Page Title and Descriptions

Hi

I'm using the following on each page;

<title><?php perch_pages_title(); ?></title>
<?php     
perch_page_attributes(array(        
  'template' => 'seo.html'    
)); 
?>

I've entered the title and descriptions for each page in Page Options, but checking the page listings in google, only the titles are showing... the description is just picking random sentences from the page.

The site is new and was freshly indexed by google.

Do I need to do something else to get the descriptions to work?

Thanks Wayne
