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.

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.
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
Layers allow designers enormous flexibility
when placing information and graphics on a web page.
Layers can be used to hide information. For
this reason search engines heavily penalise web sites
that contain layers.
