What are the major task of the professional SEO Expert ?

Hi !

On your point of view

What are the major task of the professional SEO Expert ? Is there any similarity between an SEO Expert and Web Designer ?

Web Designer will design and develop the website while SEO expert will optimize that website means increase link popularity and keyword ranking in different search engines..

All the seo expert think about ranking of web .

He must do the basic steps before starting off page seo...
Total analysis of site..its keyword with respect to competition and searches...
and then start its on paging....
then do off pages techniques....
