the page optimization will not happen automaticly, you need to add the meta tags and use the WebAssist -> CMS -> Insert Comment From Power CMS to addd the meta tag information.
go to WebAssist -> CMS -> Insert Comment From Power CMS, and select content then select the meta key word content area.
this will add code to the page similar to:
<?php echo WA_getCMSContent($database_PowerCMSConnection, $PowerCMSConnection, 'testing', 'meta-keywords'); ?>
add that to the content of a key word meta tag.
<meta name="keywords" content="<?php echo WA_getCMSContent($database_PowerCMSConnection, $PowerCMSConnection, 'testing', 'meta-keywords'); ?>" />
do the same for the description and title:
<meta name="description" content="<?php echo WA_getCMSContent($database_PowerCMSConnection, $PowerCMSConnection, 'testing', 'meta-description'); ?>" />
<title>
<?php echo WA_getCMSContent($database_PowerCMSConnection, $PowerCMSConnection, 'testing', 'meta-title'); ?>Untitled Document
</title>
bear in mind, my example is using a content area named testing, your code may be different.
