[Plugin: WP-PostRatings] Remove the excerpt and post title under the rate

Okay, i found it. But ive still the problem with Google Snippets. I have the excerpt in every post but its at another position.

Can i insert it like that:

$post_meta = ‘<meta itemprop=”name” content=”<?php the_title(); ?>”><meta itemprop=”description” content=”<?php the_excerpt(); ?>”><meta itemprop=”url” content=”‘.$post_link.'”>’;
