Google Analytics review

No. You can install Analytics directly, and for a site running one tracking script, that's simpler. Tag Manager earns its place at the second script: an ad pixel, a CRM snippet, a conversion tag for a campaign. From there, it's a developer request every time marketing needs something measured, or a few clicks in a dashboard. One tag doesn't justify the extra layer; four do.

For most sites not spending real money on ads, yes. It answers whether people are arriving, what they look at, and whether they do what you wanted. It runs out at attribution: it can tell you a campaign sent four hundred visits, but not that eleven became customers worth more than everything else you spent that month. Once ad spend is on the line, close that gap with a tool that follows a lead into your CRM.

Learn enough to answer your three or four real questions, and ignore the rest. The common mistake is treating GA4 as something to master: it's a deep tool built for analysts, and most business owners need a handful of reports they check monthly. Set up the conversions that matter, save those reports, and stop. If even that feels like too much, a lighter privacy-focused analytics tool covers most of it with a fraction of the interface.

Yes, because they answer different halves of the same question. Analytics tells you what people did once they arrived; Search Console tells you how they found you: the literal queries, and which pages Google indexed. The search-query data exists nowhere else. Both are free, and the pair is better than either alone.
