Google Analytics Attribution provides you with a holistic view of your marketing performance across multiple channels.

Attribution in Google Analytics is a powerful feature that provides you with better visibility into the full customer journey across several touchpoints.

When used correctly, it can help you understand how different marketing channels impact your traffic and conversions, allowing you to see where you’re getting the greatest return from your investments.

What is Attribution in Google Analytics?

There are many touchpoints through which users can interact with your brand. As a result, customer journeys can take any form and often last days, weeks, sometimes even months. In fact, during a study, we found that nearly 20% of companies endure sales cycles lasting more than four months.

Google Attribution was released to simplify the complex issues surrounding multi-channel reporting. Attribution aims to help marketers gain a better understanding of how multiple channels contribute to the customer journey.


Tracking customer journeys allows you to gain a deeper understanding of your visitors and unlock valuable data about their interactions and behaviours. Download the guide below and follow the complete lifecycle from awareness to purchase.

How to track and compare your customer journeys

There are five reports available in Attribution:

What problem does Google Attribution aim to solve?

By default, Google Analytics uses the last-click attribution model. All credit is assigned to the last channel a user engaged with, and any previous interactions are ignored.

In theory, last-click attribution seems like the best way to measure the performance of your marketing channels, but it doesn’t tell you the full story.

If you only pay attention to last-click attribution, you are effectively ignoring the performance of your entire marketing activity.

Let’s say, for example, Jamal sees an advert for a car on Instagram. He clicks through to the website to view more vehicles. He doesn’t enquire on the initial visit because he needs to do more research on the brand before making his final decision.

He does, however, sign up for an email newsletter where he’s sent a discounted deal on a particular car. A week later, Jamal completes a brand search in Google, clicks on an organic listing and ends up filling out an enquiry form.

If you were to use the last-click model in Google Analytics, then the credit for the form enquiry would go to organic search, ignoring both Instagram and the newsletter.

Though you can agree, Instagram and the newsletter played a huge role in Jamal’s customer journey.

Last-click attribution doesn’t provide a clear picture of where your sales are coming from, or how customers move through the funnel.

However, with Google Attribution, users can look beyond last-click and make smarter decisions based on full-funnel attribution data.

Rule-based attribution models available in Google Analytics

Creating and comparing attribution models in Google Analytics is key as it provides you with a clear view of how each channel and campaign contributes to the customer journey. The following is a list of rule-based attribution models available in Analytics.

First-click: The initial touchpoint gets 100% of the credit. In this case, Google Ads would receive 100% of the credit for the sale.

Last-click: Similar to first-click, instead, the final touchpoint gets 100% of the credit. In this case, Facebook would receive 100% of the credit for the sale.

Linear: The credit for the conversion is divided equally across the customer journey.

Time decay: Each touchpoint receives credit. However, Analytics gives more weight to the interactions closest in time to the sale or conversion.

Position-based: 40% credit is allocated to the first and last click touchpoints, and the remaining 20% credit is distributed evenly across the other interactions.

All of these attribution models will generate various results, as they measure the value of your touchpoints differently. You can learn more about these attribution models and more in our guide to attribution modelling.

What is the data-driven model in Google Attribution?

Unlike other models we’ve discussed, Google’s data-driven attribution analyses all of your marketing touchpoints.

It considers factors such as time from conversion, device type, number of ad interactions and more.

The data-driven model distinguishes what happened from what could have occurred to conclude which touchpoints are most likely to drive conversions. Let’s say Ella wanted to buy a new pair of shoes.

Ella starts her journey on Google using the search term “latest shoes for women”. She clicks on a paid ad and browses the website.

Ella finds a pair of shoes that she likes but doesn’t purchase them straight away. Later that day, Ella returns to Google.

This time, Ella completes a brand search, and instead clicks on an organic listing. Ella finds the shoes and makes a purchase.

Using a data-driven attribution model you can gain a better understanding of Ella’s journey and your customers path to conversion.

Using your unique account data and machine learning technology, Google can analyse both converting and non-converting pathways to learn how different touchpoints impact conversion outcomes.

Such technology allows Google to assess and calculate the contribution of each click interaction more accurately.

The limitations of Google Analytics Attribution

Google Attribution has made it possible for marketers to measure the effectiveness of their marketing across various touchpoints at no additional cost, but it isn’t perfect.

Attribution window limited to 90-days

Many apps use a default attribution window of 30-days, including Google Analytics.

When you set up conversion tracking in Google Analytics, your attribution reports automatically show how users engage with your digital channels for up to 30-days before a conversion takes place.

You can, however, adjust this between 1 to 90 days.

If your company sells a high-value service or product, chances are your sales cycle is long and drawn out across many months.

Often longer than 90 days.

Why is this important? Well, let’s say a user visits your website for the first time via a PPC ad. They navigate around your website but don’t convert.

After three months, that same user returns to your website via an organic search.

They fill out a form to learn more about your services and end up converting into a customer.

Even though there are two crucial interactions, Analytics would only have a recollection of the organic touchpoint as the ad click happened beyond the 90-day timeframe.

Lack of offline tracking capabilities

Google Analytics, in particular, does a good job of collecting online conversion data such as form completions. However, when the subject of offline conversion tracking comes up, many marketers get that glazed​-over, deer-in-the-headlights look in their eyes.

While there are many digital channels through which your customers can get in touch with you, phone calls remain a popular and preferred method of communication.

That said, offline conversions are often deliberately ignored, mainly because marketers lack the infrastructure and knowledge to set up and track offline conversions in Google Analytics. But, by not tracking calls, marketers are missing as much as 80% of conversions.


Without offline conversion tracking, it’s likely you’re not getting a true picture of your lead generation performance. But, it doesn’t have to be difficult with the right tool in place.

Google Attribution needs a sufficient amount of data

Google’s data-driven model needs sufficient data for it to work successfully.

You must have at least 15,000 clicks and 600 conversions within 30-days to be eligible for this attribution model.

If your conversion data doesn’t meet the required threshold, then unfortunately, you can’t take advantage of the opportunities of data-driven attribution in Google Analytics.
