Default channel groupings in Google Analytics is what you call the different traffic sources in your Google Analytics account. They are comprised of the following:
- Organic Traffic
- Direct Traffic
- Social Traffic
- Referral Traffic
- Email Traffic
- Paid Traffic
- Display Traffic, and the
- Others Traffic
Google Analytics Channel Groupings Technical Definition
Some of the default channel groupings are self-explanatory like email and social, but there are nuances as to how Google Analytics categorizes them.
If you want to be technical, Google defines these as…
|Direct||Source exactly matches direct AND Medium exactly matches (not set)OR Medium exactly matches (none)|
|Organic Search||Medium exactly matches organic|
|Social||Social Source Referral exactly matches Yes OR Medium matches regex ^(social|social-network|social-media|sm|social network|social media)$|
|Medium exactly matches email|
|Affiliates||Medium exactly matches affiliate|
|Referral||Medium exactly matches referral|
|Paid Search||Medium matches regex ^(cpc|ppc|paidsearch)$ANDAd Distribution Network does not exactly match Content|
|Other Advertising||Medium matches regex ^(cpv|cpa|cpp|content-text)$|
|Display||Medium matches regex ^(display|cpm|banner)$ORAd Distribution Network exactly matches Content|
|(unavailable) or (other)||Sessions don’t match any channel description|
You can find more about them from Google’s Help Center.
Depending on your website’s traffic, these default channel groupings might not appear in your reports. For example, here’s a screenshot for one Google Analytics account I’m managing.
You’ll notice that there is no Display Traffic or the other channel groupings from Google.
This simplifies what you see in the reports so you can focus on the things that matter the most — the kind of traffic that you already have instead of what you don’t have.
Most Common Default Channel Groupings in Google Analytics Explained
1. Organic Traffic
Organic traffic is the kind of traffic that comes from search engines. When people search for something on Google (or Bing, or any other search engine), a list of websites shows up. This page is called a search engine results page (or SERPs). When people click on one of these results, that visit is counted in the organic traffic of that website.
It is the best, most sought-after traffic by marketers. It’s the main reason why content marketing is on the rise today. The results of organic traffic are exponential.
When marketers talk about SEO, it’s all about increasing the website’s organic traffic. Just remember that SEO is not static. Changes happen. A lot.
No matter how optimized your website is, if you don’t create and distribute content, you will never rank high on Google and other search engines.
Example: Jon searches in Google for the keyword “email marketing statistics 2020.” He sees the results of his search. He clicks on one of the results and your website page on Email Marketing Statistics 2020 loads.
2. Direct Traffic
Direct traffic is the kind of traffic that comes from people directly typing or entering your website’s URL on their browsers. If someone bookmarks your page, then later goes back and open it, that’s counted as direct traffic.
It’s usually an indication of brand awareness or repeat visits. After all, it’s highly unlikely that you visit a website by typing a URL if you haven’t heard of the brand somewhere else, or know it’s URL for that matter.
From the user’s perspective, direct traffic usually comes from bookmarks or autocomplete in the URL — which is similar to typing it directly. The only difference is that you had a little help from your browser.
Example: Jon realizes that Christmas is around the corner. He opens up Safari and starts typing “amaz” then the browser autocompletes the URL to amazon.com. He hits enter and Amazon’s website shows up.
Caveat: see email traffic below
There’s also another instance where direct traffic might increase without being the result of people typing directly your website. It involves the transfer of traffic from a secured site (https) to an unsecured site (http).
Example: Jon is browsing this particular page. Then he clicks on a link to http://domain.com. Since my website is secured and the target site is not, GA will count Jon’s visit as direct traffic instead of referral (see referral traffic below).
3. Social Traffic
Social traffic is the kind of traffic that comes from social networks. This happens when people share a link on Facebook, Twitter, Instagram, etc. and you click on it.
Quora, Reddit, and other similar sites also fall under here. But it depends on how Google categorizes the site. In short, it depends on the document referrer field and matches the value there to a list of known social networks. If it doesn’t have a match, it will fall under referral Traffic.
Example: Jon is scrolling on Facebook and sees a Tasty video about pasta cooked 4 ways. He sees how it’s made and thinks to himself, “I can do that.” He clicks on the link in the post to see the full recipe. Tasty’s website loads with the specific recipe for that video.
Caveat: See others traffic and UTM tags
4. Referral Traffic
Referral traffic is the kind of traffic that comes from other websites.
If done right, this is the result of effective content marketing. What happens is other people/organizations write about you/your products/services on their own websites.
Since they have their own audience, when they click on that link, they land on your own website.
Google Analytics counts that as referral traffic. The website that links to your site is called the referring website/domain.
Example: Jon is reading an article from wistia.com. He reads an interesting statistics saying that by 2019, video content will comprise of 80% of all consumer internet traffic. He noticed the link, so he clicks on this and lands on another website (smallbiztrends.com). From smallbiztrends.com’s analytics account, Jon’s visit is counted in their referral traffic. The referring website/URL/domain is wistia.com.
5. Email Traffic
Email traffic is the kind of traffic that comes from your email campaigns.
Take note that not all links in your emails go to this traffic. To make sure it appears properly under this channel grouping, you have to integrate your email marketing software with Google Analytics or manually tag (UTM parameters) your links — and make sure the medium parameter is exactly “email.”
If neither one of those two options is met, GA will count that link click (visit to your website) under direct traffic. This skews your data because you might think that your email campaigns aren’t working.
Example: Jon received two emails from an eCommerce website. Email 1 contains an announcement for a sale coming up. It is sent via their email marketing software. Jon clicks on the link and lands on the website. GA counts this as email traffic. Email 2 was sent by a customer representative about a complaint he had. The email linked to the terms and conditions page. Since the email was manually sent and no UTM parameters were added, this traffic is counted as direct traffic.
6. Paid Traffic
Paid traffic is the kind of traffic that comes from paid advertisements. These are ads from Google Ads or Bing Ads. To be more specific, links with the medium “ppc” or “cpc” (or the ones indicated in the table above) are the ones tracked.
You can customize this, along with other settings, in the admin settings of your Google Analytics account. You can find out more information about how to do this in my previous post about paid traffic.
7. Display Traffic
Display traffic is the kind of traffic that comes from paid advertisements as well. Unlike Paid Traffic, this kind of traffic requires the medium parameter to be equal to “display.”
I’m sure you’ve visited sites that are showing you ads. If you click on one of those banner ads, most of the time, your visit which leads to another website will be counted as display traffic.
You’d often find ads on news or media outlets, bloggers or affiliate sites. If it involves a form of pretty graphics, those are display ads.
Refer to the table above to see which parameters direct traffic is counted in your GA account.
8. Others Traffic
Others traffic is the kind of traffic that comes from traffic that doesn’t fall under the default channel grouping definitions. This usually happens when you use custom parameters (UTM tags) in the links that you share.
Remember that UTM parameters require some fields to work. Items 1-4 are required; while 5-6 are optional:
For example, if you added “facebook” in the source parameter and used “post” in the medium parameter, this will show up in the Others traffic. For it to appear under Social traffic, you either have to add the value of “social” in the medium parameter.
You can learn more about UTM tags here.
Here’s a final note the default channel grouping in Google Analytics. You can change the rules that govern the way traffic is grouped into these buckets in the admin section of your Google Analytics account.
One popular use case for changing the default channel groupings is to separate the traffic coming from advertisements on social from the traffic coming from ads via search. You’d need to create a custom channel groupings in your Google Analytics account.

Frequently Asked Questions
What are Google Analytics Default Channel Grouping Definitions?
The default channel groupings in Google Analytics are defined by a set of rules using the ‘medium’ parameter. A click or visit with an “email” as the medium parameter will fall under the Email default channel grouping. If you used “Email,” it will fall under the Other channel grouping. For more examples, check this table to find out which visit falls under which channel grouping.
What is not considered a default “medium” in Google Analytics?
There is a lot “medium” that’s not considered as a default value in Google Analytics. Take a look at this table to see which mediums are recognized by GA. If it’s not there, it’s not a default medium.
Why aren’t the default channel groupings showing in my account?
The reason why the default channel groupings are not showing up on your channel acquisition report is you do not have data that falls under it. If you don’t have ‘display’ data, you won’t see it there because there are zero values there anyway.
Why are my ads and social media campaigns showing in the Others channel?
If your campaign traffic are being categorized in the Others channel, you are most likely using custom parameters that are not the same as the default settings in Google Analytics. For example, using a “Email” as medium is different from “email.” The former will show up under the Others channel while the latter will be tagged under email traffic.
