What makes some one a SEO Specialist

[mantra]

Ofcourse SEO is the most talked topic in the webmaster forum, but very much less in this forum, I would like to ask you what makes actual SEO expert.

What qualification do you need to have for a person to be a SEO specialist ?
What does he should do reviewing the part time SEO ?

no you are absolutely wrong.

One can be called a SEO specialist if he/she is actually knowing about search engines main factors which can affect your site's PR.
