I would recommend to keep a custom definition for keywords kind of things
and hence \maketitle too in your custom *.cfg since each document class has
its own front matter setup. My bbb.cfg would look like:

%----------- begin bbb.cfg -----------
\makeatletter
\Preamble{xhtml,docbook-mml}

\def\hn{\HCode{\Hnewline}}

\def\maketitle{\IgnorePar\Tg<info>\hn
    \printkeywords
    \Tg</info>\hn
    \ShowPar}

\def\keywords#1{\gdef\@keywords{#1}}%
\let\@keywords\@empty

\def\printkeywords{\ifx\@keywords\@empty\relax\else
   \Tg<keywordset>\hn
   \@for\@kwd:=\@keywords\do
    {\Tg<keyword>\@kwd\Tg</keyword>\hn}
   \Tg</keywordset>\hn
   \fi}

\begin{document}

\EndPreamble

\makeatother

%---------------- end --------------

\printkeywords will parse your comma separated keyword list and tag each
keyword individually.

Your source document will look like:

%-----------------begin x.tex ------------
\documentclass{article}

\begin{document}

\keywords{aa,bb,cc,dd,kkk}

\maketitle

hello

\end{document}

%---------------- end ---------------

The output generated by  the command, htlatex x bbb, will look like:

<?xml version="1.0" encoding="iso-8859-1"?>

  </head>
  <body>
    <info>
      <keywordset>
        <keyword>aa</keyword>
        <keyword>bb</keyword>
        <keyword>cc</keyword>
        <keyword>dd</keyword>
        <keyword>kkk</keyword>
      </keywordset>
    </info>
    <!--l. 11-->
    <p class="indent">hello</p>
  </body>
</html>
