The Only 5 GA4 Numbers That Matter for Your Business
Google Analytics 4 has over 50 built-in reports. Most of them do not matter for your business. If you are a small business owner trying to understand whether your website is working, you need five numbers. Not fifty. Five.
This guide tells you exactly which five metrics to check, where to find each one in GA4, and what each one means for your SEO strategy.

Why Most GA4 Reports Do Not Matter
GA4 was built for enterprise marketing teams that need granular audience segmentation, custom event funnels, and predictive analytics. If you run a small business website, you do not need most of that.
Here is what you can skip entirely:
| GA4 Section | Why You Can Ignore It |
|---|---|
| Monetization | Only relevant for e-commerce with purchase tracking configured |
| Retention | Designed for apps and subscription services |
| Demographics | Interesting but rarely changes what you do |
| Real-time | Watching traffic in real-time is not decision-making |
| Custom Explorations | Analyst tool, overkill for most sites |
| Predictive Audiences | Requires massive data volume to be useful |
That leaves Acquisition and Engagement. From those two sections, you need five numbers.
Number 1: Organic Search Sessions
What it is: The total number of visits to your site from people who found you through Google or another search engine.
Where to find it: Reports > Acquisition > Traffic Acquisition. Look at the row labeled "Organic Search" and the "Sessions" column.
Why it matters: This is the single best measure of whether your SEO is working. More organic sessions means more people are finding your site through search engines. If this number is growing, your SEO efforts are paying off. If it is flat or shrinking, something needs investigation.
What to watch for:
- Growing steadily — Your content and SEO are working. Keep doing what you are doing.
- Flat — You are maintaining but not gaining. Look for new keyword opportunities or content improvements.
- Declining — Investigate immediately. Check for indexing problems, lost rankings, or technical issues.
Do not obsess over daily fluctuations. Organic traffic naturally varies from day to day. Compare week to week or month to month for meaningful patterns.
Number 2: Engagement Rate
What it is: The percentage of sessions where the visitor stayed more than 10 seconds, viewed more than one page, or completed a conversion event.
Where to find it: Reports > Engagement > Pages and Screens. The "Engagement Rate" column shows this for each page.
Why it matters: High traffic with low engagement means people are finding your site but not getting what they came for. This often indicates a mismatch between what your page title and meta description promise in search results and what the page actually delivers.
What good looks like:
There is no universal "good" engagement rate because it varies by industry and page type. A blog post about how to do something might naturally have lower engagement than a service page because people find their answer and leave. The most useful approach is comparing your own pages to each other:
- If most of your pages have engagement rates around 50-60% but one page is at 20%, that page has a problem.
- If a page's engagement rate drops significantly compared to the previous month, something changed — investigate.
Connection to SEO: Google uses user behavior signals when evaluating pages. A page where visitors consistently engage sends a different signal than a page where visitors immediately leave. Improving engagement rate on your key pages supports your rankings over time.
Number 3: Top Landing Pages by Organic Traffic
What it is: The specific pages on your site where organic search visitors arrive first.
Where to find it: Reports > Engagement > Landing Page. Filter by adding a condition where "Session default channel group" equals "Organic Search." Sort by Sessions descending.
Why it matters: This tells you which pages Google is actually sending people to. Often the results are surprising — a blog post you wrote six months ago might be pulling in more organic traffic than your homepage.
What to look for:
- Your top 5-10 pages — These are your SEO workhorses. Protect and improve them. Make sure their title tags and content stay current.
- Pages with traffic but low engagement — These are ranking well but not satisfying visitors. The content needs to better match search intent.
- Important pages with zero organic traffic — Your services page or product pages should be getting some organic traffic. If they get none, they may not be indexed or may not be optimized for the right keywords.
Number 4: Traffic Source Breakdown
What it is: The percentage of your total traffic that comes from each channel — organic search, direct, referral, social, email, and paid.
Where to find it: Reports > Acquisition > Traffic Acquisition. Look at the pie chart or the Sessions column for each channel.
Why it matters: Healthy websites have diversified traffic sources, but for SEO purposes, you want organic search to be a significant portion. If 90% of your traffic comes from direct visits and only 5% from organic search, your site is essentially invisible in Google.
Benchmarks to consider:
| Scenario | What It Suggests |
|---|---|
| Organic search is your largest channel | Your SEO is working as your primary acquisition driver |
| Direct is your largest channel | You have brand recognition, but SEO may be underperforming |
| Social is your largest channel | Your social media is strong, but you are missing search traffic |
| Organic search is under 20% of total | SEO needs focused attention |
This metric also helps you understand risk. If organic search is 80% of your traffic and Google's algorithm changes or your rankings drop, your business feels it immediately. Diversification matters, but for most small businesses, growing organic search is the priority.
Number 5: Month-over-Month Organic Traffic Trend
What it is: Whether your organic search traffic went up or down compared to the previous month.
Where to find it: Reports > Acquisition > Traffic Acquisition. In the date picker (top right), select "Last 28 days" and enable "Compare: Preceding period." Look at the Organic Search row to see the percentage change.
Why it matters: This is the simplest answer to the question every business owner asks: "Is my SEO getting better or worse?" A single month's number does not tell you much, but the trend over 3-6 months tells you everything.
How to read the trend:
- Up 3+ months in a row — SEO is clearly working. Document what you are doing so you can keep doing it.
- Flat for 3+ months — You have plateaued. Time to look for new opportunities — what keywords should you target next?
- Down 1 month — Do not panic. Check for seasonal patterns, holidays, or a known Google algorithm update. One month is not a trend.
- Down 2+ months in a row — Investigate. Check your Google Search Console data for ranking drops, indexing issues, or crawl errors.
Seasonal awareness: Many businesses have natural traffic fluctuations. A landscaper's website will get more traffic in March than December. Compare year-over-year (same month last year) in addition to month-over-month for a more accurate picture.
How to Check All 5 in Under 10 Minutes
Here is the exact routine:
Step 1 (2 minutes): Open GA4. Go to Reports > Acquisition > Traffic Acquisition. Set date range to "Last 28 days" with comparison to preceding period. Note your Organic Search sessions and the percentage change. Glance at the traffic source breakdown.
Step 2 (3 minutes): Go to Reports > Engagement > Landing Page. Add a filter for organic traffic. Sort by sessions. Note your top 5 landing pages and their engagement rates.
Step 3 (2 minutes): Look at your overall engagement rate across organic landing pages. Flag any pages with engagement rates significantly below your average.
Step 4 (2 minutes): Write down three things: organic traffic trend (up/down/flat), your top performing page, and one page that needs attention. That is your SEO status for the month.
Step 5 (1 minute): If anything looks wrong (traffic drop, new page with zero sessions, sharp engagement decline), investigate further or ask your data a specific question.
Ten minutes. Monthly. That is all a small business needs from GA4.
How Brass-SEO Shows You These Numbers Automatically
Brass-SEO connects to your GA4 and Google Search Console accounts, then lets you ask for these numbers in plain English instead of navigating GA4's interface. Our getting started guide walks through the full setup.
Instead of clicking through three reports and setting filters, you can ask:
- "How is my organic traffic trending?"
- "Which pages get the most search traffic?"
- "What is the engagement rate on my top pages?"
- "Did my traffic go up or down this month?"
The AI pulls data from both GA4 and GSC together, which means you get the full picture — not just traffic numbers from GA4, but also ranking positions and click-through rates from GSC — in a single answer.
This is especially useful for number 3 (landing pages) because Brass-SEO can cross-reference which pages get organic traffic (GA4) with which keywords those pages rank for (GSC) and whether those pages are properly indexed by Google. That cross-referencing is the part that takes the most time manually, and the reason we built the tool.
If you want to try it, setup takes about two minutes. See the getting started guide for the walkthrough, or go directly to your dashboard if you already have an account.
Frequently Asked Questions
What about conversions? Why are they not in the top 5?
Conversions are important, but they require custom setup in GA4. You need to define what counts as a conversion for your business (form submission, phone call click, purchase) and configure the tracking. Most small businesses have not done this yet. The five metrics in this guide work with GA4's default configuration — no custom setup required. Once you have conversion tracking configured, it becomes a sixth essential number.
How often should I check these numbers?
Monthly is sufficient for most small businesses. Weekly is fine if you are actively working on SEO and want to see faster feedback. Checking daily leads to overreacting to normal fluctuations. The exception: if you just published new content or made significant changes to your site, checking weekly for the first month helps you see the impact.
What if my organic traffic is very low (under 100 sessions per month)?
Low organic traffic usually means your site is new, has few indexed pages, or is not optimized for search terms people actually use. Focus on getting your pages indexed by Google first, then work on targeting the right keywords. Even at low traffic levels, watching the trend matters — going from 30 to 60 sessions is a 100% increase and a strong signal that your SEO is working.
Is engagement rate more important than bounce rate?
They measure the inverse of each other in GA4. Engagement rate is the percentage of engaged sessions; bounce rate is the percentage that were not engaged. Focus on whichever feels more intuitive to you — they tell the same story from different angles. We recommend engagement rate because it is a positive metric (higher is better), which makes trends easier to read at a glance. For a deeper explanation, see our GA4 traffic report guide.
Can I get these numbers without logging into GA4?
Yes, if you connect your GA4 and Google Search Console accounts to Brass-SEO. The AI reads your data and can give you all five numbers in a single conversational response. You can also ask follow-up questions like "why did my engagement rate drop?" and the AI will investigate using both your GA4 and GSC data. If you have not connected your accounts yet, GA4 is the only way to access this data directly.
