Assisted Conversions – What Are They and Why Should You Care?



[Update – 9th November 2012] Google has made the attribution modelling tool available to all users. This enables much quicker and sophisticated analysis of assisted conversions data.

With the shiny new Google Analytics interface came several new features including real time Analytics and Assisted Conversions. While there’s no doubt the former is hugely important in assessing the immediate result of various activity (e.g. social or a TV ad), it was the latter that was of the most interest to us. Assisted conversions give us a whole new level of data and enable us to attribute sales or enquiries more accurately to the marketing channel or channels that generated them. This is particularly important in accurately measuring the success of SEO, Conversion Rate Optimisation, PPC, social media and a host of other digital marketing channels.

What Are Assisted Conversions?

Assisted conversions within Google Analytics enable you to gain further insight into the complete conversion path of visitors to your site. Let’s consider the following perfectly feasible scenario:

This would have previously been attributed as a brand organic conversion because that was the last interaction the user had with your site before converting to a sale.

However, it’s fair to argue here that had that user not first found you via a generic, non-brand search for which you were appearing on the paid ads, he or she may never have converted. So while the ultimate conversion can be attributed to a brand organic visit, there has to be at least some indirect attribution to PPC as well.

The same can happen in a multitude of different ways. For example:

  • A user finds you by organic first then converts after a visit via a social networking site.
  • A user finds you via non-brand organic and then returns by a brand PPC ad to make a purchase
  • A user first comes across you on another site, visits as referral traffic from that site and leaves without making a purchase. He or she then searches a non-brand keyword, finds you in the organic listings, remembers seeing you before, clicks on your site and makes a purchase.

All of those are common scenarios.

Assisted conversions make this data visible.

In the image below taken from the Analytics account for 8Ball Tshirts (used with consent – numbers removed to protect client confidentiality) you can see the channels that have assisted in goal conversions.

The data available here is:

  • Assisted conversions –  how many conversions were ‘assisted’ by each of the channels listed
  • Assisted conversion value – the total value of the conversions assisted by the channel
  • Last interaction conversions – how many conversions were completed by the listed channels
  • Last interaction conversion value – the total value of the conversions completed by the listed channels.
  • Assisted/Last Conversion Interactions – The ratio of assisted/last interaction conversions.  This is a number that indicates whether this channel is primarily results in last interaction conversions or is predominantly assisted conversions. Numbers of 1.5 and higher indicate that this channel is predominantly accounting for assisted conversions, while numbers closer to 0 indicate the channel’s contribution to conversions is predominantly as last interaction.

Top Conversion Paths

Within Google Analytics, it is possible to delve even further into the ‘multi channel funnels’ section than just the high level view above. One particularly useful feature is Top Conversion Paths, which allows you to see the most common user paths from visit to sale/goal.

For example, from 8Ball’s Analytics, we can see again that there were 1,479 different multi visit paths that led to a conversion over the dates we’re analysing and that the most common of these was someone visiting first through organic and then making another visit through organic before making a purchase. This was closely followed by users visiting through organic first and then returning directly to the site later to make a purchase.

Path Length

Another excellent bit of data is presented in Google’s ‘path length’ section, where you can see how many touch points are most common for users before making a purchase/converting.

Again, we’ve removed actual figures in order to protect the confidentiality of 8Ball. But what we can clearly see is that fewer than half of 8Ball’s conversions occur on the first user visit (47.94% to be specific). The rest are accounted for by people visiting more than one – in a handful of cases by people who visit 12 or more times before committing to buy

Time Lag

With the above data on path length in mind, it might come as a surprise that many of these multi touch point buyers actually make their many different channel visits in the same day.

Time lag tells us how much time passes (within the 30 day period than an assisted conversion path is tracked) between the first touch point and the sale.

Data Limitations

Within Google Analytics, there are some limitations (albeit minor ones) to this data:

  • Assisted conversion paths can only go back as far as 30 days. So if someone has first visited your site more than 30 days ago, their first touch point won’t be showing up. Instead it will be the first touch point within the last 30 days.
  • Data is 2 days out of date. Google acknowledges that data is 2 days behind within assisted conversions and advises users to take note of this when analysing.

Why Should You Care About Assisted Conversions?

Conversion attribution has always been challenging. If you only ever look as far as ‘last click attribution’ (i.e. you consider the last means by which someone arrived at your site to be the single reason they converted) you risk cutting off marketing channels you deem ineffective and then finding this has a knock on negative impact on your enquiries or sales from other channels.

Assisted conversions give you a fuller picture and enable you to see what’s actually driving sales and how users find you. The data makes it clear that, as we already knew, users shop around, and simply attributing a sale to the last visitor touch point is too narrow a focus and too simplistic a view in measuring the true value of your various digital marketing channels.

    While it’s good to have words on your site, but copywriting isn’t just about filling up the page with words and moving on to the next task. There’s so much more to copywriting than hammering the keyboard for eight hours a day. Fulfilling the task requires a lot more than hitting the word count.


    Search Engine Optimisation is an ongoing process and in order to get the most out of your results, you need to have a long term strategy in place. On the other hand, almost all new websites can benefit from an SEO boost in their baby stages.
