Let’s get started.

What is marketing ROI? 

Marketing ROI, or marketing return on investment, is a key metric to determine how much return you get from marketing investments you make. 

For example, you set live a PPC campaign and it costs £500. You want to know how many sales you created on the back of this £500 investment.

The more sales you make, the more successful the campaign is. Marketing ROI helps you understand just how many sales and how much revenue you’re driving through marketing. 

How to calculate marketing return on investment

Calculating return on investment is easy. All you need to do is subtract your marketing cost from your sales. You then divide that figure by your marketing cost. 

(Sales Growth – Marketing Cost) / Marketing Cost = ROI

This calculation can be applied to all of your marketing, or you can break it down by channel or even campaign to understand your ROI on a holistic or individual basis.

There are a few key factors why marketing ROI is so difficult to track. We’ve broken it down to four main reasons: 

Your data is disconnected

This is a key one. Your lead and marketing data is out there. But, it’s disconnected. And it’s disconnected at every stage. 

Take this example. A user engages with your website a number of times before they convert via a form fill. 

While you might be tracking the form fill, how do you connect that lead conversion to the rest of their customer journey? 

And then, when that lead converts into a sale, how do you connect that closed revenue to the full customer journey too?

Lack of offline conversion tracking

While you might be able to track conversions like forms, what about more tricky-to-track conversion types like phone calls? 

Google Ads’ call tracking isn’t enough.

And without proper call tracking, or proper conversion tracking for that matter, you’re never going to be able to get a true marketing ROI.

Long sales cycles and the inability to view full customer journey 

Let’s say you were already tracking conversions and you could see which channel caused that conversion. 

That’s a great start to getting an accurate marketing ROI. But how often do customers land on your website and convert right away? When you need to generate leads, very rarely. They’ll likely have had some exposure to your business already. 

But, with long sales cycles meaning you can’t track conversions as they’re out of regular attribution windows, and a missing view of full customer journeys, your perception of how your marketing is functioning is wrong.

A user could visit your website for the first time via a PPC advert and then engage with you 50 more times.

Then, they could wait six months before returning to your site directly and converting. 

Without the right tools in place, you’d attribute this sale to direct. But we know that isn’t accurate. 

How to accurately track your marketing ROI 

To find out our true marketing ROI, you need to be able to track your leads from marketing to sales.

Normally, marketing generates leads and throws them over the wall to sales.

It leaves sales missing key data about their new leads.

And, it leaves marketing missing data on how their efforts are working to drive low or high-quality leads that are resulting in revenue.

The missing link is marketing attribution.

Marketing attribution is a way to track each and every lead, and, each and every touchpoint. It means you can get full visibility of your leads and their interactions with your content. Finally.

Ruler uses a closed-loop model that allows your team to quit reporting on clicks and conversions, and start reporting on what matters the most to your business: revenue.

How does it work? It’s simple.

Ruler Analytics tracks anonymous visitors to your website over multiple sessions, sources and keywords.

When a user converts into a lead, whether that be via phone call, form or live enquiry, Ruler Analytics will integrate with your chosen CRM (or wherever you’re storing your lead data) and fire the relevant data over.

Once the deal or sale closes into revenue, Ruler Analytics passes the monetary information back to your marketing analytics tools, like Google Analytics and ad platforms so you can report on real sales and revenue.

It’s this framework that simplifies the process when it comes to calculating the return on investment of your marketing efforts.
