In in includes/functions.php, you'll find some pretty obvious code you may want to modify upon your needs :
$this->meta['meta_title_def'] = $config['sitename'];
$this->meta['meta_desc_def'] = $config['site_desc'];
$this->meta['meta_keywords_def'] = $config['site_desc'];
$this->meta['meta_lang'] = $config['default_lang'];
$this->meta['meta_cat'] = 'general';
$this->meta['meta_robots_def'] = 'index,follow';
$this->meta['meta_distrib'] = 'global';
$this->meta['meta_restype'] = 'document';
$this->meta['meta_copy'] = $config['sitename'];
You'll as well find some setting you may want to change (default are good) :
/**
* Some config :
* => keywordlimit : number of keywords (max) in the keyword tag,
* => wordlimit : number of words (max) in the desc tag,
* => wordminlen : only words with more than wordminlen letters will be used, default is 2,
* => bbcodestrip : | separated list of bbcode to fully delete, tag + content, default is 'img|url|flash',
* => ellipsis : ellipsis to use if clipping,
* => topic_sql : Do a SQL to build topic meta keywords or just use the meta desc tag,
* => check_ignore : Check the search_ignore_words.php list.
* Please note :
* This will require some more work for the server.
* And this is mostly useless if you have re-enabled the search_ignore_words.php list
* filtering in includes/search/fulltest_native.php (and of course use fulltest_native index).
* => bypass_common : Bypass common words in viewtopic.php.
* Set to true by default because the most interesting keywords are as well among the most common.
* This of course provides with even better results when fulltest_native is used
* and search_ignore_words.php list was re-enabled.
* => disallowed : Disallow tag based on GET var used : varname => 1|0, 1 will through a disallow meta tag.
* Some default values are set bellow in the seo_meta_tags() method
