Can you gives give me a hand?

Try http://seositecheckup.com/. They give you more info about your situation and how to improve it

An advice:  change your theme settings to only load javascript before the end of the body tag (ACP - Customisation - Themes - Click "Edit" on the theme you're using - under the custom tab.)
