There is no doubt in the fact that effectiveness of a website is very much dependent on its navigability. So while designing a website make sure that all the navigational elements of your website are linked by menus and buttons.

In order to make a website design navigable to the visitors, certain rules have to be followed. Some of the desirable locations where navigation elements should be inserted are mentioned below:
* Top Menus- The top of the page menu bar is most of the time located directly under the site logo. These menu items may be expanding menus, drop down menus or single links.
* Left Side Navigation- Left side navigation is implemented as either a text area or a column. Just like the top menu, each of the items can be an expanding menu or a single link.
* Bottom Menus- It can either be footer or a menu bar. In most of the time menu bars use graphics. Sometimes it also uses text links while footers exclusively use text links.
* Right Side Navigation- This type of navigation is not used much, but whenever used, it is implemented as a text area (on the top right hand side of the web page) or a column. Most of the designers use this specific area for advertisements.

Important Navigation Related Factors

* Internal Page Links- Each and every web page should be within 2/3 clicks from the home page, whereas the important pages of a website should be only 1 click away from the home page.
* Log In Boxes- These boxes should be displayed prominently at the top right, top left or inside the page header.
* Shopping Carts- If your website has a shopping cart option, you should display a view cart button at the top right side.
* Order Buttons- These buttons should be large as well as visible.
* Breadcrumbs- Breadcrumbs should be located at the top left of the web page under the header.
* External Links- These links are most used inside a website's text area.
* Advertisements- it is better to use ads under the header banner. However, it is observed that advertisements "above the fold" are most effective.
* Site Map- A site map is indeed the best way to layout the full website for your visitor. It is merely a hierarchical listing of all the pages of a particular site with a click able hyperlink to that page.

Thus by keeping all those points in mind a good website design company develops a navigable website.
