Does usability in Online Marketing begin with Website?

I am in Singapore right now and will be speaking about "SEO and usability" at SMX Singapore on Monday.

I have been doing some research on SEO and usability in preparation for my talk, and have been very surprised to find that most people think about usability starting with the website. Also, usability is looked at as a feature of what the web-designer provides.

As I have mentioned on this blog previously, for myself and the OMLogic team, usability starts with Search Results (Essentially Title / Description) and is an ESSENTIAL function of Search Engine Optimizer. Please refer to the following link http://anky-pc/oml-blog/seo/the-art-of-not-writing-title-descriptions-for-seo for more information on our usability Philosophy starting with search results.

I want to use this blog to get feedback from our readers about what are there thoughts on SEO incorporating usability as a key feature of there work?
