Both are digital designs, but a marketing website and an application require two completely different mindsets.
A marketing website typically serves a single visit to drive customers to action, so the focus is on the clarity of the message and conversion rate. Digital products used repeatedly, like apps or platforms, are different: customers return multiple times, so the concern is ensuring they quickly see value, can easily repeat tasks, and have reasons to stay. Misplaced investment, even with beautiful design, still won't yield the desired results.
When you say "I need a digital experience design," the first question to ask is: do your customers visit once to do something, or will they return to use it daily? That answer determines the entire design direction, the tracking metrics, and the level of complexity to invest in. These two types may seem similar on the surface because they are both digital interfaces, but the underlying logic is completely different.
A marketing website serves a short journey: customers find you, learn about you, then take action, which could be contacting you, making a purchase, or signing up. Most customers only visit once or a few times. Therefore, every design decision must serve the goal: is the message clear, does the flow lead correctly, can customers do what you want?
Digital products that are used repeatedly, such as management apps, membership platforms, work tools, serve a much longer journey. Customers return dozens, hundreds of times. Each redundant action in one use will multiply with the number of times customers return. The focus now is no longer on "is there immediate action" but on "do customers quickly see value" and "do customers have a reason to stay."
For complex business applications like banking software or enterprise resource planning, the core of the product is business logic, data, and security. That is the domain of specialized software developers. Experience design is just one layer within that, so you need to find the right engineering team before thinking about the interface.
The conversion rate measures what happens after a customer visits the page, heavily influenced by design. This is a key metric to determine if the website's experience strategy is effective.

For complex business applications like banking software or enterprise resource planning, you need a specialized software developer. Marketing websites, landing pages, and digital products tied to brand positioning fall under the domain of experience design, while the core business logic, data, and permissions belong to the software engineering team.
Apply both, but in the right places. The marketing website needs clear messaging and guides customers into the application, while the backend application must ensure new customers quickly see value and have reasons to return. These two parts serve different stages in the customer journey, so they should be measured by two different sets of metrics.
For marketing websites, page views indicate traffic but do not show whether customers take action. A more important metric is the conversion rate, which is the percentage of customers who actually do what you want after visiting the page. For repeat-use digital products, page views become less meaningful; it is essential to track retention rates and the level of customers returning to complete tasks.
