Please Help: Got Data that Shows SEO Works?

[wen j]

Hello, I need data to show my boss that SEO increases desired traffic to our website in general. More importantly, I need data on the effectiveness of particular SEO strategies. If you can, please provide clues or direct links to reports or researches done on SEO, its strategies, and its effect on the traffic of tested sites. Much appreciated!

I think Google will get you all this. Not sure if everything can be found on a single site.
