<ul> <li> H2</li> </ul>

lists and H tags

[OddDog]

I have a long list, and would like to add h2 and h3 tags for SEO

Any thoughts ...

I'd say use a h2 ahead of your list and use h3 tags for nested lists. Something like that. Although it looks a bit strange and I wonder if it's semantically correct.

<h2></h2>
<ul>
<li></li>
<li>
<h3></h3>
<ul>
<li></li>
<li></li>
</ul>
</li>
</ul>

I think that it would just look a bit strange and any SEO benefit would be slim at best.
