If you publish blog posts, share links on social media, send emails, create YouTube videos, or promote affiliate and digital products, you eventually need to answer a basic question:
Where are my website visitors actually coming from?
Google Analytics 4 provides several acquisition reports for this purpose. The Traffic Acquisition report is designed to show where new and returning sessions originate, while the User Acquisition report focuses on how new users first found the website or app.
For day-to-day website marketing analysis, Traffic Acquisition is usually a useful starting point because it helps you examine sessions from Organic Search, Direct, Referral, Organic Social, Email, Paid channels, and other traffic sources.
Key Takeaways
- Use Traffic Acquisition to study session-level traffic sources.
- Use User Acquisition when you want to know how new users first discovered the site.
- “Source” identifies where traffic originated.
- “Medium” identifies the type of traffic.
- “Session source / medium” often gives a clearer marketing view.
- Direct traffic does not always mean someone typed your URL.
- Use UTM parameters for links you control when appropriate.
- Connect source data with landing pages and meaningful actions.
Start With the Traffic Acquisition Report
Google’s current GA4 instructions are:
- Sign in to Google Analytics.
- Select Reports.
- Open Acquisition.
- Select Traffic acquisition.
If you cannot see the report, Google notes that it may have been removed from the default navigation and can be restored by users with sufficient permissions.
The default report may show traffic grouped by channel.
Typical channels can include:
- Organic Search.
- Direct.
- Referral.
- Organic Social.
- Paid Search.
- Paid Social.
- Email.
- Affiliates.
- Display.
- Video.
- Other channel groups.
Understand Source, Medium, and Channel
These terms are easy to confuse.
Source
Source identifies the particular platform, website, app, or location that referred traffic.
Examples:
- bing
- facebook.com
- youtube
- newsletter name
- direct
Google defines source as the specific platform, website, app, or online location that referred the user.
Medium
Medium describes the type of traffic.
Examples:
- organic
- referral
- cpc
- social
- none
Default channel group
This groups sources and mediums into broader categories such as Organic Search, Direct, Paid Social, and Email.
Use Session Source / Medium
For practical analysis, change the primary dimension to:
Session source / medium
You might see values such as:
- google / organic
- bing / organic
- facebook.com / referral
- newsletter / email
- youtube.com / referral
- direct / none
Google describes session source / medium as the source and medium associated with the session.
This can tell you more than the broad channel alone.
For example:
Organic Search tells you the category.
google / organic tells you the source and type.
Understand User Acquisition Versus Traffic Acquisition
These reports answer different questions.
User Acquisition
Question:
How did this person first discover my website?
It uses dimensions such as:
- First user source.
- First user medium.
- First user source / medium.
Traffic Acquisition
Question:
What source produced this particular session?
It uses:
- Session source.
- Session medium.
- Session source / medium.
Google specifically distinguishes User Acquisition as user-scoped and Traffic Acquisition as session-scoped.
A person might first discover your site from Google but return later from an email.
Both interactions matter, but they answer different marketing questions.
Analyze Organic Search
Filter or search the report for:
google / organic
Google’s current Traffic Acquisition documentation specifically gives this as an example for isolating organic Google Search traffic.
Review:
- Sessions.
- Engaged sessions.
- Engagement rate.
- Key events.
- Revenue if applicable.
- Landing pages.
Ask:
- Is search traffic increasing?
- Which pages receive it?
- Does search traffic engage?
- Does it subscribe?
- Does it visit product pages?
GA4 tells you what happens on the website.
Google Search Console tells you which Google queries and pages generated search impressions and clicks.
Use both systems for different questions.
Analyze Referral Traffic
Referral traffic comes from links on other websites.
Possible sources include:
- Blogs.
- News sites.
- Directories.
- Partner sites.
- Community websites.
- Product review pages.
- YouTube links in certain contexts.
- Other external websites.
Google Analytics automatically identifies the referring domain when referral information is available.
Review whether the referring site:
- Makes sense.
- Sends engaged visitors.
- Links to an appropriate page.
- Produces subscribers or customers.
- Is actually a payment processor or another domain that should not be treated as a marketing referral.
Watch for Unwanted Referrals
If your checkout uses an external payment processor, a visitor might leave your website, pay, and return.
Without the right configuration, GA4 may attribute the returning session to the payment provider instead of the true marketing source.
Google recommends unwanted-referral configuration for certain third-party domains such as payment processors when appropriate.
Do not change referral settings casually.
Incorrect configuration can remove useful attribution data.
Understand Direct Traffic
“Direct” does not always mean the visitor typed your website address.
GA4 uses direct / none when it does not have a clear referral source.
Google lists possible reasons including:
- Typed URLs.
- Bookmarks.
- Links in offline files.
- Missing campaign parameters.
- Redirects that remove tracking data.
- Certain URL shorteners.
- Ad blockers or other tracking limitations.
This matters because a large Direct category may indicate tracking problems rather than strong brand recognition.
Track Email Traffic Properly
Suppose you send an email with:
Analytics may not always classify the visit the way you expect.
A tagged campaign link can identify:
- Source.
- Medium.
- Campaign.
- Content variation.
Google explains that traffic-source information can be populated through manual tagging or integrations and auto-tagging.
A simple email campaign might use:
- Source: newsletter
- Medium: email
- Campaign: august_ebook_series
Then GA4 can group the sessions more meaningfully.
Track Social Media Links
You can create consistent campaign tags for links shared on:
- Facebook.
- LinkedIn.
- X.
- Pinterest.
- Instagram where clickable links are available.
- Other social channels.
For example:
utm_source=facebook
utm_medium=social
utm_campaign=ebook_launch
Use a naming convention before publishing.
Do not use:
- Facebook one week.
- fb the next.
- Facebook.com later.
- socialmedia for another campaign.
Inconsistent naming creates fragmented reports.
Track YouTube Traffic
Links from YouTube can appear under referral, organic video, or other classifications depending on the source and tagging.
If you control a link in a description, use consistent campaign parameters when appropriate.
For example:
- Source: youtube
- Medium: video
- Campaign: ebook_playlist
Then compare:
- Sessions.
- Engagement.
- Lead-magnet signups.
- Product-page visits.
Do not assume video traffic is valuable simply because someone clicked.
Connect Sources With Landing Pages
Knowing that traffic came from Google is only half the question.
You also need to know:
Where did those visitors enter the site?
Google’s Landing Page report can be combined with Session source / medium as a secondary dimension. Alternatively, the Traffic Acquisition report can use Landing Page + Query String as an additional dimension.
This lets you answer:
- Which blog posts attract Google visitors?
- Which page receives Facebook traffic?
- Which landing page receives email subscribers?
- Which review page attracts referrals?
- Which campaign sends visitors to the wrong page?
Evaluate Engagement
Traffic volume alone can mislead you.
Compare sources by:
- Engaged sessions.
- Engagement rate.
- Average engagement time.
- Key events.
- Purchases.
- Lead-magnet signups.
- Contact submissions.
Imagine:
Source A: 1,000 sessions and 2 signups.
Source B: 100 sessions and 15 signups.
Source B may deserve more attention even though it produces less traffic.
Create Meaningful Key Events
GA4 becomes more useful when you track actions that matter.
Possible events include:
- Lead-magnet signup.
- Product purchase.
- Contact submission.
- Checkout start.
- Important button click.
- Course enrollment.
- Download.
- Video engagement.
Do not mark every page view as a key event.
A key event should represent an action that matters to the business.
Compare Your Three Main Traffic Questions
Question 1: Where do sessions come from?
Use:
Traffic Acquisition
Question 2: How did new users first find me?
Use:
User Acquisition
Question 3: Which page did traffic enter through?
Use:
Landing Page report
Together, these reports provide a more complete picture.
Create a Monthly Traffic Review
Once a month, record:
- Total sessions.
- Organic Search sessions.
- Direct sessions.
- Referral sessions.
- Organic Social sessions.
- Email sessions.
- Paid sessions if applicable.
- Top sources.
- Top landing pages.
- Engagement rate.
- Key events.
- Subscriber conversions.
- Product conversions.
Then write:
What changed?
Why might it have changed?
What should I investigate?
What should I continue?
This prevents analytics from becoming a collection of numbers you never use.
A Practical Example
Suppose a small online-business website publishes:
- Six blog posts per day.
- YouTube videos.
- Facebook posts.
- LinkedIn posts.
- Email newsletters.
After one month, GA4 shows:
google / organic: visitors entering through educational blog posts.
facebook / social: visitors entering through several recent posts.
newsletter / email: smaller traffic volume but stronger engagement.
direct / none: a substantial category.
The next analysis should not be:
“Which number is biggest?”
Instead:
- Which source brings qualified visitors?
- Which pages attract them?
- Which sources produce email subscribers?
- Is Direct unusually large because campaign links are untagged?
- Which content should be repeated or improved?
Analytics becomes a decision tool.
Common Tracking Mistakes
Looking only at total users
You cannot tell which marketing effort is working.
Confusing User Acquisition with Traffic Acquisition
They use different scopes.
Assuming Direct means typed URL
Missing attribution can also produce Direct traffic.
Failing to tag email links
Email visits may be classified incorrectly.
Using inconsistent campaign names
The same campaign can become several report rows.
Ignoring landing pages
Traffic source without destination provides incomplete context.
Tracking traffic but not outcomes
Visitors are useful only when they support a meaningful reader or business objective.
Changing settings without understanding them
Incorrect referral or attribution configuration can distort data.

Open Reports → Acquisition → Traffic Acquisition.
Step 2
Review Default Channel Group.
Step 3
Change the dimension to Session source / medium.
Step 4
Review Organic Search, Social, Email, Referral, and Direct.
Step 5
Add landing-page context.
Step 6
Compare engagement.
Step 7
Review key events.
Step 8
Check Direct traffic for tracking issues.
Step 9
Standardize UTM naming.
Step 10
Record monthly results.
Conclusion
Google Analytics 4 can show where website traffic comes from, but the most useful analysis goes beyond the total number of visitors.
Use Traffic Acquisition to understand session sources, User Acquisition to understand first-time discovery, and Landing Page reporting to see where visitors enter the site. Then connect those sources with engagement, subscriber actions, and product-related events.
Pay particular attention to Direct traffic, because missing referral or campaign information can cause visits to appear there.
Open your GA4 Traffic Acquisition report and identify your five largest Session source / medium combinations before deciding which marketing channel deserves more work.
