Digital marketing has an attribution problem. We’re stymied by encrypted search, which takes away our ability to detect basic information about where our visitors are coming from or what they searched for. We’re challenged by dark social, which takes away search and attribution data from mobile apps like WeChat, WhatsApp, etc.

Social analytics company Radium One estimates that as much as 3/4 of all social media traffic is dark social, social media which lacks attribution because it’s passed around in one-to-one messages:


These trends create consequences we see in our Google Analytics. A significant portion of my website traffic is showing up as direct/none. Google isn’t sure what this data is, because it’s coming through without attribution. Is it from Facebook? Twitter? Safari on mobile devices? I don’t know:

Marketers like you and me are feeling the pressure to show ROI up and down the funnel and develop comprehensive attribution models. We can’t go to our stakeholders and say, “Well, we don’t know what’s going on with 75% of our marketing”. Guesswork doesn’t make for great marketing.

What can we do to mitigate the impact of these attribution problems? We must tag everything we do, so that if someone shares our content, we attribute it as best we can. My current recipe for tagging is using Google Analytics UTM tagging for everything, combined with a link shortener like Why a link shortener? Some software removes or rewrites attribution tags if they’re openly readable in the URL. By shortening the links, we preserve our attribution.

Here’s an example. I start with a list of links I’ll be sharing on Facebook, though it could be anything from my email newsletter to a blog post:


Using my links generating script, it appends all my tracking codes and shortens them:

Visiting any of these links shows my attribution in the final URL:

Obviously, this example doesn’t do anything for my own analytics because this is a third-party website, but if this were my own blog post, I’d have attribution on the shared link, the link. Anyone else sharing it would preserve that attribution as well, even if they shared it in WhatsApp.

If you’re thinking of becoming an “influencer”, you must attribute like this. If you use attribution tagging like the above example, you’ll stamp all the traffic you generate with your name and brand. Imagine when a digital marketer looks in their Google Analytics and sees your name generating lots of traffic to their website. Will they continue working with you? You bet.

Until attribution is fixed by the major Internet hubs, we’ll need to resort to building our own attribution systems. It’s the fastest, easiest way to ensure that we’re getting credit for our work, whether we’re in-house marketers, agencies, or influencers.
