Purchase funnel and business management
We present the sales funnel as an alternative model of the consumer journey,
its essence, and its role in business.
What is the Sales Funnel?
The sales funnel is a marketing model that represents the movement of a buyer through the stages of the sales process, from the first contact to the completion of the transaction.

The term was initially proposed in 1898 by E.S. Lewis as the "consumer funnel," which indicated the buyer's journey from consideration to purchase—awareness, interest, desire, and action.

What does the sales funnel look like?

The graphic representation of the funnel resembles an inverted pyramid, which can be visualized as follows:

There are many interpretations of this method in professional literature that describe the different stages/phases of the funnel, but they all share a common feature: the number of initial contacts always outweighs the number of actual buyers.

To explain this with the above example, in the first stage, there will be all the people who have a demand for our product (e.g., 1000 people).

However, not all of them know about our store (e.g., 700 people).

Of course, not all of those who know about us will make a purchase. One might find the store’s location inconvenient, another might not like the reviews about us, and a third may simply lack the financial resources. As a result, only a small portion will actually visit our store (e.g., 300 people).

»
We can see that at each stage, there’s a "filtering" of customers who, for various reasons, don’t meet certain criteria. In this example, only 7% of those who initially showed interest in our product end up making a purchase.
The sales funnel doesn't close just by customers walking into the store. We need to guide them towards taking action and turning them into buyers. At this stage, some may not like the quality of the product, others might find the price or service unappealing, and in the end, only a portion of the customers will actually make a purchase (e.g., 70 people).
This is why the earlier stages of the funnel are wider than the later ones, and this is typically the shape of the sales funnel.

Why is the sales funnel necessary?

The funnel is a perfect tool for analyzing the effectiveness of each stage of the sales process, from the first contact to the final sale. It helps identify where the greatest loss of potential customers occurs, uncover the reasons for that loss, and draw conclusions about the quality of management and the intensity of efforts applied at each stage of the sales process. A clear understanding of the funnel not only helps pinpoint the reasons for failures post-factum but also allows businesses to forecast potential losses and take proactive measures to prevent them.


What stages does the sales funnel include, and how to create your own?

It should be noted that there is no universal funnel schema, as each business is unique in terms of its scale, industry, communication channels, sales process, and so on.
In one case, it could be an online store with various advertising channels that lead to the website, and in this case, the customer interaction chain is quite long (for example: viewing the ad – clicking through to the site – browsing the catalog – adding the product to the cart – registering – placing the order, making payment).

Another example could be a local beauty salon without any communication channels, and the chain is shorter: awareness of the salon – visiting/using services – making payment.


How to create your own funnel

Only one step is needed – to visualize the customer journey, break the business into stages (considering the existing communication channels), and select the most measurable ones. The journey starts with the first stage – identifying demand, raising awareness, and so on, and ends with the purchase.

What indicators should be measured

The sales funnel indicators can be classified into the following categories: quantitative and qualitative.

Conversion = Number of consumers moving to the next stage of the funnel / Number of consumers at the previous stage * 100%
Quantitative indicators

Certainly, the first step is to analyze the sales funnel data, meaning calculating the conversion from one stage to the next:

This allows you to calculate the percentage of potential customers who moved from one stage to the next (for example, from knowing about the store to visiting the store), identify problematic points, and work on improving them.

Quantitative indicators

Many forget that, in addition to quantitative indicators, there are also qualitative ones, which are even more important. It is the qualitative indicators that allow us to understand the reasons for losing customers. Clearly, the more demand there is for our product, and the more people know about us, the more people will visit our store and make a purchase. This is the theoretical part, but in practice, it often happens that months are spent on advertising, but when people come to the store, they don’t like the service provided by sales consultants. It is at this point that the majority of them are filtered out.

It is necessary to develop criteria for analyzing the qualitative component (website usability, order fulfillment forms, service quality, etc.) and continuously analyze each stage to enhance the qualitative aspect of the entire sales funnel.

For example, knowing that only 0.48% of people who are aware of the store make a purchase, two actions can be taken:
  1. Periodically increase the budget allocated for advertising campaigns to raise awareness, so that a higher percentage than 0.48% will make a purchase.
  2. Focus on improving the qualitative component of advertising campaigns, so that with the same budget, more people can be attracted to the product.
For this reason, it is important to remember that quantitative metrics can be the same for both you and your competitors and typically have a maximum limit. On the other hand, working on quality provides a unique opportunity to get ahead. As a reward, you will gain the ability to select the best customers and staff, thereby increasing your chances of outperforming your competitors.
Focusing only on the numbers without understanding their connection to the final result is equivalent to ordering one kilogram of food at a good restaurant.

How to calculate the metrics

When running offline activities, numerical calculations can be a bit more complex, but it’s still possible to track visitor numbers through surveys (e.g., where they heard about you), offering discount coupons if customers provide their details, using QR codes, and so on.

When it comes to the internet, let’s consider a typical example of a sales funnel to determine the calculation methods.

In most cases, the sales funnel for online business development looks like this:

Below, we will discuss the calculation methods for each metric.

Website entries / effective impressions * 100% = conversion rate of "entries from effective impressions."
From the perspective of inclusivity and the identification of the number of views (using tools like "Yandex.Direct", Google Adwords, and other tracking and analysis tools), correctly configured cross-analysis—using tools like Yandex.Metrica, Google Analytics, and Carrotquest—allows for the calculation of effectiveness. These tools help determine how many customers visited your site (their gender, age, location, etc.), how many stayed on the site, how many left immediately, what queries led them there, which stage has the highest drop-off rate, and when customers are more likely to leave.

Targeted Transitions / Transitions to Website * 100% = Conversion from "Transitions to Targeted Transitions

To identify target conversions, you can set up goals within these tools. Goals might include actions like clicks, viewing 5 pages on the site, exploring a specific page, and other key user interactions.

Calls, inquiries / target conversions * 100% = conversions from "target conversion to calls/inquiries"

For calculating inquiries, the aforementioned tools are sufficient. However, if it's about phone calls, it's recommended to use "Call-tracking" tools, which will provide information on how many people have called and from which source – with keyword accuracy, the percentage ratio of target and non-target audience, etc. This information will help you reallocate
the advertising budget and focus on more effective channels.

Transaction / calls, inquiries * 100% = conversion from "inquiry to purchase

Call-tracking" also helps in monitoring the efficiency of the sales department's performance. The tools allow setting the wait time for calls, service quality, reasons for abandoning the purchase, and more.
If the customer’s funnel doesn't end here (and there's still the phase of visiting an offline store), QR codes, promo codes, or coupons available on the website can be used to track customers coming from the site (as mentioned above).

As we pointed out, it’s very important to monitor the qualitative aspect of each stage.

What to do next


It’s important to remember that the sales funnel is one of the most effective tools for business forecasting. Once you’ve gathered accurate data from the calculations, it helps continually increase conversion at each stage and differentiate yourself from competitors at every step. Thoughtful use of this tool will enable the business to reach a new level in a very short period.
