How to understand Google Analytics — without hiring an agency

Understanding Google Analytics is less about memorising what every button does and more about knowing where to look for the answer to the question you actually have. This guide is built around the three questions every business owner is really trying to answer when they open GA4.

Question 1: Did more people visit this week than last week?

Go to Reports → Acquisition → Traffic acquisition. In the top right, click the date range and set it to 'Last 7 days'. Then click 'Compare' and pick 'Previous period'.

You'll see two numbers side by side for each channel. The one you want is Engaged sessions — that's the closest GA4 metric to 'real visits'. If it's up versus last week, traffic is genuinely growing. If only 'Sessions' is up but 'Engaged sessions' is flat, you're probably getting more low-quality traffic (often bots or accidental clicks).

Question 2: Which page is doing the most work for me?

Go to Reports → Engagement → Pages and screens. The 'Views' column shows raw page views. The 'Engagement rate' column shows what share of visitors actually engaged with that page.

Sort by Views first — that's your most-trafficked page. Then sort by Engagement rate — that's your most-loved page. Often they're not the same. The page with high traffic but low engagement is broken or off-message; the page with low traffic but high engagement is hiding from the world and you should drive more traffic to it.

Question 3: Why did the number change?

This is the hardest question GA4 answers, because the platform shows you what changed but rarely why. The investigation usually looks like:

  • Open Acquisition → Traffic acquisition and compare to previous period. Which channel moved the most?
  • If it's Organic Search, cross-check Google Search Console to see which queries moved.
  • If it's Referral, click 'Session source / medium' to find the specific referrer.
  • If it's Direct, you probably launched something (email blast, podcast, press) — direct traffic catches everything GA can't categorise.

The 80/20 of GA4 for non-technical owners

If you only check three screens a month, make them: Traffic acquisition (where), Pages and screens (what), and Conversions (results). You can ignore explorations, audiences, attribution, BigQuery exports, and 90% of the rest until you have a specific question those tools answer.

When DIY stops being worth it

If you find yourself opening GA4 less than once a week, the problem isn't your discipline — it's the tool. Most owners only need the answer, not the dashboard. Plainly delivers that answer in a 60-second email every Monday so you stay informed without ever opening GA4 again.

Skip the manual checks.

Plainly connects to your Google Analytics in one click and emails you a 60-second plain-English readout every Monday. $18/month or $199/year for unlimited analyses.

Common questions

How often should I check Google Analytics?

Weekly is plenty for most businesses. Daily checking causes overreaction to noise (single-day spikes rarely mean anything). Monthly is the minimum if you're running paid ads or actively doing SEO.

Do I need to learn SQL or BigQuery for GA4?

No, unless you're a 100-person enterprise running complex attribution. The standard GA4 reports cover everything a small business needs.
