building a client dashboard in Looker Studio, what do you include?

less than you think. clients look at the first page and stop. page one for us: a few scorecards (conversions, sessions, organic clicks) with comparison to the previous period, one line chart of organic clicks over time, and a short text box where we write what changed and why. that text box gets more attention than any chart. page two onwards is the detail: top landing pages, conversions by channel, search console queries, and a date range control on every page. one practical thing, the GA4 connector has quota limits and a page with loads of GA4 charts can start throwing errors when the client opens it. keep each page lean or extract the data first.
