You can insert META tags into the "header-insert"
Adin -> Edit 'header-insert'
Like here we have:
<meta name="description" content="Where UBB.Threads developers come for answers." />
<meta name="keywords" content="php, mysql, bulletin boards, forums, BBS, internet, online, discussion groups, newsgroups, ubb.threads, phpbb, vb, vbulletin, UBB, wwwthreads, ultimate bulletin board, customize, Perl, CGI, UNIX, NT, affordable, hacking, Infopop, community, UltimateBB, scripts, phpnuke, postnuke, threads, topics" />
The page title is the title of your site that you define in the config file.
