Run this:

#+BEGIN_SRC emacs-lisp :eval never-export :exports none
  (require 'ob-org)
  (defun eval-if-html ()
    (if (not (eq org-export-current-backend 'html)) "never"))
#+END_SRC


Then export this with the html backend:

#+OPTIONS: toc:nil

#+BEGIN_SRC org :eval (eval-if-html) :exports results :results replace
  ,* HTML only heading
  Text which should appear in HTML exports, but not \LaTeX{}.
#+END_SRC

and you will get this:

<div id="outline-container-org1e9ad24" class="outline-2">
<h2 id="org1e9ad24"><span class="section-number-2">1</span> HTML only 
heading</h2>
<div class="outline-text-2" id="text-1">
<p>
Text which should appear in HTML exports, but not \LaTeX{}.
</p>
</div>
</div>

With other backends you get nothing.

HTH,
