A one-page site is a site that consists of one short or long page and pursues a commercial purpose. According to Internet marketers, this format of the site allows you to attract the attention of visitors to its subject matter as much as possible. A single page or Landing Page (landing pages) is created for a single product that needs to be either sold quickly if it is already known to the target audience, or to increase its recognition and popularity if it is a novelty on the market.

A multi-page website is a serious tool for companies that have a lot of goods and services that need a full presentation. A single-page page is not suitable for such purposes, since there simply won't be enough space on it, and an overabundance of information for landing is not the best quality. Multi-page resources are not only a platform for promoting goods and services, but also an indicator of the seriousness and high status of the company.

An online store is a website with products presented on it, where the buyer can choose and pay for the goods. This type of site is considered complex in its design, because it has a branched structure with many transitions. The main advantage of this type of trade is that there is no need to hire a large number of staff, rent a building and have a warehouse with stocks. For the buyer, shopping without leaving home becomes an absolute plus.

Website design is the design of content, the totality of all graphic elements on a web page. Previously, web design was understood exclusively as visual design, but now user convenience has come to the fore, so analytics and competent structuring of information on the site have been added to the tasks of a web designer.

The main task of the design is to introduce the user to the page. It facilitates user interaction with the web page, which means it has a positive effect on conversion and behavioral factors. Thoughtful design creates the right impression about the company.

Adaptability is the ability of a site to "adapt" to various technical conditions (namely, to the screen size of a user device). An adaptive website looks good on a desktop monitor (a regular PC), on a tablet computer, and on a smartphone screen. Moreover, the quality of the display does not depend on either the diagonal or the positioning of the screen.

Adaptive layout is a way of creating web pages in which they automatically adjust to the size and orientation of the device screen, and their design varies depending on the user's actions.

The goal of adaptive layout is to ensure that the site remains user-friendly and ensures conversion when loading on different devices.
