTS. I want to know what people are clicking on when they get to the website. I have most (although not all) links marked with an EVENT tracker so I can see what's working to attract user attention and what isn't.
I usually check the landing page and search queries to know which pages are getting traffic, just so I know what pages I should focus on.
I check the Referral Traffic to see what sites bring traffic, the keywords to see what the users are searching for (Acquisition) and the site content section to see what are my most visited pages (Behavior).
