The first is that it’s caused almost exclusively by users typing an address into their browser (or clicking on a bookmark). The second is that it’s a Bad Thing, not because it has any overt negative impact on your site’s performance, but rather because it’s somehow immune to further analysis. The prevailing attitude amongst digital marketers is that direct traffic is an unavoidable inconvenience; as a result, discussion of direct is typically limited to ways of attributing it to other channels, or side-stepping the issues associated with it.
In this article, we’ll be taking a fresh look at direct traffic in modern Google Analytics. As well as exploring the myriad ways in which referrer data can be lost, we’ll look at some tools and tactics you can start using immediately to reduce levels of direct traffic in your reports. Finally, we’ll discover how advanced analysis and segmentation can unlock the mysteries of direct traffic and shed light on what might actually be your most valuable users.
What is direct traffic?
In short, Google Analytics will report a traffic source of “direct” when it has no data on how the session arrived at your website, or when the referring source has been configured to be ignored. You can think of direct as GA’s fall-back option for when its processing logic has failed to attribute a session to a particular source.
To properly understand the causes and fixes for direct traffic, it’s important to understand exactly how GA processes traffic sources. The following flow-chart illustrates how sessions are bucketed — note that direct sits right at the end as a final “catch-all” group.
Broadly speaking, and disregarding user-configured overrides, GA’s processing follows this sequence of checks:
AdWords parameters > Campaign overrides > UTM campaign parameters > Referred by a search engine > Referred by another website > Previous campaign within timeout period > Direct
Note the penultimate processing step (previous campaign within timeout), which has a significant impact on the direct channel. Consider a user who discovers your site via organic search, then returns via direct a week later. Both sessions would be attributed to organic search. In fact, campaign data persists for up to six months by default. The key point here is that Google Analytics is already trying to minimize the impact of direct traffic for you.
What causes direct traffic?
Contrary to popular belief, there are actually many reasons why a session might be missing campaign and traffic source data. Here we will run through some of the most common.
1. Manual address entry and bookmarks
The classic direct-traffic scenario, this one is largely unavoidable. If a user types a URL into their browser’s address bar or clicks on a browser bookmark, that session will appear as direct traffic.
Simple as that.
2. HTTPS > HTTP
When a user follows a link on a secure (HTTPS) page to a non-secure (HTTP) page, no referrer data is passed, meaning the session appears as direct traffic instead of as a referral. Note that this is intended behavior. It’s part of how the secure protocol was designed, and it does not affect other scenarios: HTTP to HTTP, HTTPS to HTTPS, and even HTTP to HTTPS all pass referrer data.
So, if your referral traffic has tanked but direct has spiked, it could be that one of your major referrers has migrated to HTTPS. The inverse is also true: If you’ve migrated to HTTPS and are linking to HTTP websites, the traffic you’re driving to them will appear in their Analytics as direct.
If your referrers have moved to HTTPS and you’re stuck on HTTP, you really ought to consider migrating to HTTPS. Doing so (and updating your backlinks to point to HTTPS URLs) will bring back any referrer data which is being stripped from cross-protocol traffic. SSL certificates can now be obtained for free thanks to automated authorities like LetsEncrypt, but that’s not to say you should neglect to explore the potentially-significant SEO implications of site migrations. Remember, HTTPS and HTTP/2 are the future of the web.
If, on the other hand, you’ve already migrated to HTTPS and are concerned about your users appearing to partner websites as direct traffic, you can implement the meta referrer tag. Cyrus Shepard has written about this on Moz before, so I won’t delve into it now. Suffice to say, it’s a way of telling browsers to pass some referrer data to non-secure sites, and can be implemented as a <meta> element or HTTP header.
3. Missing or broken tracking code
Let’s say you’ve launched a new landing page template and forgotten to include the GA tracking code. Or, to use a scenario I’m encountering more and more frequently, imagine your GTM container is a horrible mess of poorly configured triggers, and your tracking code is simply failing to fire.
Users land on this page without tracking code. They click on a link to a deeper page which does have tracking code. From GA’s perspective, the first hit of the session is the second page visited, meaning that the referrer appears as your own website (i.e. a self-referral). If your domain is on the referral exclusion list (as per default configuration), the session is bucketed as direct. This will happen even if the first URL is tagged with UTM campaign parameters.
As a short-term fix, you can try to repair the damage by simply adding the missing tracking code. To prevent it happening again, carry out a thorough Analytics audit, move to a GTM-based tracking implementation, and promote a culture of data-driven marketing.
4. Improper redirection
Once again, control what you can: use carefully mapped (i.e. non-chained) code 301 server-side redirects to preserve referrer data wherever possible.
5. Non-web documents
Links in Microsoft Word documents, slide decks, or PDFs do not pass referrer information. By default, users who click these links will appear in your reports as direct traffic. Clicks from native mobile apps (particularly those with embedded “in-app” browsers) are similarly prone to stripping out referrer data.
To a degree, this is unavoidable. Much like so-called “dark social” visits (discussed in detail below), non-web links will inevitably result in some quantity of direct traffic. However, you also have an opportunity here to control the controllables.
If you publish whitepapers or offer downloadable PDF guides, for example, you should be tagging the embedded hyperlinks with UTM campaign parameters. You’d never even contemplate launching an email marketing campaign without campaign tracking (I hope), so why would you distribute any other kind of freebie without similarly tracking its success? In some ways this is even moreimportant, since these kinds of downloadables often have a longevity not seen in a single email campaign. Here’s an example of a properly tagged URL which we would embed as a link:
The same goes for URLs in your offline marketing materials. For major campaigns it’s common practice to select a short, memorable URL (e.g. moz.com/tv/) and design an entirely new landing page. It’s possible to bypass page creation altogether: simply redirect the vanity URL to an existing page URL which is properly tagged with UTM parameters.
So, whether you tag your URLs directly, use redirected vanity URLs, or — if you think UTM parameters are ugly — opt for some crazy-ass hash-fragment solution with GTM (read more here), the takeaway is the same: use campaign parameters wherever it’s appropriate to do so.
6. “Dark social”
This is a big one, and probably the least well understood by marketers.
