Why is web site structure important for Search Engine Optimisation?

There are many design techniques that can be used to build a website. These techniques are what we collectively refer to as web site structure. The 3 techniques that hinder SEO are frames, layers and dynamic pages.

A framed site is one where the page being viewed is actually a collection of pages pieced together. These are usually identified when you see a section of page remain still whilst you are scrolling.

SEO Problem
Search engines are unable to piece pages together to form a framed page. Therefore they are unable to fairly rank a web page that is in frames. Framed pages are at an enormous disadvantage with SEO and should be removed.


Layers allow designers enormous flexibility when placing information and graphics on a web page.

SEO Problem
Layers can be used to hide information. For this reason search engines heavily penalise web sites that contain layers.
