Fourth Chapter Lesson-4: Different structures of websites (Linear, Tree, Web linked, Hybrid).

At the end of this lesson-

  • 1. You will be able to explain different types of pages of a website.
  • 2. You will be able to explain structure of websites. 
  • 3. You will be able to explain different types of website structures.
  • 4. You will be able to analyze different types of website structures.


Website’s structure: A website’s structure refers to how the website is set up, i.e. how the individual sub-pages are linked to one another. It is particularly important that crawlers can find all sub-pages quickly and easily when websites have a large number of sub-pages.

For this reason, a website’s homepage needs to have links to the most important sub-pages. Based on the link of web pages, they are in different name. Normally there are three types of web pages in a website. For example- Home page, main pages and sub pages.


Home Page: A home page is a default or front page of a site that serves as the starting point of website. It is the first page that visitors see when they load a URL. It contains information about mission, vision, etc. and there is a menu bar where main pages are linked. This menu bar of the home page is called main section or “site index”.

Main pages: Main pages contain information about a particular division or section and the main pages are connected in a menu bar. For example- Web pages of different departments of a University are linked in the menu bar of the home page. This pages of different departments are called main pages.

Sub pages: Sub pages contain details information about a particular topic or subject and they are linked with main pages. For example-  Web pages of different departments of a University are linked in the menu bar of the home page. This pages of different departments are called main pages. Again there are some pages that contain detail information about admission, syllabus, notice etc. of a particular department and they are linked with main page. Then these web pages are called sub pages.


There are four types of website’s structures according to the characteristics of websites. They are –

  • 1. Linear/Sequential structure
  • 2. Tree/Hierarchical structure
  • 3. Network/Web linked structure
  • 4. Hybrid/Combinational structure


Linear/Sequential structure: The simplest and most familiar way to organize information is to place it in a sequence. This is the structure of books, magazines, and all other print matter. Sequential ordering may be chronological, a logical series of topics progressing from the general to the specific, or alphabetical, as in indexes, encyclopedias, and glossaries.

Straight sequences are the most appropriate organization for training or education sites, for example, in which the user is expected to progress through a fixed set of material and the only links are those that support the linear navigation path.



Tree/Hierarchical structure:These are possibly the most common types of website structures. Because web sites are usually organized around a single home page, which then links to subtopic menu pages, hierarchical architectures are particularly suited to web site organization. Sometimes this structure is called tree structure, and it is very familiar in corporate and institutional life, so most users find this structure easy to understand.

Most web sites adopt some form of multi tiered hierarchical or tree architecture. This arrangement of major categories and subcategories has a powerful advantage for complex site organization in that most people are familiar with hierarchical organizations, and can readily form mental models of the site structure.



Network/Web linked structure: In this structure, all the web pages of a website are linked with each other directly. The frame is used to present the links in a list. This frame remains fixed and if a link is clicked, the web page is displayed in the large frame.

It is the most impractical structure for web sites because they are so hard for the user to understand and predict. This structure works best for small sites dominated by lists of links and for sites aimed at highly educated or experienced users looking for further education or enrichment and not for a basic understanding of a topic.


Hybrid/Combinational structure: In this structure, web pages of a website are linked using different multiple structures. Today most of the websites follow this structure. For example- some pages are linked in sequentially and some are linked in hierarchically.
