The names describe different jobs
A website presents information across several pages. A landing page focuses on one campaign or action. A web application allows users to complete an ongoing task through software in a browser.
Choosing the wrong product can create unnecessary cost or leave the business without the function it actually needs.
A business website explains the organization
A website usually includes the company, services, leadership, proof, contact information, and supporting resources.
It is appropriate when visitors need to explore several subjects, compare services, verify credibility, and return for different reasons.
A landing page supports one campaign
A landing page is designed around one audience and one main action, such as requesting a consultation, registering for an event, buying a product, or downloading a resource.
It can be part of a larger website or operate as a focused campaign page. It should remove unnecessary choices rather than reproduce the entire company site.
A web application performs a function
A web application may allow users to log in, manage information, complete transactions, generate reports, collaborate, book services, or operate a business workflow.
It requires product planning, user roles, data structure, security, testing, maintenance, and continuing development beyond ordinary page design.
A portal is a controlled access point
A client or employee portal may provide documents, messages, reports, payments, project updates, or internal tools.
It can be a section of a web application and may connect to existing business systems.
Ecommerce adds commercial infrastructure
An online store needs products, payments, taxes, shipping, inventory, customer records, order communication, and returns processes.
It may use an existing ecommerce platform or require custom development depending on the business model.
A mobile application is a separate decision
A mobile app is installed on a phone or tablet and may use notifications, offline access, location, camera, or other device features.
Many businesses can serve users through a responsive website or web application without the cost of maintaining separate mobile apps.
Use the simplest product that solves the problem
A landing page should not become a custom application because the project sounds more advanced. A business should not force a complex customer process into a normal contact page when software is genuinely required.
Define the user, action, data, frequency, security, and long-term maintenance before selecting the format.
The products can work together
A company website can establish credibility, a landing page can support a specific campaign, and a web application can deliver the service after the customer signs in.
