Yeah, whoever designed this UI clearly never had to actually run ads. The keyboard shortcuts are the only thing saving my sanity - G+A to ads, G+K to keywords, G+C back to campaign level, G+J for ad sets. Use them religiously.
If you're new, the search bar actually works surprisingly well. Type what you need and it drops you in the right place.
But honestly, skip the fluff. Get your conversion tracking sorted first - tags from Google Analytics, call ad numbers, whatever fits your funnel. Avoid those pointless micro-conversions like "button clicked" unless they're part of a real step.
First campaign? Just follow the guided tour. Google's shoving everything into automated and AI-driven setups, so half the stuff you learn now will be obsolete in a few months anyway.
If you don't want to master every campaign type, run a Performance Max and a Demand Gen - that covers most bases. But throw in at least one Search campaign. Then dig into the automatic suggestions and turn off anything you don't want applied without your consent. You did that on Meta, right? Hope so.
